摘要:
A printing blanket is provided which resists gauge loss throughout its useful life when subjected to printing nip pressures. The printing blanket includes a printing surface layer and at least one fabric ply. The fabric ply is treated by impregnation with a 100% solids elastomeric urethane compound which penetrates the air spaces of individual fiber bundles in the fabric ply and fixes the individual fibers in the ply from relative movement so that that the blanket is resistant to permanent deformation. The blanket including the treated fabric ply retains at least 95% of its original gauge throughout its useful life.
摘要:
A printing blanket construction is provided which includes a reinforcing fabric ply comprised of a weft insertion fabric or a heavy gauge fabric, where the reinforcing fabric ply provides all of the necessary tensioning properties to the blanket. The use of the reinforcing fabric ply eliminates the need for additional fabric plies in the blanket construction, and provides high tensile strength, low stretch, and resistance to gauge loss.
摘要:
A composite packing material for use with a printing blanket is provided including a substrate such as fabric, scrim, or film which is coated on at least one surface with a polymeric compound to provide the desired gauge to the printing blanket assembly. The resulting composite packing material has a thickness of about 0.010 to about 0.067 inches (0.25 mm to 1.7 mm) and is substantially volume non-compressible.
