ABSTRACT:
Thin strip cores wound by apparatus having a spool for winding a ribbon-like thin strip, a clamping device for clamping and moving the ribbon-like thin strip, a winding core driving device for causing the ribbon-like thin strip clamped by the clamping device to be wound in a prescribed length around a winding core, a cutting device for cutting the ribbon-like thin strip after the ribbon-like thin strip has been wound in the prescribed length around the winding core, a welding device for welding the trailing end of the wound thin strip cut off, a releasing device for releasing the connected wound thin strip, and a measuring device for taking the weight of wound thin strip released. This invention can produce the thin strip core quickly because all of the works involved in the production of the thin strip core are automatically carried out without requiring any manual operation. Further, it imparts a fixed weight to all of the wound thin strip of product owing to the procedure which comprises weighing each wound thin strip immediately after the wound thin strip is cut off and setting the number of plies of winding for the next wound thin strip in due consideration of the cycle of thickness of thin strip so that the next wound thin strip will assume the prescribed weight.
