Abstract
A tubular-bag packaging machine having at least one pair of cross-sealing jaws (25) which are supported on a holding device (15) movable vertically back and forth by means of a connecting rod (14) as well as horizontally through a four-bar mechanism comprising a crank disk (9) coupled with the connecting rod (14), and comprising side-fold-forming means (23, 24) which are supported on a guide element (18) movable transversely with respect to the direction of movement of a foil tube (41). In order to be able reliably synchronize the movement of the side-fold-forming tools (23, 24) with the sequence of movement of the remaining tubular-bag packaging machine, in particular the cross-sealing jaws (25), the invention provides that the guide element (18) is supported on the holding device (15), that the guide element (18) is coupled with an arm (39) pivotally supported on the holding device (15), which arm (39) is operatively connected to a rocker arm (33) pivotally supported on the connecting rod (14) and the lower end area of which cooperates in the area of the crank disk (9) with a cam element (11) associated with the crank disk (9).
