Abstract: A cable reel for retaining a continuous length of cable is preferably constructed using an inexpensive plastic material, such as corrugated plastic. In one embodiment, the cable reel includes a hollow tubular core with a set of outward radial tabs integrally formed at each of its ends. A single, disc-shaped, interior support flange is mounted within the interior of the core in circumferential contact therewith to provide structural rigidity. Additionally, on each end of the core, an annular inner flange and a disc-shaped outer flange are disposed in coaxial alignment with one another against opposing surfaces of its corresponding set of radial tabs and are fixedly secured together as part of the assembly process. The multi-flange construction enables the thickness, diameter and/or material properties of the ends of the cable reel to be adjusted, as needed, to accommodate the strength and dimensional requirements of the intended application.

Abstract: A dual-bearing reel includes a reel body and a spool. The reel body includes a first body part, a second body part, and a thumb rest. The spool is rotatably disposed between the first body part and the second body part. The spool includes a bobbin trunk, a first flange, and a second flange. The first flange is on a first body part side of the bobbin trunk, and has a smaller diameter than the first body part. The second flange is on a second body part side of the bobbin trunk, and has a smaller diameter than the second body part. The first body part includes a cutout part on an outer edge of the first body part. The cutout part is adjacent to the thumb rest and to an outer edge of the first flange of the spool.

Abstract: A reel system includes a reel having a rotational axis, the reel including a plurality of ledges spaced radially from the rotational axis, the ledges defining a stepped configuration along an interior surface of the reel. The reel system also includes a first clamp having a first width and a second clamp having a second width greater than the first width, wherein the first clamp and the second clamp engage the plurality of ledges as the reel is rotated.

Abstract: A spool assembly has a central cylindrical barrel or tube portion formed from a substantially rectangular planar material, such as thin-gauge sheet aluminum or tin-plated steel, with beveled corners. The formation of the barrel from the substantially rectangular planar material results in a seam with shallow V-notches of the seams at the opposite ends of the barrel. A circular flange sub assembly is attached to each end of the barrel and extends radially outwardly perpendicular to the longitudinal axis of the barrel. Each flange sub assembly comprises an outer flange and an inner flange core joined by an annular ring or curl that defines a circular hub recess or cavity for receiving the respective end of the barrel. A portion of the seam at the end of the barrel is secured within the circular hub recess or cavity; whereby the flanges are keyed onto the ends of the barrel, thereby preventing circumferential slippage of the flanges on the barrel.

Abstract: A bobbin (1) of plastic has a cylinder (2) and, formed integrally therewith, circumferential end flanges (3) and is made of a U-shaped channel. Each end flange (3) consists of a plurality of spaced-apart, essentially radial flange elements (4) which are distributed along the circumference of the cylinder (2). In a method of manufacturing such a bobbin, a U-shaped channel is made by injection moulding. The U shaped channel is given such a shape that its side walls consist of a plurality of spaced-apart wall elements which are distributed along the length of the channel. The channel is bent to form the cylinder (2) and its ends are connected with each other in this bent position.

Abstract: A pair of flanges (12, 12) which have through-holes (17) for a rotating shaft, and a shaft part which connects the central parts of these flanges (12, 12) at a specified spacing, are formed from cardboard plates; furthermore, the above-mentioned shaft part is formed so that this shaft part is foldable. For example, flaps (13) which extend in the radial direction, and which have base ends (13a) on the side of the central part of the corresponding flange (12) are formed by stamping in each of the pair of flanges (12, 12) and slits (14) which extend in the circumferential direction of each flange (12) are formed on a circle that is concentric with the flange (12), and which includes the base ends (13a) of the flaps (13). The flaps (13) of the respective flanges (12) are pulled into upright positions, and the projecting parts (13b) of the flaps (13) of one of the flanges (12) are inserted into the slits (14) of the other flange (12), thus fastening the flanges (12) to each other, so that a reel (11) is formed.

Abstract: A method of fabricating paperboard cores, and the paperboard cores so fabricated, have improved chuck strength and can be used with chucks rotating at a speed of at least 200 mm/min., even with paper rolls having a weight of over 8.5 tons. A plurality of paperboard plies (e.g. made by press drying) are wound spirally around a mandrel into a tube to produce a paperboard core having a cylindrical surface and inside diameter and a wall thickness of 10 mm or more.

Abstract: A spool sleeve consisting of several interconnected layers formed by webs, wherein a recess in an inner layer contains an appropriately shaped transponder having a weight that is approximately equal to that of the web material removed to create the recess so that any imbalance of the sleeve with the transponder therein embedded is avoided.

Abstract: A spool for fishing line comprises: a short-cylinder core portion; and a pair of flange portions provided at opposite end portions of the core portion, and the core portion and the flange portions are made of paper.

Abstract: Composite paperboard container constructions, providing optimized axial crush strength, and related properties, are formed of one, two, or three structural paperboard plies that are arranged to form a layered body wall having a cross-section of the construction in the ordered structure, high compression strength paperboard layer\low compression strength paperboard layer\high compression strength paperboard layer. Preferably, the container body is formed of one or two structural plies and at least one structural ply is a multiple layer paperboard having both high compression strength and low compression strength paperboard layers.

Abstract: A high torque capacity metal spool. The spool comprises a cylindrical barrel, a pair of flanges and a pair of flange hubs. Formed metal curls formed of metal edges of the cylindrical barrel, the flanges and the flange hubs secure the cylindrical barrel to the flanges and flange hubs. The spool includes a plurality of detents in the tightened curls of the spool. The detents in the metal spool provide for increased torque transfer between the flanges, the flange hubs and the cylindrical barrel. The ability to transfer torque increases the applicability of the spool to wire winding and pulling functions. Flattening paste also covers a metal surface in the curl to increase the coefficient of friction therein and further increase the torque transmissibility capacity.
