CONNECTING MEMBER FOR END REGIONS OF LADIES UNDERWEAR

Abstract This invention relates to a connecting member for end regions of ladies' underwear which are to be interconnected, more especially the end regions of the wings of bras, said member comprising an eye tape, which is provided with one or more eyes and is connectable to a hook tape (2), said hook tape having two regions (7,8) situated one above the other, one or more hooks (3) being secured to one region, and the edge areas of both regions extending parallel to said hooks being interconnected by means of a respective joint weld (10). The Joint welds (10) are disposed inside the hook tape (2), between the hook-free region (8) thereof and the hook-carrying region (7).
Full Text Connecting element for end portions of garments to be joined
together
The invention relates to a connecting element for the end portions of
straps in undergarments, for example the end portion of underbust bands
of brassieres.
Such connecting elements are usually sewn on to both ends of the
underbust band and consist usually of an eyelet or loop tape and its
corresponding eye hook tape.
To manufacture the eyelet tape, the eyelets are first attached to a
continuous base tape in a specified order. This is done by sewing several
so called folding tapes in a partially overlapping arrangement along both
longitudinal sides of the base tape with its sides folded in alongside.
While the folding tapes are sewn onto the base tape, the eyelets are also
attached to the folding tape and base tape along seams which are sewn
parallel to the sides of the base tape. The base tape with the attached
folding tapes is then cut vertically to its sides into individual eyelet
sections.
In known manufacturing processes, the cutting of the individual eyelet
tapes from the continuous tape is performed using a thermo-welding
process, e.g. the ultrasound welding process, which causes the cutting
edge of the base tape and the folding tapes to be joined together. This
process of cutting the eyelet tape from the continuous base tape and
folding tapes is functionally efficient and, therefore, economical. However,
it creates hard and very sharp joints. Since the base tape and the folding
tapes are cut vertically to their sides into individual section,
these joint edges form the side edge of the eyelet tape.
With undergarments, which are worn on the skin such as
brassieres, where the undorbust tapes and straps exert a certain
pressure on the skin, thttre is a danger that the joint edges of
the eyelet tapes, which are also worn on the skin, may cut into
the skin . This leads to an uncomfortable wearing sensation that
may also cause skin irritations.
The same conditions apply to the hook tapes, which are usually
also manufactured using a base tape. The latter is first formed
into a kind of tube by -folding it alongside both sides whereby
the folded in areas are slightly overlapping and are basically of
equal width. The hooks are to be placed in the overlapping area by
way of a seam parallel to the sides of the base tape, which joins
together all layers of the base tape simultaneously.
Again, the base tape with the attached hooks is cut vertically to
its sides into individual hook taps sections. Before cutting the
., individual hook tape sections, the base tape is foled in the
centre longitudinally approximately parallel to its sides,
whereby the layer holding the hooks is positioned on a hook-free
layer.
If the process of separating the individual hook tapes from the
continuous base tape is also performed using the thereto-welding
process, this separating process causes the cutting edges, of the
various layers of the base tape to be joined together. Since the
cutting edges are again cut vertically to the sides of the base
tape, these joint edges also form the front side of the edge of
the hook tape. Here, again, the joint edges of the hook tapes,
when worn directly on the skin cause an uncomfortable wearing
sensation, which may lead to skin irritations.
This invention aims at creating a connecting element for straps of
undergarments, for example underbust bands of brassieres which, while
using the thermo-welding process makes it possible to manufacture hook
and eyelet tapes without sharp joint edges.
The matching hook tape is processed in the following ways the cutoff
welding seams are located within the hook tape between the hook-free
area and the hook-bearing area.
Such an arrangement of cutoff welding seams can be easily obtained if
the cutoff welding seams are positioned between the hook-free section
and the underlying hook-bearing section by turning the seam inside out.
In this way, the cutoff welding seams are placed in the inside of the hook
tape so that the edges that are exposed to the skin consist of the
unwekled material of the hook tape.
