STRINGER TAPE FOR SLIDING CLASP FASTENERS This invention relates to sliding clasp fasteners, and more particularly to an improved stringer tape for such fasteners.
Generally, a sliding clasp fastener comprises a pair of stringer tapes having a web portion and a laterally projecting flange or bead formed at one longitudinal edge of each tape and a row of interlocking fastener elements secured to the flanges and extending longitudinally of the tape.
When mounting the interlocking fastener elements along the flanged or beaded longitudinal edge of each stringer tape, it is desirable to make said edge of the stringer tape moderately stiff and inextensible so as to facilitate the mounting operation and to ensure that the mounted fastener elements be held in regularly spaced apart and aligned relation and free from deformation or misalignment which would be caused, as for example when the tape becomes shrunk after washing or due to heat treatment.
It has been the conventional practice to form the flange from a stranded cord or from a plurality of intertwined twisted threads. This obviously results in too soft and elastic a flange to retain the fastener elements stably in position and securely in uniformly spacedapart relation on the fastener. Such objectionably elastic cord may be stiffened temporarily by using a suitable stiffening compound or glue, but it is difficult to infiltrate the stiffening compound or glue into the interstices between individual fibres constituting the cord or threads, and therefore the cord soon restores its resiliency after the washing and heat treatment to which finished slide fasteners are usually subjected to.
It is therefore the primary object of the invention to provide a tape stringer for sliding clasp fasteners, the tape having at one longitudinal edge thereof a laterally extending flange with suitable stiffness and inextensibility.
Another object of the invention is to provide a tape stringer of the type mentioned which is simple in construction and may be produced easily and economically.
According to the invention, the tape stringer comprises a tape web portion and a stiffened, inextensible, elongated cord formed separately from the tape web and consisting of a plurality of textile fibres bonded together by an adhesive compound, said cord being secured to one longitudinal edge of the tape web and forming therealong a laterally projecting flange or bead.
According to a further feature of the invention, the flange may have a core of non-elastic material to further impart an inextensible characteristic to the element-carrying tape edge.
The above and other objects and advantages of the invention will become apparent from consideration of 60 the accompanying drawings and annexed specification illustrating and describing preferred embodiments of the invention.
In the drawings:
FIG. 1 is a perspective view of a fragmentary portion of a slide fastener stringer tape provided with a beaded edge portion at one longitudinal edge thereof according to the invention;
FIGS. 2a to 20 are detailed perspective views showing different arrangements of sliver fibres constituting the bead-forming cord; and
FIG. 3 is view similar to FIGS. 2a through 2c, but showing a modified bead construction.
Referring to the drawings, the improved stringer tape I construction, which is generally indicated at 10, comprises a tape web portion 11 and a laterally projecting flanged or beaded portion 12. The flanged portion 12 consists of a plurality of textile fibres 13 such as cotton sliver which are bonded together by a suitable adhesive compound 14 to provide an elongated unitary cord of inextensible property. The bead-forming cord 12 is formed separately from the tape web portion 11 and secured to one longitudinal edge of the tape by weaving or knitting operation.
In FIGS. 1 to 3, the bead or cord 12 is shown as having a circular cross-section, however, it may be provided in different sectional forms, if desired. Thickness of the cord 12 may be determined by the size of the fastener elements to be secured thereto. With fasteners of larger sizes, a plurality of cords of the same thickness may be used as particularly shown in FIG. 20. FIGS. 2a and 2b show on enlarged scale different beadforming cord construction. It will be noted that no twist is imparted to the sliver fibres 13 in the example shown in FIG. 2b.
The degree of stiffness of the bead desired for a particular field of application of the slide fastener may be controlled by the choice of an adhesive compound or glue for bonding the sliver fibers together according to the invention.
The cord 12 thus obtained presents suitable resiliency and smooth surface texture which will permit the fastener elements to be firmly anchored to and aligned regularly along the beaded marginal edge of the stringer tape.
In order to further ensure inextensibility of the flanged or element-carrying tape edge portion, the cord 12 may incorporate a non-elastic core material 15 preferably in the nature of a cord, string, thread, filament or the like, as shown in FIG. 3.
By application of the invention to slide fasteners, it is made possible to secure the fastener elements stably into position on the edge portion of the stringer tape and at the same time to maintain the mounted elements in uniformly spaced apart relation, with the results that the elements are free from displacement or deformation which would often be encountered when or after the finished fastener is washed or heat-treated.
Although there have been described preferred embodiments of the invention, it will be appreciated that they are only illustrative and the scope of the invention is best defined in the appended claims.
What is claimed is:
l. A stringer tape for sliding clasp fasteners, comprising a tape web portion and a cord formed separately from the tape web and secured to a longitudinal edge thereof to form therealong a flange for mounting fastener elements, said cord having a central, longitudinally extending reinforcing core and a multiplicity of longitudinally extending fibers bonded together and to said core by an adhesive that is separate from said fibers and core and occupies intersticial spaces thereamong.
2. A stringer tape as defined in claim 1, wherein said fibers are cotton fibers.
3. A stringer tape as defined in claim I wherein said cord has a circular cross-section.
Claims (3)
1. A STRINGER TAPE FOR SLIDING CLASP FASTENERS, COMPRISING A TAPE WEB PORTION AND A CORD FORMED SEPARATELY FROM THE TAPE WEB AND SECURED TO A LONGITUDINAL EDGE THEREOF TO FORM THEREALONG A FLANGE FOR MOUNTING FASTENER ELEMENTS, SAID CORD HAVING A CENTRAL, LONGITUDINALLY EXTENDING REINFORCING CORE AND A MULTIPLICITY OF LONGITUDINALLY EXTENDING FIBERS BONDED TOGETHER
2. A stringer tape as defined in claim 1, wherein said fibers are cotton fibers.
3. A stringer tape as defined in claim 1 wherein said cord has a circular cross-section.
