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.

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.

A medium supporting device including a support part configured to support a roll body on which a sheet shaped medium is wound, a shaft serving as a rotary axis of the roll body and secured with the support part, and a driver configured to rotate the roll body supported by the support part. The shaft is secured to the support part by using a metal plate having a flat surface provided with an insertion hole, the insertion hole being a hole into which the shaft is inserted. An outer circumference part of the metal plate is restricted from moving in a rotation direction of the roll body relative to an inner circumference part of the support part.

An unpowered, manually operable apparatus for dispensing cushioning wrap material drawn concurrently from a roll of separator material and a self-contained cartridge that includes a roll of expandable sheet material. The rolls are supported on a stand for rotation about respective parallel, spaced-apart axes. In addition to the roll, the cartridge includes a tensioning assembly and support panels that abut respective ends of the roll. The tensioning assembly and the support panels cooperate with the stand to control rotational resistance of the roll. The rotational resistance causes the expandable sheet material to expand in length and thickness as it is manually pulled from the stand with the separator material, and support surfaces on the stand hold the cartridge and the separator roll in position. When the cartridge containing the expandable sheet material is depleted, the cartridge is readily removed and replaced.

A printer includes: a container configured to contain a roll into which a belt-shaped print medium is wound, the roll being inserted through an opening; a guide configured to guide the roll, the guide being disposed in the container and having a pair of abutting faces that abut on both side faces of the roll; a holding part that is movable between a first position where the holding part protrudes inwardly from the abutting face and a second position where the holding part does not protrude inwardly from the abutting face, the holding part being biased from the second position to the first position and holding the roll rotatably at the first position; and a displacement part configured to be displaced with motion of the holding part. At least a portion of the displacement part is exposed when a user sees the displacement part through the opening, such that the displacement part is recognizably displaced in a different position depending on whether the holding part is at the first position or at the second position.

A rewinding machine winds a web material into a log about a core. The web material to be wound is directed about a rotating winding drum. A continuous loop is spaced from the winding drum and with the winding drum defines a nip through which the core is inserted and through which the web material is directed. A surface of the continuous loop opposite the winding drum across the nip is configured to move in a direction generally opposite of the winding drum for winding the web material about the core. A rider roll defines a winding space with the winding drum and the continuous loop. The rider roll is movable relative to the continuous loop and the winding drum to allow for an increase in a diameter of the log in the winding space during winding of the web material about the core.

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 core chuck system (10) comprising a core chuck (11) and a spindle (12) onto which the core chuck (11) is lockable, which core chuck system (10) comprises a ball locking mechanism, a locking button (15) and a cone connection (C).

There is provided a print apparatus and a media roll for the print apparatus, comprising a media identifier located on an end of a core section of the media roll. A type of media loaded into the print apparatus is determined by sensing the media identifier on the media roll using a non-contact sensor to scan the end of the core section.

A manually-operated dunnage conversion apparatus includes a housing, a support mounted in the housing and configured to support a supply of sheet material for dispensing from the dunnage conversion apparatus, and one or both of (a) a guide member mounted in the housing downstream of the support and providing a resilient surface across which the sheet material may be drawn to restrict tearing of the sheet material as it is drawn from the dunnage conversion apparatus, and (b) a tensioning assembly mounted in the housing and configured to apply a compressive force between opposite axial sides of the housing to control the force necessary to dispense the supply of sheet material. Except for the tensioning assembly, the apparatus may be made of paper-based products, making the apparatus recyclable, reusable, and composed of a renewable resource, as well as inexpensive to manufacture.
