Problems solved by technology

The reason for this is that if the sheet is not evenly nipped by the guide rollers and nip rollers, there is a risk that the sheet will zigzag in the width direction in the slitting section, or damage to the sheet will occur in the slitting section.

Embodiment

[0052] Hereinafter, the present invention will be described in more detail by way of examples. However, the present invention is not limited by the following examples.

[0053] The contact pressure rollers of Examples 1 to 4 and Comparative Examples 1 and 2 were prepared under the conditions shown in Table 1, and an equally distributed load of 200 kgf (=1.96 kN) was applied to the entire length of each contact pressure roller. Thereby, the evaluation test (simulation) when each contact pressure roll was used as a nip roll was performed. In Examples 1 to 4 and Comparative Examples 1 and 2, the length of the contact pressure roller (outer tube) was 3200 mm, and the material of the outer tube and the center shaft was CFRP (carbon fiber reinforced resin) with a longitudinal elastic modulus of 294.2 GPa. In addition, in Table 1, the “gap” refers to the distance between the outer surface of the center shaft and the inner surface of the outer tube, and the “joint length” refers to t...

Abstract

The invention provides a contact roll and a manufacturing method thereof. The contact roll (1) is a contact roll which presses an opposite roll via a thin sheet. The contact roll (1) includes a central shaft (2) which serves as an outer surface (2a) of a cylinder surface, and a cylindrical outer pipe (3) which is configured on an outer side of the central shaft (2) in a manner that the outer pipe has a center line (L) identical to that of the central shaft (2), and is joined with the central shaft (2) at a central part (2c) of the central shaft in a direction parallel to the center line (L). The central shaft (2) is made of a material having a longitudinal elasticity modulus above 190GPa and below 470 GPa. The outer pipe (3) is made of a material having a longitudinal elasticity modulus above 100 GPa and below 470 GPa. The space between the outer surface (2a) of the central shaft (2) and an inner surface (3b) of the outer pipe (3) becomes to an outer diameter below x 0.10mm.

Description

technical field [0001] The present invention relates to a contact pressure roll that is press-contacted with a predetermined opposing roll through a sheet, and to a method for producing such a contact pressure roll. Background technique [0002] In the case of manufacturing long-sized articles with relatively thin thickness such as plastic films, plastic sheets, and fabrics (hereinafter collectively referred to as "sheets"), in various processes, as rolled materials, intermediate products, or products, An operation of continuously feeding out sheets or a pick-up operation is performed. In such an operation, the traveling speed of the sheet is adjusted and / or the tension applied to the sheet is adjusted by pinching the sheet between the two opposing rollers while rotating the roller to send out and receive the sheet. One set of facing rolls is typically composed of guide rolls and nip rolls that fix the shafts. The nip roller is a contact roller that has a movable shaft, an...
