    Abstract: A tensioning device (100) for a chain driven jaw system (200) in a package filling machine is disclosed. The chain driven jaw system (200) has a fixed cam (101) and a chain (102) as a follower. The tensioning device (100) comprises a chain tensioning element (103) shaped and angled so to receive the chain (102) on an outer surface (104) thereof configured to be directed away from a center (C) of the chain driven jaw system (200), wherein the chain tensioning element (103) comprises a pivot connection (105), and wherein the chain tensioning element (103) is configured to be integrated with the fixed cam (101) at the pivot connection (105) such that the chain tensioning element (103) abuts the fixed cam (101) at the pivot connection (105) and can move to tension the chain (102). A chain driven jaw system (200) and a related method is also disclosed.

    Abstract: The present invention relates to a packaging machine (500) for packaging pourable food products and producing sealed packages, comprising means for longitudinally sealing a web of continuous packaging material to form a tube, and sealing means for clamping and sealing the product-filled tube at spaced intervals. Said sealing means comprises a first two sets of mutually cooperating first heat sealing jaws (10) and first counter sealing jaws (20) respectively, and a second two sets of mutually cooperating second heat sealing jaws (10) and second counter sealing jaws (20) respectively. The sealing jaws (10,20) of at least one of said first and second two sets are carried by chain conveyors which are manageable between a first and a second state to make the packaging machine operable in a first state and in a second state, allowing manufacturing of different types of packages.

    Abstract: The present invention relates to a packaging machine for producing containers for pourable food products by sealing and cutting a continuous tubular packaging material web (15) between consecutive packages. The machine comprises at least one pair of cooperating sealing jaws (10), which are pressed together to form a sealing in the packaging material web. The jaws are operable to move along said tubular web and to clamp it synchronously with the feeding of the material web. In order to facilitate design correction, the machine comprises means (25, 27) for detecting the position of the material web and for comparing the material web position with the position of the sealing jaws (10). Also, there are means (16, 18, 24) for controlling the in-movement of the sealing jaws with respect to the longitudinally-sealed liquid-filled packaging material tube (15). In this way, more or less of the tube is drawn in by the sealing jaws, past the point of sealing.
