Abstract: At a reel, an outer peripheral surface of a cylindrical tube portion of a reel hub is a tape winding surface around which a magnetic tape is wound. In a free state, the tape winding surface forms a substantial taper shape in which an outer diameter is greater at an upper end portion side where a radial direction rigidity is relatively low, than at a lower end portion side where the rigidity is high. In a state in which a magnetic tape is wound, the tape winding surface can form a shape that is substantially symmetrical with respect to a transverse direction of the magnetic tape. As a result, the reel and a recording tape cartridge are obtained in which the outer peripheral surface of the hub forms a proper shape in a state in which a recording tape is wound.

Abstract: There are provided a tape reel, a recording tape cartridge, a take-up reel, and a drive device at which, when a recording tape is wound on a hub, fluctuations in an axial direction of the hub can be suppressed and occurrence of tape edge damage can be prevented. At a tape reel having a hub on which a recording tape T is wound and flanges which are provided at both end portions of the hub, a large diameter portion, whose diameter is larger than diameters of both end portion sides of the hub, is formed at the hub. The large diameter portion is offset, from a widthwise direction central portion of the hub, toward the one flange side or the other flange side.

Abstract: A roller mounted onto a fabric winding machine to roll up fabric aims to solve the shortcomings of the conventional rollers that tend to cause fabric skewing during fabric rolling and are difficult to remove due to a lengthy structure. The roller of the invention has an outer diameter gradually enlarged towards two ends, and includes a first half roller and a second half roller that have respectively a first positioning portion and a second positioning portion at one end corresponding and fastenable to each other. The greater diameters at two ends allow the fabric to be rolled up on the roller without skewing. The two pieces design of the roller makes each piece shorter and removing from a bundle of rolled up fabric easier. The roller thus formed can facilitate fabric rolling and removal thereof.

Abstract: Arrangements and methods for welding wire payoff sources. A tapered core and base plate, optionally along with a wire guide insert, are configured with a payout drum package and a cover containing a welding wire stack such that the welding wire may be payed off smoothly from the wire stack during an arc welding operation, without the welding wire flipping or tangling.

Abstract: The invention is particularly directed to the problem of creep deformation in a coiled aluminum strip, which occurs during coiling and for a period thereafter. The problem arises because the profile of the strip across its width is not flat, and is in fact usually thicker in the middle than at the edges (positive crown). To compensate for this, the invention provides that the spool onto which the coil is wound is adapted to provide more support to the strip in the center than at the edges, by making the central portion of the spool of a greater diameter than the end portions of the spool. A strip having a positive crown which is wound onto such a spool was found to exhibit significantly reduced creep strain, leading to reduced creep deformation.

Abstract: A cord-wrapping device has a cord attached to a drum and includes a steeply inclined inlet portion and a second less inclined portion adjacent to said steeply inclined inlet. A cord feed guide directs the cord to begin wrapping onto the steeply inclined portion of the drum, and the slope of the steeply inclined inlet portion is sufficient that the cord slides downwardly along the slope of the steeply inclined portion toward the second inclined portion as the drum rotates to wind the cord onto the drum, without requiring an external pushing force to cause the cord to slide.

Abstract: A linear material reel design promotes the uniform spooling of a linear material around a reel drum, while also reducing stress acting on the end of the linear material that is connected to the drum. A connector ramp has a connector face generally perpendicular to the outer surface of the drum and is configured to orient the connecting section of a linear material substantially parallel to the outer surface of the drum. A guide groove promotes uniformity of spooling. A retraction limiting band maintains a length of the linear material wrapped around the drum. The retraction limiting band, guide groove, and connector ramp can be employed together or independently. Methods of spooling linear material with the use of such apparatus are also provided.
