Abstract

PURPOSE:To obtain a web roll product having a uniform roll hardness in the direction of width by covering the outer peripheral part of the crownformed core metal of a touch roll with rubber and making the diameter in the direction of width uniform. CONSTITUTION:A touch roll is formed from a core metal 10 and a covering rubber 20, and said core metal 10 has the crown 11 having the max. diameter at the center part. Since the covering rubber 20 has a uniform diameter in the direction of width of the roll, the covering rubber 20 is thinnest at the center part, and becomes thicker at the side edges. When the wound surface of a web is pressed by the touch roll, the center part of the web is pressed stronger than at the side parts, and the exclusion of air at the center part is effectively executed. Therefore, a web roll product having a uniform winding hardness in the direction of width can be obtained, even with a touch roll having a uniform diameter. Therefore, the touch rolls having a variety of crowns and shapes are prepared previously, and a web roll product having high quality can be obtained by selecting the touch roll so that the favorable roll form can be obtained.

用される。When winding 9 nibs of conventional paper, Safe 7/1 synthetic resin film, etc., touch the surface of the layer on which the web is being wound.
A method of winding the material while keeping it in contact with the material is often used. The touch roll is indispensable in the surface wind method because the take-up core itself is rotatably supported, so it plays the role of a surface drive roll, but in the center wand method, the touch roll is essential. However, in order to adjust the winding hardness of the rolled product, those equipped with a function that can appropriately set the suppression are used.

構造につい℃は全く検討され℃いなかった。In this way, the amount of air intervening between the webs when the webs are wound up and moved to ℃ is g4!
This is an important function, and in the case of a synthetic resin film whose web is a non-air permeable material, it serves as a means to control the amount of air between the wound layers within an appropriate range. By the way, conventional Tough Steel is coated with natural or synthetic rubber and has a hardness within a predetermined range.
Regarding the surface material of the web, it is important to check whether it is an appropriate material in terms of durability, workability, surface friction coefficient, etc., and whether or not it is an appropriate material in terms of durability, processability, friction coefficient, etc. Although the selection of the optical surface hardness of the web-wound product has been studied, the structure of the touch rule for ensuring that the web-wound product has uniform winding hardness in the width direction has not been studied at all.

ッチロールは、軸方向（ロール幅方向）に均一な材質。The present invention was attempted in the process of developing a winding device in which a synthetic resin film wrapped product has uniform winding hardness in the width direction.
It was possible to achieve the desired effect. Conventional touch rolls have a uniform material in the axial direction (roll width direction).

達成できるものである。Hardness, Jljl *It has been standardized to be a coefficient in °C, but the conditions for winding the web are such that the accompanying air is excluded from the surface of the wound layer of the web. The central part of the winding layer has the lowest efficiency, and the outer end of the surface of the winding layer has the highest efficiency. Therefore, Celsius-wound products tend to be soft at the center and hard at the side edges in the width direction (the amount of interlayer air is large in the center and small at the side edges). In order to correct this phenomenon, it is possible to achieve this by creating a structure with a touch rule such that the central portion is suppressed higher than the side edges.

In particular, it is an object of the present invention to provide an improved cuuntilol.

樹脂フィルムの巻取装置である。Structure of the Invention The present invention provides an apparatus for winding a continuously supplied synthetic resin film onto a winding nub while pressing the surface of the film winding layer using a touch rule, in which the touch roll has a crowned core. This is a synthetic resin film winding device characterized by having 4 pieces of rubber wrapped around the outer periphery of the metal and having the same diameter in the width direction.

つ℃いることとなる。The feature of the present invention is that the core bar has a crown 11 with a bulge in the center so that it has the maximum diameter at the center of the roll, and the covered part has a crown 11 in the width direction of the roll. The diameters are the same.Therefore, the covering rubber is thinnest at the center of the seal and thicker at the side edges.

As a result, a wound product can be obtained with a touch roll of the same diameter and uniform winding hardness in the width direction.
