Winding device and method

Abstract

This paper describes a winding device for wrapping material around a flat core rotating about an axis of rotation which in turn follows a circular trajectory, controlling the rotation of the core about its axis and the orientation of its axis of rotation The law of motion of both circular trajectories (independently driven by motors via electric cams) to counteract the position and velocity changes of the material at the core inlet. The winding device is used to manufacture an electrical energy storage device.

Description

technical field [0001] The present invention relates to a winding device and method, especially for winding materials such as strips, or strips, or sheets. [0002] In particular, but not exclusively, the invention may be used in the manufacture of electrical energy storage devices. Background technique [0003] The prior art includes various winding devices for the manufacture of electrical energy storage devices. In these devices, the winding core is generally oval rather than circular, resulting in irregular and uneven movement of the material to be wound. Many compensating systems have been proposed to make the movement of the material supplied to the winding core more regular and uniform. [0004] Patent publication EP 2595233 A2 describes a device with a winding core, a compensating unit along axis Y to compensate for the vertical movement of the incoming strip, and a compensating unit along axis X to compensate for the The belt speed is varied to maintain the belt ...
