Abstract
A method of joining a woven fabric on a power transmission belt and transferring an identifying mark thereon by providing a discrete sheet element with an identifying mark thereon, providing a woven sheet having spaced ends, abutting the spaced ends of the woven sheet to each other, placing the discrete sheet element over the abutted ends of the woven sheet, adhering the discrete sheet element to the abutted ends of the woven sheet, and combining the woven sheet with the discrete sheet element adhered thereto with at least one other component to produce an unvulcanized power transmission belt/belt sleeve, wherein the surface of the power transmission belt defined by the woven sheet is characterized by the absence of any recessed or stepped portions.
Claims20
A method of applying an identifying mark onto a power transmission belt/belt sleeve, said method comprising the steps of:
- providing a discrete sheet element with an identifying mark thereon;
- providing a woven sheet having spaced ends;
- abutting the spaced ends of the woven sheet to each other;
- placing the discrete sheet element over the abutted ends of the woven sheet;
- adhering the discrete sheet element to the abutted ends of the woven sheet;
- and
- combining the woven sheet with the discrete sheet element adhered thereto with at least one other component to produce an unvulcanized power transmission belt/belt sleeve, with the identifying mark displayed on an exposed surface of the power transmission belt/belt sleeve.
A method of manufacturing a power transmission belt and placing an identifying mark onto the power transmission belt, said method comprising the steps of:
- providing a discrete sheet element with an identifying mark thereon;
- abutting spaced ends of a woven sheet to define a butt joint;
- placing the discrete sheet element over the abutted ends of the woven sheet and butt joint to define a primary laminate;
- heating the primary laminate while pressing the abutted ends of the woven sheet and discrete sheet element, one against the other;
- combining the woven sheet with the discrete sheet element thereon with a plurality of belt layers, wherein the plurality of belt layers defines a secondary laminate on a forming drum so that the woven sheet with the discrete sheet element defines one of the innermost and outermost layers on the secondary laminate, and wherein the secondary laminate with the woven sheet having the discrete sheet element thereon defines an unvulcanized belt sleeve with the identifying mark displayed on an exposed surface of the unvulcanized belt sleeve;
- and
- vulcanizing the unvulcanized belt sleeve.
