Abstract
A device for fixing a sheet material to a cylindrical rotating member. Without using a suction mechanism and a vacuum, pressing portions of sheet material leading end clamps provided at a peripheral surface of the rotating member press the sheet material against the peripheral surface of the rotating member and fix the sheet material thereat. Each pressing portion has a region which deforms most due to centrifugal force generated by the rotating member. The pressing portion is formed in advance on the whole in a bow-like shape such that this region projects the most toward a center of the rotating member. Due to deformation caused by centrifugal force, the pressing portion changes from bow-shaped to planar, and uniformly presses the sheet material without a gap therebetween.
Claims16
A sheet material fixing device comprising:
- a rotating member which is rotatable and on whose peripheral surface a sheet material is disposed;
- a holding member provided at the peripheral surface of the rotating member;
- and
- a pressing portion provided at the holding member, and formed so as to project more toward the rotating member the further toward positions of the pressing portion where an amount of deformation thereof in a direction of moving away from the rotating member due to centrifugal force at the time when the rotating member rotates increases, the pressing portion pressing the sheet material against the peripheral surface of the rotating member.
