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] Next, the present invention will be described more specifically by way of examples. However, the present invention is not limited by the following examples.

[0053] The contact 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 roller. Thus, an evaluation test (simulation) was performed when each pressure contact roller was used as a nip roller. In Examples 1 to 4 and Comparative Examples 1 and 2, the length of the contact roller (outer tube) was 3200 mm, and the material of the outer tube and the central shaft was CFRP (carbon fiber reinforced resin) with a longitudinal modulus of 294.2 GPa. In addition, in Table 1, the so-called gap refers to the distance between the outer surface of the central shaft and the inner surface of the outer tube, and the so-called joint length refers to the length of the junc...

Abstract

The invention provides a pressure contact roller and a manufacturing method thereof. The pressure contact roller (1) is a pressure contact roller that is pressed against a predetermined opposite roller through a thin sheet. The pressing roller (1) has: a central shaft (2) having an outer surface (2a) as a cylindrical surface; On the outside, a cylindrical outer tube (3) joined to the central axis (2) at the central portion (2c) of the central axis (2) in a direction parallel to the center line (L). The central shaft 2 is made of a material having a longitudinal modulus of 190 GPa to 470 GPa, and the outer tube 3 is made of a material having a longitudinal modulus of 100 GPa to 470 GPa. The distance between the outer surface (2a) of the central axis (2) and the inner surface (3b) of the outer tube (3) is equal to or less than the outer diameter of the outer tube (3) × 0.10mm.

Description

technical field [0001] The present invention relates to a pressure contact roller which press-contacts a predetermined opposing roller with a sheet, and to a method of manufacturing such a pressure contact roller. Background technique [0002] In the case of manufacturing thin long-sized articles such as plastic films, plastic sheets, and fabrics (hereinafter collectively referred to as "sheets"), as roll materials, intermediate products, or products in various processes, An operation of continuously sending out sheets or a receiving operation is performed. In such an operation, the running speed of the sheet is adjusted and / or the tension applied to the sheet is adjusted by holding the sheet between two opposing rollers while rotating the rollers to send and receive the sheet. A set of opposing rollers is typically composed of guide rollers and nip rollers that fix the shafts. The nip roller has a movable shaft, and is pressed against the guide roller through the sheet by...
