  • Patent number: 7140089
    Abstract: One embodiment of the present invention is a compact, low-cost, lightweight, versatile and easy-to-operate, processor-controlled carving and multi-purpose shaping device (“PCCMPS machine”). The PCCMPS machine that represents one embodiment of the present invention is configured, in part, similarly to common, commercially available portable wood planers and ubiquitous laser and ink-jet computer printers, with work pieces fed into the PCCMPS machine in a horizontal direction. The PCCMPS machine includes a motor-powered cutting head that can power detachable bits to drill, cut, shape, and rout a work piece under processor and computer control. The cutting head may be translated, under processor control, back and forth across the surface of the work piece in a direction perpendicular to the direction in which the work piece is fed into the PCCMPS machine and moved by motor-powered rollers.

  • Patent number: 6516693
    Abstract: The invention consists of a process for the control of the motorized feed drive for the movable workplace table of a machine tool, in particular the rolling carriage of a circular saw. The manual force that is applied by the operator in direction of the feed is sensed and converted to a corresponding measured value. From this a set value for the feed rate of the rolling carriage is created and from that is derived a control signal for the drive.

  • Patent number: 6390160
    Abstract: The chopping machine includes a crosscutting device for cutting the timber, a feeder for feeding the timber in its longitudinal direction to the crosscutting device and a splitting apparatus operated by a splitting cylinder for splitting a cut block of timber. The feeder includes two elongated supporting surfaces forming a substantially horizontal trough open in the upward direction, into which the timber to be treated can be placed. One of the supporting surfaces is connected to a power device for moving the supporting surface back and forth in the longitudinal direction of the trough, and the supporting surfaces are provided with directional holding elements arranged in the longitudinal direction of the trough to prevent the timber from moving in relation to the surface away from the crosscutting device.

  • Patent number: 6220315
    Abstract: A method for processing of workpieces, which are supplied to a processing station, in which the workpieces are processed on one side, are moved out of the processing station, and are turned and again supplied to the processing station for processing the second side. In particular, a workpiece or workpiece package is individually supplied to the processing station, is processed there and individually moved on following the processing of both sides. The first side of one workpiece, whose second side has not yet been processed, and the second side of another workpiece whose first side had already been processed in the previous processing operation, are processed in one processing operation in the processing station, so that during each processing operation a workpiece processed on both sides is created together with a workpiece processed only on one side.
