Abstract

428,937. Coiling. TONDEUR, R., 25, Denbigh Terrace, Notting Hill, and BOWDEN (ENGINEERS), Ltd., Victoria Road, Willesden Junction, both in London. Nov. 20, 1933, Nos. 32375/33 and 2021 /34. [Class 83 (iv)] In making flexible tubing of closely interwound open coils for Bowden mechanism as described in Specification 412,367, [Group XXIV], wires 47, 46 are wound through tangential holes in a die 7 by a mechanically operated chuck 10. A mandrel 8 passes through the die 7. The wound tube is gripped by the chuck 10 rotated from a shaft 11 and the wires are pulled simultaneously through the die to force one wire between the convolutions of the other. Resistance to the opening out of the leading coil is offered by the die 7 which moves backwards along a slide 18 against pressure of a spring 20. When a few coils have been formed the chuck is opened by a cam 14 and a cam 15 moves the die forward to feed the coils through the chuck. The chuck is then closed and the operation repeated. To start the machine, the end of one wire is bent and engaged by an apertured sleeve secured to the chuck to start the coiling and the second wire is then started. The sleeve is then removed and the coiling commenced. To place the wires under tension they are fed through spring-pressed wire guides 24, 25 which are angularly adjustable. The wires may be formed of triangular, trapezoidal or round section and are wound to allow of the tube being flexed without varying the axial length of the tube. The chuck may be provided with roller jaws to pull the formed tube continuously from the machine. Four or more even number of independent coils may be interwound.
