Abstract

A winding and cutting device for winding a wire on a connection pin of electrical components, and for the purpose of cutting off the excess remaining wire in one work cycle. A stationary sleeve is provided with a rotatable mandrel which has a central bore which is open at least in the direction of its one front face into which the pin is inserted during winding and which has, at least in the winding area, a diameter corresponding at least to the winding diameter. The sleeve and the mandrel have a slanted slot which is open at least in the direction of the one front face and which is aligned relative to the bore.

  1. 1. A winding and cutting device, comprising: means for winding a wire on a connection pin and for severing excess remaining wire prior to winding the wire, all in one work cycle; said means including a stationary sleeve having a mandrel means rotatably arranged therein for winding the wire therein; a central bore in the mandrel means having an open end at least in a direction of a front face of the cutting device into which the connection pin is inserted during winding, the bore having at least in a winding region a diameter corresponding at least to a diameter of the winding; and the sleeve and the mandrel means each having a slanted slot which are open at least in a direction of said front face and which form a channel from the bore to a side of the sleeve for the wire when the two slots are aligned.
  2. 4. A winding and cutting device, comprising: means for winding a wire on a connection pin and for severing excess remaining wire prior to winding the wire; said means including a stationary sleeve having a mandrel means rotatably arranged therein for winding the wire; a central bore in the mandrel means having an open end at a front connection pin insertion face of the cutting device, the bore having a length sufficient to accommodate the connection pin and an enlarged winding region at the front face having a diameter which is greater than adjacent portions of the bore and which is sufficient to accommodate the wound wire on the connection pin; and the sleeve and the mandrel means each having a slot which forms a channel for the wire from the central bore to a side of the stationary sleeve.
