    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： A method and apparatus for a two speed strap take up usable in a strapping machine. The two speed strap take up apparatus generally comprises a high speed roller assembly (20) driven by a high speed drive shaft (28), a low speed roller assembly (40) driven by a low speed drive shaft (48), a shaft rotation reduction assembly (56) interconnecting the high speed drive shaft (28) and the low speed drive shaft (48), and a roller clutch assembly (220) inter-connecting the shaft rotation reduction assembly (56) and the low speed drive shaft (48). An input clutch assembly (250) may inter-connect the high speed drive shaft (28) and an input drive means. In operation, a strap (12) is disposed between and frictionally engaged by a high speed roller (22) of the high speed roller assembly (20) and a low speed roller (42) of the low speed roller assembly (40). The low speed roller (42) is then driven in rotation by the high speed roller (22). When a first tension is applied to the strap (12), the high speed roller (22) slips relative to the high speed drive shaft (28) until the roller clutch (220) inter-connecting the shaft rotation reduction assembly (56) and the low speed drive shaft (48) engages and rotates the low speed drive shaft (48) at a reduced rotation rate relative to the rotation rate of the high speed drive shaft (28). The strap (12) is now driven by both rollers (22, 42) at the reduced rotation rate as the high speed roller (22) slips relative to the high speed drive shaft (28). When a second tension, greater than the first tension, is applied to the strap (12), the low speed roller (42) slips relative to the low speed drive shaft (48) at which time the strapping machine may perform additional functions on the strap (12) such as securing it around a package.

    摘要： An improved power strapping machine (20) comprising a strapping device (24) and a soft touch package compression device (20). The strapping device (24) includes plurality of coils (40,42) for supplying strap (38) to a guide apparatus (32). A chute apparatus (36) for routing strap (38) around an article or package (22) to be strapped is connected to the guide apparatus (32). The machine includes sensors and a control circuit adapted to operate the machine continuously without the need to stop production, since when one coil is out of strap or a misfeed occurs, the machine will automatically load another coil of strap and continue strapping packages. The soft touch package compression device (26) uses pneumatic-drive chain drive systems (150,152) for moving soft belts (154) up and down. The soft belts compress the package so that the strapping device can place a tight strap around the package.

    摘要： A length of thermoplastic strapping for use as strap disposed in a loop around an article with overlapping strap portions arranged face-to-face and welded together, has a first layer (10) including a first material and a secoind material (12) carried by the first layer (10). The second material (12) ensures the creation of a plurality of cavities or discrete volumes (50) in the first material in the weld. The second material may be a layer of material with pre-formed cavities or may be a particulate foaming agent (12) located on or in the first layer (10). The welded joint from such strapping includes a resolidified region (8) formed by fusing at least part of the thickness of each strap portion. The resolidified region (46) includes a solid phase of the first material and a plurality of discrete volumes (50) defined in the resolidified region from which the fist material is absent and which are distributed in the first material across the width and thickness of the resolidified region (46) at least adjacent each end of the resolidified region (46).

    摘要： A method of welding at least two layers (18, 20) of thermoplastic material, e.g. polyethylene terephthalate or polyporopylene, and a weld (30) so produced comprises directing a jet of hot gas from a nozzle (10), through a hole (16) in an inlet mask (16), and against the layers (18, 20). The layers (18, 20) are backed by an outlet mask (22) having a hole (26) and serving as a heat sink. The inlet mask (16), the layers (18, 20), and the outlet mask (22) are clamped together. A transverse weld (30) is formed entirely of the material of the layers (18, 20). The weld (30) has a columnar shape with an enlarged end (32′), which is cold-headed. The opposite end of the weld is level with or depressed with respect to marginal surfaces of the adjacent layer (18, 20). If the material is crystallizable, the weld may be more crystalline than other portions of the layers.
