A method for providing rolls of material for use in sheet form, particularly aluminum for food uses, comprising a step of rewinding the material for use in sheet form in order to form a roll; the rewinding step is provided by winding the material for use in sheet form directly on a rewinding shaft, with the material for use in sheet form in contact with a cylindrical outer lateral surface of the rewinding shaft, which is actuated with a rotary motion about its longitudinal axis, so as to obtain a coreless roll.

Provided are a winding mandrel, a winding machine, and a battery cell winding method. The winding mandrel includes a first connecting member and a second connecting member configured to be combined with the first connecting member. The second connecting member and the first connecting member are arranged coaxially, and length of the combined first connecting member and second connecting member is greater than length of the first connecting member or the second connecting member. Changing a structure of a winding mandrel improves stiffness of the winding mandrel and improves the efficiency and quality of a winding operation.

A paper roll and method of manufacturing. The paper roll includes a plurality of sheets spirally wound forming a roll. The roll includes a first end and a second end, wherein the first end forms an inner section. The inner section defines an axial passageway that extends from a first side of the roll to a second side of the roll. An adhesive that can stiffen the inner section joins the plurality of sheets of the first end. The method for manufacturing the paper roll includes winding the plurality of sheets about a low-friction tube to form a roll, applying an adhesive to the plurality of sheets at a first end of the roll forming an inner section having an axial passageway, curing the adhesive configured to stiffen the inner section, and removing the low-friction tube from the roll.

An adjustable system for forming a cushioning pad of a customized size, using a flexible material, includes a handle grip, a first extended portion attached to and extending away from the handle grip, a second extended portion slidably attached to the first extended portion and extending in parallel to the first extended portion, and a locking mechanism for locking the second extended portion in a fixed position relative to the first extended portion such that a separation between a first edge of the first extended portion and a second edge of the second extended portion is adjustable to the customize size. The first and second extended portions are configured for accommodating the flexible material to be wrapped a plurality of times around the first and second extended portions to form the cushioning pad having the customized size.

An apparatus may include a housing, a power-supply, a user-interface, a wrap-roller, a dispenser. In one embodiment, the apparatus is configured to roll an unwound hand-wrap after a workout. In another embodiment, a vending machine includes the housing, the power-supply, the user-interface, the wrap-roller, and the dispenser. In this embodiment, the housing includes a plurality of items that may aid in a users' workout and may selectively dispensed from the vending machine. The vending and use of the apparatus may be monetized for profit at sports-related establishments.

Device for manually forming spiral-shaped packaging material (3), including a reception (20) for at least partially circumferentially encompassing a wound reel (1) of a web of fiber material defining an axial direction (A) and forming an interior side (2) from which the web of fiber material is drawn for shaping the packaging material (3), and an axial support (30) connected to the reception (20), by which axial support an axial front side (6) of the reel of the web of fiber material facing in drawing direction is held, and having a dispensing opening (11) formed therein for dispensing the packaging material (3) in the axial direction (A), and comprising an interior wall section (31) facing the front side (6) and tapering towards the dispensing opening (11).
