    摘要: A binding machine comprising: —a feeding device for feeding a binding element (3) in the form of a wire or strap in a loop around one or more objects to be bound and subsequently retracting the binding element to draw it tightly around said objects; and —a laser welding device for forming a welded joint between a section at the leading end of the binding element and an adjoining section at the trailing end of the part (3a) of the binding element fed in a loop around said objects to thereby secure this part of the binding element in a loop around the objects. The laser welding device is configured to apply an identification marking on an outer surface of the binding element by means of a laser beam (14) emitted from a laser welding head of the laser welding device.

    摘要: A strapping machine comprising: —a feeding device for feeding astrap (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.

    摘要: A binding machine comprising a feeding and tensioning device (5) for feeding a binding element (3) in the form of a wire or strap around a space (4), and a joining device for forming a joint (8) between a first binding element section at the leading end of the binding element and a second binding element section at the trailing end of a piece of the binding element arranged in a loop in or around said space to thereby form a closed loop (11) of this piece of the binding element. The feeding and tensioning device is configured to exert a tensile force on the binding element in order to subject the joint to a tensile test. During this test, a gripping arrangement (30) is configured to keep the first binding element section secured in fixed position by engagement with a part (13) of the first binding element section located between the joint (8) and the leading end of the binding element.

    摘要: Method and apparatus for releasing a metallic binding element (10′) from a sheet metal roll (1), wherein an axial sheet metal edge (8) extends axially across the envelope surface (3) of the sheet metal roll, and wherein the binding element is secured to the sheet metal roll with pre-tension. The location of said axial sheet metal edge (8) or one or more axially protruding sheet metal edges at one of the gables of the sheet metal roll and the location of the binding element are detected to thereby establishing the location of a place where the binding element projects over a sheet metal edge under the formation of a gap (13′) between the binding element and the sheet metal roll. A laser beam (23) is focused onto a part (15′) of the binding element located above said gap in order to locally heat this part and thereby induce breakage of the binding element.

    摘要: A binding machine comprising: —a feeding device for feeding a binding element (3) in the form of a wire or strap around one or more objects and subsequently retracting the binding element to draw it tightly around said objects; and —a laser welding device (12) for forming a welded joint between a first section at the leading end of the binding element and an adjoining second section at the trailing end of the part (3a) of the binding element fed around said objects to thereby secure this part of the binding element in a loop around the objects. The laser welding device directs a laser beam onto an area (30) at the trailing end of said second section in order to reduce the tensile strength of the binding element, wherein the feeding device retracts the binding element in order to subject this area to tensile stress and thereby cause the binding element to be broken off.
