Document Type and Number:
Japanese Patent JP4663907
Kind Code:
B2
Abstract:
A strapping machine (10) for positioning a strap material (S) around an associated load and tensioning the strap material around the load includes a frame for supporting the load, a chute (16) positioned on the frame for receiving the strap material (S) and orienting the strap material around the load, a strap supply (18) and a strapping head (12) for extracting the strap from the supply, feeding the strap through the chute around the load, passing the strap from the chute around the load, retracting and tensioning the strap. The strapping head includes feed rollers (22a,22b) and retraction rollers (24a,24b) for feeding and retracting the strap and a winder (28) for tensioning the strap around the load. The winder (28) is positioned between the feed and retraction rollers and the strap supply. The winder includes a rotating head portion having a stationary element (30) and a pivotal element (32). The stationary and pivotal elements each define an outer surface around which the strap material is wound and a slot (34) therebetween for receiving the strap material (S). The stationary and pivotal elements each further define a gripping portion (44,46) at about respective ends opposingly facing one another. The pivotal element (32) is pivotal between an open position in which the gripping portions (44,46) are spaced from one another and a closed position in which the gripping portions cooperate with one another to engage and secure the strap material (S) therebetween. The winder (28) is rotatable from a home position in which the pivotal element is in the open position and a position in which the pivotal element is in the closed position to exert a tension in the strap.
