Abstract
A machine for forming, filling, and sealing sacks has an unwinding device for a plastic tube, a cross-cutting device that cuts the tube perpendicularly to its principal axis of symmetry and creates tubular pieces in the process, a bottom forming means for forming a sack bottom at one end of the tubular piece, transport equipment to transport the resulting sacks through the machine, a filling station with a feeding element for filling the product in the sack, means of reducing the distance between the product discharge opening of the feed element and the bottom of the sack to be filled, and sealing means to seal the filled sack. The means of reducing the distance is a sack lifting device with which the sack can be lifted in the filling station such that an upper edge of the sack is located above the product discharge opening of the feed element.
