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

According to an example, a media roll support may comprise a sliding element movable along a guide, a hub to receive the media roll and a coupling plate. The hub may comprise an elastic element biased towards a first side of the media roll. The coupling plate may be attached to the hub and to the sliding element. Upon holding the media roll, a deformation of the elastic element may tilt the sliding element. The tilting of the sliding element may lock the sliding element movement, thereby preventing its movement.

A dispenser for dispensing plastic film for vehicle repair, the dispenser including: a first support adapted to rotatably support a roll of plastic film, and an aperture, wherein the plastic film can be pulled through the aperture from the roll and retracted through the aperture towards the roll.

A holding system and methods, systems, and apparatuses for constructing, assembling, and using the holding system are disclosed. The holding system can include an arbor bushing. The arbor bushing can include a head portion. The holding system can also include a plate attached to the arbor bushing. A pad can be attached to the plate. The head portion of the arbor bushing extends outward beyond a surface of the pad.

A cutter unit includes a first frame, a fixed blade, a movable blade, a movable blade drive mechanism and a pressure mechanism. The fixed blade has a first cutting edge portion. One end portion of the movable blade has one end configured to cut a cut item in cooperation with the first cutting edge portion. The second cutting edge portion and the first cutting edge portion contacting with each other at a first point and a second point. Another end portion of the movable blade has a contacting portion in contact with the first frame at a third point. The first point, the second point and the third point define an imaginary triangle. The pressure member presses the movable blade at a pressure contact position so that the movable blade presses against the fixed blade. The pressure contact position is positioned substantially within the imaginary triangle.

An electric stretch film dispenser includes a frame and a power unit. The frame has a top seat and a bottom seat. The top seat and the bottom seat are jointly provided with a film mounting unit and a film dispensing unit. The film dispensing unit has a first roller and a second roller. The first roller is connected with a first power drive unit. The first power drive unit is configured to drive the first roller to rotate. When in use, the film of a film roll is pulled due to different rotational speeds of the first roller and the second roller. Thereby, the electric stretch film dispenser can automatically generate tension when used, so it can be used to pack articles at different heights. The electric stretch film dispenser facilitates the application of the film and increases the tension of the film.

A paper dispenser includes a paper input area and a paper output area; the paper input area including a holder for a paper roll and including a paper input unit provided to displace paper from the paper roll towards the paper output area, the paper output area including a paper output unit which is adapted to dispense paper to an outside of the dispenser, the dispenser further including a paper cutting unit arranged between the paper input unit and a paper output unit, which paper cutting unit is adapted for cutting the paper, wherein the paper output unit is operationally connected to the paper input unit to dispense the paper at a dispensing speed that is at least as large as a displacing speed of the paper input unit.

The present disclosure relates to a tape dispenser for dispensing tape from a tape roll received therein. In one embodiment, the tape dispenser comprises a main body with a mandrel adapted to receive and releasably retain a tape roll, and wherein the mandrel allows rotation of the tape roll about a mandrel axis. It further includes a cutting arm comprising a blade attached to the main body for cutting the tape and positioned at a distance from the mandrel axis. The tape dispenser further includes an attachment unit for temporarily and releasably attaching the tape dispenser to a furniture, wherein the main body is pivotably attached to the attachment unit, and wherein a pivot axis is perpendicular to a mandrel axis.

The unwinder includes a pair of tailstocks adapted to engage and support a reel to be unwound and a peripheral unwinding device adapted to coact with a reel in the unwinding station. There is also provided a shuttle adapted to insert reels into the unwinding station, movable between a loading position of the reel on the shuttle and a position aligned with the pair of tailstocks, to transfer a reel from the shuttle to the tailstocks or vice versa. In use, the peripheral unwinding device is positioned under the reel of web material, so that the force exerted by the peripheral unwinding device on the reel being unwound has a component that is subtracted from the weight force of the reel.

The splicing device for splicing a trailing edge of a first web material to a leading edge of a second web material includes members defining a feed path of the web material. The device also includes a first cutting member and a second cutting member, cooperating with the first cutting member. One of the two cutting members is provided with a movement transverse to the feed path of the web material, to move the cutting member from an operating position, in which it is in front of the other cutting member, to an idle position, withdrawn with respect to the feed path of the web material.
