A system for manufacturing sacks or bags includes at least two sack or bag producing machines which control components are assigned to, and which are connected with each other by at least one transport device and/or one storage device. The system includes a control unit configured such that manufacturing speeds of the two sack or bag producing machines can be transmitted to and/or processed by the control unit. The control unit is configured such that it proposes and/or sets the manufacturing speed of the two sack or bag producing machines based on system operating parameters.

System and method for producing bags or pouches

A crane gear for the transport of web rolls with a winding core, provided with a passage hole, exhibits a support frame, which is attached to a cable and which is provided with receiving units. The support frame comprises an upper yoke carrier with legs, which point in the downward direction and whose ends are provided with hooks and from which a support rod, which is slid through the passage hole, can be suspended.

Crane gear for the transport of web rolls

An apparatus for providing transverse weld seams and transverse detaching cuts or for providing detaching weld seams on a tubular or semi-tubular web of thermoplastic synthetic resin, and for stacking the detached sections includes a transverse welding and transverse detaching station for detaching sections having bottom weld seams and any leading head weld seams from the web and a stacking station for retaining or fixing the supplied sections. The web is moved intermittently. To cool the trailing weld seams of the sections without causing the sections to stick together adjacent to the bottom weld seams during stacking, a drum is provided which rotates about a transverse axis between the transverse welding and transverse detaching station and the stacking station. The wall of the drum includes at least two wall parts. The drum is adapted to be driven in step with the welding process by rotating the drum through an angular increment related to the number of wall parts of the drum in each revolution. In synchronization with stacking the cut sections at the stacking station, a path is formed for allowing the web to be pushed through gaps between the wall parts of the drum between the transverse welding and the transverse detaching station and the stacking station.

Apparatus for detaching pieces of tube provided with transverse weld

An apparatus for stacking double bags, which have been severed by hot-wire welding from a tubular web of plastic and have opening-defining edges adjacent to their center line, includes a wicketer having a horizontal shaft and pairs of juxtaposed spokelike radial feeding arms which are axially spaced apart and secured to the shaft and are provided with means for retaining the double bags. Stacking pallets provided with upstanding stacking pins are slidably movable between the feeding arms, by which the double bags are deposited on the pallets, e.g., on needles provided on the pallets. To permit a trouble-free stacking of the objects without an intermediate stacking and without an interruption of the manufacturing process, a pallet-handling member for guiding and retaining stacking pallets is provided, which extends approximately radially with respect to the shaft and is pivotally movable about the shaft and in a first position delivers a stacking pallet to a pallet holder, which is movably mounted on the shaft, and in a second position removes the pallet from the pallet holder and then moves the pallet to a stack-removing device.
