Patent number: 6705225Abstract: A tubular printing blanket including a tubular print layer, a tubular isotropic plastic reinforcing layer underneath the print layer, a compressible layer underneath the reinforcing layer, and a sleeve for supporting, directly or indirectly, the compressible layer. es axial stability due to its isotropic nature and the plastic material. Also disclosed is a method for manufacturing a tubular printing blanket including forming a tubular reinforcing layer and sliding the tubular reinforcing layer over a compressible layer. Furthermore, a device for manufacturing a tubular printing blanket is also provided. A first build cylinder has an outer diameter. A mandrel cap can be attached to one end of the build cylinder, the mandrel cap having an outer diameter larger than the build cylinder outer diameter.Type: GrantFiled: February 15, 2002Date of Patent: March 16, 2004Assignee: Heidelberger Druckmaschinen AGInventors: James Brian Vrotacoe, Richard Karl Weiler

Patent number: 6691614Abstract: A printing sleeve for use in flexographic or gravure printing applications is provided. In particular, the printing sleeve contains a bridge layer that is formed from a generally rigid and relatively expandable material, which is disposed adjacent to a core layer. For example, in one embodiment, the bridge layer is made from a polyurethane material having a Shore D hardness of about 20 to about 85. As a result of the present invention, printing sleeves can be formed to be more durable and maintain better TIR tolerances than conventional printing sleeves.Type: GrantFiled: June 15, 2001Date of Patent: February 17, 2004Assignee: Rossini North America, Inc.Inventors: Michael Bell, Felice Rossini

Patent number: 6637331Abstract: A blanket to be mounted on a blanket cylinder includes a blanket body and two band sheets serving as reinforcing members and attached to corresponding parallel, opposite end portions of the blanket body across a width of the end portions. One of the band sheets is attached only to one end portion of the blanket body and only on a side of the blanket body which comes into contact with the blanket cylinder when the blanket is mounted on the blanket cylinder. The other band sheet is longitudinally folded in two and is attached to the other end portion of the blanket body such that the other end portion is sandwiched therebetween and the other band sheet has a substantially same thickness on each side of the other end portion.Type: GrantFiled: September 25, 2001Date of Patent: October 28, 2003Assignee: Tokyo Kikai Seisakusho, Ltd.Inventors: Toshio Hasegawa, Kenji Kusunoki, Yukitoshi Takahashi
