ABSTRACT:
A tension control device (10 for tensioning filamentary material (F) being withdrawn from a spool (24) including, a mounting support (11), a spindle (24) receiving the spool and rotatably mounted relative to the mounting support, a control arm (13) rotatably mounted on a shaft (15) in operative relation to the spindle, a brake element (18) mounted on the control arm for selectively retarding rotation of the spindle, a guide roller (16) rotatably attached to the control arm over which the filamentary material being withdrawn from the spool is passed, and a break-away mounted (80) of the guide roller to provide tension relief when the tension in the filamentary material exceeds a predetermined value. A break-away signaling system (95) detects and signals angular movement of the guide roller relative to the control arm.
