Claims
- 1. A method for manufacturing a printing blanket obtained by assembling a plurality of layers comprising:
forming at least one of said plurality of layers from a thermoplastic elastomer that does not contain any thermal cross-linking agents.
- 2. The method according to claim 1, comprising:
attaching said plurality of layers to one another without the use of solvents.
- 3. The method according to claim 2, comprising:
attaching said plurality of layer by one or more of Corona-type processing, ionization or localized heating.
- 4. A method according to claim l, comprising:
rolling a layer of a thermoplastic material around a sleeve; and fusing together ends of thermoplastic material by heating said ends to their melting temperature.
- 5. The method according to claim 4, comprising:
beveling and then superimposing the ends prior to fusing together said ends.
- 6. The method according to claim 4, comprising:
expanding microspheres incorporated into the thermoplastic material to thereby form a compressible layer.
- 7. The method according to claim 6, wherein the microspheres are expanded when said ends are heated.
- 8. The method according to claim 1, wherein said plurality of layers includes at least one lithographic layer, and said method comprises radiating said lithographic layer to promote cross-linking.
- 9. The method according to claim 8, comprising straightening and grinding the lithographic layer.
- 10. The method according to claim 1, wherein said at least one of said plurality of layers formed from a thermoplastic elastomer is formed by extrusion and without the use of solvents.
- 11. A printing blanket comprising a plurality of layers including at least one thermoplastic elastomer layer that does not contain cross-linking agents.
- 12. A printing blanket according to claim 11, wherein said plurality of layers are fastened to each other by Corona-type processing, ionizing or localized heating.
- 13. A printing blanket according to claim 11, wherein a lithographic layer of the printing blanket is cross-linked by radiation.
- 14. A printing blanket according to claim 13, wherein the lithographic layer is straightened and sanded.
- 15. A printing blanket according to claim 11, shaped as a sleeve and including a layer of thermoplastic material whose ends are fused together following heating of said ends to the melting temperature of the material.
- 16. A printing blanket according to claim 15, comprising a tubular compressible layer having expanded microspheres incorporated therein, said microspheres having been expanded upon heating of said ends.
- 17. A printing blanket according to claim 11, wherein a layer on a back side of the printing blanket is formed from a polymer material.
- 18. A printing blanket according to claim 17, wherein said layer on the back side is straightened.
- 19. A printing blanket according to claim 11, further comprising a beam, thread or fabric grid.
- 20. A printing blanket according to claim 11, having an external layer with a surface comprising incrustations of particles.
