Abstract
A printing blanket assembly for a blanket cylinder of a rotary printing press includes a dimensionally stable support plate, and a printing blanket fastened to the outside of the support plate. A leading end of the support plate and a trailing end of the support plate are fastened to the blanket cylinder by the provision of an angled or beveled, printing blanket free end. A filler is provided between the beveled end of the support plate and the inner edge of the leading and trailing ends of the printing blanket.
Claims25
A printing blanket unit adapted for use with a printing blanket cylinder of a rotary printing press comprising:
- a dimensionally stable support plate including an exterior surface;
- an angled leading end leg on a leading end of said support plate;
- an angled trailing end leg on a trailing end of said support plate;
- a leading end fold on said support plate between said leading end leg and said exterior surface;
- a trailing end fold on said support plate between said trailing end leg and said exterior surface;
- a printing blanket on said exterior surface and having blanket leading and trailing ends with inside end surfaces situated adjacent said leading and trailing end folds;
- and
- a filler material at said leading and trailing blanket ends between said leading and trailing end folds and said leading and trailing blanket inside end surfaces, said filler material acting as a support element wherein, in an installed position of said printing blanket unit on the printing blanket cylinder, said leading end filler material and said trailing end filler material, which are provided with lateral facing surfaces of a complimentary shape, are adjacent each other at a spacing distance of between 0.2 mm and 0.8 mm.
A printing blanket unit adapted for use with a printing blanket cylinder of a rotary printing press comprising:
- a dimensionally stable support plate including an exterior surface;
- an angled leading end leg on a leading end of said support plate;
- an angled trailing end leg on a trailing end of said support plate;
- a leading end fold on said support plate between said leading end leg and said exterior surface;
- a trailing end fold on said support plate between said trailing end leg and said exterior surface;
- a printing blanket on said exterior surface and having blanket leading and trailing ends with inside end surfaces situated adjacent said leading and trailing end folds;
- and
- a filler material at said leading and trailing blanket ends between said leading and trailing end folds and said leading and trailing blanket inside end surfaces, said filler material acting as a support element, said printing blanket having at least one of said leading and trailing blanket ends of a first, end thickness and a central area located between said leading and trailing ends of a second, central area thickness, said first thickness being greater than said second thickness, whereby an exterior of said printing blanket unit at said end with said first end thickness extends in a radial direction of said printing blanket cylinder past a virtual extension of said central area of said printing blanket unit.
A printing blanket unit adapted for use with a printing blanket cylinder of a rotary printing press comprising:
- a dimensionally stable support plate including an exterior surface;
- an angled leading end leg on a leading end of said support plate;
- an angled trailing end leg on a trailing end of said support plate;
- a leading end fold on said support plate between said leading end leg and said exterior surface;
- a trailing end fold on said support plate between said trailing end leg and said exterior surface;
- a printing blanket on said exterior surface and having blanket leading and trailing ends with inside end surfaces situated adjacent said leading and trailing end folds;
- and
- a filler material at said leading and trailing blanket ends between said leading and trailing end folds and said leading and trailing blanket inside end surfaces, said filler material acting as a support element, said filler material beings secured to said printing blanket prior to the mounting of said printing blanket on said support plate.
