Taping lines for Polyimide-FEP

Line suitable for flat and round wires with precise synchronization of its taping heads by electric axis for the precise application of polyimide-FEP composite tapes (Apical®, Kapton®, Norton®, etc.) complete with thermal process for tape sintering. This machine can be equipped with two, three, or more concentric taping heads (both single motorized and fully electronic), also suitable for big cross wound spools or heavy pads thanks to the separate motorization of the tape spool.

The tape tension on each taping head is controlled by a dynamic dancer, which can effectively absorb any perturbation of the wrapping process over the flat wire, even at high speed.
This horizontal taping line is designed also for thermal treatment. The process is carried out by an induction pre-heater, infrared, radiant or molten salt bath furnaces. Subsequently the layer is consolidated by compacting units and cooling equipment for the complete adhesion of Polyimide-FEP composite tapes (Apical®, Kapton®, Norton®, etc.) on the conductor.

Details:

• torque-controlled or dancer-controlled pay-off and take-up units with standard wire guide or traversing movement to prevent any deviation from its axis;
• possibility to operate with more taping heads, of single or fully motorized type, also for big cross wound spools or heavy pads;
• the dynamic dancer, on the taping heads, maintains the tension of the tape constant and stable, for a perturbation-free process which is higly appreciated in case of “very flat” wires (high width/thickness ratio);
• fast pre-heating process with high-frequency heater and following compacting units of the cable by rollers;
• infra-red, radiant, or molten salt bath furnaces for sintering process with fully automatic opening and closing movement during start-stop phases;
• the most suitable combination of pulling units (one capstan, one or two caterpillars, or combined caterpillar/capstan) perfectly synchronized with the rotation of the head to control precisely the linear speed and the wire tension;
• cooling system with re-circulated cold water and air wipers for drying the wire;
• digital electronic control fully integrating all the units of the line, with possibility to be connected to the internal network and to internet for remote assistance;

 Other options:

• wire straightening with steel rollers and clearing device with brushes to ensure the best cable preparation;
• paper feeder installed on the take-up unit, suitable for the automatic deposition of a complete turn of paper interlay on the reel, during wire winding;
• in-line spark testers and other measuring devices for quality control;
• strobo-light automatically synchronized with the rotation of each head;
• tele-service system for remote connection by internet access.

All characteristics can be tailored according to the specific requirements of the customers.
