摘要

An apparatus for slitting workpieces has a machine frame which includes a work support, a workpiece stop and a rotary saw which is slidable in the frame. The frame is supported on feet, at least two of which are positioned on a line parallel to the feed path of a workpiece into the apparatus. Another of the feet can be hydraulically withdrawn to allow the machine frame to tilt about an axis defined by engagement of the aforesaid two feet with a bedplate, and thereby to bring the work support and the lower part of the workpiece stop below the workpiece feed path, so that a workpiece may be advanced unobstructed into the apparatus. The apparatus is tilted back to its working position after the workpiece is in its desired position.
