Abstract: A structure for moving tools in numeric control machines for the working of rigid and semirigid planar materials, comprising a supporting framework adapted to be arranged in a position that lies above a working surface of a numeric control machine, the supporting framework supporting at least one arm for supporting a tool head, the arm being movable along a bridge, the tool head supporting at least one tool, there being also elements for compensating vibrations and/or oscillations that are a consequence of the accelerations caused by the movement of the at least one tool head, the compensation elements being movable along the bridge, on a plane that is parallel to the movement plane of the at least one tool head.

Abstract: A cutting machine, particularly for leather and similar materials, comprising a pair of shoulders which are connected by a system of guides arranged so as to lie above a conveyor belt, at least one cutting head being movable along the guide system, the movement of the cutting head in the same advancement direction as the conveyor belt and at right angles to the guide system being distributed on two or more elements, at least one of which is cantilevered.

Abstract: A machine for cutting hides and the like and sheet-like material in general, with simplified-access worktable, comprising a footing for supporting a worktable, and cutting elements adapted to be moved on said worktable along the contours of the shapes to be cut, by way of numeric control, wherein the imaginary extensions of three sides of said worktable do not encounter obstacles due to said cutting elements and supports thereof, the fourth side of the worktable being surmounted by a cantilever arm that supports said cutting elements.

Abstract: A control unit for an electric drive motor of industrial processing machinery includes a control arrangement which drives a pair of magnets generating a magnetic flux and a Hall effect sensor disposed between the magnets so as to be swept by the magnetic flux rotatively with respect to each other; the Hall effect sensor outputs an electric signal which varies consistently with the position setting of the control arrangement and drives the electric motor accordingly; the movement of the control arrangement is resisted by springs having different degrees of stiffness from one another; proper interaction can thus be established between the operator and the machine.

Abstract: An operation apparatus for a sewing machine has an electric motor for driving the sewing machine and electronic components for operating and controlling the electric motor and sewing machine; the electric motor and electronic components are accommodated within a common, heat-conductive box-type body effective to dissipate the heat generated inside the body by the electric motor and the electronic components to the outside.
