Apparatus for insulating electrically conductive elements

An apparatus for simultaneously insulating a plurality of electrically conductive elements with thermal bonding insulative material comprising:

• a heater adapted to receive the combination of two layers of thermal bonding insulative material and a plurality of electrically conductive elements positioned therebetween, said heater being adapted to heat the thermal bonding insulative material to a pliable temperature below bonding temperature, to give the insulative material plasticity and to relieve internal stresses therein;
• a first pair of rollers adapted to receive the heated combination of the two layers of thermal bonding insulative material and the plurality of electrically conductive elements positioned therebetween, at least one roller of said first pair of rollers having an outer surface formed with alternating recesses and ridges which engage and form the layers of insulative material about the plurality of electrically conductive elements;
• heat removal and control means for cooling at least one of said first pair of rollers to conduct and remove heat from and to solidify and stabilize the layers of thermal bonding insulative material with the plurality of conductive elements positioned therebetween;
• a second pair of rollers in tandem with said first pair of rollers, said second pair of rollers being adapted to receive the layers of thermal bonding insulative material formed about the plurality of electrically conductive elements, at least one roller of said second pair of rollers having an outer surface formed with alternating recesses and ridges which engage the layers of insulative material formed around the plurality of electrically conductive elements;
• heat source and control means for heating at least one of said second pair of rollers to a temperature which bonds the formed layers of insulative materials together and around the plurality of electrically conductive elements;
• and
• frame means for mounting said adjustable heater;
• said heat removal and control means, said heat source and control means, and the first and second pairs of rollers and for supporting the thermal bonding insulative material and the plurality of conductive elements therebetween.
