ABSTRACT:
A method and apparatus for insulating a plurality of electrically conductive elements and to produce electrical cable where the method includes heating the unformed insulative material and conductive elements, applying pressure and simultaneously removing heat with a pair of rollers at a relatively low temperature and applying pressure and heat to preselected regions only of the insulative material. The method and apparatus further allow preselected portions of the cable to be unbonded so as to facilitate access to the conductive elements by simply interrupting the application of pressure to the preselected portions. The heat, press and cool and press and bond method may also be accomplished in a step and repeat process using presses to insulative flexible circuits. The above method and apparatus provide more reliable bonding at an accelerated rate of production.
