In example implementations, a printer module is provided. The printer module includes a co-axial split drive roller, a first motor, a second motor, and a print bar. The co-axial split drive roller includes a first roller and a second roller that are movably coupled at a center of the co-axial split drive roller. The first motor is coupled to the first roller. The second motor is coupled to the second roller. The print bar is coupled to the housing over the co-axial split drive roller.

The present disclosure relates to a residual film winder for a packaging machine, wherein the residual film winder comprises a reception mandrel, a reception sleeve, and at least one film spreader. The reception sleeve is configured to be arranged onto the reception mandrel. The film spreader has a first end and a second end, wherein the first end extends out of the reception sleeve, and the first end has an outer contour extending along its long axis. The outer contour of the film spreader has at least two sections, a first section and a second section, wherein the first and second sections are not parallel to each other.

An expander roller for a fold-free expansion of foils, webs, and sheet materials in a width dimension. The expander roller has a central metal axle mounted in a surrounding synthetic tube with placed on its circumference a grid of implanted brush plugs in an axial direction under an angle alpha and with a mutual distancing and in tangential direction under a center angle beta and with a mutual distance. The roller provides a perfect expanding or stretching of thin widths of different materials.

The invention relates to a device, comprising: a spreader roll (2), the spreader roll having a roll tube (3), over which a material web is guided, the bending of the spreader roll (2) about its longitudinal axis allowing the material web to be spread out; and two bearing journals (4), which are operatively connected to the roll tube (3) and are pivotably articulated in a machine frame (1), the bearing journals (4) being mounted on the machine frame (1) by means of pivotable bearings (6) and the bearing journals having longitudinal pins (5) protruding beyond the bearings (6), at the ends of which longitudinal pins radially acting adjustment means (7) are positioned.

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.

Provided are a roll, a film forming apparatus, and a film forming method. The present invention provides a roll used in an apparatus which may transfer a substrate, e.g., a flexible substrate such as a plastic film and a fibrous or metallic web or film and may form a film on a surface of the substrate, a film forming apparatus including the roll, and a film forming method using the film forming apparatus.
