Claims

[Claims for Utility Model Registration] 1. On the outer peripheral surface of a hollow roll rotated by a roll shaft,
In a vacuum forming roll structure in which six grooves are vacuum formed on a film using concave grooves formed radially toward the center of the roll, the concave grooves face and communicate with the roll concave grooves and are disposed radially toward the center of the roll. , a vacuum passage penetrating the width of the roll in the roll axis direction, and a circular plate supporting the roll axis and disposed on the side surface of the roll, the circumference of which is arranged at a position in the radial direction opposite to the vacuum passage; A vacuum side plate having a groove of an appropriate length cut in a direction, a communication means for communicating this groove with a vacuum source, and attached to the roll side through the vacuum side plate and the roll. A true forming roll structure characterized by having a plain metal plate which is a flat plate and is formed by radially penetrating holes having approximately the same area at a position facing the vacuum passage. □2. The vacuum forming roll structure according to claim 1, wherein the vacuum passage is a round hole formed in a thick wall portion of the roll. 3. The vacuum according to claim 1, wherein the vacuum passage is in the form of a groove carved on the outer periphery of a hollow cylinder inserted into the inner diameter of the roll forming the concave groove. Molded roll construction.
