ABSTRACT:
A piston rubber with a body of substantially cylindrical exterior shape with one end thereof reinforced with a textile fabric wound into a roll that is arranged generally coaxial with the cylindrical body. The method for making the piston rubber involves winding a length of rubberized fabric around a mandrel and forming a sleeve of desired radial thickness, cutting the sleeve into bands of desired widths, and placing the bands and elastomeric material in a mold and curing the same to define a piston rubber.
