Description
This invention relates to composite elastic bands of prefabricated
form primarily for subsequent attachment to a garment (e.g., for
incorporation in a garment during the latter's manufacture) as a
waist band or other constricting or supporting band.
Such composite elastic bands and garments are the subject of many
prior Patent Specifications in each of which the composite band
comprises at least one ribbon of elastic (e.g., rubber, natural or
synthetic) to which other strip material is secured, the latter
material being knitted or woven fabric.
An object of the invention is to provide composite elastic bands
and garments in improved manner.
The invention provides a composite elastic band capable of being
stretched elastically from a relaxed condition and particularly a
band in or for a grament, comprising a core of ribbon elastic
(e.g., rubber, natural or synthetic) to which stretch-limiting,
flexible, non-woven strip material is secured in such manner that
in the relaxed condition of the band the strip material is
compressed in the lengthwise direction of the band by the core and
the extent of stretching of the composite elastic band is limited
by the strip material. One strip material may be bonded fibre strip
material, for example of the type sometimes known as "interlining"
or a plastics strip material (which may be perforated).
Conveniently the securing of the core to the strip is by adhesive.
Alternatively, or in addition, the core may be secured to the strip
material by stitching. Conveniently also there are at least two
ribbons of elastic disposed edge to edge with a gap between them,
and the strip material is sufficiently wide to be secured to both
of the elastic ribbons. The strip material may be provided to
extend over one side only of the elastic ribbon, or it may be
provided to extend over both sides of the elastic ribbon. In the
latter instance the strip material may be provided in a single
length of sufficient width to extend over one side of the elastic
ribbon and be folded over outer edges of the elastic ribbon from
one side to the other side thereof, with the free edges either
spaced apart, or closely adjacent, or mutually overlapping.
Alternatively there may be two strips of the said material between
which the elastic ribbon is sandwiched and which are not folded
over the outer edges of the elastic ribbon. The composite elastic
band thus formed may be subsequently incorporated in a cover formed
by a wide strip of knitted or woven fabric which extends over one
side of the band and is folded over the outer edges either of the
elastic ribbon only, or also of the strip material, from one side
to the other thereof, with the free edges of the cover either
spaced apart, or closely adjacent, or mutually overlapping.
Alternatively the cover of knitted or woven fabric may be provided
by a wide marginal part of a garment folded over the outer edges of
the elastic ribbon and strip material. In each instance the
composite band is adapted to be secured to a garment by at least
one longitudinal row of stitches or by spaced longitudinally
extending rows of stitches. The stitches extend through the
attached elastic ribbon and strip material and through the garment.
Where a cover of knitted or woven fabric is provided other than by
the marginal edge of the garment, the stitches also extend through
the cover. Where a cover is provided by the marginal edge of the
garment the stitches need not necessarily extend through the strip
material, or through the elastic ribbon. For example the band may
be enclosed in a tunnel formed by the marginal fabric of the
garment.
The manner of applying the adhesive may be by transverse strips
thereof closely spaced longitudinally of the band, or by
longitudinal strips of adhesive closely spaced transversely of the
band or by spaced areas of adhesive.
A specific embodiment of the invention will be hereinafter
particularly described by way of example with reference to the
accompanying drawings in which:
FIG. 1 is a diagrammatic cross sectional view of a composite
elastic band according to the invention.

FIG. 12 which is a modified form of the construction of FIG. 5.
FIG. 13 which is a further modified form of the construction of

FIG. 14 which is a still further modified form of the construction
of FIG. 5.
Referring to FIG. 1 the composite elastic band in this Figure
comprises two ribbons 1, 2 of elastic, which may be of rubber,
natural or synthetic, disposed edge to edge with a space 3 between
them, and two strips 4, 5 of stretch-limiting, flexible, non-woven
material between which strips the elastic ribbons 1, 2 are
sandwiched. In all constructions according to this invention the
stretch-limiting strips are (or strip is) of flexible, non-woven,
fabric consisting of a web or mat of fibres held together with a
bonding material. The strips 4, 5 are of sufficient width to extend
over the elastic ribbons 1, 2, one on each side thereof, and the
strips 4, 5 and the elastic ribbons 1, 2 are stuck together by
adhesive. The adhesive may be applied in continuous or
discontinuous transverse stripes or plain or fancy patterns thereof
closely or otherwise spaced longitudinally of the band, and since
the strips 4, 5 are adhered to the elastic ribbons 1, 2 while the
latter are stretched longitudinally, the band including the strips
4, 5 become longitudinally puckered or otherwise compressed in the
relaxed condition. Alternatively the adhesive may be applied in
continuous or discontinuous longitudinally extending stripes or
plain or fancy patterns whereby the band is longitudinally striped
or otherwise patterned, and since the strips 4, 5 are adhered to
the elastic ribbons 1, 2 while the latter are stretched, the strips
4, 5 become puckered or compressed longitudinally in the relaxed
condition of the band. Alternatively or in addition to the strips
4, 5 being stuck to the ribbons 1, 2 they may be secured by spaced
lines of stitches S.
