摘要:
The invention relates to a printing blanket assembly for a blanket cylinder of a rotary printing press. The printing blanket assembly comprises a dimensionally stable support plate (02,18) with two ends, one of which is the forward end and the other one is the trailing end with respect to the rotation of the blanket cylinder, these ends being fastened to the blanket cylinder with folded, printing-blanket free limbs (21, 22). The assembly further comprises a printing blanket (03, 19), fastened to the outside of the support plate (02, 18) and having a forward end (12, 31) and a trailing end (11, 32). Said printing blanket assembly allows for perfect printing also in the area of a gap between the limbs (21, 22) and can be produced in a simple manner. For this purpose, both ends (11, 12; 31, 32) of the printing blanket (03, 19) project beyond the bevelled edge (08, 09; 27, 28) of the pertaining limbs (04, 06; 21, 22) of the support plate (02, 18) and one support element (13, 14; 34, 36) for supporting said projection is disposed between the bevelled edge (08, 09; 27, 28) and the inside of the printing blanket (03, 19).
摘要:
Rubber blanket sleeve for a channel-free rubber blanket cylinder of an offset printing machine and process of producing rubber blanket sleeve. The rubber blanket sleeve includes an inner, dimensionally stable support sleeve arranged as a supporting layer, and a microporous compressible elastomer layer having a compressibility within a range between about 7% and 15% with a load of 100 N/cm2. The elastomer layer includes a rubber matrix having a tensile stress of greater than about 2.2 N/mm2 and less than about 15 N/mm2 with 100% elongation. An outer covering rubber layer is arranged as a printing layer. All of the layers are composed of seamless, cylindrical bodies and are coupled to one another. The process includes arranging an inner, dimensionally stable support sleeve as a supporting layer, and positioning a microporous compressible elastomer layer having a compressibility within a range between about 7% and 15% with a load of 100 N/cm2 over the support sleeve. The elastomer layer includes a rubber matrix having a tensile stress of greater than about 2.2 N/mm2 and less than about 15 N/mm2 with 100% elongation. The process further includes arranging an outer covering rubber layer as a printing layer, such that all of the layers are composed of seamless, cylindrical bodies and are coupled to one another.
