Abstract

The electronic control of all movement sequences of a device for the continuous production of bag-shaped containers or the like from thermoplastic web material is based on a microprocessor computer (6) which is supplied from the mains and is adjustable manually with respect to the film feed rate and the respective cut length. The independent drive units (4, 8, 13) of the device are controlled fully automatically, and in mutual dependence, by said microprocessor computer (6) in such a manner that the tubular film web (1), or the like, is conveyed from the film supply roll (2), through the pre-feed roll pair (3/4), via a special film-accumulation device (9) and the feed-in roll pair (7/8) to the welding-roll pair (11/13) which rotates between two positions (x, y), in each case with a constantly decelerating welding rate (from x to y) and with variable compensation rate (from y to x), with relaxation during the actual welding operation, to be subsequently severed at a specific distance from the transverse weld seam by the cutting roll (12), which rotates synchronously with the welding-roll pair (11/13), and by the stationary lower knife (16) of said cutting roll (12), in the process, synchronously, with the aid of a pin device (20/21) to be collected on the stacking plate to form a stack and therefore to be removed by means of a conveyor belt (22) safeguarded by means of a clamping lock (23). <IMAGE>
