A method of winding a pre-impregnated fabric strip onto a sloping surface includes a step of deforming the pre-impregnated fabric strip by applying differing traction forces to the pre-impregnated fabric strip, the traction forces being directed in a longitudinal direction of the strip, the values of the applied traction forces differing across the transverse direction of the strip. The differing traction forces are applied by tensioning the pre-impregnated fabric strip between firstly a pair of brake rollers and secondly a traction device present downstream from the pair of brake rollers, the traction device driving the pre-impregnated fabric strip at speeds that differ across the transverse direction of the strip. The method further includes winding the deformed strip onto a surface of revolution of winding tooling including at least one portion that forms a nonzero angle with the axis of revolution of the surface of revolution.

A calender transport roller for a calendering device for production of electrodes for a battery cell, where an electrode strip is conveyable by the calender transport roller to or from a pair of calendering rolls and where the electrode strip has a flat conductor strip and a coating which is applied in portions at least on a side that faces the calender transport roller. The calender transport roller includes a contact region on a shell surface of the calender transport roller where the contact region is contactable with the electrode strip, an adjusting portion in the contact region, and a widening device where a diameter of the transport roller in the adjusting portion is changeable by the widening device such that a height difference between a coated portion of the electrode strip and an adjoining uncoated portion of the electrode strip is compensated.

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.

The invention provides a paper feed roller capable of reducing abnormal noise caused by a knurled shape while maintaining characteristics thereof, including maintaining friction coefficient and coping with paper powder. The paper feed roller comprises a roller body formed of elastic material in a cylindrical shape and is characterized in that the roller body has protruding lines and recessed grooves inclinedly extending relative to an axis of the roller body so that convex and concave portions having predetermined widths are alternatively formed in a circumferential direction of a peripheral surface, and the protruding lines have one-end side protruding line portions extending from a central part in an axial direction of the roller body toward one end thereof and other-end side protruding line portions extending from the central part in the axial direction toward the other end, and they are inclined relative to the axis in opposite directions.

The present disclosure describes a spreader roll (101) that can help spread webs laterally in a web processing operation, in particular to reduce or remove the presence of wrinkles or bagginess in the web. The spreader roll can be a reverse crown roll that is covered with a resilient material (160) to assist spreading the web to remove wrinkles. The surface curvature of the spreader roll (101) can be formed using layers of material such as a tape, to easily and readily approximate the shape of a reverse crown roll.

A print media moving apparatus includes a web guide positioned immediately upstream relative to a roller. The web guide has an arcuate surface including three sections with the second section located between the first and third sections. The arcuate surface includes a peak in the second section. The roller, having a diameter and rotational axis, includes three sections with the second section located between the first and third section as viewed along the rotational axis. The diameter of the roller in the first and third sections is greater than in the second section. The three sections of the web guide correspond to the three sections of the roller such that the contour of the arcuate surface causes the print media, after leaving the web guide, to contact the first and third sections of the roller prior to contacting the second section of the roller.
