A method of manufacturing a battery is disclosed. The method includes the steps of (A) suction-attaching the first separator to a winding core, (B) winding the first separator on the winding core, and (C) removing the wound electrode assembly from the winding core. The winding core includes a first group of holes and a second group of holes each formed in its outer circumferential surface. In step (A), suction is applied to the first separator through at least one of the first group of holes and the second group of holes, to suction-attach the first separator to the winding core. The first group of holes and the second group of holes are configured to be controllable so as to cause suction and gas discharge independently from each other.

Apparatus for winding at least one strip of material for the production of electrical energy storage devices, comprising: a rotatable winding core, configured to grip the strip and actuatable to carry it in rotation and thus form a winding; a feed unit to feed the strip of material; and a handling device configured to move the winding core at least between a winding station, at which the winding core is configured to receive the strip in feeding, grip it and wind it about the rotation axis, and a second station; wherein the handling device is configured to move the winding core from the winding station to the second station during the winding.

A thread storage apparatus includes a core around which thread is wound for storage. The core extends along an axial direction from a top end to a bottom end. The apparatus includes a top connector on the top end of the core, and a bottom connector on the bottom end of the core. The thread storage apparatus may be selectively attached to a first adjacent thread storage apparatus along the axial direction by connecting the top connector to a connector on the first adjacent thread storage apparatus. Similarly, the thread storage apparatus may be selectively attached to a second adjacent thread storage apparatus along the axial direction by connecting the bottom connector to a connector on the second adjacent thread storage apparatus. An assembly is formed by attaching several thread storage apparatuses in series. Adaptors are used to change between different characteristics of adjacent thread storage apparatuses in the assembly.

A bobbin for winding optical fiber includes: a body around which an optical fiber is wound; a flange that extends in a radial direction from the body; and a seal that is bonded to an axially outer side surface of the flange. The flange has a void penetrating the flange. A part of the seal covers at least a part of the void. At least a part of a portion of the seal is non-adhesive. The portion covers the void.

A bungee spool for collecting and storing bungee cords in a portable manner comprising a core and two rims where at least one has multiple slots radiating and the slots have raised inner edges outward from the point where the rim joins the top of the cylinder.

A binding device binds a material strip reel on which a contact material strip is wound. The binding device includes a frame, a tape supply unit installed on the frame for supplying an adhesive tape, a first damper and a second damper mounted on the frame for clamping the adhesive tape, and a first roller and a second roller installed on the frame. The first roller and the second roller push and paste the adhesive tape between the first damper and the second damper onto a pair of opposite sides of the material strip reel.
