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 deployable device includes a supporting structure, a mandrel able to move in rotation with respect to the supporting structure about a first axis Z, a membrane able to pass from a rolled-up configuration rolled up around the mandrel about the first axis Z to a deployed configuration deployed along a second axis X substantially perpendicular to the first axis Z. The device comprises two fittings secured to the mandrel at their centre, arranged one on either side of the membrane and comprising first stubs on their periphery, a casing extending between the two fittings, the casing comprising second stubs of a shape complementing the shape of the first stubs, the casing being able to pass from a rolled-up configuration at least partially enveloping the membrane in the rolled-up configuration to a deployed configuration at least partially superposed on the membrane in the deployed configuration.

There is provided an image recording apparatus which is provided with a housing, a holder configured to be drawable from the housing, a supporting member supported by the holder and configured to support a sheet roll, a liquid container supported by the holder and configured to hold liquid, a conveyance mechanism arranged in an inner space of the housing and configured to convey a sheet unwound from the sheet roll, and a print head arranged in the inner space of the housing and configured to record an image on the sheet conveyed by the conveyance mechanism. The liquid container is configured to include at least one of tanks configured to hold liquid to be provided to the print head and a waste tank configured to pool liquid discharged from the print head.

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.

The present invention relates to a machine for producing multi-layer cardboard or paper, or a machine for either printing or converting, starting from a reel of paper, cardboard or other material. In general, the invention can be applied to machines wherein a reel of different materials is unwound and which requires a contrast system to regulate the tensioning of the ribbon. In particular, the invention relates to a system for braking said reel.

In particular, the invention relates to a braking system (2) for a support member (1) of a reel (B), for example, a reel of paper in a machine for producing cardboard or corrugated cardboard, wherein said braking system (2) comprises a motor-generator device (8) and a mechanical brake device (9) arranged coaxially.

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 magazine has a generally rectangular form of a frame. The frame has two spaced apart caps, at least one rail fixed to the caps so that the rail does not rotate, at least one tube rotatably connected between the caps and parallel to a rail, at least two finger assemblies upon a tube, a cutter that slides upon a rail, connectors and knobs upon each tube allowing it to rotate. The tube receiving a roll of wrapping paper upon its length and over the finger assemblies. The finger assemblies deflecting their fingers inside the roll. The connectors being of two severable components allowing detachment of a tube from a cap to receive a roll. The preferred embodiment has two rails and three tubes forming the frame.
