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 spool assembly configured to support a roll of material. The spool assembly comprises a first and second flange coupled together via a first and second arbor member. The first arbor member is slidably coupled within a first at least one slot of the first flange and slidably coupled within a second at least one slot of the second flange. A biasing member is coupled to the first arbor member such that the first arbor member is biased radially inward toward a longitudinal axis of the spool assembly. Rotation of the first flange relative to the second flange causes the first arbor member to translate within the first at least one slot and the second at least one slot causing a change in the arbor diameter.

A device for winding up a film at a packaging machine, the device including a reception mandrel drivable for rotation about a rotation axis and a reception sleeve for the film for being pushed onto the reception mandrel. The reception sleeve may be formed by segments arranged next to each other along a circumference or perimeter of the reception sleeve, wherein neighboring or adjacent segments may be pivotably connected to each other. The reception mandrel may be formed as rigid body having engagement structures that are configured to cooperate with shape features of an inner circumference or perimeter of the reception sleeve, when the reception sleeve has been pushed onto the reception mandrel, so that a rotation of the reception mandrel about the rotation axis causes the reception sleeve to rotate with the reception mandrel.

A roll medium holding device rotatably holds a roll medium. The roll medium holding device includes a medium positioning portion including an inclined surface that contacts an end of the roll medium and a medium holder that is swingable around an axis parallel to a rotation axis of the roll medium and movable in a radial direction of the roll medium. The medium holder presses an inner circumferential surface of the roll medium in a direction from the rotation axis of the roll medium toward the inner circumferential surface of the roll medium.

A tensioning mechanism includes a housing including an accommodation cavity and configured to be sleeved with a to-be-tensioned material, a tensioning assembly mounted in the accommodation cavity, and a driving assembly mounted on the housing and configured to drive the tensioning assembly to move against the housing, so that at least a part of the tensioning assembly protrudes from or retracts into the housing. The driving assembly includes a handle mounted on an outer side of the housing and configured to manually drive the tensioning assembly to move against the housing.

An edge tape cassette for receiving edge tapes comprising a cassette housing, in which a winding core is arranged, which fixedly holds an edge tape that is existent as a container in the form of a wound-up roll. Furthermore, the edge tape cassette additionally has a receiving element, which is rotatable mounted in the edge tape cassette, and to which the winding core is attached, in particular in a detachable manner.

A spool support, for supporting a windable material, comprises a main body, an actuator and a clamp portion. The actuator is movable relative to the main body between a first position and a second position. The clamp portion is pivotably connected to the main body. The actuator actuates the clamp portion such that the clamp portion pivots relative to the main body between a retracted position when the actuator is in the first position and a deployed position when the actuator is in the second position.

A tensioning mechanism includes a housing including an accommodation cavity and configured to be sleeved with a to-be-tensioned material, a tensioning assembly mounted in the accommodation cavity, and a driving assembly mounted on the housing and configured to drive the tensioning assembly to move against the housing, so that at least a part of the tensioning assembly protrudes from or retracts into the housing. The driving assembly includes a handle mounted on an outer side of the housing and configured to manually drive the tensioning assembly to move against the housing.
