A support spindle assembly for rotatably supporting a coreless paper roll for dispensing, the support spindle assembly including a spindle base, a spindle element having a central longitudinal axis (X) and having first and second ends, the spindle element being attached to the spindle base at the first end and rotationally fixed in relation to the spindle base and a rotatable sleeve rotatably disposed about the spindle element, and rotatable in relation to the spindle base and to the spindle element. The support spindle assembly includes a resilient member disposed about the first end of the spindle element, which resilient member is arranged to cooperate with the spindle base and with the rotatable sleeve in order to provide the rotatable sleeve with a rotational resistance.

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 dispensing system includes a roll comprising a keyed end, a dispenser comprising a housing for receiving the roll, and a mount comprising a roll holder to support the keyed end and a roll support to support an opposing end. The roll holder comprises a frame, a clutch plate, a spindle, and a biasing unit, the clutch plate being disposed adjacent the spindle, and the spindle receives the keyed end and is rotatably coupled to the frame to permit rotation of the roll and the clutch plate about the dispensing axis. The spindle comprises a clutch surface and translates along the dispensing axis, and the biasing unit biases the spindle along the dispensing axis away from the frame. Mounting the keyed end of the roll onto the mount pushes the spindle towards the frame to increase a normal force between the clutch plate and the clutch surface.

A tape dispenser having a handle, a base plate disposed at an end of the handle, a rotatable tape mount engaged on the base plate, a nose member disposed on the base plate, a cylinder rotatably engaged on the nose member near a cutter and a guide element is provided. The guide member is slidingly engaged on the base plate. The guide element is adjustable between a loading position which is slid rearward ly to provide space between a tape engaging end of the guide element and the nose member and a loaded position where the end of the guide element is located adjacent the nose member. A tape core support assembly can include a shaft secured to the frame and an axle assembly disposed about at least a portion of the shaft. The axle assembly includes a hub having an outer surface and at least three arcuate arms extending outwardly from the hub outer surface. An outer periphery of the arms forms a theoretical or actual cylinder configured to receive the tape core. The rotatable tape core support can include a stationary axle, a spring inclusive bushing mounted to said axle, and a rotatable tape mount. The rotatable tape mount can include a housing that receives the bushing such that the spring engages a surface of the housing to control rotation of the tape mount.

Refill for a dispenser, with a material web wound to form a roll and at least one substantially axially adjustable bearing journal. The at least one substantially axially adjustable bearing journal is adjustable substantially axially outwards away from the roll starting from a defined inner end position in which it protrudes axially beyond the roll. A bearing unit for such a refill, and a dispenser for housing the refill and dispensing the material web are also provided.

A roll accommodation unit includes: a roll support shaft; a pair of side walls; and a pair of roll bearings that are attached to the pair of side walls, recessed portions are formed at upper ends of the pair of side walls, the pair of rolling bearings are attached to the side walls at positions corresponding to bottoms of the recessed portions such that the rolling bearings project upward beyond inclined surfaces of the recessed portions, the roll support shaft includes a support shaft main body, and a pair of small-diameter portions that are provided at both ends of the support shaft main body, and the roll support shaft is supported with the small-diameter portions abutting on outer circumferential surfaces of the pairs of rolling bearings in a state in which the support shaft main body is located at an interval from the recessed portions.

A web roll handling and loading system and methods employ hubs positioned on opposing sides of a roll of web material wound on a hollow tubular core. Hub faces have an annular shape configured to be seated in respective ends of the hollow tubular core. The hubs are pivotably supported for pivoting between an operational position and a deflected position. The roll of web material is loaded on the hubs by lifting it from beneath the hubs to deflect the hub faces arcuately upward, then lowering the roll to allow the hub faces to pivot downward and become seated in the ends of the hollow tubular core. Alternatively, the roll is loaded into a pick-up tool by lowering the pick-up tool downward to the roll so the hubs deflect arcuately upward, then raising the tool so the hubs pivot downward and become seated in the hollow tubular core.

An anti-misuse system for a sheet dispenser having a roll of sheet material and a housing to receive the roll. The anti-misuse system includes an end portion of a roll incorporating a first projection and a corresponding end wall portion of the housing comprising a retracting portion incorporating an interacting mechanism. The retracting portion is movable between a deployed position in which the interacting mechanism affects the functionality of the sheet dispenser and a retracted position in which the interacting mechanism enables the sheet dispenser to be functional. The retracting portion further incorporates an abutment drivable by the projection upon insertion of the roll into the housing to move the retracting portion into the retracted position.

A roll accommodation unit includes: a roll support shaft; a pair of side walls; and a pair of roll bearings that are attached to the pair of side walls, recessed portions are formed at upper ends of the pair of side walls, the pair of rolling bearings are attached to the side walls at positions corresponding to bottoms of the recessed portions such that the rolling bearings project upward beyond inclined surfaces of the recessed portions, the roll support shaft includes a support shaft main body, and a pair of small-diameter portions that are provided at both ends of the support shaft main body, and the roll support shaft is supported with the small-diameter portions abutting on outer circumferential surfaces of the pairs of rolling bearings in a state in which the support shaft main body is located at an interval from the recessed portions.

A tension-inducing shaft system includes a shaft, two shaft caps, and a biasing mechanism. A bore extends through the shaft between two ends of the shaft. The shaft caps are positioned on the two ends of the shaft. Each shaft cap includes a collar having a size that is larger than the bore, a keyed end, and an anchor. The biasing mechanism is arranged inside the bore and is coupled to the anchors of the shaft caps so that the biasing mechanism exerts inward forces on the shaft cap. The keyed ends of the shaft caps can be coupled to a housing so that the shaft caps do not rotate with respect to the housing. The shaft is configured to rotate with respect to the shaft caps such that, when the keyed ends are coupled to the housing, the shaft is capable of rotating with respect to the housing.
