In many continuously webbed machines, media is fed through the machine with rollers mounted to one or more rotating shafts. These shafts may be supported on each end with a cylindrical journal bearing. The rollers move at the same rate as the media to maintain traction with the media to control media position as it moves the media from one process to another through the sequence of processes in the webbed machine.

A dispenser for dispensing sheet product is provided. The dispenser includes a housing with an outlet through which sheet product is dispensed. A knife drum is rotatable with respect to the housing. A knife is movable between a retracted position within the knife drum and an extended position where the knife protrudes outside of the knife drum to cut the sheet product. A cam follower surface is fixed with respect to the housing. A cam follower is attached to the knife and operable to engage the cam follower surface and travel therealong to transition the knife between the retracted position and the extended position. A spring assembly biases the knife drum during rotation toward a predetermined position. The spring assembly comprises a first spring and a second spring. The spring assembly is attached at a single mount position that is fixed with respect to the housing.

A dispenser for dispensing sheet product is provided including a housing that defines an interior configured to accommodate a source of sheet product and an outlet through which the sheet product is dispensed. The dispenser also includes a first roller that is rotatable and disposed in the housing. A portion of the sheet product is designed to be in contact with the first roller prior to being dispensed through the outlet. The dispenser also includes a knife drum that is rotatable and configured to cooperate with the first roller to dispense the sheet product. The knife drum includes a knife configured to cut the sheet product into individual sheets. The dispenser also includes a spring assembly that may be configured to bias the knife drum toward a predetermined position during rotation of the knife drum.

A brush roll configured to support a material web, in particular a web of corrugated board, comprises a roll core and arcuate shells, which are each arranged on the roll core and comprise bristles arranged on the outside. The brush roll further has fastening assemblies configured to fasten the arcuate shells to the roll core. Each of the fastening assemblies has a fastening body, which is locally fastened to the roll core, which locally fastens at least one of the arcuate shells to the roll core, which has a foot part, connected to the roll core, with a bottom, and a head part, connected to the foot part, with a lower side facing the roll core, said lower side forming at least one lower wedge face for engagement with at least one of the arcuate shells.

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.

Provided is an uneven roller of which a surface coming into contact with a medium is provided with a plurality of protrusions and recesses, the uneven roller including a shaft portion, a reference portion mounted on the shaft portion, a ring portion that is positioned closer to a side, to which a first direction along an axial direction of the shaft portion extends, than the reference portion is and that is mounted on the shaft portion, and a restriction portion that is positioned closer to the side, to which the first direction extends, than the ring portion is and that is mounted on the shaft portion to restrict movement of the ring portion in the first direction. The ring portion is composed of a plurality of uneven rings disposed along the axial direction, the uneven ring including a plurality of protrusion portions disposed along a circumferential direction.

A recording apparatus includes a transport unit capable of transporting a medium, a detection unit capable of detecting a transport direction in which the transport unit transports the medium, a recording unit capable of performing recording on the medium transported by the transport unit, and a plurality of rotating bodies provided in an intersecting direction that intersects the transport direction. Each rotating body is capable of contacting a side surface of the medium opposite to a recording surface of the medium on which recording is performed by the recording unit and has a rotation shaft that extends in the intersecting direction. The apparatus further includes a control unit that controls rotation speed of each rotating body individually on the basis of a result of detection by the detection unit.
