Abstract:
A device for the production of tubular bags filled with bulk goods from a continuous foil tube moving through the device comprising:a pair of moveable sealing tools positioned on opposite sides of the foil tube, the sealing tools configured to come together to seal the tube, each sealing tool including a closing bar having a bias toward the closing bar on the opposing sealing tool and adapted to move with the sealing tool to contact the tube, a sealing jaw positioned opposite the sealing jaw on the opposing sealing tool so that when the sealing tools come together the sealing jaws contact the tube to thereby seal the tube, a stripper located downstream from the closing bar in the direction of movement of the foil tube and being configured to move along the tube in the direction the tube having a is moving to strip the bulk goods away from the area of the tube to be sealed at the same time that the sealing jaw is moving toward the tube, a support bar connected to the closing bar and aligned in the direction of movement of the closing bar, wherein the support bar is configured to move in a direction generally perpendicular to the movement of the tube against the bias on the closing bar, and a moveable tracer pin operatively connected to the support bar and the stripper so that when the support bar moves the motion of the support bar is transferred to the stripper through the pin.
