ABSTRACT:
A power driven dereeling apparatus comprising a supporting frame which carries for rotation thereon a table adapted to carry a reel of strand material coiled thereon. An electric motor is connected to rotate the table. A device is provided for sensing the tension of a strand being drawn off the reel, this device being fixedly disposed relative to the frame. The device further includes a cam roller engageable by a strand being drawn off the reel, the roller being movable between first and second positions in response to a predetermined change in tension of such strand. An electrical switch is disposed to be responsive to movement of said cam roller to said first position due to an increase in tension for energizing the aforesaid motor. This in turn causes rotation of the table and reel mounted in a direction to pay strand material off the reel. If withdrawal of strand from the reel is stopped or if the table rotation pay off speed exceeds the speed of the machine consuming strand of material, the slight overrun of the table and reel will relax the tension on the strand, thereby permitting the cam roller to move to its second position to thereby actuate the electrical switch oppositely. This results in deenergizing the motor and energizing an electrical brake to prevent reel overrun and disorientation of the reel of material.
