ABSTRACT:
Strap feeding and tensioning apparatus is provided for use in a strapping machine to feed steel or plastic strapping in a loop around an object to be strapped and tension the strap loop about the object, providing maximum gripping force on the strap and minimum marring thereof. The apparatus includes a motor-driven drive wheel geared to a feed wheel, the drive wheel and feed wheel respectively having circumferential strap-engaging surfaces which cooperate frictionally to grip the strapping therebetween and move the strapping in a tensioning direction in response to rotation of the drive wheel. The axis of rotation of the feed wheel is shiftable about a fixed axis to accommodate movement of the feed wheel toward and away from the drive wheel, tensioning of the associated strap exerting a resultant force on the feed wheel tending to effect movement thereof about the fixed axis in a direction to increase the frictional gripping force exerted on the associated strap by the feed wheel and the drive wheel. The axes of the drive and feed wheels lie in a plane disposed at a predetermined angle of less than 26 degrees with respect to a plane defined by the fixed axis and feed wheel axis. For use with steel strap the strap-engaging surfaces of the drive and feed wheels are substantially smooth and the predetermined angle can be as low as about 6 degrees. For use with plastic strapping the drive wheel has a toothed or knurled strap-engaging surface and the predetermined angle can be as low as about 12 degress.
