Automatic Braiding Company (Nottingham) Limited from which priority is claimed 12 Claims, 14 Drawing Figures PATENIEB RWE aeesazs SHEET 3 M3 COMPOSITE ELASTIC IBANDS AND GARMENTS INCORPORATING SUCH BANDS This is a continuation of application Ser. No. 96,529, filed Dec. 9, 1970, now abandoned.

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 latters 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, nonwoven 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). Con-- veniently 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 andbe 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 gar ment 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 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:

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 sand-,

wiched. 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 rib- 3 bons 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 l, 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 l, 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 l, 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 strip6 is exposed, and the cover strip being'secured in position by adhesivein 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 ofa 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 110 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 stretchlimiting strip 16 overlap each other as at 17 and are secured together.

FIG. 8 shows a similar arrangement to FIG. 5 except A further modification, FIG. 10, is similar to FIG. 9

except that the marginal edges of the cover are san'dv wiched between a single wide elastic ribbon l0 and the stretch-limiting strip 6.

FIG. 11 illustrates an arrangement in which two elastic ribbons 1, 2 are sandwiched between

stretchlimiting 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 lle. In another modification of FIG. 5, shown in FIG. 13,

the edge 11d of the cover strip 11 is hemmed as at 11f fibre or other stretch-limiting strip is that it is substaningduring layering, packaging and storing. Any chalk (which may be used as alubricant) 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 thatthe constructionshereinbefore particularly described and illustrated shall be prefabricated and'subseque'ntly attached to a garment by rows of stitchesindicated at S in, for example, FIGS. 3, 5 and 8.

For example the composite band maybe 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 continu ous 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.
