Abstract
The invention relates to a roller having a core with a channel formed in the surface which extends across the surface of the core. The channel is tapered in width from a first width adjacent a first edge to a second width adjacent a second opposite edge. A blanket is provided for covering the core with the blanket having a split element adapted to fit around the surface of the core and having first and second abutting edges. The blanket has first and second flanges depending from its abutting edges which flanges, when in abutting relationship, define a cross-sectional area substantially identical to the core channel.
Claims9
Roller apparatus comprising:
- a core;
- means formed on said core for mounting said core with respect to a machine to be served;
- a channel formed in the surface of said core and extending across the surface of said core, said channel being tapered in width from a first width adjacent a first edge to a second width adjacent a second opposite edge;
- a blanket for covering said core, said blanket comprising a split element adapted to fit around the surface of said core and having first and second abutting edges;
- and
- first and second flanges depending from said first and second abutting edges, said first and second flanges, when in abutting relationship, defining a cross-sectional area substantially identical to said channel formed in said surface of said core.
A blanket for use in a roller assembly having a core and a replaceable cover blanket, the blanket comprising:
- a cover means having a first end and a second opposed end;
- a first flange dependent from said first end;
- a second flange dependent from said second end;
- said first flange and said first end cooperating to define a first abutting edge;
- said second flange and said second end cooperating to define a second abutting edge;
- said first and second flanges cooperating to define a locking element when said first and second abutting edges are in abutting engagement;
- and
- said locking element tapering in dimension from a widest dimension at one end to a narrowest dimension at its end opposite said one end.