The manufacturing of a continuous hook tape can be done by using a
continuous base tape with attached hooks. Before cutting a section of the
base tape within its hook-free end, the base tape is folded parallel to its
sides so that the nooks are covered by a hook-free portion. This section is
then cut off by cutoff welding seams. The two layers are thus joined
together along their cutting edges, thereby allowing the resulting hook
tape to be turned inside-out so that the cutoff welding seams end up in
the inside of the hook tape between the two layers. It is advantageous for
the folding line to be within the hook-free area away from the side of the
fastening seam.
The matching eyelet tape is processed in the following way: the eyelet
tape is given a cover tape to be placed on its eyelet-free area and both
layers are joined together by cutoff welding seams. The cutoff welding
seams are located within the eyelet-free area of the eyelet tape in
between of the latter and the cover tape.
Such an arrangement of cutoff welding seams can be obtained if the
cutoff welding seams are positioned between the eyelet-free section and
the underlying eyelet-bearing section by turning the eyelet tape inside out.
Placing a cover tape over the eyelet-free area of the eyelet tape, not only
allows to turn the sharp pining edges created by the cutoff welding seam
inside the eyelet tape, but also is a means of covering up the fastening
seams of the eyelets which in turn increases the comfort of the eyelet
tape.
In order to position the cutoff welding seam that joins together the cover
tape and the eyelet tape within the area of the base tape, it is best to use
a cover tape that consists of an elastic material, preferably an elastic
fabric.
The manufacturing of a continuous eyelet tape using a base tape with
attached eyelets which have been cut into individual sections through
cutoff welding seams, can be achieved by placing a cover tape before
cutting the eyelet tape into sections over the eyelet-bearing area of the
eyelet-free ends of the base tape. Then, when cutting this section through
cutoff welding seams, the base tape as well as the cover tape will be cut
through while joining the base tape and the cover tape along their cutting
edges. The resulting eyelet tape is then turned inside out in order to bring
the cutoff welding seams between the eyelet-free area of the eyelet tape
and the cover tape.
This process makes it possible to keep up the production of
continuous tapes by turning the cutoff weding seams inside the
eylet tape so that those edges which can be exposed to the skin
are formed by the outside of the cover tape which is not welded.
The matching hook tape is processed in the following way
according to this inventions the hook tape is given a cover tape
to be placed on its hook—free areas and both layers are joined
together with cutoff welding seams. The cutoff welding seams are
located within the hook-free area of the hook tape inbetween of
the latter and the cover tape.
Such an arrangement of cutoff welding seams can be obtained if
the cutoff welding seams are positioned between the cover tape
and the underlying hook-bearing section by turning the hook tape
inside out.
Placing a cover tape over the hook-free area of the cover tape,
not only allows to turn the sharp joining edges, created by the
cutoff welding seam, inside the hook tape, but also is a means of
covering up the fastening seams of the hooks which in turn
increases the comfort of the hook tape.
In order to position the separating welding seam that joins
together the cover tape and the hook tape within the area of the
base tape, it is best to use a cover tape that consists of an
elastic material, preferably an elastic fabric.
the manufacturing of a continuous hook tape using a base tape with
attached hooks which have been cut into individual section through cutoff
welding seams, can be achieved by placing a cover tape before cutting
the hook tape into sections over the hook-bearing area of the hook-free
ends of the base tape. Then, when cutting this section through cutoff
welding seams, the base tape as well as the cover tape will be cut
through while joining the base tape and the cover tape along their cutting
edges. The resulting hook tape is then turned inside out in order to bring
the cutoff welding seams between the hook-free area of the hook tape
and the cover tape.
This process makes it possible to keep up the production of continuous
tapes by turning the separating welding seams inside the hook tape so
that those edges which can be exposed to the skin are formed by the
outside of the cover tape which is not welded.

