Abstract

Abstract An endless belt is provided which is suitable for being rotated during use in various manufacturing and material handling operations and the like and is characterized by a construction having an increased surface and edge wear potential. The belt is a woven endless fabric strip of predetermined width and length which defines opposing outside and inside surfaces and lefthand and righthand edges and is of a spliceless and Mobius strip construction having a 180° turn in the surfaces thereof for providing in effect one spliceless continuous surface and one spliceless continuous edge of twice the predetermined length of the belt during rotation thereof by the inside surface reversing and becoming the outside surface and the lefthand edge reversing and becoming the righthand edge during each complete revolution of the belt. The belt has an interwoven warp and filling and the warp, preferably, is in the form of at least one continuous warp yarn wrapped generally in the form of a helix of the predetermined length and width of the belt and having a 180° turn at a given location along the length thereof.
