Abstract: A roll medium supporting apparatus includes: a base body portion to be inserted into a hollow shaft portion of a rolled medium; a plurality of contact supporting portions provided circumferentially of the base body portion so as to be capable of being displaced radially of the hollow shaft portion, having a plurality of predetermined positions within the displaceable range, and coming into contact with the inner peripheral surface of the hollow shaft portion and supporting the same; and a stabilizing mechanism configured to stabilize the contact supporting portions at the plurality of predetermined positions.

Abstract: A tape printer includes a roll sheet holder storage part of which a bottom is formed with a positioning recess which is rectangular in plan view and long sideways and has a predetermined depth. A discrimination recess rectangular in plan view is provided between the positioning recess and an inner base end of a holder support member). The discrimination recess fittingly receives a sheet discrimination part extending in a predetermined length from a lower end of the positioning holding member inward at substantially right angle thereto. The sheet discrimination part is formed with sensor holes arranged in an L-shaped pattern. In the discrimination recess, there are provided sheet discrimination sensors arranged in an L-shaped pattern.

Abstract: In one embodiment, a take up reel comprises a core having a generally open interior and an outer surface that is adapted to hold a sheet-like material that is wound around the core. Also, the core defines at least one slot. A slider member is slidable within the slot between a home position and an extended position away from the outer surface. In this way, when the sheet-like material is wound around the outer surface of the core when the slider member is in the extended position, the sheet-like material is spaced apart from the core in the region of the slot. Further, when the slider member is moved to the home position, the tension in the wound sheet-like material is reduced to facilitate removal of the core.

Abstract: A take up roller for use in a continuous roll towel cabinet is shown which can after taking up the desired amount of toweling, be simply collapsed to have a smaller daimeter facilitating easy removel from the center of the accumulated toweling. A three segment cylinder is shown with a pair of end spindles that serve as the central shaft and expanding/collapsing member.

Abstract: A fiber optic cable winding tool having a disk-shaped base with a central axis, and four quarter-circle spools. Each spool has a fiber optic cable contacting surface with a radius of curvature exceeding a minimum bend radius of the fiber optic cable. The tool further includes four radial guides connected to the disk-shaped base for slidably mounting the four spools on the disk-shaped base such that the spools are radially adjustable relative to the central axis of the disk-shaped base. A resilient ring inwardly biases the spools on the radial guides towards the central axis of the disk-shaped base. A moveable wedge-shaped disk engages the spools to permit the spools to be radially adjustable relative to the central axis of the disk-shaped base. The radial guides permit the spools to be radially collapsed towards the central axis of the disk-shaped base after winding the fiber optic cable to permit removal of the fiber optic cable from the spools.

Abstract: A web processing apparatus has a cutting mechanism for cutting elongate webs of different widths from a raw web, a core rotating mechanism for selectively holding cores having different diameters and different axial lengths and rotating a selected one of the cores in opposite directions, a winding mechanism for supporting one of the elongate webs on an outer circumferential surface of the core to wind the elongate web in different winding directions when the core is rotated, and a cutting mechanism for cutting an end of the elongate web to produce a roll after the elongate web is wound around the core.

Abstract: At least two pairs of carrier arms are mounted to a rotary shaft for independent travel axially thereof while being constrained to joint rotation therewith. Each pair of carrier arms are disposed opposite each other axially of the shaft for rotatably holding one web roll therebetween via expansion chucks. An internally screw-threaded sleeve is rotatably mounted to each carrier arm and locked against axial displacement relative to the carrier arm. Rotatably supported on the shaft and extending parallel to its axis, a screw-threaded rod extends through, and is threadedly engaged with, the sleeves on each pair of carrier arms. A reversible electric motor is drivingly coupled to each threaded nut, and an additional similar motor to each threaded rod.
