Problems solved by technology

[0008] However, the base element comprising the aforementioned convoluted narrow belt 23a cannot laterally increase the strength of the belt; therefore, there is a possibility that the press belt may be stretched laterally
In addition, since the narrow strip-shaped member 23a needs to be wound on the mandrel M, its preparation method will consume a lot of time.
Furthermore, this prior art makes it difficult to adjust the amount of overlap of the strip-like elements 23a which must partially overlap each other
When installed in a paper machine, this severe defect will cause the press belt to crack due to stress

Embodiment Construction

[0047] Below, will refer to Figure 1-8 To explain the specific implementation of the present invention.

[0048] In these figures, symbol 1 denotes the tape of the present invention. The belt 1 according to the invention comprises: a cylindrical high molecular weight elastic element 2 and a base element 3 arranged in the wall thickness of the high molecular weight elastic element 2 .

[0049] The above-mentioned base element 3 comprises a strip-shaped element 4 wound cylindrically in multiple layers over its width. As the belt-like member 4, a woven fabric made of warp and weft of a resin material impregnated with the high-molecular-weight elastic member 2 is preferably used.

[0050] When the above-mentioned textile has both ends, the positions of the starting end 4a and the terminal end 4b need to be considered.

[0051] This is required in order to have an overall uniform thickness when the strip-shaped element 4 is wound in multiple layers within its width. This means...

Abstract

An easily manufactured shoe press belt for a papermaking machine comprises a high molecular weight cylindrical elastic member having embedded within it, between its inner and outer walls, a multiple layer base member formed by winding a belt-like woven fabric. The layers of the base member are substantially axially coextensive, reinforce the belt against sideward elongation, and achieve uniform hardness and improved durability.

Description

technical field [0001] The present invention relates to a shoe press belt having an overall uniform hardness and excellent durability, and also relates to a method for producing a shoe press belt. Background technique [0002] Shoe presses have been used to squeeze out water in the press section of paper machines. As is well known, there are currently two types of shoe presses, open and closed presses. Since open presses require a larger installation space and have the disadvantage of dispersing oil, closed presses have become the mainstream in recent years. Figure 9 A closed shoe press is shown. [0003] exist Figure 9 Among them, the shoe pressing device 20 has a pressing roller 21 and a shoe 22. A belt 23 for the shoe press runs between the press roll 21 and the shoe 22 . The water-containing paper web P sandwiched between the upper needled felt 24 and the lower needled felt 25 is arranged so as to run between the shoe press belt 23 and the press roll 21 . Therefore...
