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.

A device for separating sheet material has an actuator and a sheet material holder coupled thereto. The actuator is designed for moving the sheet material holder. The sheet material holder is designed for receiving an individual sheet material piece from a sheet material stack in which the sheet material pieces are arranged in a layered manner one above another along a vertical direction. The actuator is designed to set the sheet material holder into an oscillating rotational movement about a rotation axis that lies substantially parallel to the vertical direction, in order to receive the individual sheet material piece from the sheet material stack.

A office machine including a data carrier transferring passage and a transmission assembly disposed in the data carrier transferring passage is provided. The transmission assembly includes a shaft disposed along a pivoting axial and a transferring roller pivoted with the shaft, wherein the transferring roller rotates along the pivoting axial. The transferring roller includes a body and multiple grooves. The body has a transferring surface and two supporting surfaces. The two supporting surfaces are connected with two sides of the transferring surface and pivoted with the shaft. The grooves are arranged on the transferring surface, wherein each groove has two end portions. At least one of the two end portions is not connected to the supporting surfaces.

A sheet feeding member is provided, which is made of a thermoplastic elastomer composition comprising: a base polymer including a polyurethane thermoplastic elastomer and a polyester thermoplastic elastomer; and at least one ion conductive agent selected from the group consisting of a quaternary ammonium salt and a lithium salt/polyol, wherein the ion conductive agent is present in a proportion of 0.2 to 4 parts by mass based on 100 parts by mass of the base polymer in the thermoplastic elastomer composition.

A document feeder for a printer may include an upper part and/or a lower part. The upper part may include a feeding roller arrangement configured to engage with an upper face of a document. The lower part may include a retaining surface. The lower part may further include a sliding element which, in at least an operation mode of the document feeder, may have a portion that projects with respect to the retaining surface for supporting a lower face of the document in such a way that at least a portion of the document is raised with respect to the retaining surface.

A belt having a first cover layer with a first top surface and preferably also a second cover layer with a second top surface, wherein the first cover layer and, if present, the second cover layer are made of a foam having a thermoplastic or thermoplastic elastomer, in particular a TPU or PEBA. The belt is suitable e.g. as a machine tape in mail sorting machines and for power transmission.

The invention relates, inter alia, to a damping element for a container receiving pocket of a container transport starwheel. The damping element has an elastically deformable damping section which has a contact face for contacting a container. The damping element has a preferably elastically deformable mounting section for mounting the damping element in the container receiving pocket of the container transport starwheel. The damping section and the mounting section are formed from a plurality of adjacent, preferably additively manufactured, material layers.

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 m2.5 m square of the elastic material layer 14.
