ABSTRACT:
A work preparation and ruling machine is provided for the production of semi-cylindrical rotary dies. The machine comprises a longitudinal cylinder mounted for rotation in frame and being provided with a series of equally spaced longitudinal rows of holes which are radially formed therein. An end wheel, of the same diameter as a finished die, is coaxially secured to one end of the cylinder and includes a first positioning means whereby the cylinder can be rotated by a distance equal to the distance between each two longitudinal rows of holes. A guide bar mounted above and parallel to the longitudinal axis of the cylinder is provided with a pair of carriages, one carrying drilling and cutting means for drilling holes in the die and for squaring it up and the second carriage includes a pen holding fixture to keep the pen aligned with the axis of the cylinder and includes means for measuring the horizontal dimensions of the layout. The sawing means is swivel mounted to cut vertical and horizontal cuts for the squaring of the wood while making dissections of any length on the cylinder.
