Abstract: Adapters according to the invention are configured for solid or coreless rolls of material dispensed in a roll dispenser. The dispenser has slots defined on the side walls thereof along which the adapters move. The adapters include a carriage having opposite side members attached to a transverse support arm. A pin is disposed on the outboard surface of each side member and engages in the slots defined in the dispenser side walls. A protrusion is disposed on an inboard surface of each side member and engages at least partially into a recess or divot formed in the sides of the solid or coreless roll.

Abstract: A dispenser for holding and dispensing sheets of paper from paper rolled on a tubular core, including a base member by which the dispenser may be attached to a wall and first and second rigid support arms at each end of the base member providing a pair of inclined openings extending upwardly from the base when the base is mounted on a vertical wall. A spindle member is insertable through the tubular core on which the paper is rolled. Opposite ends of the spindle are receivable in a corresponding one of the inclined openings allowing the spindle and rolled paper to move by gravity against the base member but permitting sheets of paper to be dispensed therefrom.

Abstract: A balloon tying system including a plate portion having a pair of upper apertures and a pair of lower apertures therethrough. The plate portion includes an upper strap portion extending between the pair of upper apertures thereof. The upper strap portion secures the plate portion to the helium tank. A hook portion is secured to the plate portion. The hook portion is defined by an upper linear segment and a lower arcuate segment. The lower arcuate segment has an upper aperture and a lower aperture therein in communication with an internal common channel.

Abstract: A roller type support frame structure includes a body connected to a post. Two end pieces respectively extend from the body and one of the end piece has a threaded hole and the other end piece has a hole defined therethrough. A core has a threaded outside for being threadedly engaged with the threaded hole, and an insertion section of the core is inserted into the hole of the second end piece. A sleeve is rotatably mounted to the core.

Abstract: An adjustable width rolled paper dispenser having a central adjustable locking rod captured between a pair of adjustable side brackets contained in the mounting base, the side brackets having locking channels to capture and secure the slotted ends of the adjustable locking rod, preventing the displacement of the adjustable locking rod from the side brackets when dispensing a segment of the rolled paper.

Abstract: A carriage unit adapter for solid or coreless rolls of paper material that are dispensed in a roll dispenser having slots defined on inner surfaces of side wall members thereof for receipt of said adapter and a back wall positioned a distance from the slots that Is sightly greater than the radius of a solid or coreless roll. The carriage unit adapter includes: a pair of spaced apart arms joined by a connecting member having a front surface and a back surface, each arm having an outboard surface and an inboard surface including: (i) an outboard pin disposed on the outboard surface, the outboard pin configured to slidably engage a slot on an inner surface of a side Wall member of the dispenser; and (ii) an inboard pin attached to the inboard surface, the inboard pin configured to engage a coreless roll of material.

Abstract: The invention relates to a method and a device for correcting the bending of a shaft (2), an axle or another carrier resting with both ends upon a pair of bearing elements (6, 7). The carrier bends under its own weight and/or additional loading and/or due to forces applied on the bearing elements. Said bearing elements are submitted to a bending counterforce (4) produced using the carrier weight and/or additional loading and/or forces applied.

Abstract: A winding device, having a winding shaft, which can be inserted into and removed from the winding device, and a winding element and bearing journals protruding from both ends in the direction of the center axis of the winding shaft. The winding device has two outer bearings for receiving the bearing journals for rotatable seating of the winding shaft in the winding device, and an additional bearing for the winding shaft is assigned, spaced apart, to each outer bearing. Each outer bearing has a coupling device, and the coupling devices are displaceable along the center axis of the winding shaft and can be connected with or disconnected from the respective ends of the bearing journals. The additional bearings, acting as inner bearings, are formed between the ends of the bearing journals, which can be connected with the outer bearings, and the winding element on the bearing journal of the winding shaft.

Abstract: An image forming device includes a roll tensioner adapted to hold a medium roll rotatably mounted thereon for providing a printable medium strip to the imaging device. The roll tensioner comprises a torsion mechanism exerting torsion to the printable medium strip that tends to pull back the printable medium strip and, thus, to prevent slack of the printable medium strip, the roll tensioner further including a torsion control mechanism to prevent the torsion from getting too large to stop the rotation of the printable medium roll, the roll tensioner also including a clutch mechanism to prevent damage to the torsion mechanism.

Abstract: A device for dispensing and carrying tape having a C-shaped handle where both ends have openings. Two cylinders inserted through each of the openings form a spindle by which to dispense and carry tape. Each cylinder has a J-slot cut into its side to receive an engaging screw which attaches through the C-shaped handle. By turning each cylinder one way, the cylinders form a spindle by which to hold a roll of warning (or caution) tape. By turning the cylinder each the other way, the cylinders retract to allow installation of a new warning tape roll.

Abstract: A rolled sheet material dispenser and holder that allows one to tear off a single sheet at a time without unrolling unwanted sheets. The apparatus is designed so that the moment of inertia of the core element and paper roll are sufficient to retard excessive spooling when a sheet is torn off the roll.

Abstract: A dispenser assembly for dispensing product arranged in a roll and the roll has a cavity disposed at each end of the roll. The dispenser assembly includes a base, a pair of arms having first and second ends and at least one roller associating with the second end of the respective arm. The first end of each arm attaches to the base and each second end extends outwardly from the base. The roller has a roll engaging portion which is structured and arranged to extend from the second end into the respective cavity of the roll when the roll is inserted into the arms.
