Abstract: The invention relates to a tubular bag machine and a method for the continuous production of block-bottom bags (10) comprising two side areas folded in at the bottom and a transversally sealed bottom seam, the bottom seam comprising at least one first portion with a twin film web and at least one second portion with a quadruple film web, and the bottom seam running in the base surface des block-bottom bag (10).

Abstract: The invention relates to a dispensing device (40) for being disposed in the forming tube (42) of a tubular bag machine (01) for the portioned dispensation of a flowable, in particular powdery, product (46), having at least one screw conveyor (43) discharging the product (46), said screw conveyor (43) protruding into a screw tube (41) with its longitudinal axis and being able to be rotationally driven by a drive, and having a flow barrier (45) fastened at the lower end of the screw tube (41), the amount of the product (46), which trickles down when the screw conveyor (43) is stopped, being able to be reduced by the flow barrier (45), at least one first receiving contour being provided at the flow barrier (45), and at least one second receiving contour being provided at the lower end of the screw tube (41), and a locking bolt being able to be inserted into and/or pushed through the first receiving contour and second receiving contour when disposing the flow barrier (45) at the lower end of the screw tube (41) i

Abstract: A dispensing device for a flowable, in particular powdery product, includes at least one screw conveyor discharging the product, a drive for rotating the screw conveyor about its longitudinal axis, and a forming tube for guiding a tubular film. The screw conveyor protrudes with its longitudinal axis into the forming tube, wherein at least one screw guide, in which the screw conveyor is guided transversally to its longitudinal axis, is formed by the inner wall of at least one cylindrical recess in the forming tube.
