A strapping machine includes a supply unit, a guidance frame, a pressing plate, feeder runners, a closure aggregate, a storage unit, a feeder, an insertion device and a guidance structure. The closure aggregate is vertically aligned with the pressing plate and maneuverable, whilst the supply unit is located within close proximity of the strapping area and the pressing plate. The guidance structure includes one canal-like transfer line leading at least to the closure aggregate. The insertion device is accessible from outside, is aligned with the supply unit and is attached to a lower section of an automatically opened guidance canal. The strapping material is fed synchronically to the transfer line with the pressing plate adjustable for height. The insertion mechanism incorporates feeder and runners. The storage unit adjacent to the supply unit is aligned to the exterior of the strapping area.

Machine for the strapping of compressible packaged goods in particular, such as corrugated cardboard layers

A strapping apparatus includes a conveyor for moving the pack to a strapping station containing, a strap guide duct and a tautening and sealing head. The strap guide duct is mounted laterally offset from the direction of conveyance and being curved and twisted toward this conveyance direction in order to subtend a clear inside space for the pack which thereby can be moved unhampered into and out of the strapping station. A guidance element is associated with the strap guide duct to center the strap being released from the strap guide duct on the pack in the strap in the strapping station. The strap guide duct includes corner deflection elements, duct segments which guide the strap always at its outwardly facing side in merely supporting manner, strap twisting segments inserted between the corner deflection elements and guide ducts and imparting a twist to the strap about its longitudinal axis.

Apparatus longitudinally strapping a package, in particular a stack of newspapers, magazines or the like

The invention concerns a process and a device for avoiding interruptions of operation caused by the strapping, on machines for the strapping of packing elements. The process is characterized by a second strapping coil with further strapping, and in that the leader of one of the two strappings is constantly kept at a standby position in the machine from which, upon removal of the other strapping from the strapping guideway, it is automatically fed to the strapping guideway. The device is characterized in that the feed system is preceded by a switch with two strapping guideways for a leader section for each one of the two strappings, with a strapping feed for the alternative introduction of one of the two strapping leaders into the feed system. A first drive system is provided within the vicinity of the strapping guideways for selectively introducing one of the strapping materials into the feed system, while a second drive system is provided within the vicinity of the supply coils of the strapping materials for selectively engaging one of the supply coils in order to retract or withdraw a damaged or depleted strapping material from the feed system and permit a second one of the strapping materials to be introduced into the feed system.
