Abstract:
A device for packaging comprising first and second spaced apart sealing jaws configured to weld a foil web extending therebetween and moving in a transport direction in a plane of movement, the first sealing jaw being carried by a support that is coupled to a drive mechanism, the drive mechanism being configured to move the first sealing jaw toward the foil web and contacting the foil web at a first position, with the foil web in a first path of movement from the first position to a second position, away from said foil web beginning at the second position, and back to the first position along a second path of movement that is different than the first path of movement, a rail extending along the plane of movement of the foil web and being parallel to the first path of movement of the first sealing jaw, the second sealing jaw being carried by a carriage that is slidably attached to the rail, the carriage being attached to the support by at least one carrier extending through the plane of movement of the foil web, so that movement of the first sealing jaw along the first and second paths of movement will cause the second sealing jaw to reciprocate along the rail in a third path of movement between third and forth positions, wherein the third path of movement is parallel to the first path of movement of the first sealing jaw.
