摘要

A strapping machine comprising:- a feeding device for feeding a strap (3) around one or more objects and subsequently retracting the strap to draw it tightly around said objects;- a welding device for forming a welded joint between a first section at the leading end of the strap and an overlapping second section at the trailing end of a piece (3a) of the strap fed around said objects to thereby secure this piece in a loop around the objects;- a support member (24) for supporting said overlapping strap sections during the formation of the joint, a recess (25) being provided in an upper support surface (26) on the support member; and- a pressing element (27) with a shape adapted to the shape of said recess, the pressing element and support member being configured to form a permanent bulge (30) on the first strap section by a press forming action between the pressing element and the support member.
