Abstract: A binding machine including a feeding and tensioning device for feeding a binding element in the form of a wire or strap around a space, and a joining device for forming a joint 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 the space to thereby form a closed loop 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 is configured to keep the first binding element section secured in fixed position by engagement with a part of the first binding element section located between the joint and the leading end of the binding element.

Abstract: 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 cut off the binding element at said trailing end to thereby release said part (3a) of the binding element from the remaining part (3b) of the binding element.

Abstract: 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.

Abstract: A retainer unit for use in a wire binding machine in order to retain and subsequently release a wire during the tightening thereof around one or more objects. The retainer unit comprises: a wire retaining member pivotable, under the action of a press force exerted by a wire, from an advanced wire retaining position to a retracted wire releasing position; a blocking mechanism moveable from a blocking position, in which it prevents the wire retaining member from being pivoted to the wire releasing position, to a non-blocking position, in which it allows the wire retaining member to be pivoted to the wire releasing position. The blocking mechanism is arranged to move to the non-blocking position under the effect of said wire when the wire reaches a given inclination towards a wire contacting part of the wire retaining member. The invention also relates to a wire binding machine comprising several such retainer units.

Abstract: A retainer unit (1) for use in a wire binding machine in order to retain and subsequently release a wire during the tightening thereof around one or more objects. The retainer unit comprises: a wire retaining member (10) pivotable, under the action of a press force exerted by a wire, from an advanced wire retaining position to a retracted wire releasing position; a blocking mechanism (20) moveable from a blocking position, in which it prevents the wire retaining member from being pivoted to the wire releasing position, to a non-blocking position, in which it allows the wire retaining member to be pivoted to the wire releasing position. The blocking mechanism is arranged to move to the non-blocking position under the effect of said wire when the wire reaches a given inclination towards a wire contacting part (11) of the wire retaining member. The invention also relates to a wire binding machine comprising several such retainer units.

Abstract: An arrangement for transporting wire coils and similar products in a rolling mill or the like, including conveyor system, along which a load carrier, carrying the wire coil, is intended to be conveyed, and the conveyor system having a large number of modules, placed in series, and each one having a driving unit and a plurality of the wheel pairs, which are driven by the driving unit, and which are intended to bring the load carrier forwards or backwards. Each module has such a design that it can be used when transporting horizontally and vertically arranged wire coils. The driving unit includes a motor which is intended to drive one of the wheel pairs, the driving force from his wheel pair being intended to be transmitted to an adjacent wheel pair by means of a transmission belt.
