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 belt replacement device may include: a base portion having a belt placed thereon, the belt being wound in a roll shape; a rotating portion mounted on the base portion, and rotating the belt wound in a roll shape; a transporting portion holding and transporting the belt passed through the rotating portion; a guide portion guiding the belt discharged through the transporting portion; and a loading portion to which the belt dropped from the guide portion is loaded, and the belt replacement device can improve winding workability for the belt.

A dispenser having a feed roller that at least partially engages sheet material to facilitate dispensing thereof, and a cutting mechanism disposed within a chamber defined by a body of the feed roller. The cutting mechanism including a cutting blade and at least one movable support connected thereto. The at least one support further is operatively connected to the body of the feed roller and is actuated with rotation thereof to move the cutting blade into and out from one or more openings defined along the body of the feed roller to at least partially cut or perforate a selected portion of the sheet material as the sheet material is dispensed.

A dispenser for dispensing a flexible, rolled sheet material can include a housing and a supply of the sheet material supported within the housing for feeding the sheet material along a path defined through the housing. A feed roller can be rotatably mounted within the housing and have a body that engages the sheet material to pull the sheet material from the supply to dispense a selected amount of the sheet material therefrom. The dispenser also can include pressing rollers positioned adjacent the feed roller and biased to engage the sheet material between the pressing rollers and the feed roller, and a cutting mechanism arranged along the body of the feed roller that can have a cutting blade operatively connected to the body of the feed roller and actuated with rotation thereof to at least partially cut or perforate a selected portion of the sheet material.

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.

A wrapping or roll-up device including a base, one or more connectors, an arm, and a handle. In embodiments, one or more connectors are connected to the base and are configured to connect the device to a wall or support structure, and/or the arm includes an aperture. In embodiments, a handle includes an extended portion and a grip portion, and at least a portion of the extended portion is configured to extend through the aperture. Further, with embodiments, the extended portion includes a slot disposed about an end of the extended portion. Embodiments may include a tensioner. Methods for wrapping or rolling up an article such as a wrap are also disclosed.

Spindles and cover assemblies for dispensing sheet product for use with coreless sheet product rolls. The spindle may include a hollow cylindrical body, which may have an elongated channel in a sidewall; a rod which extends partially out of the body; and a spring disposed within the body in biasing contact with the rod. The rod may include a flexible tab matingly engaged within the channel, permitting the rod to translate within the hollow cylindrical body without falling out. The hollow cylindrical body may have an end with an opening bounded by an inward facing ledge, and the rod may include a radial ledge, such that the rod can translate within the body but cannot fall out due to interference between the inward facing ledge and the radial ledge. The spindle may include a friction hub disposed about and rotatable around the hollow cylindrical body between ends of the body.

In a medium supply device, a receiving portion includes a support portion configured to rotatably support a spindle, and a drive gear meshing with a driven gear provided at the spindle to rotate the spindle, and a displacement member includes a pivoting shaft configured to pivot between an advanced position where the spindle is covered and a retracted position where the spindle is exposed, an abutting portion abutting the spindle when the spindle is installed at the receiving portion, the abutting portion being configured to cause the displacement member to pivot to the advanced position, an opposing portion abutting, at the advanced position, an outer peripheral surface of the spindle installed at the receiving portion, a cover portion configured to cover the driven gear, and a grounding member contacting the spindle, thereby coupling to a ground potential.

A dispenser having a feed roller that at least partially engages sheet material to facilitate dispensing thereof, and a cutting mechanism disposed within a chamber defined by a body of the feed roller. The cutting mechanism including a cutting blade and at least one movable support connected thereto. The at least one support further is operatively connected to the body of the feed roller and is actuated with rotation thereof to move the cutting blade into and out from one or more openings defined along the body of the feed roller to at least partially cut or perforate a selected portion of the sheet material as the sheet material is dispensed.

A foil reel mounting device for supporting a reel of stamping foil in a supporting module. The device includes a support having a recess to receive an axle of the reel of stamping foil. A retaining element mounted on the support and arranged to move between a closed position, in which the retaining element retains the axle of the reel in the recess, and an open position, in which the retaining element releases the axle of the reel from the recess. The retaining element is biased towards the closed position. Also, a supporting module has at least one foil reel mounting device and a stamping machine includes a supporting module or at least one foil reel mounting device. A method for loading and unloading a reel of stamping foil with such at least one foil reel mounting device is also disclosed.
