Claim 1
Independent Claim
83 words
THE METHOD OF SHIELDING WIRE COVERED WITH INSULATION WHICH COMPRISES FEEDING THE WIRE ALONG A PREDETREMINED PATH PAST FIRST AND SECOND LOCATIONS, AT SAID FIRST LOCATION FOLDING SHIELDING RIBBON AROUND THE WIRE TO FORM A TUBE, BETWEEN SAID LOCATIONS APPLYING HEAT TO THE EDGES OF THE RIBBON TO WELD THEM TOGETHER AT A SEAM WHILE SHIELDING SAID INSULATION AGAINST THE HEAT, AND AT SAID SECOND LOCATION COMPRRESSING THE TUBE TO SMOOTH OUT THE SEAM WHILE PROTECTING SAID INSULATION AGAINST PRESSURE OF THE SEAM
