rolling and shaping: starting a servo motor (5), driving the threading pipe (3) to rotate at a constant speed through a belt (501) and a driving roller shaft disc (502), enabling the cable body (8) to pass through the middle position of every two wire clamping boxes (303), wherein rubber guide wheels (306) on the wire clamping boxes (303) can rotate along with the outside of the cable body (8), preliminarily extruding and shaping the semi-finished cable body (8) when the rubber guide wheels (306) rotate, contacting with an adsorption sponge block (305) when the rubber guide wheels (306) rotate, smearing resin oil adsorbed in the adsorption sponge block (305) on the semi-finished cable body (8), and taking the resin oil as a medium for lubrication;

preheating and rolling: the rolled and shaped cable body (8) is subjected to temperature rise treatment by the electric heating pipe assembly (304), so that the PTEF raw material belt is in a semi-molten state, and then when the cable body (8) is subjected to continuous traction force of the take-up pulley structure (2), the cable body (8) sequentially passes through the middle position of each rolling roller (9) to completely extrude the cable body (8), and a gap between the PTEF raw material belt and the PI layer (13) is extruded, so that the PTEF raw material belt is completely attached to the PI layer (13);

cleaning and air drying: when the cable body (8) after the steps enters a cleaning section, the atomizing nozzles (7) are used for being connected with a cleaning water supply structure to spray cleaning water to the cable body (8), when the cable body (8) continuously moves, the cable body (8) is wiped by each group of cleaning rollers (10) to remove resin oil on the outer surface of the cable body (8), the generated cleaning water is discharged along with the dirt discharge end (402), the cleaned cable body (8) is wiped by the brush rollers (11) to remove the adhered cleaning water, and finally, the cable body (8) is discharged from the fixed box body (4), and under the action of the strong air fan (6), each strong air nozzle (602) is used for conveying high-flow-speed air flow to dry the surface of the cable body (8).

9. The seamless lapped cable with the polytetrafluoroethylene and polyimide composite tapes as claimed in claim 8, wherein the seamless lapped cable with the polytetrafluoroethylene and polyimide composite tapes is prepared by combining four production processes of automatic lapping treatment, rolling and shaping, preheating and rolling, cleaning and air drying.
