Abstract: Woodworking machines which can hold works in tilted positions thereby to render possible the suitable working of cave portion in said works. The woodworking machine according to the invention has a swiveling table 2 carrying a plurality of rotating jigs 4 in parallel relation to each other and a tailstock 3 carrying holders 5 corresponding to said jigs 4 for holding respective works between said holders 5 and said jigs 4, said swiveling table 2 and said tailstock 3 being located on the upper surface of a base plate 8, wherein said holders 5 are located on said tailstock 3 which can be vertically shifted according to the invention, thereby to hold said works 1 in their tilted positions.

Abstract: A wookworking machine that can easily and exactly form digitizing data for a plurality of workpieces even during the working operation on the workpieces, thereby considerably increasing the working efficiency. The woodworking machine according to the invention for working of workplaces into specified three dimensional form is characterized in that the woodworking machine is combined with a copying digitizing device and a computer connected to an NC copying digitizing device. The computer loads the NC copying digitizing device with working conditions such as work-starting points and limits, which are calculated by a CAD of the computer. The computer controls and stores the digitizing data formed by the NC copying digitizing device as a control file integrated by a main program. On the basis of the working conditions, the data is stored through the copying operation of the copying head of the woodworking machine.

Abstract: An apparatus for securing an article in a fixed position using a plurality of holders is provided. Each of the holders includes a hollow piston that is slidably mounted in the holder and is movable to ascended and descended positions. Each holder includes a suction cup at one end and an opening at the other end. A vacuum at the suction cups in sealing engagement with the article permits the holder to maintain the article in a fixed position. The piston of each holder that is not required to secure the article may be moved to the descended position. The piston may then be clamped in the descended position by engaging a hook mounted on the holder to a pin mounted on the piston.
