Strapping tool
Various embodiments of the present disclosure provide a strapping tool configured to tension metal strap around a load and, after tensioning, attach overlapping portions of the strap to one another by cutting notches into a seal element positioned around the overlapping portions of the strap and into the overlapping portions of the strap themselves.
1. A strapping tool comprising: a support; a tensioning assembly mounted to the support and movable relative to the support between a tensioning assembly strap-tensioning position and a tensioning assembly strap-insertion position; a gate movable relative to the support between a gate home position and a gate strap-insertion position; and one or more linkages operably connecting the tensioning assembly to the gate,
wherein a height of a strap-receiving opening defined between the gate and the support is a first height when the gate is in the gate home position and a second height greater than the first height when the gate is in the gate strap-insertion position, wherein the tensioning assembly is operably connected to the gate so movement of the tensioning assembly from the tensioning assembly strap-tensioning position to the tensioning assembly strap-insertion position causes the gate to move from the gate home position to the gate strap-insertion position, wherein the one or more linkages comprise a first linkage, a second linkage, and a third linkage, wherein the first linkage is fixedly connected at a first end to the tensioning assembly and pivotably connected at a second end to a first end of the second linkage, wherein a second end of the second linkage is pivotably connected to a first end of the third linkage, wherein a second end of the third linkage is fixedly connected to the gate.
2. The strapping tool of claim 1 , wherein the gate is mounted to the support.
3. The strapping tool of claim 1 , wherein the support defines a gate-receiving recess in which at least part of the gate is positioned.
4. The strapping tool of claim 1 , wherein moving the tensioning assembly from the tensioning assembly strap-tensioning position to the tensioning assembly strap-insertion position causes the second linkage to rotate, thereby forcing the gate to move to the gate strap-insertion position.
5. The strapping tool of claim 4 , wherein the tensioning assembly is pivotable relative to the support between the tensioning assembly strap-tensioning position and the tensioning assembly strap-insertion position.
6. The strapping tool of claim 1 , wherein the gate is repositionable relative to the one or more linkages to vary the first height.
