Abstract: Device for stacking tube sections (30) for producing bags, with a transporting facility (12), which supplies the tube sections to a stacking station (10), characterized in that the transporting facility (12) has an upper transport (14) and a lower transport (16) and that the lower transport (16) is formed in the region of the stacking station (10) by two endless conveyor belts (44), which revolve above the stacking station outside of the lateral edges of the tube sections (30) and are connected by at least two cross members (48, 50), which are disposed with uniform spacings, the spacings of which corresponding to the spacings between the leading edges of consecutively supplied tube sections (30).

Abstract: Tear-off device for sections (48) of a continuous sheet (18) with a pullout mechanism (10) for the transport of the continuous material (18) and with a tear-off mechanism (12), which has at least two pressure-applying elements (26; 56), which are disposed on opposite sides of the continuous material (18) and of which at least one can be engaged against the continuous material (18) by means of a positioning device, with the engagable pressure-applying elements (26; 56) being constructed as eccentric rollers and can be driven individually or jointly.

Abstract: Tear-off device for sections (46) of a continuous material (18) with a pullout mechanism (10) for the transport of the continuous material (18) and with a tear-off mechanism (12), which has at least two pressure-applying elements (24, 26, 70), which are disposed on two opposite sides of the continuous material (18) and of which at least one can be positioned against the continuous material (18) by means of a positioning device, with the positioning device having at least one motor (42; 49; 60) and a control device (43) for the temporal control of the motor (42; 49; 60), with which the pressure-applying elements (24; 26; 70) can be positioned at a controllable point in time.

Abstract: Device for the alignment of tube segments, especially with several stagger-cut layers of paper at the ends, exhibiting mutually parallel first conveyor belts on which the tube segments lie with their wide sides facing the direction of travel, as well as second conveyor belts carrying stops arranged at preset intervals, wherein conveyor belts are aligned at an angle relative to the direction of travel. The first conveyor belts are aligned in the direction of travel and the second conveyor belts at an angle relative to the direction of travel. The stops on the second conveyor belt are entrainment devices designed to engage the back wide side of the tube segments, their purpose being to push an end of the tube segment on the first conveyor belt up to a sensor that operates without making contact. A signal from the sensor triggered by the end retards the second conveyor belts, which is leading first conveyor belts, in such a way that further transport will be taken over exclusively by the first conveyor belts.
