Title: Improvements in or relating to apparatus for coating wire with extruded insulating material
IPC: B29C48/15
Filed: 1954-08-24
Abstract: 752,616. Automatic control systems. WESTERN ELECTRIC CO., Inc. Aug. 24, 1954 [Sept. 3, 1953; Sept. 3, 1953; Sept. 3, 1953], No. 24594/54. Class 38 (4). [Also in Group XXXVI] The invention relates to the manufacture of telephone cable containing a number of individually insulated wires which are required to have a uniform capacitance to ground. According to the invention a wire is coated with a layer of extruded insulating material as it is drawn continuously through the extruder and the capacitance of successive portions of the insulated wire is measured with respect to a surrounding water-bath through which it passes on leaving the extruder. Deviation of the capacitance from the required value, varies the speed of the capstan motor pulling the wire through the extruder, thereby varying the thickness of the insulation coating to maintain a uniform capacitance per unit length. The length of wire measured may be defined: (i) by a V-channel electrode in the water surrounded by a guard electrode, Fig. 5, and Figs. 1 and 4 (not shown); or (ii) by a bath of the required length with semi-water-tight glands at each end through which the wire is drawn, Figs. 7 ... 13 (not shown), and Fig. 14. The capacitance error signal may be derived from a differential circuit, Fig. 5, wherein an oscillator 56 feeds through one half of a transformer primary winding to a standard capacitance 50, and through the other half of the winding to an electrode 27 in the water bath, the wire being earthed. (As shown, the guard electrode 32 is also energized from the oscillator.) Lack of balance causes an error voltage, in the secondary winding 48, to control the capstan motor 18. Alternatively the capacitance error may be detected by an R.C. bridge 70, Fig. 14, connected to a phase-sense -discriminator circuit comprising a double triode 87 with the anodes connected in parallel and one grid fed from the bridge, and the other from a reference voltage derived from the oscillator, whereby the output varies above or below the reference value according to the magnitude and sense of the error. The output is rectified at 119 and the standing D.C. signal due to the reference voltage is backed off by a potentiometer 122. The D.C. error signal controls (through an invertor 128) a two-phase servomotor 128 driving a rheostat in the capstan motor control circuit.
