    摘要： An apparatus is disclosed which is mountable in a strapping machine frame adjacent a strap chute and adjacent a strap end gripping and sealing assembly. The apparatus 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. The strap is both fed into the strap chute and subsequently pre-tensioned by a pair of coacting feedwheels. A high tension pinion gear is mounted for rotation on an axis which is fixed relative to, and movable with, the strap guide arm. The pinion gear engages a rack member which is secured on one end to the strapping machine frame and which transmits the reaction force from the pinion gear to the strapping machine frame when the pinion gear is rotated in engagement with the rack. 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 the feedwheels to feed the strap 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 the high tension pinion gear when both (a) the motor 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 the rack and pivots the guide arm out of the first position to a second position whereby the 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.

    摘要： Disclosed is a steel strip packing apparatus. The steel strip packing apparatus includes: a pressurization device including a base and a pressing board disposed opposite to the base, the base having a placement position for disposing the fuel cell stack, the pressing board being configured for pressurizing the fuel cell stack disposed at the placement position; a steel strip shaping device disposed at the base and configured for guiding the first end of the steel strip from one side of the fuel cell stack to the other side of the fuel cell stack along a first direction, and configured for bending the first end and the second end of the steel strip in a second direction perpendicular to the first direction; two steel strip tensioning devices disposed at the base, located respectively on two sides of the placement position in the first direction, and configured for tensioning respectively the first end and the second end of the steel strip along the second direction; and a welding device configured for welding respectively the first end and the second end of the steel strip to the fuel cell stack.

    摘要： The disclosure relates to an automatic bundling tool device, ATD (1), for bundling a bundling good (2) by means of an one-piece-tie, OPT (14), with automatically tightening the OPT (14) by the ATD (1), in particular for bundling a bundling good (2) by means of a cable tie with automatically tightening the cable tie by the ATD (1), comprising a tightening mechanism (10) with a tightening gear unit (11) with a tightening gear (11a), and with a tightening roller unit (12) with two tightening rollers (12a, 12b), forming a gap (13) in between tightening gear (11a) and tightening rollers (12a, 12b), where the gap (13) is configured to hold a strap (14a) of a respective OPT (14) processed by the ATD (1), and the tightening gear (11a) of the tightening gear unit (11) comprises teeth (11b) which are configured to fit into a serration (14b) of the OPT strap (14a); wherein the tightening roller unit (12) comprises a lever (12c) with the two tightening rollers (12a, 12b) being arranged on the lever (12c) in a first end section (12') of the lever (12c), a turning point (12d) of the lever (12c) being arranged in a middle section (12") of the lever (12c), and an adjustment element (12e) of the tightening roller unit (12), which is configured for adjusting a width (w) of the gap (13), being in mechanical contact to a second end section (12‴) of the lever (12c), which is arranged oppositely to the first end section (12') along a main extension direction of the lever (12c) so as to overcoming the limitations of the known state of the art, in particular being capable of reliably tightening one-piece-ties (14) with increased tolerance with respect to the one-piece-tie strap thickness.
