  • Oil-coating roller
    Patent number: 6869385
    Abstract: An oil-coating roller constituted mainly of an oil-retaining layer around a central core and an oil-coating control layer surrounding the oil-retaining layer is provided which does not require a sealing treatment for prevention of oil leakage from the roller end face, and has a long service life. The oil-retaining layer is formed by winding in layers a nonwoven fabric which exhibits an oil-sucking height of not less than 60 mm and has an oil permeability of 40 g/cm2/hr.

  • Member for oil application device, method of manufacturing the member, and oil application device
    Patent number: 6666939
    Abstract: A tubular member for an oil application device is formed separately and is fitted in such a manner as to cover a peripheral face of a porous cylindrical oil retaining member. The tubular member for the oil application device has a multi-layer structure including an inner layer and an outermost layer. The inner layer is a fibrous layer, and the outermost layer is a porous film. The porous cylindrical oil retaining member can be easily covered with, fitted with, and removed of the member for the oil application device, which is made from a fibrous layer such as a felt or from a porous film such as a PTFE film.
