Abstract:
In a mechanism for producing filled, sealed tubular bag packages from a filled tube wherein the filled tube is constricted to form the ends of two sequential tubular bag packages, and the constricted area of the tube is sealed by two surrounding, separated bent wire closures, wherein two groups of constricting plates are pressed from both sides against the area of the tube to be constricted, the mechanism comprising means for cutting and bending the wire into U-shaped bent wire closures, and a transport mechanism for the U-shaped bent wire closures used to seal the constricted area, wherein the cutting and bending means each respectively include a bending stamp and a cutting block disposed outside the constricting plates of one group, and fixed counterpieces, and are driven with the constricting plates, and wherein the transport mechanism is arranged between the constricting plates of one group and is formed by at least one rod running in a groove, the improvement wherein the constricting plates together with the cutting and bending means are driven by a common drive shaft via cam disks rotating around the common drive shaft, and wherein two bi-directionally operating cam disks are provided for each group of constricting plates, and one bi-directionally operating cam disk is additionally provided for the transport mechanism.
