Abstract: A pneumatic tubeless tire is produced in such a way that the tire cord fabric (also known as the tire carcass fabric or ply fabric) has the ends thereof secured during tire building so that separation of the cord fabric ends, and a resulting blemish, does not occur. The carcass fabric is wrapped around a rubber inner lining body with turned up portions of the carcass fabric at a pair of beads on opposite sides of the body, during tire construction. The free ends of the carcass fabric are butted together around the body, to provide a butt seam. The free ends are held together in substantial butting position by placing an open mesh warp knit splicer fabric highly extensible in both the machine and cross-machine directions over the butt seam and affixing the splicer fabric in place using adhesive or the like. Rubber tack may be applied over the splicer fabric. The open mesh fabric appears to have no machine direction or cross-machine direction yarns, but only bias yarns.

The fabric according to the present invention has good water-permeability and water-diffusibility and, therefore, is suitable for sportswear.

Abstract: A plurality of elongate warp-knit webs are connected side by side by water-soluble connecting threads along their longitudinal edges. The warp-knit webs are arranged in connected pairs each having a pair of opposed marginal edge portions for supporting a pair of rows of coupling elements, respectively. The connecting thread extends between and interconnects inner wales adjacent to the outermost wales in the opposed marginal edge portions in each pair of the warp-knit webs. The outermost wale is formed solely with a single thread and is shifted into contact with the inner wale, thereby providing a single widened wale along a longitudinal edge of the web. Between the opposed longitudinal marginal edges of the paired webs, there is a gap or clearance that is small enough to make a slide fastener sightly and resistant to being split open under accidental conditions.

When the fastener is zipped to open or close the sheet, the tightening device is to be operated beforehand to loosen the sheet. By the provision of this tightening device, the operation of the fastener can be freely functioned as a zipper, and flapping of the sheet can be prevented by the sheet-tightening action of the tightening device.

This feature is particularly significant when the fabric is fashioned into tubular form, whether straight or bifurcated. The structure of the fabric is such that a desired degree of rigidity is obtained with a thinner fabric than has hitherto been the case.
