Ridgway W-LAP



Designed for the precision winding of large looped coils

Ridgway W-LAP Heavy Duty Loop Winding Line
W-LAP Heavy Duty Loop Winding Beam

This automated winding line produces large conventional coil loops. Capable of accepting multiple conductors which are passed through gathering boxes and conductor guidance systems, the correctly orientated and bunched conductors are either taped by the 'Squirrel' Tape Turner or guided directly into the loop winding beam. The loop winder has servo driven, adjustable pins which are automatically set to pre-programmed positions to produce a range of variable loop lengths.
