Strapping apparatus

A strapping apparatus for strapping goods with a band in a tensioning direction, the strapping apparatus having:

• a tensioning device operatively connected to a tensioning drive and arranged to tension the band, the tensioning device having a rocker arranged opposite a tensioning wheel, the rocker being mounted pivotably on a rocker axis, the tensioning wheel and the rocker being adapted to move towards each other to clamp the band therebetween;
• a closure device for sealing two portions of the band;
• and
• a plurality of rewinding locks for fixing the band on the strapping apparatus,
• wherein the rocker is provided with two abutment rollers each mounted rotatably on an axis, the axes being aligned substantially parallel to the rocker axis of the rocker, and, with regard to the tensioning direction, one of said axes being arranged upstream of the rocker axis while the other being arranged downstream of the rocker axis.

• a hand lever;
• a base plate;
• and
• a welding device for sealing two portions of the band, the welding device having:
• a support positioned on the base plate of the strapping apparatus via a rotational spindle;
• a lever;
• a driving mechanism mounted on the support and having a driving motor shaft acting upon one end of the lever;
• an eccentric operatively connected to the motor shaft and the lever for transmitting an eccentric movement to the lever;
• a welding shoe coupled to the other end of the lever, the lever being mounted pivotably on a pivot spindle positioned on the support so that the eccentric movement results in an oscillating reciprocating movement of the welding shoe;
• and
• a transmitting element situated on the rotational spindle and operatively connected to the lever for transmitting a pivoting movement of the hand lever of the strapping apparatus to the welding shoe.
