Abstract
An endless loop article of manufacture comprises a core consisting essentially of at least one skein and a protective covering consisting essentially of hose fabric loosely enclosing said core, and a warp threading and a weft threading which latter comprises at least one monofilament thread extending transverse to the central loop axis, and preferably a monofilament and a multifilament thread arranged to run side by side. The protective covering comprises an endless toroidal part and an internal annular selvedge flange extending radially inwardly from the latter. A strap can be formed from such article of manufacture so deformed that opposite segments of the internal selvedge flange are brought into contact and sewn together, e.g. with an auxiliary warp thread, or by superimposing a protective layer to which the segments are sewn. The protective covering of the article can further comprise an external circumferential selvedge flange projecting radially outwardly from the toroidal part. From this kind of straps a mat can be formed by conventional methods.
