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: Winder with a contacting roller (10), which can be placed against the periphery of a reel (14), characterized in that the contacting roller (10) is divided at least in two roller segments (46; 34), of which at least one (34) has an engaging mechanism (38, 40), with which it can be engaged and disengaged independently of a different roller segment (46).
