Abstract: A drum assembly includes a core having a first end and a second end opposite the first end, a first hub coupled to the core adjacent the first end of the core, a second hub coupled to the core adjacent the second end of the core, a first flange releasably coupled to the first hub, the first flange including a body having an inner surface, an outer support structure, and an aperture formed therethrough, and a second flange releasably coupled to the second hub, the second flange including a body having an inner surface, an outer support structure, and an aperture formed therethrough.

Abstract: A tape reel includes a first flange, a cylindrical body, and a second flange formed separately. The first flange, the cylindrical body, and second flanges are joined with inner surfaces of the first and second flanges contacting the cylindrical body. Joining pins are erected on the inner surface of the first flange. The cylindrical body includes an outer wall, bosses with through-holes for the joining pins fixed to the inside of the outer wall, and an inner wall positioned inside and following the outer wall. The second flange has an opening formed in the center and a protrusion at an opening edge protruding toward the center and including through-holes through which the joining pins are inserted. Plural positioning pins that contact an outer surface of the inner wall in a state where the cylindrical body is contacted to position the cylindrical body are formed on the first and/or second flange.

Abstract: To secure the end part of a metallic filament taken up onto a reel, the take-up reel for metallic filament has a recessed portion (3) provided in the inside surface of a flange (2), the recessed portion (3) extending in the radial direction to the flange outer edge (2a); and a connecting portion (4) that straddles the recessed portion (3). A tabular end retaining member (5) having elasticity is fitted into the recessed portion 3. The base end portion (5b) of the end retaining member (5) is passed under the connecting portion (4) and butted up against the end surface (3a) of the recessed portion (3) on the winding drum side, and a space (A) is provided between the tip end portion (5a) of the end retaining member (5) and the flange outer edge (2a) to allow the end part of the metallic filament (W) to be caught therein. The end retaining member (5) is anchored to the connecting portion (4) through spot welding, using a welding portion (6) set in the vicinity of the base end portion.

Abstract: A wire spooling system for spooling and dispensing wire. The wire spooling system includes a first spool member, having a tubular member with a locking cap and first collar, and a second spool member, having an engagement aperture and second collar. The tubular member extends through the first spool member substantially transverse to the first spool member. The locking cap is positioned at the end of the tubular member opposite the first spool member. The first collar protrudes from the first spool member in the same plane and direction as the tubular member. The second collar protrudes from the second spool member and fits within the first collar. The spool members thereby form a spool shape. Upon fitting the second collar within the first collar, the engagement aperture receives the locking cap of the tubular member, securing the first spool member and second spool member in a locked position.

Abstract: A flange is for use in a reel for supporting a wound flexible medium. The reel includes an elongated core defining a longitudinal core axis. The flange includes a first annular wall oriented substantially perpendicular to the axis and engaging the core. A second annular wall is oriented substantially perpendicular to the axis and is offset in an axial direction from the first annular wall. At least one connecting wall interconnects the second annular wall and the first annular wall. A first annular rim is attached to the first annular wall or the second annular wall and is oriented substantially parallel to the axis.

Abstract: A rotatable composite reel apparatus for use in association with an axle for winding, storing, transporting and unwinding various windable materials therewith, including a tubular spindle member and first and second composite platform members, held together by one or more straps passing through aligned apertures in the first and second composite platform members. At least one of the first and second platform members is fabricated at least in part, from a high-density composite fiberboard and perpendicular corrugated paperboard material. Corrugated paperboard material is also employed in the construction of at least one of the first and second platform members.

Abstract: A spool for optical fiber ribbon or other flexible media has an opening communicating with an interior of the spool in which a first end of a helical guide is located. The helical guide receives the ribbon from an exterior winding space to direct the ribbon to an auxiliary winding surface located outside one of the main flanges at an end of the spool.

Abstract: A flange design for spools and reels may be provided from molded materials such as plastics. Improved strength, stiffness, fracture resistance, energy absorption, and toughness may be provided by appropriate design of corrugations extending substantially radially from a hub or core portion toward a rim portion. Spools and reels may be produced from Styrene plastics, olefinics such as polyethylene and polyprophelene, and may have tubes formed from the same or different materials. Flanges may be designed to crush near a rim or to be stiff near a rim. Likewise, portions of a flange may be designed to buckle, fracture, or otherwise fail sufficiently to absorb energy, while protecting a spool from excessive fracture or distortion. Likewise, portions of the flange may be designed to fail while others nearby do not, in order to protect against catastrophic failure (e.g. extensive separation).

Abstract: A wooden spool held together with a novel tie rod assembly and a method of assembly the spool between a pair of dies. The novel tie rod assembly includes elongate tie rods having a bent end or otherwise deformed first end and a plurality of grooveless retaining rings. The tie rods are inserted through the end flanges and the transverse barrel of the of the spool. The retaining rings are pressed axially on the smooth second ends of the tie rods which project axially from one of the flanges. The spool can be assembled between a pair of dies. The base die includes locating recesses to receive the bent ends of the tie rods and the top die includes engaging pins for pressing the retaining rings on the opposite ends of the spool.

Abstract: A coiled pipe dispensing rack for use in cooperation with a moving vehicle to effectuate the unrolling of plastic pipe, with the rack comprising a main cage, a hub and spindle assembly, and a mounting unit. The main cage comprises a first portion and a second portion which cooperate with each other to retain a coil of plastic pipe therebetween. Both the first and second portion each comprise a center plate, a plurality of strut arms, and an exterior side wall, with each of the strut arms connected to and radiating outwardly from the respective center plate, and with each of the strut arms connected to the respective exterior side wall. The hub and spindle assembly is positioned intermediate the main cage and the mounting unit. The mounting unit remains in contact with the moving vehicle as the pipe is unrolled.
