Abstract
A device for laying a thin metal wire in a straight line on the surface of the thermoplastic film of a laminated glass pane. A rotatable mounting is provided for the wire supply reel, a heated pressing roller presses the wire into the thermoplastic film and a guide device guides the wire between the supply reel and the pressing roller. The supply reel is coupled in rotation to an electromagnetic brake having an adjustable braking torque and a wide control range for the braking torque. The electromagnetic brake is preferably a magnetic powder brake.
