Abstract
A tensioner for an armature winder which significantly reduces instantaneous increases in wire tension during winding or lead connection. System controls control the drag of a hysteresis brake, monitor wire tension via a load cell, and control a dancer arm's position through limit sensors and a closed-loop proportional valve (which regulates the pressure within an air cylinder coupled to the dancer arm). These system controls significantly reduce instantaneous increases in wire tension during winding, during the start of winding, and during lead connection. A wire breakage detection device also monitors the wire during winding and signals the system controls if wire breakage is detected. Upon such detection, a rapid discharge valve discharges the air cylinder, and flyer arm rotation is halted prior to the wire becoming unthreaded from the flyer arm.
