Особенности

The packaging film is drawn across the filling pipe, shaped into a tube, and given a lengthwise seam. This process is controlled by the transport rollers. As soon as the required bag size is reached, the two sealing bars are closed to seal the bag and the film is cut.

Before the bag is sealed, it is filled with the appropriate volume of goods. Proportioning is usually performed using combination weighing scales.

The film is drawn off with the aid of a compensating controller. The film take-off is controlled with reference to either pressure marks, position or time.

Область применения

Vertical tubular bagging machines are economical and compact.
