Abstract
Abstract Method of producing the insulation of a conductor bundle having a plurality of metallic conductors spaced one from another which includes immersing the conductor bundle into a mass of insulating material heated to liquid state, and withdrawing the conductor bundle coated with liquid insulating material out of the mass of liquid insulating material at a speed that is slower than the speed at which the liquid insulating mass drips from the conductor bundle; and device for performing the foregoing method.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
100 words
Method of producing the insulation of a conductor bundle having a plurality of flat metallic conductors spaced one from another which comprises immersing the conductor bundle of mutually spaced-apart uninsulated flat metallic conductors through an unobstructed path into a mass of insulating material heated to liquid state, and withdrawing the conductor bundle with each of the flat metallic conductors thereof coated at least partly with liquid insulating material through an unobstructed path out of the mass of liquid insulating material at a speed that is slower than the speed at which the liquid insulating mass drips from the conductor bundle.
Claim 2
Dependent Claim
100 words
Method of producing the insulation of a conductor bundle having a plurality of flat metallic conductors spaced one from another which comprises immersing the conductor bundle of mutually spaced-apart uninsulated flat metallic conductors through an unobstructed path into a mass of insulating material heated to liquid state, and withdrawing the conductor bundle with each of the flat metallic conductors thereof coated at least partly with liquid insulating material through an unobstructed path out of the mass of liquid insulating material at a speed that is slower than the speed at which the liquid insulating mass drips from the conductor bundle.
Claim 3
Dependent Claim
14 words
Method according to claim 1 wherein the insulating mass is a thermoplastic synthetic material.
Claim 4
Dependent Claim
15 words
Method according to claim 2 wherein the thermoplastic synthetic material is formed of polyamide resin.
Claim 5
Dependent Claim
48 words
Method according to claim 1 wherein the insulating mass is a flame-resistant, slowly hardening epoxy resin having a hardening period that is reducible by radiation consisting of thermal or ultraviolet radiation; and which further comprises irradiating the insulating material with said radiation for reducing the hardening period thereof.
Claim 6
Dependent Claim
19 words
Method according to claim 1 which includes adding a dye to the insulating mass so as to color it.
Claim 7
Dependent Claim
40 words
Method according to claim 1 which includes, prior to immersing the conductor bundle into the liquid mass of insulating material, placing foils of insulating material between the metallic conductors of the conductor bundle so as to maintain the spacing therebetween.
Claim 8
Dependent Claim
78 words
Method according to claim 1 which includes, prior to immersing the conductor bundle into the liquid mass of insulating material, placing spacer members formed of insulating material between the respective adjacent metallic conductors of the conductor bundle, the spacer members being of such dimensions that in the subsequent immersion of the bundle with the thus spaced-apart metallic conductors into the liquid mass of insulating material, liquid insulating material will flow between the metallic conductors due to capillary forces.
Claim 9
Dependent Claim
36 words
Method according to claim 1 which includes immersing the conductor bundle into the insulating mass in a downward direction through the top of the mass and removing it upwardly out of the top of the mass.
Claim 10
Dependent Claim
21 words
Method according to claim 1 which includes immersing the entire conductor bundle except for the contacts thereof, into the insulating mass.
