Abstract
A wiper apparatus which sandwiches a strip plate 2 between upper and lower wiper rolls 3 and 4 to squeeze out a rolling oil adhering to the strip plate 2, wherein backup rolls 5, 6 for reinforcing the wiper rolls 3, 4 each have a single sleeve 14 rotatably supported by two bearings 13 on a roll shaft, and the bearings 13 on the upper and lower backup rolls 5 and 6 are disposed on the roll shafts with a shorter span than the barrel length of the sleeve, and in point symmetry. Thus, a contact linear pressure distribution of the wiper rolls 3, 4 on the strip plate 2 can be made uniform.

Wiper apparatus for a liquid material, which sandwiches a moving rolled material between upper and lower wiper rolls to squeeze out the liquid material adhering to the rolled material, comprising:
- upper and lower backup rolls for reinforcing the upper and lower wiper rolls, each of said backup rolls having a single sleeve rotatably supported by two bearings on a roll shaft, and wherein the two bearings on the upper and lower backup rolls are disposed on the roll shafts in mutually offset relationship relative to a center line of the rolled material and have a substantially shorter span than a barrel length of the sleeve and wherein the two bearings on the upper backup roll are offset from the two bearings on the lower backup roll and are in point symmetry about the center line of the rolled material.
Wiper apparatus for a liquid material, which sandwiches a moving rolled material between upper and lower wiper rolls to squeeze out the liquid material adhering to the rolled material, comprising:
- upper and lower pairs of backup rolls, comprising a right backup roll and a left backup roll, respectively supporting each of the upper and lower wiper rolls,
- each of the backup rolls including a single sleeve and a set of support bearings, and
- wherein the support bearings supporting the sleeves of the upper pair of backup rolls are disposed in mutually offset relationship in point symmetry about a center line of the rolled material adjacent the upper wiper roll, and the support bearings supporting the sleeves of the lower pain of backup rolls are disposed in mutually offset relationship in point symmetry about said center line adjacent the lower wiper roll and wherein the set of bearings on the upper pair of backup rolls are offset from the set of bearings on the lower pair of backup rolls.