In the modification of FIG. 2 there is only one stretch-limiting
strip 6, and this is adhered to one side of the elastic ribbons 1,
2 in any of the arrangements described for FIG. 1. In addition
there is a textile cover strip 7 of knitted interlock or other
textile material. This cover strip 7 is of sufficient width to
cover the opposite face of the elastic ribbons 1, 2 and to have
margins folded over the opposite outer edges of the elastic ribbons
1, 2 and the strip 6 to form a sheath, with margins overlying
margins of the strip 6 there being a wide gap 8 between the free
edges of the cover strip 7 whereat part of the strip 6 is exposed,
and the cover strip being secured in position by adhesive in any of
the arrangements hereinbefore described and/or by stitches S.
FIG. 3 shows a further modification in which the elastic ribbons 1,
2 and the stretch-limiting strips 4, 5 are as in FIG. 1 and are
disposed in a cover strip 7 of knitted interlock or other textile
material. The cover strip 7 extends over one face of one of the
strips for example, the strip 4 and it is of sufficient width to
have margins folded over the opposite edges of the strips 4, 5 and
the elastic ribbons 1, 2 from said one face to the other thereof
with margins overlying margins margins of the other strip, such as
the strip 5. There is a wide gap 8 between the free edges of the
cover 7 whereat the strip 5 is exposed, and the cover strip 7 is
secured in position by adhesive in any of the arrangements herein
described and/or by stitches S.
FIG. 4 illustrates a similar construction to FIG. 2 but shows that
there may be only one elastic ribbon 10 of a width which may be
substantially equal to the combined widths of the elastic ribbons
1, 2, but which may be of any other desired width.
FIG. 5 shows that a cover strip 11 may be formed of a marginal edge
of a garment 12 which provides a layer 11a covering the outer face
of the stretch-limiting strip 4, a layer 11b which covers the outer
face of the stretch-limiting strip 5, and a marginal part 11c which
is folded around the lower edge of the elastic ribbon 2 and strips
4, 5 is secured by stitches S.
FIG. 6 shows that a single stretch-limiting strip 13 may be of
sufficient width to be folded over the opposite edges of the
elastic ribbons 1, 2 and to be adhered to the elastic ribbons on
both faces thereof in any of the arrangements hereinbefore
described. In this modification there is a gap 14 between the edges
of the strip 13.
The modification of FIG. 7 is similar to that of FIG. 6 except that
the marginal edges of a single stretch-limiting strip 16 overlap
each other as at 17 and are secured together.
FIG. 8 shows a similar arrangement to FIG. 5 except that there are
more than two, and in this instance four, elastic ribbons 18 to
21.
in a modification, FIG. 9, the cover 7 of knitted or woven fabric
extends over one side of the ribbons 1, 2, and the marginal edges
of the knitted or woven fabric are folded over outer edges of the
elastic ribbon 1, 2 from one face to the other thereof. Said
marginal edges are also sandwiched between the elastic ribbons 1, 2
on the one hand and the stretch-limiting strip 6 on the other
hand.
A further modification, FIG. 10, is similar to FIG. 9 except that
the marginal edges of the cover are sandwiched between a single
wide elastic ribbon 10 and the stretch-limiting strip 6.
FIG. 11 illustrates an arrangement in which two elastic ribbons 1,
2 are sandwiched between stretch-limiting strips 4, 5 and a cover
strip 7 of knitted or woven fabric extends over both faces thereof
with its marginal edges overlapping.
In a modification of FIG. 5, shown in FIG. 12, the cover strip 11
is not folded to form a hem at its lower edge but the edge 11d is
made neat, that is, finished off, with blanket stitching 11e.
In another modification of FIG. 5, shown in FIG. 13, the edge 11d
of the cover strip 11 is hemmed as at 11f without being folded
around the elastic ribbon 2 and strips 4, 5.
In a further modification of FIG. 5, shown in FIG. 14, the edge 11d
of the cover strip 11 is left as a raw edge to which is attached a
garment lining 22 for example by overlock stitching 11g.
In all the constructions hereinbefore particularly described and
illustrated the stretch-limiting strip functions as a carrier or
backing for the elastic ribbon, the resultant composite band being
readily handled and incorporated in a garment.
An important advantage of the use of the bonded fibre or other
stretch-limiting strip is that it is substantially unstretchable
and when adhered to the elastic ribbon has a further function of
limiting the extend to which the composite band can be
stretched.
In the instance of two or more elastic ribbons they are kept by the
stretch-limiting strip in correct alignment and in balanced
tension.
The stretch-limiting strip also provides a desired degree of
stiffening and balancing across the width of the band. The adhesive
is at all times completely covered which avoids the possibility of
parts undesirably sticking during layering, packaging and storing.
Any chalk (which may be used as a lubricant) on the elastic is held
within the composite band by the bonded fibre strip.
Other advantages are that at least the construction shown in FIG. 1
should be less expensive that other known forms of composite
elastic band and also less expensive than woven elastic, e.g., for
swimwear. In the instance of FIG. 3, stretching of the band should
not change its width so that such a band should provide a minimum
of bulk in a garment such as at the waist band.
It is intended that the constructions hereinbefore particularly
described and illustrated shall be prefabricated and subsequently
attached to a garment by rows of stitches indicated at S in, for
example, FIGS. 3, 5 and 8.
For example the composite band may be introduced while folding a
marginal edge of the garment over it and parts being secured
together by one row or a plurality of rows of stitches. The ends of
the band may be then stitched together so that the band forms a
continuous ring. Alternatively, the ends of a suitable length of
the band may first be stitched together to form a continuous ring,
and the latter introduced into the garment as already
described.
In any arrangement according to the invention there may be one, two
or more of the elastic ribbons.
