A pair of cylindrical wire brushes are mounted one above the other and arranged for simultaneous rotation and axial reciprocation in opposition to each other. The brushes are carried by respective, generally L-shaped arms which are supported on a common vertical pivot. The generally axial reciprocation is achieved by rotational oscillation of the supporting arms.
A method and apparatus for stripping insulation from an elongated electrical cable, or the like, by the action of spaced, rotating abrading wheels which are mounted for movement along guides in a direction transverse to the axis of the conductor, which is stationary during the stripping operation.
A method for stripping insulation from a region, a so-called window, of a flat cable, a so-called FFC, by means of a laser. The laser used to form the window, preferably a CO.sub.2 laser, operates only in the edge region of the window, and in a subsequent step the remaining insulation in the interior of the window is removed. This remaining insulation is preferably removed by means of a type of doctor blade or a brush.
A grinding machine for continuous descaling, cleaning and polishing of steel wire and the like employs a plurality of grinding wheels which are self-adjusting for wear and self-trimming so that no manual adjustment or trimming is required for the life of a wheel. The wheels are made of an open-pore resilient abrasive material and canted with respect to the workpiece to provide more effective descaling than that provided by prior art grinding machines. Guides are employed to align and straighten the workpiece as it is moved past the grinding wheels.
