Effects of congenital deafness on central auditory processing

{PG,1 An apparatus is provided on a strapping machine frame adjacent a strap chute and adjacent a strap end gripping and sealing assembly and has a pivotably mounted strap guide arm and gripper for guiding the strap during feeding in a first, upper position and for gripping the strap when the arm moves downwardly away from the first position. A single, reversible, rotating drive motor is mounted for movement with the guide arm and powers a gear drive assembly which is engaged with the motor and movable therewith for (1) rotating feedwheels to feed the strap to form a loop when the motor is rotating in a first direction, (2) rotating the feedwheels to withdraw the strap to pretension the loop with a first predetermined tension when the motor is rotating in a second direction, and (3) rotating a high tension pinion gear when both (a) the motor {pg,2 is rotating in the second direction and (b) the tension in the strap exceeds the predetermined, first tension. During high tensioning, the pinion gear moves along a rack and pivots the guide arm out of the first position to a second position whereby a gripper is actuated to grip the trailing portion of the strap and pull the gripped strap, thereby drawing a higher, second tension in the loop.
