Abstract: 1,236,984. Bundling machines. MAKEEVSKY ORDENA LENINA METALLURGICHESKY ZAVOD IM. S.M. KIROVA. 15 Oct., 1968, No. 48860/68. Heading B8C. A machine for binding articles or piles of articles with wire includes a device for girdling an article or piles of articles with a piece of wire and a device 6 for twisting together the ends of the wire after girdling, the girdling device having two symmetrically arranged quadrilateral linkages 35 each of which includes a cantilever extension of a link forming the side opposite the fixed side of the linkage, the extensions being adapted to trap opposite ends of the wire so that subsequent movement of the linkages may effect girdling and each carrying on its end a catch 36 for the wire, each extension serving as a guide for a rod 37 one end of which slides along the guide and the other end of which is hinged to the fixed side of the linkage, the length of each rod being such as to allow the catch and associated end of the rod to be drawn together when the linkage has completed the girdling operation and to allow the twisting together of the ends of the wire to be effected. As shown, wire passes through a conduit 46 to feeding rollers 7 and straightening rollers 8 driven via a clutch 10 and .worm and wheel transmission 11 by an electric motor 9, the lower rollers being secured in the body of a reducing gear and the upper rollers being mounted on frames 12, 13 capable of limited rolling movement about the worm shaft 14, the starting and stopping of the rollers being affected periodically by a pneumatic cylinder 17. The wire passes through shears 18, connected to the cylinder 17 by a lever 19 and the rod 20, and a length of the wire cut off passes through a hole in a tag, taken from a set of tags 29, and to a conduit 21 secured by a lever 22 to a shaft 23 on which is carried a crank 24 coupled with a rod 25 and lever 26, the latter being actuated by a roller 27 co-operating with a cam 28. The linkages including movable links 35, 35<SP>1</SP> and 3511 and an immovable link, cantilever parts of the links 35 carrying the catch 36 for the wire and serving as a guide for the rods 37 which are slidable along the guide and hinged to the link 35<SP>1</SP>. The arch-like reciprocating motion of the linkages is imparted thereto by an electric motor 38 via a reducing gear 39, crankshaft 40, connecting-rod 41 and gears 42. The wire twisting device 6 includes an element 43 having spirally extending members and is secured on a shaft 44 rotated by gears 45 on the crankshaft 40. The conduit 21 carrying the length of cutoff wire is turned to a vertical position so that the wire, while the linkages are at the forward position thereof, falls on to a stop 47. By operation of the motor 38, the linkages travel: rearwardly to draw the wire towards the device 6, the ends of the wire being clamped by the article to be bound; the ends of the wire are caught in the device 6 and twisted together. The machine may be installed on a self-propelled trolley.
