JPS60191955A - Construction for peripheral surface of conveyance roller of film conveyor - Google Patents

Abstract

PURPOSE:To easily replace a linear resin material, by winding the linear resin material of the peripheral surface of a roller to provide a prescribed construction. CONSTITUTION:A linear resin material 51 is wound on the peripheral surface of a roller in the circumferential direction thereof so that the turns of the wound material 51 are juxtaposed in the axial direction of the roller, and a circumferential groove 53 is formed between the turns of the material as if projections and sinkings were formed. The linear resin material 51 is made oblique, in the direction A of rotation of the roller 3, toward the axial center B of the roller which divides the assembly 52 of the turns of the material 51 into halves 52a, 52b in the axial direction, at least on the roller's portions which are to come into contact with a film. This results in facilitating the replacement of the linear resin material and bringing a good wrapped state.
