USE

The machine is used for automatic winding the foil in the course of its continuous production. The foil is wound to cores by a constant pulling force for the whole winding period.

FUNCTION

The winding cycle proceeds automatically depending on the required winding length. The foil is wound on a directly driven core. The constant pulling force in the foil is secured by a manner of the drive electric motor control. The winding machine is equipped with a preliminary pull forming the constant pulling force in the foil between the winder and the preceding machine and adapting the winding speed to the production line speed. The automatic cycle of the machine can be controlled also manually by means of buttons on the control panel, especially in the service works and in feeding the foil. The required pulling force of the preliminary pull and winding and required foil length in winding are entered using a display unit and keyboard. The foil is fed through the preliminary pulling pair of rollers on the core put on the first winding spindle and the spindle drive unit is turned on. The wound foil length is measured by means of an incremental sensor. Upon switching over to the automatic operation, the foil is wound to the required length entered in the counter where it is displayed at the same time with a momentary value. Before reaching the required length, a spindle carrier begins to rotate. The spindle with an empty core is rotating and moved to the working position. In the working position, the foil is pressed down to the core, it is divided, and begins to wind. The spindle with a full core in the handling position is stopped, the operating personnel removes lap, and mount a new empty core.

ADVANTAGES

In the course of winding, the equipment works fully automatically. The operating personnel only replace full cores with empty ones on the spindle in the handling position. The cores are fastened to the spindle by means of pneumatic spacing elements. The machine can be optionally equipped with a device for measuring the foil width. The spindles are equipped with hand-operated valves to fastening the cores. There is no manipulation with compressed air pistol by the operating personnel.
