A support element for a feed roller for a fibre material, preferably a precursor fibre, to be used in an oxidation or carbonization line for producing carbon fibres, including a base provided with means for attachment to a structure or frame of the oven, a support ring coupled with the base and having at least one passing-through opening for receiving one end of the feed roller, and adjustment means operatively interposed between the base and the ring, and configured to move the position of the ring with respect to the base along at least one adjustment direction, transverse to a central axis of the opening, in order to adjust the position of the ring as a function of the deformations of the roller.

A strip diverting mechanism includes a negative pressure unit and an air discharge unit. The negative pressure unit and the air discharge unit are arranged opposite each other, and a gap through which a strip passes is formed between the negative pressure unit and the air discharge unit. The negative pressure unit is configured to provide a suction force to the strip and the air discharge unit is configured to provide a repulsive force to the strip, to prevent the strip from contacting the negative pressure unit and the air discharge unit. The negative pressure unit comprises two air channels located at two sides of the negative pressure unit and configured to discharge air to a direction away from the negative pressure unit, to generate a negative pressure area at a center of the negative pressure unit.

A web path for conveying a web material includes at least two support rollers contacting a single major surface of the web material, wherein the web material is of indefinite length and has a first and a second edge. A first support roller contacts a first edge region of the web material, and a second support roller contacts a second edge region of the web material such that the web material has a substantial un-contacted region between the first and the second support roller including at least about 50% of the width of the web material. At least one of the first support roller and the second support roller are supported on a bowed shaft such that at least one of the first and second support rollers is angled with respect to the direction of motion of the web.

Systems and methods are provided for configuring media transport flow paths for directing input image receiving media, including of different types, in sheet or roll form from multiple axes to provide wider latitude in selecting particular input image receiving media and combinations of input image receiving media to support execution of a print job. The disclosed schemes are directed at using one or more stationary turn bars disposed generally at 45 in an input media transport path approaching a marking module in an image forming system to allow for sheets or sheeted materials to be positioned at 90 to the in-line input image receiving media transport path directed toward the marking module thus allowing for flexibility in selection among various sources of stacked, pallet and rolled media.

A medium feeding apparatus includes a driving portion that drives a feeding roller, an arm portion that supports the feeding roller, and a displacement portion that can come into contact with the arm portion. The arm portion displaces the feeding roller between a contact position and a separation position. The contact position is a position where the feeding roller comes into contact with the medium, and the separation position is a position where the feeding roller is separated from the medium. The displacement portion rotates the arm portion to displace the feeding roller from the separation position to the contact position by using forward rotation power from the driving portion, and rotates the arm portion to displace the feeding roller from the contact position to the separation position by using reverse rotation power from the driving portion.

A belt-form body conveyor that conveys a belt-form body includes a plurality of non-contact guide portions over which portions of the belt-form body are wound, and that support the belt-form body in a non-contact manner, and a drive unit that, when viewed in a direction that is perpendicular to a surface of the belt-form body before the belt-form body is supplied to the plurality of non-contact guide portions, causes at least two non-contact guide portions out of the plurality of non-contact guide portions to rotate in the same direction and by the same angle.

A reversing device for a film web, which has a take-off device, has at least one turning device and at least one deflecting roller. The film web can be guided by the take-off device via the at least one turning device and the at least one deflecting roller to a winding device. The axes of the take-off device, the at least one turning device, and the at least one deflecting roller are adjustable in angle relative to one another. The at least one deflecting roller is formed as an expander roller having an expanding capacity which increases towards the end faces of the deflecting roller.
