ABSTRACT:
An apparatus for producing tubular-pouch packages is proposed, which has a pair of endless conveyor belts subjected to underpressure in order to intermittently advance the tube. In order to attain a simple structure and low wear on the part of the tube-advancing device, the conveyor belts advancing the tube are driven continuously, and the underpressure exerted through these belts and effecting frictional engagement between the conveyor belts and the tube is intermittently controlled. A brake for the packaging material, which also works by means of underpressure, is associated with the arriving web of packaging material and is alternatively exposed to underpressure or to atmospheric pressure with the suction devices of the conveyor belts.
