A chuck includes a central shaft defining an axis of rotation, a cam seat defined by the central shaft, and a support portion partially defining a first cavity having a first orifice at a first distal end of the support portion, the first orifice operative to engage the central shaft. The support portion includes The chuck further comprises a second orifice defined by the support portion, an expansion portion arranged in the second orifice such that the expansion portion is operative to move radially in the second orifice with respect to the axis of rotation, and a follower member arranged in the cam seat. The expansion portion includes an arcuate profile comprising a core relief feature having a spacer member arranged on a portion of the support portion, the spacer member operative to impede motion of a core of a roll of material along the axis of rotation

A system and method for cationization of textiles preferably starting with the dry raw greige tubular or open width goods that are made from either a cellulosic or cellulosic blended fabric. The system can include an inducer apparatus with chemical dosification system. In a preferred embodiment, the dry tubular goods are sent in a flat configuration to a first impregnation tank where it receives a multi-functional reaction fluid. After leaving the first impregnation tank, the now wet fabric is turned (when in a tubular width fabric form) by a turning unit and then sent to a second impregnation tank where it again is exposed to the multi-functional reaction fluid. The turning of the fabric causes the side edge positions of the flat tubular fabric to change its physics dynamics which allows for the multi-functional reaction fluid to be evenly applied to the entire fabric. Turning is not needed for open with fabric as it is flat, thus having only one dynamic when analyzed with physics.

An apparatus for rolling a bladder includes a support structure, a rolling pin, and a bladder-mounting pin. The apparatus optionally includes a rolling initiator Rolling a bladder includes inserting the bladder while unrolled into an apparatus for rolling a bladder, inserting the bladder between a rolling pin and a bladder-mounting pin of the rolling machine, and rotating the rolling pin to (a) advance a portion of the bladder between the rolling pin and the bladder-mounting pin, (b) roll the portion of the bladder around the bladder-mounting pin, and (c) drive the bladder-mounting pin to rotate in an opposite direction from that of the rolling pin.

A method for adjusting a printing apparatus, which the printing apparatus includes: a platen for supporting the medium, an imaging unit, a winding shaft for winding the medium, a shaft adjusting mechanism configured to adjust the position of the winding shaft, and a notifying unit configured to perform notification, comprising: a jig installing step for attaching one end of a strip-shaped jig, on which graduations are formed, to the winding shaft, and locking the jig to the platen, along a transporting path at both ends in a width direction of the medium, an imaging step for imaging the graduations by the imaging unit at two locations different from each other, in a direction orthogonal to a transport direction of the medium on the platen, a notifying step for notifying a result based on an image imaged by the imaging unit, and an adjusting step for adjusting the shaft adjusting mechanism.

The disclosure discloses a tape cartridge comprising a first tape roll, a second tape roll, a connecting part, and a pair of gripped parts. A first tape consumed by feed-out is wound around the first tape roll. The second tape roll winds a second tape around an axis extending along the first direction and provided on a downstream side of the first tape roll. The second tape is generated by a feeding of the first tape. The connecting part is provided so as to connect the first tape roll and the second tape roll. The pair of gripped parts extends along the second direction, each respectively provided on either side of the connecting part along the first direction. The gripped part comprises a slip preventing part configured to prevent slipping during gripping on an end of the gripped part in the one side along the second direction.

A winding machine (10) for winding and/or unwinding band-shaped or strip-like material (12) has at least one rotary plate (16), which is arranged on a pivot arm (24) and can be driven by means of at least two opposite coupling elements (20, 22), at least one coupling element (20) being associated with the rotary plate (16), and the rotary plate (16) being transferrable by means of a pivot device (30) between at least one decoupled state and at least one coupled state. Because the coupling elements (20, 22) can be positioned opposite one another in a coupling position in a sensor-based manner, this allows a coupling process which is as wear-free as possible.

A reversing reel includes a rotor, on which a reel mandrel with a rotary drive for winding strip into a coil is eccentrically arranged. A driven mandrel support device includes a mandrel support that has a bearing head for supporting a free end of the reel mandrel. The bearing head is movable with the reel mandrel when the reel mandrel is transferred from an initial-winding position into a final-winding position. The mandrel support is a first piston-cylinder arrangement, and the mandrel support is supported in a pivotable manner via a mandrel-support bearing on a slide that is movable tangentially to a circular path of the reel mandrel. The inclination of the mandrel support and the position of the bearing head are adjustable such that the mandrel support is oriented in accordance with a resultant force from the weight force of the coil and the tensile force on the strip.

A mandrel with a compensating segment, gripper bar, and external body segment making up a key piece configuration. The configuration adjusting the travel path of metal sheet being wound around the mandrel. The metal sheet thereby being wound without resulting imperfections which occur naturally when wrapping material around a cylinder.

A transport device unwinds a medium from a roll body to which a shaft member is mounted and transports the medium. The transport device includes an accommodation portion configured to accommodate the roll body, a main body portion to which the accommodation portion is mounted, and a roller pair configured to nip the medium. The accommodation portion and the main body portion are relatively movable. The main body portion includes a rack configured to engage with a gear of the shaft member. The rack is engaged with the gear when the accommodation portion moves relative to the main body portion to be pulled out of the main body portion.
