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.

The collar comprises 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 said 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 comprising 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.

A tension clamp (19) includes a band (20) surrounding an object to be fastened and a buckle (21) arranged on the inner band end portion (22) and surrounding the band (20), with the outer band end portion (23) extending through the buckle (21). A tool for mounting the tension clamp includes a holding device for holding the buckle (21) along with the band (20) surrounding the object to be fastened, a tensioning device for tensioning the band (20) round the object to be fastened by applying tension to the outer band end portion (23), a locking device (50) for locking the buckle (21) on dem band (20), and a severing device for cutting off excessive band length. The locking device (50) has plier jaws (54) adapted to be inserted into lateral windows (25) of the buckle (21) for deforming side edge portions (24) of the other band end portion (23).

A packaging device includes a conveyance mechanism, a guide portion and a control portion. The control portion is configured to cause a first section of a film to be bonded to a base, cause the conveyance mechanism to convey the base toward a downstream side in a conveyance direction, move the guide portion along a movement path, cause the conveyance mechanism to convey the base toward the upstream side, cause a second section of the film to be bonded to the base, and cause the film to be moved in an opposite direction to a feeding direction at any time during a period after the first section is bonded to the base and before the second section is bonded to the base, the feeding direction being a direction in which the film is fed out when the base is conveyed.
