  • Patent number: 8267346
    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.

  • Patent number: 7213784
    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.

  • Patent number: 6575398
    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.

  • Patent number: 6267324
    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.
