Abstract
A strapping machine for positioning an associated strap material around an associated load and tensioning the strap material around the load, the strap having a width, the strapping machine comprising a frame for supporting the load, a chute positioned on the frame for receiving the strap material and orienting the strap material around the load, a strap supply, and a strapping head. The strapping head extracts the strap from the supply, feeds the strap through the chute around the load, passes the strap from the chute around the load, retracts and tensions the strap, and seals the strap to itself. The strapping head includes a plurality of sealing elements and a gripper. The gripper is positioned at an upstream location from the plurality of sealing elements. The gripper has a floating element and a stationary element. The floating and stationary elements each include base surfaces. A plurality of teeth extend from one of the floating and stationary elements and a plurality of channels is formed in the other of the elements. The teeth and the channels are configured to secure the strap therebetween when the gripper is actuated, such that when the gripper is actuated, the teeth, in conjunction with the channels, form substantially centrally located, localized deformations in the strap extending across a portion of the strap width.
