A strapping head for a strapping machine includes a containment frame for housing at least a strap launch/rewind path defined by a launch/tensioning assembly including a plurality of driving wheels of the strap, a welding assembly and a gripping and cutting device including locking grippers, a moving abutment plate and a cutter, the driving wheels of the launch/tensioning assembly being brought into rotation by a first actuation motor, wherein all of the launch/tensioning assembly, welding assembly and gripping and cutting device have driving members driven into movement through a single linear cam apt to move alternately in the longitudinal direction through a second actuation motor and having cam profiles both on an horizontal plane and on a vertical plane, and the linear cam is actuated by the second driving motor being integral in rotation with screwed spindle transmission elements mutually cooperating with screw nut elements integral with the linear cam.
A strapping head for a strapping machine, comprising a containment frame (C) suitable to house at least a strap launch/rewind path defined by a launch/tensioning assembly (1) comprising a plurality of driving wheels (10, 11, 12, 13, 14, 15) of said strap, a welding assembly (3) and a gripping and cutting device (2) comprising locking grippers, a moving abutment plate and a cutter,
The strapping head as in 1, wherein said screwed spindle and nut transmission means are in the shape of a helical-groove screwed spindle (53) engaged with said screw nut transmission means in the shape of a recirculating ball body (54) integral in translation with said linear cam (4).
