A strapping tensioning and sealing tool is disclosed herein. In one or more embodiments, the strapping tensioning and sealing tool includes a tensioning assembly, the tensioning assembly configured to apply tension to a piece of strapping; and a sealing assembly, the sealing assembly comprising at least one cam member, at least one crimping jaw member, and a motive power source, the at least one cam member operatively coupling the at least one crimping jaw member to the motive power source, and the at least one crimping jaw member of the sealing assembly configured to crimp a strapping sealing member so as to secure the piece of strapping around a package or bundle of items.

A strapping tool for tensioning overlapping sections of steel strap around a load and forming a notch-type seal in a seal element positioned over the overlapping sections of steel strap includes a body having a foot, a tensioning section and a sealing section. The tensioning section has a tensioner motor assembly operably mounted to the body. The tensioner motor assembly has an electrically powered tensioner motor. A tensioning wheel is operably connected to the tensioner motor. The sealing section has a notcher assembly that includes an electrically powered notcher motor operably mounted to the body. The notcher assembly includes a linkage and at least one pair of jaw elements. The linkage is configured to pivot ends of the jaw elements toward one another in a sealing cycle to form the notch-type seal in the seal element. A control system controls operation of the tensioner motor and the notcher motor. The control system is configured to operate the strapping tool in an automatic mode in which the tensioner motor and the notcher motor are sequentially actuated by action of the control system by an operator.

A portable binding device, comprises a main shaft and a chain, wherein ratchets are fixed at both ends of the main shaft and rotated in the same direction therewith, and the outer ring of the ratchet is provided with a gear ring. The middle part of the main shaft is installed with a compression bar which is perpendicular to the axis of the main shaft. One end of the chain is connected to the middle part of the main shaft, and the other end or the middle part of the chain is engaged with the gear ring. The device is simple in structure, may be convenient for carrying and may have a good binding effect and enhanced practicality.

A tool for sealing overlying courses of a strap that includes a gripping unit, a power supply unit detachably affixed to one end of the gripping unit, and a motor in the gripping unit. A cam is coupled to the motor and a notching unit is coupled to the cam by a plurality of linkages.

A manual binding tool in which, without transferring the fingers, tightening and cutting can be performed simply by gripping a pair of levers. The manual binding tool includes a tightening mechanism that pulls a projection tie portion that is passed through a head portion, a cutting mechanism that cuts the projection tie portion in the vicinity of the head portion, first and second levers, a tightening linkage mechanism that links the levers with the tightening mechanism in a state where the projection tie portion is pulled by gripping of the levers in a range within a predetermined angle, and a cutting linkage mechanism that links the levers with the cutting mechanism in a state where the projection tie portion is cut by gripping the levers beyond the predetermined angle. A switching mechanism alternatively allows one of the tightening or cutting linkage mechanism to operate based upon tightening force.

A belt pressing structure of a packing tool is provided. The packing tool includes a main body. The main body is provided with a belt pressing device, a belt winding device, and a power device. The belt pressing device includes a belt pressing seat. The belt pressing seat is pivotally connected with a handle. When in use, the user can hold the main body with one hand to lift the handle for the belt pressing device to form a passage, and a packing belt is inserted through the passage. After that, the handle is released, so that the packing belt is pressed and retained by the belt pressing device. The packing belt is tightened by using the belt winding device. Finally, the unnecessary packing belt is cut by the belt cutting device to complete the packaging operation.

The collar has a looped metal strap (10) and a transverse buckle (12) retained at the first end of the strap and forming, on the outer side of the first end, a passage (13) through which the second end (10B) of the strap can be inserted over the first end, the second end of the strap as inserted in this way being suitable for being indented so as to co-operate with at least one of the elements including the transverse buckle (12) and the first end (10A) of the strap, in order to be retained so that it is prevented from moving in the direction in which the diameter of the collar increases. The buckle (12) carries at least one radially projecting outer tab (20, 22), the tab having the shape of a hook having a stem carrying a head under which a recess is formed.

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.
