A disclosed method is a method of manufacturing a battery including a wound electrode assembly in which a first separator, a negative electrode plate, a second separator, and a positive electrode plate are wound together. The method includes steps of winding the first separator, the negative electrode plate, the second separator, and the positive electrode plate onto a winding core, to prepare a wound electrode assembly, and removing the wound electrode assembly from the winding core. The winding core includes a first component and a second component. In the step of removing the wound electrode assembly from the winding core, at least one of the first component and the second component moves in a direction in which a distance between the first component and the second component decrease so that a diameter of the winding core decreases. Thereafter, the wound electrode assembly is removed from the winding core.

A method of manufacturing method a battery includes the following steps. Step (A): causing, with the first separator and the second separator being stacked on each other, the first separator and the second separator to be suction-attached to a winding core and to be pressed against the winding core with a jig including a plurality of protrusions formed on a surface of the jig. Step (B): winding the first separator and the second separator onto the winding core.

A variable-diameter adsorption winding needle mechanism and a winding machine are provided. The variable-diameter adsorption winding needle mechanism includes a winding needle assembly, a first adsorption winding needle, a second adsorption winding needle and a pin assembly. A plurality of adsorption holes are provided on the outer peripheral surfaces of the first adsorption winding needle and the second adsorption winding needle. At the same time, the winding needle assembly is also used to drive, under the driving of the pin assembly, the first adsorption winding needle and the second adsorption winding needle to move close to or away from each other.

The present specification relates generally to devices for configuring pliable articles and more specifically to a device for rolling fabric articles for storage and related method. The device for rolling fabric articles for storage and the related method may facilitate the storage of a greater number of fabric articles within a given space, without rendering the stored articles inaccessible. The fabric rolling device comprises a housing; a pair of substantially parallel rods each having a first end, the pair of substantially parallel rods connected to each other at the first ends and extending horizontally through the housing; a rotational mechanism in communication with the connected first ends of the pair of substantially parallel rods; and at least one supporting mechanism, disposed within the housing proximate one of a free end of each of the pair of substantially parallel rods and the connected first ends of the pair of substantially parallel rods.

A method for producing coreless roll paper includes a winding step in which paper 11 is wound on a shaft 20 in a roll shape, and an extracting step in which the shaft 20 is extracted from roll paper 12 to form a center hole 13. The shaft 20 includes a body part 22 having grooves 23, and a sleeve 30 is put on and fixed to the body part 22. In the winding step, the paper 11 is wound on the sleeve 30.

Equipment for removing paper from parent reels used for the production of paper logs of paper material, including a support system adapted to support an exhausted parent reel, where the exhausted parent reel includes a tubular core on which residual paper to be removed is wound, and including removal capabilities for removing the residual paper from the core when the exhausted parent reel is placed on the support system. The removal capabilities include a suction cylinder having a horizontal axis onto which the paper is transferred by effect of the contact between the suction cylinder and the exhausted parent reel and by effect of the rotation of the suction cylinder around the horizontal axis.

The present invention relates to a holding system for holding sheet material for plotters characterized in that it comprises at least one substantially tubular side holding element (1), at least part of the external surface (2) thereof being tapered. Furthermore, said side holding element (1) comprises a longitudinal opening (7) and has internal chamfers at one of its ends (4). As a result of the thickness and the tapering of the external surface thereof, the side holding element hold the sheet material and, simultaneously, ensures that there is a gap between the winder tube and the sheet material wound on said tube, which facilitates its removal from the tube.

A compressed coreless rolled product is described, including an inner surface defining a central cavity having an inner diameter and an outer surface having an outer diameter larger than the inner diameter. The outer diameter is at least five inches and a ratio of the inner diameter to the outer diameter is at least 0.35. Also described is a compressed coreless rolled product with similar inner and outer surfaces, wherein: a difference between the outer diameter and the inner diameter defining a thickness of at least 2.9 inches; and a ratio of the inner diameter to the outer diameter is at least 0.35. An associated method of producing the product is also described, including steps of: winding an absorbent sheet around a forming core member; removing the forming core member to form a coreless rolled product with a diameter ratio of at least 0.35; and compressing the product.

Provided is a wound body formed by winding a long sheet. The wound body is supportable by a support shaft. The support shaft includes a cylindrical outer peripheral part that includes a first projection located at a proximal end and a second projection located at a distal end, and includes an inner peripheral part that includes a first recess part located at the one end and recessing outward in the radial direction and a second recess part located to extend from the one end to the other end and recessing outward in the radial direction. A recessing amount of the second recess part is smaller than that of the first recess part. The support shaft and the core body are integrally rotatable around the central axis by engagement of the first projection with the first recess part in a state where the core body is mounted on the outer periphery of the support shaft. The circumferential position of the first projection around the central axis is aligned with the circumferential position of the first recess part around the central axis by engagement of the second projection with the second recess part when the core body is mounted on the outer periphery of the support shaft.

A substrate case includes a shaft portion around which a sheet-shaped substrate having a circuit area in which a circuit manufacturing process is performed is wound; and a cover portion that accommodates the substrate in the state of being wound around the shaft portion, the shaft portion having a holding portion that holds an area different from the circuit area at a winding start portion of the substrate.
