Abstract

Flat cable 10 is made by encapsulating plural coplanar conductor wires 11 between heat bondable dielectric ribbons 12 and 13. Heat is applied to the interfacing surfaces of ribbons 12 and 13 as they pass over chill blocks 14 and 15, and cooling roller 16 and 17, and into the nip of the rollers with the wires 11. In this apparatus, the heating means comprises heat platen assemblies 18 and 19, mounted to be in contact with the upper surfaces of ribbons 12 and 13 and to float thereon as the ribbons move over chill blocks and rollers.

Electrical Cable Making Apparatus

Flat cable 10 is made by encapsulating plural coplanar conductor wires 11 between heat bondable dielectric ribbons 12 and 13. Heat is applied to the interfacing surfaces of ribbons 12 and 13 as they pass over chill blocks 14 and 15, and cooling roller 16 and 17, and into the nip of the rollers with the wires 11. In this apparatus, the heating means comprises heat platen assemblies 18 and 19, mounted to be in contact with the upper surfaces of ribbons 12 and 13 and to float thereon as the ribbons move over chill blocks and rollers.

The heat platen assemblies 18 and 19, as shown in Fig. 2, consist of a rectangular metal block 20 machined to receive cartridge heaters in openings 21, a hot air gun 22 and a temperature sensor 23.

This platen assembly is secured to a stationary mounting plate 24 by shoulder screws 25 and 26. The head portions 27 and 28 of screws 25 and 26 extend above mounting plate 24 to permit vertical movement of block 20. Openings 29 and 30 in plate 24 are laterally elongate to permit limited movement of block 20, while moderately restricting horizontal motion in the direction of motion of the ribbons 12 and
13.

As the ribbons 12 and 13 move, the platen causes the interfacing surfaces to become slightly liquid. Since the platens 18 and 19 are allowed to move laterally and vertically, they float on this liquid surface. It was found that the platens do not require lateral alignment when the ribbons are in motion. Lik...
