A sealing tool for forming a joint in a seal positioned on overlying courses of strap includes a body, a motor and drive train housed, at least in part, in the body, a power supply and a sealing assembly mounted to the body. The sealing assembly is operably coupled to the motor. The sealing assembly includes at least one jaw having a pair of opposing jaw elements. Each jaw element has two edges for cutting into the seal and the courses of strap and forming a bent tab. The jaw element edges are configured to cut into the seal and the courses of strap material at different distances into a width of the seal and strap material. A method for forming seal and a seal formed by the tool and method are disclosed.

A rebar binding machine comprises a curl guide that causes a wire to curl, a torsion part including a torsion shaft for twisting the curled wire, and a pair of grips that can be grasped by an operator. The grips are provided to the two axial sides of the torsion shaft as viewed from the operator side when the operator grasps the grips to perform an operation, and it is possible to change the height of the grips in the axial direction of the torsion shaft.

A strapping tool is disclosed herein. In one or more embodiments, the strapping tool includes a motive power source and a sealing assembly. The sealing assembly includes a first punch and a die, the first punch and die configured to crimp or cut a notch in a strapping seal member and/or a piece of strapping so as to secure the piece of strapping around a package or bundle of items.

A strapping device including a tensioner operable to apply a strap tension to a loop of wrapping strap, a friction welder operable to produce a friction weld connection at two areas of the loop of wrapping strap disposed one on top of the other, a motor operable in a first rotational direction to drive the tensioner and in a second opposite rotational direction to drive the friction welder, and a control device. The control device is configured to, in response to receiving a first designated input: (1) operate the motor in the first rotational direction to drive the tensioner until a predetermined strap tension is reached in the loop of wrapping strap; and (2) afterwards, automatically operate the motor in the second different rotational direction to drive the friction welder to produce the friction weld connection.

An electrically powered strapping tool for tensioning and forming a sealless joint in overlapping sections of steel strap around a load includes a body having a foot, a tensioning assembly operably mounted to the body, the tensioning assembly having an electrically powered motor and a tensioning wheel operably connected to the tensioner motor. The tool includes a sealing assembly operably mounted to the body, the sealing assembly having an electrically powered motor and a sealer operably connected to the electrically powered motor. A control system controls operation of the tensioning assembly and the sealing assembly to operate the strapping tool in an automatic mode in which the tensioning assembly and the sealing assembly are sequentially actuated by a single action of the control system by an operator, and in a manual mode in which the tensioning assembly and the sealing assembly are sequentially actuated by multiple actions of the control system by the operator.

A bundling device comprises a frame, and a wire bending device and a wire twisting device each mounted to the frame. The wire bending device bends a bundling wire into an open ring to partially surround an object to be bundled, and guide the bundling wire into the wire twisting device. The wire twisting device twists two opposite end segments of the bundling wire together to bundle the object.

This publication describes automatic bundling tool devices capable of tightening one-piece-ties with increased tolerance with respect to the thickness of the one-piece-tie (OPT) strap. In an aspect, disclosed is a bundling tool device that includes a tightening mechanism with a tightening gear unit with a tightening gear, and with a tightening roller unit with two tightening rollers, forming a gap in between tightening gear and tightening rollers. The gap is configured to hold a strap of a respective OPT processed by the device. The tightening gear includes teeth which are configured to fit into a serration of the strap. The tightening roller unit includes a lever with the two tightening rollers being arranged on the lever in a first end section of the lever, a turning point of the lever being arranged in a middle section of the lever, and an adjustment element of the tightening roller unit.

A strapping tool is disclosed herein. In one or more embodiments, the strapping tool includes a motive power source and a sealing assembly. The sealing assembly includes a first punch and a die, the first punch and die configured to crimp or cut a notch in a strapping seal member and a piece of strapping so as to secure the piece of strapping around a package or bundle of items.

A rotary translational strapping apparatus and strapping method thereof are provided including a support frame, a rotary module, and a translational strapping module, the rotary module includes a rotary guide, a rotary frame, and a first driving mechanism, the rotary guide is disposed on top of the support frame, the rotary frame is rotatably disposed on the rotary guide, the first driving mechanism is used for driving the rotary frame to rotate relative to the rotary guide. The translational strapping module includes a sliding mount, a strapping head, a strapping chute, and a second driving mechanism. The sliding mount is slidably disposed on the rotary frame.
