Strapping tool
View Patent ↗A strapping tool for tensioning a strap around a load, adhering the strap onto itself, and cutting a feed end of the strap, includes a body having a foot on which the strap is disposed during a strapping cycle. The body housing and/or forming a part of a tensioning element and including a welding element. One or more pneumatic motors tension the strap and drive the welding element. A pneumatic module is mounted to the body. The module has a compressed gas inlet to the module and is configured for controlling the flow of compressed gas to the one or more motors. A handle is mounted to the body and operably connected to the pneumatic module. The handle is configured for manipulating the tool and includes an actuator for permitting and isolating the flow of compressed gas to the pneumatic module. The handle is orientable so as to allow a user to select a desired handle orientation for operation of the strapping tool. At least one hold-down finger is mounted at about the foot to temporarily hold the strap on the foot during tool operation.
1. A strapping tool for tensioning a strap around a load, adhering the strap onto itself, and cutting a feed end of the strap, comprising:
a body having a foot on which the strap is disposed during a strapping cycle, the body housing a tensioning element and a welding element;
one or more pneumatic motors for tensioning the strap and for driving the welding element;
a pneumatic module mounted to the body having a compressed gas inlet to the module and configured for controlling the flow of compressed gas to the one or more motors;
an adjustable handle mounted to the body and operably connected to the pneumatic module; and
two biased hold-down fingers pivotally mounted at about the foot to temporarily hold the strap on the foot during and following strapping operation, each of the hold-down fingers having a curved free end, the free ends are curved upwardly to facilitate readily slipping the strap under the hold down fingers without undue effort, the hold-down fingers are disposed on opposing sides of the foot, the hold-down fingers are disposed on opposing sides of the tensioning and welding elements, wherein the hold-down fingers are configured to prevent the strap from slipping from the foot, not to rigidly lock the strap in place.
2. The strapping tool for tensioning a strap around a load in accordance with claim 1 including a biasing element and wherein the hold-down fingers are biased toward the foot, to a closed position.
3. The strapping tool for tensioning a strap around a load in accordance with claim 1 , wherein the hold-down fingers pivot about a pin.
4. The strapping tool for tensioning a strap around a load in accordance with claim 2 wherein the hold-down fingers pivot about a pin and wherein the pin is located between the biasing element and the free end.
5. The strapping tool for tensioning a strap around a load in accordance with claim 1 , wherein the handle is configured for manipulating the tool, the handle including an actuator for permitting and isolating the flow of compressed gas to the pneumatic module.
6. The strapping tool for tensioning a strap around a load in accordance with claim 5 wherein the actuator is located at an end of the handle.
7. The strapping tool for tensioning a strap around a load in accordance with claim 5 , wherein the handle is orientable so as to allow a user to select a desired handle orientation for tool operation.
