Abstract
A paint roller having a tubular core formed of thermoplastic material. The thermoplastic material being in the form of a multiplicity of spirally wound plies. The multiplicity of plies comprising an outer ply surrounding and in continuous contact with an inner ply. The plies are in general parallelism with one another and fused to one another in the absence of adhesive. A fabric cover overlies the core and is heat fused to the underlying core in the absence of adhesive.
Claims4
A paint roller, said paint roller including
- a tubular core,
- said core being formed of thermoplastic material,
- said core further being formed from a multiplicity of spirally wound plies of said thermoplastic material,
- said multiplicity of plies comprising an outer ply surrounding and in continuous contact with an inner ply,
- each of said plies being layed up in general parallelism with one another,
- said plies being fused to one another in the absence of adhesive,
- said core being of a generally unitary construction having a radially innermost portion oriented in a given direction and a radially outermost portion which overlaps the innermost portion and is oriented in generally the same direction,
- said core being composed of polypropylene, and
- a fabric cover overlying said multi-ply core,
- said fabric cover being heat fused to the underlying multi-ply core in the absence of adhesive.
