Abstract

The DC60 press belt with support for paper manufacturing comprises a seamless first resin layer formed on the polished surface of the cylindrical shaft; a textile base layer consisting of a textile sheet arranged over the entire outer perimeter of the first resin layer, with at least one set of interwoven high-strength yarns extending axially along the cylindrical shaft; a yarn bundle layer consisting of high-strength yarns twisted circumferentially on the outer perimeter of the textile base layer; and a seamless second resin layer on the outer perimeter of the yarn bundle layer. The second resin layer comes into contact with the first layer through the textile base layer and the yarn bundle layer. Press belts constructed in this manner exhibit high strength in both the machine and transverse directions. A seamless first resin layer is formed on the polished surface of the cylindrical core. The textile base, composed of textile sheets, is arranged over the entire outer perimeter of the first resin layer. At least one set of interwoven textile yarns, which are high-strength yarns, extend axially along the cylindrical core. A yarn group layer consisting of high-strength yarns is twisted circumferentially on the outer perimeter of the textile base layer, and a seamless second resin layer is located on the outer perimeter of the yarn group layer. The second resin layer comes into contact with the first layer through the textile base layer and the yarn group layer. The press belt, constructed with this type of compression support, exhibits strength in both the machine and transverse directions.

Claims (4)

1. The conveyor belt of a press machine has a support structure consisting of a seamless first resin layer (2) with a smooth inner surface in the form of a single-axis rotating surface; the first resin layer (2) with an outer circumference; the base textile layer (3) consisting of a textile sheet (P) arranged over the entire outer circumference of the first resin layer (2); the textile sheet (P) consisting of multiple sets of intersecting yarns (S,Y) and at least one set of these multiple sets of intersecting yarns (S,Y) being high-strength yarns (S) extended axially along the base textile layer (3); the yarn group layer (4) consisting of high-strength yarns (Sy) twisted in a circumferential manner on the outer circumference of the base textile layer; and a seamless second resin layer (5). Located on the outer perimeter of the yarn layer (4), the second resin layer (5) is in contact with the first resin layer (2) via the base textile layer (3) and the yarn layer (4). 2. The belt of the compression press, according to claim 1, in which the smooth inner surface of the first (2) resin layer, which is seamless, is in the form of a cylinder, and in which at least one such set of threads of intersecting threads (S,Y) is extended parallel to such axis. 3. The belt of the compression press with a support under claim 1, where the first (2) seamless resin layer is formed on the polished surface of the rotating cylindrical shaft. 4. Method for the fabrication of the belt of a press with a support section. The fabrication method consists of the following steps: the formation of a seamless first resin layer (2) on the polished surface of the rotating spindle; the formation of the base tubular layer (3) by placing it over the entire outer circumference of the first resin layer (2); a tubular sheet (P) composed of several sets of intertwined yarns (S,Y), at least one set of which is a high-strength yarn, so that the yarn (S) of one such set of (S,Y) extends in the axial direction of the spindle; the formation of the yarn group layer (4) by wrapping the high-strength yarn (Sy) around the outer circumference of the base tubular layer (4) in a spiral pattern; and finally, the formation of a seamless second resin layer (5) on the outer circumference. The outer part of the yarn layer (4) thus comes into contact with the first resin layer (2) through the base layer (2) and the yarn layer (4).
