Abstract
An apparatus for use in a tube manufacturing plant wherein a coiled strip is made into a continuous tube. The tube is fed to the apparatus at a given speed and severed into a specified length with minimized errors in accordance with the contemplated use by a cutting assembly traveling in synchronism with the feed of the tube. When the speed of the cutting assembly matches the speed of the tube, a ram is lowered from above by a crank assembly to cause a notching blade and a cutoff blade to cut the tube without dimples. The ram is elongated and supported by a plurality of crankshafts which are adapted for synchronous rotation optimally by a synchronizing link. For dimpleless cutting, the notching blade is revolved and thereby moved at an increased speed to form a deep and wide notch in the tube.
