Provided are a rubber composition capable of imparting a high tensile strength to a roller main body so as to be able to be used for equipment that allows paper to pass through at high speed, while maintaining high abrasion resistance of the roller main body and a favorable paper feeding performance of the paper feeding roller; and a paper feeding roller. There is provided a rubber composition contains: a rubber that includes a non-oil extended EPDM having an ethylene content of 55 to 72%; and more than 20 parts by mass and 30 parts by mass or less of a filler, and 2.5 parts by mass or more of a peroxide crosslinking agent per 100 parts by mass of the rubber, in which the filler contains 15 to 30 parts by mass of an amorphous silica per 100 parts by mass of the rubber.

The present invention addresses the problem of providing a bill conveying roller base having an excellent swelling resistance. In order to solve this problem, the bill conveying roller base is provided with an elastic layer covering at least part of the outer peripheral surface, the elastic layer comprising a thermosetting polyurethane which is obtained by reacting polyol components containing a lactone-based polyol with polyisocyanate components containing methylene diphenyl diisocyanate (MDI).

A reusable, one-piece, rubberized tape protector cover for a roll of tape that fits snugly onto the roll to protect its edges from coming into contact with dirt or moisture that might be on the floor. The device has a spindle of varying widths to accommodate different thicknesses of tape and two parallel side walls that extend outward from the spindle in wheel-like fashion. The device is installed on a roll of tape by compressing one of the two side walls and then pushing the compressed side wall through the hollow center of the roll of tape before releasing it. When released, the side wall resumes its former shape. In this installed position, the spindle is located within the hollow part of the roll of tape and the two parallel side walls extend on either side of the roll of tape and hug the side edges of the tape.

A roller includes a shaft, and an elastic body portion that is provided on an outer peripheral surface of the shaft, in which the elastic body portion includes an inner peripheral portion which becomes a shaft side, an outer peripheral portion which becomes an outer side with respect to the inner peripheral portion, a plurality of first connection portions which connect the inner peripheral portion and the outer peripheral portion, and a plurality of second connection portions which are provided in a space portion between the adjacent first connection portions and which partition the space portion into one side and the other side of the roller in the axial direction, and in which the first connection portion is inclined in the same direction in a peripheral direction with respect to a radial direction of the roller.

A sheet feed roller (1) is provided, which is formed of an elastomer composition containing a thermoplastic elastomer, a spherical filler and a low friction silicone compound, and has a friction coefficient of not greater than 0.5. A production method is also provided, which includes the step of extruding the elastomer composition through a die configured as corresponding to a sectional shape of the sheet feed roller.

Provided is a paper feeding roll that is capable of reducing conveying noise and suppressing adhesion of paper dust. A paper feeding roll (10) is provided with: a shaft body (12); and an elastic body layer (14) that is formed on the outer circumference of the shaft body (12), wherein the elastic body layer (14) is a foamed body that contains hydrin rubber, and has a cavity (18) formed of foaming cells (16) being connected with one another is located radially inward of the elastic body layer (14). The average diameter of the foaming cells (16) located inward of the elastic body layer (14) in the radial direction is larger than the average diameter of the foaming cells (16) located outward in the radial direction. Recesses (20b) formed of foaming cells (16) being opened are provided to the outer circumferential surface (14b) of the elastic body layer (14).

There is provided a rubber composition in which an antistatic agent is uniformly dispersed and the rubber composition has antistatic ability, coefficient of friction, and wear resistance. A rubber composition includes 7 parts by mass or more of a polyether/polyolefin block copolymer resin with respect to 100 parts by mass of a rubber component, and the total amount or a part of a rubber component is mixed with a polyether/polyolefin block copolymer resin at a temperature that is equal to or higher than a melting point of the polyether/polyolefin block copolymer resin.

The present disclosure provides a paper feed roll that inhibits conveyance failure even during long term use by suppressing unevenness in the surface of an elastic material layer when the elastic material layer is formed by two or more phases. A paper feed roll 10 according to the present disclosure is provided with a shaft body 12 and an elastic material layer 14 formed on the outer peripheral surface of the shaft body 12. The elastic material layer 14 includes a first phase containing ethylene propylene diene rubber and a second phase containing one or more of either isoprene rubber or natural rubber. The area ratio of the second phase is within the range of 30% or more and 70% or less in a range of any given 2.5 ?m?2.5 ?m square of the elastic material layer 14.

A sheet conveying device includes a sheet conveying passage and a switching guide. The switching guide switches the sheet conveying passage between first and second sheet conveying passages. The switching guide includes a plurality of guide ribs and guide members. The plurality of guide ribs are disposed at intervals in the sheet width direction and extend in the sheet conveying direction. The guide members are fitted to specific guide ribs selected from the plurality of guide ribs. The plurality of guide ribs have first and second guide surfaces that guide the sheet. The guide members are formed of a material having higher slidability than the plurality of guide ribs, and have third guide surfaces that are disposed at positions protruding further to an inner side of the sheet conveying passage than the first or second guide surfaces.
