    摘要： A wire-handling arrangement (2) for receiving a series of preformed loops (4) of wire and for accumulating said loops of wire in order to form a coil of wire, comprising an essentially horizontal conveyor arrangement (6) configured to convey a rolled wire arranged in the form of overlapping loops from a wire providing member (8) to at least two coil-forming chambers (10) provided in the wire-handling arrangement.
    The conveyor arrangement (6) comprises a first conveyor line (12), a second conveyor line (14), a third conveyor line (16), and a switching conveyor member (18), wherein said first conveyor line (12) is arranged upstream said switching conveyor member (18) and said second (14) and third (16) conveyor lines are arranged downstream said switching conveyor line (18). Each of said second conveyor line (14) and third conveyor line (16) is provided with a coil-forming chamber (10) which is arranged downstream. The wire-handling arrangement (2) further comprises a control unit (20) configured to control said switching conveyor member (18) to be in a first position connecting the first conveyor line (12) to the second conveyor line (14), and in a second position connecting the first conveyor line (12) to the third conveyor line (16), thereby enabling said loops of wire (4) to be conveyed to the second conveyor line (14) or to the third conveyor line (16), respectively. The control unit (20) is configured to control said switching conveyor member (18) to be in a third position, and wherein in said third position the switching conveyor member (18) is connected to an upwardly open discard chamber (22) to convey loops of wire (4) to the discard chamber (22).

    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.
