A reinforced spool assembly has a shaft, a spool member coaxially mounted around the shaft, and two ratchets mounted on two axial ends of a combination of the shaft and the spool member. Each one of two ratchets has a body having an inner surface. The two inner surfaces of the two bodies face each other. In each one of the ratchets, the body has a reinforced supporting structure. The reinforced supporting structure is located between the shaft and the spool member and is offset from the inner surface of the body. A reference plane is defined on and extends along the inner surface of the body, is perpendicular to a central axis of the shaft, and passes through the reinforced supporting structure. Mechanical strength of the reinforced spool assembly is increased by the reinforced supporting structure.

A flange for use on a reel, a flange adapter, and a flange stand are provided. The flange may include an outer circumference, a hub assembly, and an arbor hole adapter that is adapted to engage an arbor hole to secure the flange to the reel. The arbor hole adapter may include an expandable portion that is movable between an extended position and a retracted position. First and second expansion plates may be coupled to the arbor hole adapter and connected by shoulder bolts that guide movement of the plates between an abutting configuration and a spaced-apart configuration, allowing movement of the expandable portion relative to the reel for modified engagement. The flange stand may include a base, a support portion, and a coupler for engaging a central extension of the flange to allow the flange to be supported in an upright position.

A thread storage apparatus includes a core around which thread is wound for storage. The core extends along an axial direction from a top end to a bottom end. The apparatus includes a top connector on the top end of the core, and a bottom connector on the bottom end of the core. The thread storage apparatus may be selectively attached to a first adjacent thread storage apparatus along the axial direction by connecting the top connector to a connector on the first adjacent thread storage apparatus. Similarly, the thread storage apparatus may be selectively attached to a second adjacent thread storage apparatus along the axial direction by connecting the bottom connector to a connector on the second adjacent thread storage apparatus. An assembly is formed by attaching several thread storage apparatuses in series. Adaptors are used to change between different characteristics of adjacent thread storage apparatuses in the assembly.

A tape dispensing system, including: a first roll cartridge including a hub with a first axial side and a second axial side opposite the first side; a first twist-lock connector integral with the first axial side of the hub a second twist-lock connector integral with the second axial side of the hub; a tape cutter extending radially from the hub; and a second roll cartridge substantially identical to the first roll cartridge, the first twist-lock connector of the second roll cartridge mates with the second twist lock connector of the first roll cartridge.

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.

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 roller accessory that allows a person to adapt a standard GaffGun™ tape roller to accept standard rolls of tape other than the tape the Gafftech company provides. The adapter includes a metal shaft with threads on one end that screw into the standard GaffGun™ assembly and threads on the opposite end to accept a threaded thumbnut that helps retain truncated cone members which in turn support a 2″, 3″ or other width of standard tape roll. The truncated cone members can be made of resilient material to frictionally grab the edges of the core of a standard tape role.

A coil feeding device and a graphic machine thereof are provided. The coil feeding device includes a roller mechanism for carrying a coiled material, a base mechanism, and a compression rod mechanism. The roller mechanism includes a shaft penetrating through the shaft hole and a tension structure disposed on the shaft. The tension structure includes a first sleeve, a second sleeve and a tapered fixing member. When the first sleeve and the second sleeve are fixed to each other, the tapered fixing member holds the shaft to achieve mutual fixation of the coiled material and the shaft. By providing the second sleeve, the first sleeve and the tapered fixing member that cooperate with each other, the coiled material and the shaft are fastened to each other quickly, thereby improving production efficiency. Through the base mechanism, the coil feeding device is directly used on existing graphic machine for material processing.

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.

The present invention relates to a holding system for holding sheet material for plotters characterized in that it comprises at least one substantially tubular side holding element (1), at least part of the external surface (2) thereof being tapered. Furthermore, said side holding element (1) comprises a longitudinal opening (7) and has internal chamfers at one of its ends (4). As a result of the thickness and the tapering of the external surface thereof, the side holding element hold the sheet material and, simultaneously, ensures that there is a gap between the winder tube and the sheet material wound on said tube, which facilitates its removal from the tube.
