Abstract
In a belt there is provided an end region facilitating splicing or repair of the belt. The region includes a reinforcing core extending in the lengthwise direction of the belt and a separator layer. The separator layer is relatively non-adherent to the reinforcing core and facilitates removal of at least one of the outer cover layers for splicing or repair of the belt. The region is provided during manufacture of the belt.
Claims25
In an elastomeric belt having a reinforcing core extending in the lengthwise direction of the belt, and a pair of outer cover layers of elastomeric material,
- an end region facilitating splicing or repair of the belt,
- an end surface on said end region,
- a separator layer in said end region interposed between said core and at least one of said outer cover layers for facilitating removal of one of said cover layers from said core during splicing or repair, said separator layer terminating at a position spaced from said end surface to protect said core against entry of foreign matter.
A method of manufacture of an elastomeric belt including an end region facilitating splicing or repair of said belt, said method comprising the steps of:
- (a) forming a reinforcing core,
- (b) covering at least a portion of said core in said end region with a separator layer,
- (c) covering said core and said separator layer with a pair of outer cover layers of elastomeric material which extend beyond said separator layer in the lengthwise direction of the belt to form an end surface of said belt.
A method of splicing belts of the type having an end region including a reinforcing core interposed between a pair of outer cover layers and a separator layer overlying at least a part of said core, the method including the steps of:
- (a) cutting through at least one of said outer cover layers in said end region,
- (b) peeling off said separator layer and said cover layer to expose the reinforcing core,
- (c) overlapping the exposed ends of said core,
- (d) providing uncured elastomeric material to fill the spaces between the exposed overlapped ends of said core and to form a flat and continuous spliced region surface, and
- (e) applying heat and pressure to said uncured elastomeric material.
