FORCE TRANSMISSION BELT
First Claim
1. A power transmission belt in the form of an endless belt formed of at least one belt material with a lengthwise belt direction and a belt width extending transversely thereof, comprising a belt backing, a tension member zone with a plurality of tension members arranged spacedly adjacent one another and parallel to one another over the belt width, and a power transmission zone adjoining the tension member zone, wherein the tension members are formed by at least two narrow strips of a prestretched plastics material, which are arranged adjacent one another over the belt width and are spaced from one another by belt material, wherein the two narrow strips forming the tension members are formed by spiral winding of a strip over the belt width.

Abstract
The invention relates to a force transmission belt, formed of at least one belt material (2) having a belt longitudinal direction and having a belt width extending transversely to the belt longitudinal direction, containing a belt back (1), a tension-bearing element zone (3) having a plurality of tension-bearing elements arranged adjacent to each other over the belt width at a distance and parallel to each other, and a force transmission zone (6) adjoining the tension-bearing element zone (3). Said force transmission belt can be formed simply, economically, and with improved running properties in that the tension-bearing elements are formed by at least two narrow strips (4) of a pre-stretched plastic material, which strips are arranged adjacent to each other over the belt width and are spaced apart from each other by belt material (2).
