Manually actuated strapping unit for wrapping a steel strap around a packaged item

Abstract

A manually actuated transportable strapping unit for wrapping a tightening strap around a packaged item ( ) which unit includes a base plate ( ) which is provided with a supporting surface ( ) for arranging on a packaged item. The unit further includes a sealing device which is provided with a pivotable die-plate carrier ( ) which can be pivoted with respect to the base plate ( ), about a first bearing point ( ), which is provided in the region of a front end ( ) of the base plate ( ), from an open end position into a sealing end position and vice versa. A die-plate ( ) is arranged on the die-plate carrier ( ), which die-plate ( ) can be lowered by the pivoting movement of the die-plate carrier ( ) in the direction of a punch ( ) arranged in the base plate ( ) for which purpose a sealing-device lever ( ) is provided which can be pivoted about a second bearing point ( ) and whose pivoting movement can be transmitted to the die-plate carrier ( ) via a transmission element ( ) in a force-transmitting contact region of the die-plate carrier ( ). The unit includes separating means on the die-plate carrier ( ), with which the strap can be severed, and is provided with a tensioning device with which a strap tension can be applied to the tightening strap, the tensioning device having a tensioning lever ( ) with which a tensioning wheel ( ) arranged on a tensioning shaft ( ) can be actuated. At least in the sealing end position, a contact region of the transmission element ( ) with the die-plate carrier ( ) is arranged, with respect to a direction running at least substantially parallel to the orientation of the strap between the sealing device and the tensioning wheel ( ), approximately level with the separating means or behind the separating means.
