Abstract
A compressible printing sleeve carrier for use in offset lithography which is formed from a composite fiber-reinforced compressible polymer is provided. The printing sleeve carrier is formed by coating reinforcing filaments with a compressible polymer and winding the filaments around a mandrel to form a hollow cylindrical base, where the first portion of the base adjacent the inner surface contains the wound reinforcing filaments coated with the compressible polymer and the second portion of the base adjacent the outer surface contains the compressible polymer.
Claims17
A compressible printing sleeve carrier comprising:
- a hollow cylindrical base having inner and outer surfaces, a first portion of said hollow cylindrical base adjacent said inner surface thereof comprising a first non-compressible layer of continuous reinforcing filaments coated with a substantially void-free polymer and wound around said hollow cylindrical base and a second compressible layer on said first layer comprising continuous reinforcing filaments coated with a volume compressible polymer and wound around said hollow cylindrical base.
A method of making a compressible printing sleeve carrier comprising:
- providing a mandrel;
- providing a source of continuous reinforcing filaments;
- coating said continuous filaments with a volume compressible polymer;
- winding said coated continuous reinforcing filaments under tension around said mandrel in a single pass to form a carrier comprising a hollow cylindrical base comprising a single layer of said volume compressible polymer and having inner and outer surfaces;
- wherein said volume compressible polymer flows above said filaments such that a first portion of said hollow cylindrical base adjacent said inner surface thereof contains said continuous reinforcing filaments coated with said volume compressible polymer and a second portion of said hollow cylindrical base adjacent said outer surface thereof comprises said volume compressible polymer which is free of reinforcing filaments.
A method of making a compressible printing sleeve carrier comprising:
- providing a mandrel;
- providing a source of continuous reinforcing filaments;
- coating said continuous reinforcing filaments with a substantially void-free polymer and winding the coated reinforcing filaments around said mandrel to form a first non-compressible layer;
- coating the continuous reinforcing filaments with a volume compressible polymer and winding the coated reinforcing filaments around said mandrel to form a second, compressible layer on said first layer.
