IMPROVEMENTS IN TOOTHED BELTS

摘要

Toothed belt (2) made of elastomeric material or the like, which comprises a plurality to teeth (8), alternated with spaces (9), covered with at least one layer (10) of textile material. The elastomeric material forming the top of at least one tooth and the relative covering layer are shaped to define at least a depression (11) limited by two lateral protuberances. The seam joining the fabric end portions is situated along the depression so that no rubbing can take place between the seam and a surface external to the belt. Preferably, the depression bottom is limited by a curvilinear length (13) and the ratio between the thickness "s" of the covering layer and the bending radius "r" of the bottom ranges between 0.1 and 10.
