  • Patent number: 6959644
    Abstract: A method for securing a mounting bar at one end of a blanket including a lithographic layer and a support layer and, interposed between those two layers, at least one reinforcing woven layer. The end of the blanket, where the bar is to be fixed, is stripped until the main or single reinforcement of the blanket is exposed and the bar is fixed at least on the stripped part on the end of the blanket. The invention is applicable to printing machines.

  • Patent number: 5456171
    Abstract: A belt-shaped element for printing textiles. The belt is a sandwich structure shaped to conform around two textile printing machine cylinders, and operative to move fabric articles thereon past printing stations with minimal registration error. An exemplary belt has at least one outer elastomer layer, or "working layer," and an inner "cylinder" layer that is innermost against the printing machine cylinders. An exemplary cylinder layer comprises a sheet of fibers oriented longitudinally and having a rigidity of 10.sup.6 -10.sup.7 megapascals in the longitudinal direction. Other exemplary belts comprise an intermediate layer between the outer elastomer and inner fiber sheet layers. An exemplary intermediate layer comprises a layer of transverse fibers.
