Abstract
In order to realize in a device for welding of a foil tube, comprising two welding jaws, which can be moved against one another and clamp the foil tube between one another, a simple gearing, it is suggested that two rods are provided in the gearing, that each rod is connected on the one side through a joint provided on a movable part of a linear drive to the part movable transversely with respect to the direction of movement of the welding jaws, and that each rod is connected on the other side to a joint of a jaw carrier.
Claims11
A device for welding of a foil tube, comprising two welding jaws, which can be moved against one another and clamp the foil tube between one another, two jaw holders each for holding one welding jaw, jaw carriers each for carrying one of the jaw holders and thus the welding jaws, a linear drive with a movable part, which is linearly movable along an active line, a gearing connected to the movable part, whereby the gearing is connected to the jaw carriers in order to produce an opposing movement of the jaw carriers and thus of the welding jaws, and in order to be able to move the welding jaws toward one another and away from one another, and one joint on each of the jaw carriers in order to pivotally connect rods of the gearing to the jaw carriers, wherein two rods are provided, that each rod is connected on the one side through a joint provided on the movable part to the movable part which is movable transversely with respect to the direction of movement of the welding jaws, and that each rod is connected on the other side to a joint of a jaw carrier.
