A roll holder is inserted with a hollow tube of one of a first roll having a first inner diameter and a second roll having a second inner diameter greater than the first inner diameter. The roll holder includes a holder and a cam assembly that are supported by a support shaft and movable in an axial direction of the support shaft. The cam assembly includes an abutment and a cam. The abutment contacts a lateral end of the second roll in the axial direction of the support shaft. The cam presses against one of a first presser and a second presser of the holder in a radial direction of the support shaft to cause the one of the first presser and the second presser to press against and hold an inner circumferential face of the hollow tube of the one of the first roll and the second roll.

The present invention relates to a mandrel comprising a radially movable portion (6, 8) and a retaining device for a sleeve (7) having an annular cross-section. Said device comprises a mounting (14), inserted in or built into the mandrel, and a retaining tab (1) pivotably mounted around an axis (3) that is in a direction parallel to the axis of the mandrel and onto said mounting (14). Said retaining tab (1) is designed to be, during use, pivotable from a first position, in which said retaining tab covers a portion of the annular surface of the sleeve (7), toward a second position, in which said retaining tab releases the annular surface of the sleeve (7). The pivotal movement from the first position toward the second position, or vice versa, is, during use, automatically actuated by radially moving the movable portion (6, 8) of the mandrel.

The present invention refers to the apparatus for storage and dispensing foil from the roll, and also to the wall attachment for placement of multiple dispensers in vertical dispenser system for rolled materials, where two side walls and one back wall of dispenser's body, perpendicular to the floor, enclose the storage space for the material from three sides, while fixedly attached cutting assembly provides the fourth wall. The elongated slot located close to the back wall in the floor of the dispenser base interacts with gravitationally working pivoting latch of the mounting wall frame in the vertical dispenser system to secure placement of installed apparatus on the wall frame. Top rotatable attached to the side walls of the container, while lifted from horizontal position by handle tab, reveals the free end of foil on top of the shroud that remains ready for picking and pulling from the roll in container anytime the top is lifted from horizontal position and then cut by pulling farther the unwound foil while bottom edge of top's body tab pushes foil below the cutting blade, and also frictionally holds the foil between shroud and top's body tab, therefore the foil, pulled farther, engages with serration of the cutting blade due to the intervening position of the said blade in relation to pulling direction.

A cable reel that has at least one support frame having an outwardly extending braking gear member and a first flange having a central opening with an internal braking gear member engaging the outwardly extending gear member of the frame, thereby rotatably coupling the at least one support frame and the first flange. A hub is provided between the first flange and a second flange that opposes the first flange. The hub is configured to support cable, wherein the engagement of the gear members provides friction for cable payoff from the hub.

A method of installing cable on a cable reel that has the steps of providing a cable reel that includes first and second opposing flanges where the first flange has a first hub portion and the second flange having a second hub portion and the first hub portion has one or more flexible segments; placing a cable coil over the first hub portion and on the first flange so that the first hub portion substantially extends through an inner diameter of the cable coil; and expanding the one or more flexible segments by inserting the second hub portion inside of the first hub portion so that the one or more flexible segments engage the cable coil.

Embodiments of the present invention describe a spindle for use by rolled materials (for example, ribbon, and labels) in a thermal printing device. The spindle contains a rigid side designed to prevent the spindle from flexing during printing. The spindle also contains a flexible side designed to address tolerance issues with the core of the rolled material and to retain the relative movement of the core of the rolled material.

A cable reel that has at least one support frame having an outwardly extending braking gear member, the outwardly extending gear member being located off-center on the frame; a first flange having a central opening and a first hub portion surrounding the central opening, the central opening having an internal braking gear member engaging the outwardly extending gear member of the frame, thereby rotatably coupling the at least one support frame and the first flange; and a second flange opposing the first flange, the second flange having a second hub portion, the first and second hub portions being configured to mate with one another to support cable, wherein the engagement of the gear members providing a friction for cable payoff.

A method of installing cable on a cable reel that has the steps of providing a cable reel that includes first and second opposing flanges, the first flange having a first hub portion and the second flange having a second hub portion, the first hub portion being longer than the second hub portion, the first hub portion having a plurality of flexible segments; placing a cable coil over the first hub portion and on the first flange so that the first hub portion extends through the cable coil; and inserting the second hub portion inside of the first hub portion, thereby expanding the flexible segments so that flexible segments engage the cable coil.

A delivery reel for an elongated sheet, having a disk-shaped flange member on which a sheet roll is positioned; an auxiliary core member of generally cylindrical shape split in the circumferential direction to enable expansion in diameter, and inserted into the inside diameter part of the sheet roll; a main core member fitted into the auxiliary core member which has been inserted into the sheet roll; and a stopper member attached to the circumferential edge of the flange member, and jutting toward the outside in the radial direction. The main core member has a plate spring. In a state in which the auxiliary core member has been inserted into the inside diameter part of the sheet roll, and the main core member has been fitted into the auxiliary core member, the plate spring presses the inside peripheral surface of the auxiliary core member toward the outside in the radial direction.

A cable reel that has first and second opposing flanges. The first flange has a first hub portion and the second flange has a second hub portion. The first and second hub portions are axial aligned and configured to mate with one another to support cable. The first hub portion includes an elongated wall extends from the first flange. The elongated wall is sized to support cable. The elongated wall defines an inner area that is configured to accept the second hub portion. The elongated wall includes a plurality of flexible segments. The second hub portion includes a truncated wall that is receivable in the inner area of the first hub portion. The truncated wall includes a tapered outer surface for engaging and expanding the plurality of flexible segments.
