An apparatus for and method of cutting a substantially polymeric belt-defining sleeve to define a plurality of endless power transmission belt constructions are provided by rotating such belt sleeve on a rotating apparatus and cutting a plurality of axially spaced cuts through the sleeve with jet nozzle means disposed at a fixed position and with the jet nozzle means providing high velocity liquid jet means to define an endless power transmission belt construction between associated pairs of cuts.

Apparatus for and method of cutting a belt sleeve

A continuous, spliceless bias fabric in which the angular displacement between the warp and filling yarns is in the approximate range of 90 to 150 degrees is produced by the steps of cutting a tubular, square-woven fabric at a bias angle of 40-50 degrees to provide a continuous length of fabric, optionally drying the fabric, calendering at least one layer of an elastomeric compound to at least one side of the continuous length of fabric, heating the thus-calendered fabric, stretching the fabric in its width direction to provide a warp to filling angle of about 90-150 degrees, and cooling the stretched fabric.
