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 reinforcing fabric plies in the blanket construction, and provides high tensile strength, low stretch, and resistance to gauge loss.
Claims19
A printing blanket construction comprising:
- a printing surface layer on a single 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%.
A printing blanket construction comprising a printing surface layer, a compressible layer, and a single 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.