Figure 1 shows a base tape (1) of a hook tape (2) with
attached hooks (3) in prearranged intervals. These are attached
to the base tape (1) through a fastening seen parallel to the
longitudinal axis of the base tape (2), whereby its longitudinal
axis is at a right angle to the longitudinal axis of the base
tape (2). In the illustration application example, the lateral
sides of the base tape (1) are folded in towards, one another and
are overlapping by a certain measure. The upper side of the base
tape in Fig. 2 may be folded inwards to create a neat edge and
lies above the opposite longer side (6) . The fastening seam (4)
serves at the same time as way to fix the folds of the base tape
(1), which look like a tube-shaped structure with overlapping
hems. A lining may be placed inside the base tape (1).
The shorter side (5) forms, therefore, a hook—bearing area (7)
whereas the longer side (6) forms a hook-free area (8) . The
areas (7) and (8) may be of equal or different sizes.
In Fig. 1, the front end of the base tape (1) along a
predetermined length is to be folded along a fold line formed
preferably by the fastening seam, so that the hook-free area (8)
lies over the hook-bearing area (7). The hooks (3) are,
therefore, covered by the hook-free area (8) within the fold.
With areas (7) and (8) positioned as illustrated above,
successive sections of certain lengths are separated from the
base tape (1) by means of a thermo-welding process, e.g.
ultrasound. The length of the sections determining the length
(or width, in other words) of the hook tape (2) to be
manufactured according to the portion it will be used in when
being worn as part of for example a brassiere.
The cutoff welding tools used for this application are designed
in such a way that they create a cutoff welding seam (10) in the
first section as well as the subsequent second section. The
resulting cutting edges (9) of the hook-bearing area (7) are
thus welded together with the cutting edges (11) of the hook-free
area (8). This creates a hardened and very sharp connecting edge
(12) which are located on the outer edge of the respective area.
During this process, the hooks (3) remain covered by the hook-
free area (8) (Fig.3 and 5).
The process that comas next is turning the tape inside out.
Through the process the respective section is turned in such a
way that allows on the one hand for the hooks (3) of the hook-
free area (8) to be uncovered and on the other hand for the
connecting edge (12) (cutoff welding edge 10) to be turned inside
the finished hook tape (2). Both boundary edges (13,14) of the
hook tape (2) that come in contact with the skin when worn are
thus formed by the material of the base tape (1) (Fig.4).
The hook tape (2) thus manufactured, may be sewn in the usual way
to the strap of a garment, e.g. underbust band of a brassiere.
Hereby, the upper and lower areas of the hook tape (2) that are
sewn to the strap are formed by the boundary edges (13,14).
Fig. 6 shows the base tape (21) an eyelet tape (22) with attached
eyelets (23) in prearranged intervals. As can be seen in Fig. 6 ,
several folding tapes (24) which are positioned along the
longitudinal axis of the base tape have been sewn with fastening
seams (25) to the base tape. These fastening seams (29) are sewn
parallel to the longitudinal axis of the ba*e tape (23). The
fastening seams (25) serve it the same time as a way to fasten
the eyelet (23) to the base tape (21) the longitudinal axis of
which is basically at a right angle to the base tape (21). This
base tape has therefore, an eyelet-bearing area (26) on one of
its side and a a eyelet-free area (27) on its other side.
The base tape (21) is preferable manufactured using a soft
material. It may be formed by a flat tape, the lateral sides of
which, not in the illustration, are folded in towards one another
and are overlapping by a certain measure. The base tape (21)
forms, therefore, a tube-like structure with overlapping hems. A
lining may be placed inside the base tape (1). The folding edges
(28,29) of the base tape (21 ) are both, therefore, front sides of
the eyelet tape (22) (referring to the usage as eyelet tape (22)
for brassieres).
As can be seen in Fig. 6, a cover tape (30) is placed ovtr the
eyelet tape area (26) of the base tape (21) which covers the
eyelets (23).
