Abstract
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.
Claims17
A printing blanket construction comprising:
- a printing surface layer over a reinforcing fabric ply selected from a weft insertion fabric ply having a denier of at least 1000 and a heavy gauge fabric ply having a gauge of between about 0.020 and 0.040 inches (0.05 to about 0.10 cm), said reinforcing fabric ply having a tensile strength of greater than about 250 lbs/in. (446.5×102) and a residual stretch of less than about 4%;
- wherein no additional reinforcing plies are provided between said reinforcing fabric ply and said printing surface layer.
A printing blanket construction comprising a printing surface layer, a compressible layer, and a reinforcing fabric ply having a tensile strength greater than about 250 lb/in. (446.5×102 g/cm) selected from a weft insertion fabric ply and a heavy gauge fabric ply, wherein said compressible layer is positioned between said printing surface layer and said reinforcing fabric ply, and no additional reinforcing fabric plies are positioned between said reinforcing fabric ply and said print layer.
