Claims

[Claims for Utility Model Registration] 1. The roll shafts 5 of the small-diameter wiping rolls 2 and 3 arranged in two upper and lower stages are connected to the upper frame 8, respectively.
In the roll wiper supported by a lower frame 9 and a lower frame 9, the outer peripheral surfaces of the upper and lower wiping rolls 2 and 3 are each lined with an elastic body 4 made of a hard polymer material, and both ends of the roll shaft 5 are lined with an elastic body 4 made of a hard polymer material. A shaft support bearing 6 is attached to the upper frame 8, and an upper back up roll group 10 is rotatably fixed to the upper frame 8 in the roll axis direction, and an upper wiping roll 2 is attached to the roll shaft support. A lateral groove 12 that allows the roll to pass through the upper back-up roll group 10 without contacting it, and a gap above the lateral groove 12 that is high enough to push up the outer peripheral surface of the upper wiping roll 2 until it is pressed by the upper back-up roll group 10. 13
A lower back-up roll group 11 is rotatably fixed to the lower frame 9 in the roll axis direction, and the lower wiping roll 3 is rotated until it comes into contact with the lower back-up roll group 11. A vertical groove 14 into which a shaft support bearing 6 that can be dropped is inserted is bored in the roll shaft support part, and the upper and lower frames 8 and 9 are provided with vertical movement devices 16 and 17, respectively. A roll wiper characterized by: 2 The hardness of the elastic body 4 made of hard polymer material is Hs
60 to 90. The roll wiper according to claim 1 of the utility model registration claim. 3. The roll wiper according to claim 1 or 2, wherein the diameters of the upper and lower wiping rolls 2, 3 are in the range of 30 to 100 mm. 4 The upper and lower wiping rolls 2 are attached to the roll shafts 5 of the upper and lower wiping rolls 2 and 3.
External cylinder bearing 7 that rotatably pivots the external cylinder of
The roll wiper according to any one of claims 1 to 3 of the utility model registration claims, to which is attached a roll wiper.
