Abstract
A hand-held apparatus for tensioning a bundling strap about an item to be bundled having a motor and a rotatable output shaft coupleable to one end of an elongated external screw threaded shaft supported for rotation at its opposite end by an end cap. A guide block is adapted for linear reciprocal movement along the shaft between the hand-held unit and the end cap and has threads corresponding to screw threads on the shaft, the guide block having connected thereto means for gripping the bundling strap. A reversible power means energizes the hand-held unit and reverses or halts the direction of rotation of the output shaft upon exertion of a predetermined force upon the guide block.
