Abstract
A reinforcing fabric, for power transmission belts, hoses and the like is formed by upper and lower sets of non-interlaced, crossing bias yarns, set at a wide angle, such as 120.degree. during the construction of the fabric. At selected crossing points, bias yarns from the respective sets are engaged by loop portions of longitudinally extending lines of stitching. The yarns are pre-impregnated with an elastomeric or other agent to increase stiffness, prior to the construction of the fabric. The bias yarns may be designed with significantly greater flexibility than with conventional fabrics and with lower twist and higher density than conventional. Many of the labor-intensive operations of conventional reinforcing fabrics are eliminated when using the new fabric. In one version, the longitudinal stitching, securing one set of bias yarns to the other, is melted during the curing process, when the reinforcing material is incorporated into the article to be reinforced.
