A machine for tying together mutually crossing rods with the aid of wire-ties. The machine includes a device (8, 9) having a curved wire-guide surface which is intended to be positioned so that the guide surface will essentially surround a rod intersection point on three sides of the mutually crossing rods (6, 7). The machine also includes means (18-20) for feeding at least one wire to this device, so that the wire will be bent by the guide surfaces into a wire-stirrup which surrounds the intersection point on three sides, and a rotatable twisting head by means of which the free legs of the stirrup are twisted together on the fourth side of the intersection point. The machine is characterized in that it also includes a feed tube (18) for feeding severed, straight wire-sections (16) of predetermined lengths, the lower end of the feed tube is located above an opening in the twisting head positioned in line with a part of the guide surface. Mounted for axial movement in the tube is a means which functions to press wire-sections introduced into the tube in a downward direction and displace the wire-sections along the guide surface, such as to form a wire-stirrup. |
