Abstract
A ram-driven cut-off die set of the double-cut type in which sections of tubing are successively severed from a continous length of tubing by a notching cut followed by a severing cut wherein improved means are provided for mounting and guiding the notching blade in its notching movement. The improved mounting means comprises an upper shaft positioned over the tube path and extending from one side to the other side of the path, a lower guide shaft positioned totally on the one side of the tube path, and a cross slide having a relatively long upper portion slidably journalled on the upper shaft and a relatively short lower portion journalled on the lower guide shaft to maximize the magnitude of the journalling support provided to the notching blade as it makes its reciprocal movement across the tube path to accomplish the notching cut.
