Abstract
In a tubular bagging machine with two cross-sealing jaws,, which are movable toward one another and thereby cross-weld a foil tube, product that moves between the cross-sealing jaws,, interferes with the cross seam, and results in a leaky cross-seam of a tubular bag. In order to reliably recognize entrapped product,, it is suggested to measure the performance resistance of the servomotor on the cross-sealing jaws,, which are moved by a servomotor drive,, in order to determine product entrapment. The machine controller,can additionally receive from the drive,a value for the jaw position, which position value corresponds to a desired momentary jaw pressure. A product entrapment is determined from a high or measured performance resistance value from the desired value. A reliable product entrapment recognition is achieved through the use of the light-metal cross-sealing jaw.