With the base tape (21) and cover tape (30) positioned as
illustrated above, successive sections of certain lengths are
separated from the base tape (21) by Means of a thermo-welding
process. The length of the sections determines the length (or
width, in otherwords) of the eyelet tape (22) to be manufactured
according to the position it will be used in when being worn
as part of ( for example) a brassiere.
Here, too, the separating welding tools used for this application
is designed in such a way that it creates a cutoff welding seam
(31* 32) in the first section as well as the subsequent second
section. The resulting cutting edges (34) of the eyelet tape (22)
are thus welded together with the cutting edges (35) of the cover
tape (30). This creates a hardened and also very sharp
connecting edge (36) which is located on the outer
edge of the respective area. During this process, the eyelets(23) remain
covered by the welded on cover tape (30).
The process that comes next is turning the tape inside out. Through this
process the respective section is turned in such a way that allows the
cover tape (30) to reach from the eyelet-bearing area (26) to the eyelet-
free area (27) hereby leaving the eyelets (23) uncovered. This permits at
the same time, for the connecting edges (36) (cutoff welding edge 31. 32)
to be turned inside the finished eyelet tape (22). Both boundary edges
(37. 38) of the eyelet tape (22) that come in contact with the skin when
worn, consist thus of the cover tape (30).
The eyelet tape (22) thus manufactured, may be sewn in the usual way to
the strap of a garment, e.g. underbust band of a brassiere. Hereby, the
upper and lower areas of the eyelet tape 22 that are sewn to the strap are
formed by the boundary edges (37,38).
We have so far based ourselves on the assumption that the separation of
individual sections of the hook tape (2) as well as the eyelet tape (22) is
performed at two places through one cutoff welding seam, respectively.
This can be performed by a relatively simple cutoff welding tool. This has
the added advantage of not creating any wastage.
However, the framework of this invention also permits the use of a mold
cutoff welding tool for the separation of the various sections from the hook
tape (2) and/or eyelet tape (22). These tools would make it possible to
weld both separating welding seams simultaneously in the respective
sections.
The hook tape (52) manufactured as described above. can be sewn in the
usual way to the strap of garments, e.g. underbust bands of brassieres.
The upper and lower areas of the hook tape (52) that is sewn to the strap
of the brassiere are formed by the boundary edges (59. 60).
As aforementioned, we start from the fact that the separation of the
individual sections from the hook tape (52) creates a cutoff welding seam
in two sections, respectively. This can be done with a relatively simple
cutoff welding tool and has the added advantage that there is no wastage
of base tape (51).
However, the framework of this invention also permits the use of mold
cutoff welding tool for the separation of the various sections of the hook
tape (52). This enables the user to perform both separating welding
seams of the respective section, simultaneously.
The mold cutoff welding tool used to separate the sections from the base
tape (51) of the hook tape (52) would then only require to be equipped
with 2 straight sonotrodes to be placed at the distance equivalent to the
length of the individual sections.
Once again, it is possible to use a U-shaped sonotrode for the separation
of sections from base tape (51) of the hook tape (52), which enables to
perform both separating welding seams (64, 65) at the same time as the
cross welding seam (69) located between them. In this way, the two
parallel arms of the U-shaped sonotrode make it possible to perform both
cutoff welding seams (64) and (65), and the crossbar located within the
area of one of the two folding edges (59, 60) that links both arms enables
to simultaneously perform the cross welding seam (69) which can be a
normal welding seam (i.e. not a separating welding seam).
This, however, also creates a hardened connecting edge in the area of
the folding edge (59), which may at first be seen as disadvantageous. But
since the process of turning the hook tape (52) inside out makes it
possible to turn this connecting edge between its hook-free area(62) and
the cover tape advantage being that this allows to simultaneously harden the
respective folding edge. If the cross welding seam (69) is
intended to be placed in the end portion of the hook tape (52)
which will not be connected to the strap, then this way of
hardening the respective folding edge will improve the appearance
of the hook tape (52).
