  • Patent number: 10597804
    Abstract: Provided is a multiple woven gauze fabric capable of controlling the degree of wrinkling according to use. A double woven gauze fabric is formed by stacking a front surface gauze structure A and a back surface gauze structure B. The front surface gauze structure A and the back surface gauze structure B are formed, and the front surface gauze structure A and the back surface gauze structure B are joined, as appropriate. The front surface gauze structure A is composed of a non-twist yarn, and the back surface gauze structure B is composed of a hollow yarn. That is, a gauze structure composed only of twisted yarn (solid yarn) is not included. The degree of wrinkling is controlled by considering the hollow rate of the hollow yarn.

The surface roughness RZ of the shoe-contacting surface is between 50 and 500 microns; the particle diameter of the powdery material is between 5 and 500 microns; and the content of the powdery material in the high molecular weight elastic section is between 5 and 50 percent by weight. A lubricant is held in the minute projections and recesses, and consequently more lubricant may be supplied between the belt and the shoe with which it cooperates. As a result, friction between the belt and the shoe is reduced, and less energy is required to drive the papermaking machine.

  • Patent number: 6811863
    Abstract: In a printing press and attached onto the transfer cylinders, an anti-marking system that uniformly supports the transport and the release of the wet printed sheet from one station to the next. The anti-marking sheet consists of a two plus layer system, the outer layer being a textured surface and the inner layer being a microcellular material that is both compressible and resilient. The outer textured layer may be treated with either conductive/anti-static layers or an ink repellent layer or both. The two plus layer system is easily attached to both transfer cylinders and tracking/skeleton wheels using any combination of fixtures from Velcro™, magnetic, metallic, and pressure sensitive double sided tape to elastic loops.

  • Patent number: 6799512
    Abstract: A rubber cylinder sleeve for an offset printing press includes an inner carrier sleeve that has a circumferential and an axial direction. The carrier is expandable outwardly by an application of compressed air from the interior. The rubber cylinder sleeve also includes a single rubber layer having an inner surface disposed on the inner carrier sleeve and an outer surface for contacting the printing plate. The single rubber layer includes a plurality of compressible elements for increasing the compressibility of the single rubber layer and a plurality of filaments for increasing the stiffness of the single rubber layer. The compressible elements and the filaments are disposed at a distance from the outer surface.

  • Patent number: 6691614
    Abstract: 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.
