Title: Improvements in and relating to apparatus for stripping insulated wire
IPC: H02G1/12
Filed: 1949-03-09
Abstract: 664,925. Stripping cables. SONNENFELD, H. March 9, 1949, No. 6426/49. Class 36. An apparatus for removing inflammable fibrous insulation from an enamelled wire 20 comprises two members 1, 8 at least one of which is heated and which are adapted for fast relative movement and are shaped so as to contact with the length of wire that is to be strpped when it is positioned between them. The block 1, which is heated as by a Bunsen burner 4, is held stationary. The block 8, heated by a burner 4<SP>1</SP> is mounted on a pistonrod 10 connected to a piston 12. A spring 13 normally holds the block 8 away from the block 1, but the block may be moved towards the block 1 by the introduction of compressed air into the chamber 14, an adjustable escape valve being provided in this chamber to regulate the speed of the piston. A fibre covered enamelled wire 20 is placed on the block 1, those portions of the covering adjacent ths block being coated with a varnish. The block 8 is moved on to the wire in a series of short sharp blows. The heat applied burns away the fibrous insulation of the part of the wire on block 1, sets the varnish to prevent fraying of the remaining fibres, and makes the enamel brittle so that it cracks readily under the hammer action. The block 8 may alternatively be moved by a fly press or cam mechanism or in any other convenient manner. Specifications 244,586, [Class 56], and 581,618 are referred to.
