The invention relates to a carriage of a linear motion guide for arranging on a rail of the linear motion guide, said carriage having an at least substantially U-shaped cross-section and having at least one substantially U-shaped base body (15) which is supplemented with plastic components, wherein the carriage, in both legs of the U-shape, is in each case connected to at least one self-contained rolling body housing (7) which is kept open towards the rail in order to guide as precisely as possible on the rail and nevertheless being easy to assemble. According to the invention, at least parts of inner and outer boundary surfaces of a return channel (10) and both deflection channels (11) of one of the rolling body housings in the respective leg are formed by means of a one-piece plastic component in both legs of the carriage.

A roller (10) for converting tape material comprises a cylindrical pressure surface (11) defined by a coating element (21) made of resilient material of predefined hardness applied over a plurality of resilient annular pressure elements (15) made of elastic deformable material arranged axially side by side, so as to obtain an overall elastic yielding of the roller (10) independent from the superficial elastic yielding.

A roller device for guiding a flexible substrate is described. The roller device includes a support surface for contacting the flexible substrate, the support surface having a coating comprising an electronegative polymer. Further, a vacuum processing apparatus for processing a flexible substrate including the roller device and a method of processing a flexible substrate in the vacuum processing apparatus is described.

The invention relates to a roll for use in a manufacture of a fibrous web, which comprises cellulosic fibers. The roll comprises a roll body with a cylindrical surface, and a roll cover, which is arranged to cover the cylindrical surface of the roll body. The cover has a functional layer, which has a polymer matrix and reinforcing material in the form of functional particles and/or functional fibers embedded in the polymer matrix. The functional particles and/or functional fibers has nanocellulose material. The invention relates also to the use of the roll.

A medium transport device includes a roller transporting a medium, such as recording paper; a first layer covering a surface of the roller facing the medium; a second layer laminated on the first layer; and convex portions provided between the first layer and the second layer, and the convex portions are formed from inorganic particles. The first layer binds the convex portions to the roller, and the second layer covers the convex portions for protection.

An elastic roll includes: a roll core; an inner-layer laminate covering an outer-peripheral surface of the roll core parallel to a roll longitudinal direction; a surface-layer elastomer including a tubular portion covering an outer-peripheral surface of the inner-layer laminate, and edge portions connected to the tubular portion, covering both end surfaces of the inner-layer laminate orthogonal to the roll longitudinal direction, and arranged in a manner being in contact with the roll core; and end-portion sealing structural bodies configured to press the edge portions of the surface-layer elastomer against the roll core.

There is provided a roller including: 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 a plurality of first recessed portions which are provided on one side of the roller in a shaft mounting direction at intervals in a circumferential direction of the roller and each have a bottom portion, and a plurality of second recessed portions which are provided on the other side of the roller in the shaft mounting direction at intervals in the circumferential direction of the roller and each have a bottom portion, and in which each of the first recessed portions is positioned between the adjacent second recessed portions in the circumferential direction of the roller in the side view of the roller in the shaft mounting direction.

A roll excellent in abrasion resistance, which contains: a resin layer containing a first atom group having a plurality of sulfur atoms, a plurality of second atom groups having a carbon chain that has a plurality of carbon atoms arranged in a line and has an end bonded to any one of the plurality of sulfur atoms, and a plurality of third atom groups each of which has a urethane bond and is bonded to any one of the plurality of second atom groups; and a cylindrical foamed resin having an outer surface covered with the resin layer.

A roller is described for an irradiation apparatus, wherein the roller is designed to guide a material web to be irradiated past at least one electron emitter. The roller comprises a first end face region of the roller, wherein the diameter of the first end face region is smaller than the diameter of the roller, and a jacket surface of the roller, which takes the form of a jacket surface of a right circular cylinder. The jacket surface extends in the axial direction from a first axial position to a second axial position of the roller, wherein the first axial position has an axial spacing from the edge of the first end face region which amounts to between 3% and 25% of the length of the roller, and wherein the second axial position is further away from the first end face region than the first axial position. The roller comprises a first curved transitional region, which extends from the edge of the first end face region annularly and continuously as far as the first axial position of the roller. Viewed in a longitudinal plane through the center axis of the roller, a curvature of the contour of the roller at the transition from the first end face region to the first curved transitional region, within the first curved transitional region and at the transition from the first curved transitional region to the jacket surface is in each case less than a maximum curvature which corresponds to a minimum radius of curvature of 5% of the diameter of the roller.

A presentation device for presenting a ticket from a printer includes first and second reels, a ticket holder and a housing component. In operation, the first reel contacts a first side of the ticket, and the second reel contacts a second side of the ticket opposite to where the first reel contacts the first side of the ticket. As the ticket advances from the presentation device, gravity pushes the ticket down onto the ticket holder, which is a reel. The first reel, the second reel and the ticket holder are secured in the housing component. The housing component is pivotable about a rotating axis and has a supporting notch that supports the second reel. The supporting notch has a first guide edge surface that faces away from the rotating axis, a second guide edge surface, and a trough between the first guide edge surface and the second guide edge surface.
