Abstract
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.
Claims16
A strapping tool comprising:
- a support;
- a sealing assembly mounted to the support and movable via translatory motion relative to the support between a sealing assembly home position and a sealing assembly sealing position, the sealing assembly comprising a cover and multiple jaws connected to the cover and pivotable relative to the cover from respective jaw home positions to respective jaw sealing positions in addition to the sealing assembly being movable via translatory motion between the sealing assembly home and sealing positions;
- a conversion assembly comprising a linkage operably connected to the sealing assembly and configured to move the sealing assembly via translatory motion between the sealing assembly home position and the sealing assembly sealing position and configured to pivot the jaws between their jaw home positions and their jaw sealing positions, wherein the conversion assembly is configured to change an effective length of the linkage while moving the sealing assembly via translatory motion from the sealing assembly home position to the sealing assembly sealing position;
- and
- a drive assembly operably connected to the conversion assembly and configured to drive the linkage.

A strapping tool comprising:
- a support;
- a sealing assembly mounted to the support and movable relative to the support between a sealing assembly home position and a sealing assembly sealing position, the sealing assembly comprising multiple jaws pivotable from respective jaw home positions to respective jaw sealing positions;
- a conversion assembly comprising:
- a drive wheel comprising a drive shaft radially spaced from a rotational axis of the drive wheel;
- a linkage mount mounted to and rotatable relative to the drive shaft and comprising first and second fingers;
- a linkage mounted to and rotatable relative to the linkage mount and operably connected to the sealing assembly, wherein the linkage is configured to move the sealing assembly between the sealing assembly home position and the sealing assembly sealing position and is configured to move the jaws between their jaw home positions and their jaw sealing positions;
- and
- an effective-length-changing device fixed relative to the drive wheel, the linkage, and the linkage mount, wherein the effective-length-changing device comprises first and second stationary fingers;
- wherein the conversion assembly is configured to change an effective length of the linkage while moving the sealing assembly from the sealing assembly home position to the sealing assembly sealing position,
- wherein the effective length of the linkage is a minimum effective length when the linkage mount is in a first rotational position relative to the linkage and a maximum effective length when the linkage mount is in a second different rotational position relative to the linkage;
- and
- a drive assembly operably connected to the drive wheel and configured to rotate the drive wheel to drive the linkage.
