Abstract

PURPOSE: To make it possible to obtain uniform pressure under the state where a pair of fixing rollers are held in parallel, by sagging the pressure applying material by applying a load to both end parts of the pressure applying material and by compressing it to the inside circumference face of a hollow roller from one end side to the other end side.
CONSTITUTION: Upper and lower pipe rollers are held displaceably in the pressure applying direction, and shafts 2 and 5 for pressure applying receive a high load at both ends through bearings 6 and 6' and the side plate by springs 7 and 7'. Therefore, shafts 2 and 5 are sagged with discs 23 and 53 as fulcrum materials respectively, and discs 21, 22 and 23 and discs 51, 52 and 53 provided on shafts 2 and 5 are compressed uniformly to inside faces of corresponding rollers 1 and 4 in positions corresponding to roller compression line parts. By this constitution, uniform pressure can be obtained without sagging of a pair of fixing rollers under the state where they are held in parallel.
