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 floating water mat reel that has a plurality of plates mounted to an axle. A floating water mat is selectively connected to the plates. A crank, connected to the axle is used to rotate the plates so that the mat wraps around the plate.

There are provided a hub for a flywheel and an energy storage flywheel. The hub for a flywheel is provided between a rotor and a rotational shaft of a flywheel to allow the rotor to have the same rotation speed as that of the rotational shaft. The hub includes a hollow main dome in which a through hole into which the rotational shaft is inserted is formed in one end and an opening is formed in the other end in a longitudinal direction of the rotational shaft, and that is formed by winding a composite material therearound; and a sub dome that is bonded to the rotor and is formed by winding the composite material around an outer surface of the main dome. Any one of the main dome and the sub dome expands in a radial direction of the rotational shaft along with the rotation of the rotational shaft and the rotor to allow the sub dome and the rotor to be maintained at a bonded state therebetween.

In rolls of winding equipment in a hot-rolling factory, each roll includes a lower cladding layer formed on the surface of the roll barrel and a self-fluxing alloy layer formed on the lower cladding layer by thermal spraying and containing carbide particles dispersed therein. The lower cladding layer includes an Fe-based cladding layer which has a Shore hardness of 60 or greater and which contains, in terms of mass %, 0.1-0.4 C, up to 2.0 Si, up to 3.0 Mn, 1.0-15.0 Cr, and 2.5-5.0 Ni. The lower cladding layer further contains one or more of Mo, V, and Co, the contents of Mo, V, and Co being 0.1-5.0 mass %, 0.1-3.0 mass %, and 0.5-5.0 mass %, respectively.

A wrinkle or misaligned winding caused in a separator roll is inhibited. In a slitting apparatus (6), a conveying direction of a first separator (12a) is changed to a first take-up roller (70U) side by a direction changing roller (68), the first separator is conveyed via a take-up assisting roller (69) which is provided between the direction changing roller and a first touch roller (81U) so as to shorten a roller-to-roller distance to the first touch roller, and the first separator which is being wound is pressed onto a take-up surface by the first touch roller.

The invention relates to a winding shaft (1) for receiving at least one winding core, said winding shaft having a shaft body (2) made of fiber-reinforced plastic, preferably CFRP, having two bearing points (4, 5) at each end of the winding shaft, having radially displaceable clamping elements (20) distributed over the circumference and over the axial length for clamping, holding and releasing the winding cores. The winding shaft is designed to hold winding cores having an inside diameter of a maximum of 80 mm.

The present invention provides an improved belted reel which is particularly well suited for the winding of soft, bulky tissue webs and overcomes the limitations of the prior art. The belted reel is capable of providing coordinated web tension and nip control by providing the winding parent roll with two nip pointsthe first nip formed between the winding roll and the second between the winding roll and a second support drum. Preferably the drum encircled by the endless belt lies above the second support drum and the first and second nip points lie in the same vertical plane.

Rewinder for the production of logs. A feeding element adapted to supply a paper web. A guide element adapted to guide sequentially several cores along a predetermined path between a station for feeding the cores and a winding station in which a predetermined amount of the web is wound on each core. A winding element adapted to wind the paper web on the cores in the winding station. The guide element includes a guide with a curved end section that ends in the winding station and in cooperation with the winding element, delimits a channel crossed by each core before reaching the winding station.

Provided is a method for producing a separator which method less causes a tear in the separator. The method is a method for producing a separator by slitting, in a direction in which a separator original sheet (12b) being porous is conveyed, the separator original sheet (12b) into a plurality of separators (12a), including the steps of: (a) conveying the separator original sheet (12b) in a state where the separator original sheet (12b) is in contact with a roller (77); and (b) slitting the separator original sheet (12b) at a portion where the separator original sheet (12b) is in contact with the roller (77).
