The invention relates to a wire binding device on a baler for straw, hay or the like from a knot hook, which is attached to a rotatable shaft, and a regulating rod, which is arranged next to the knot hook shaft and at its free end inwards onto the knot hook shaft bent towards and outward therefrom with the end of the regulating rod over the top of the knot hook lies.

In known wire binding devices of this type, the regulating rod ends in a knot hook shaft parallel or outwardly bent end piece, the free end of the rod next to the shaft and above the level in which the knotting hook rotates. This results in between the end of the regulating rod and the end of the knot hook at all of its angular positions a gap of considerable width. This gap has the consequence that sometimes Before starting the binding process, place one of the two wires to be twisted together between the regulating rod and knot hook slips out, so that a wrong tie occurs and the bale when leaving the press falls apart.

The invention has as its object to provide a wire binding device of the type mentioned in the To improve way that no disturbances of the binding process can occur. This task will according to the invention achieved in that the outwardly bent part of the regulating rod is so long is that it protrudes beyond the end of the knot hook at the beginning of the twisting of the binding wires. In this way, the two wires to be twisted together are already in place at the beginning of the binding process safe in an all-round closed mouth, which on the one hand by the knot hook itself and on the other hand, formed by the specially designed, outwardly extended end of the regulating rod is, so that the previously identified disadvantages of the known devices no longer occur can. The binding wires are held absolutely securely and cannot even partially slip back, which could result in a loose bond if the wires are still together let them twist together.

It is advantageous if the section of the regulating rod lying against the wire is cranked and at the same time to be formed arcuately curved in such a way that it partially hooks the opposite side of the knot includes and with its end the end of the knot hook at the earliest possible point in time of the binding process occupies overlapping position.

In an advantageous manner, the regulating rod can be designed to be flexible, with its cranked Seeks to place part of the knot hook shaft, but the regulating rod so far from the knot hook shaft it is removable that the two wire sections of the binding wire between the knot hook and regulating rod can be included.

Every 5, lies at the back. The shaft 24 begins to rotate, the two rods 34 are cranked at 34a (see FIG. 4) and the needle 29 goes into the position shown in FIG. 4 substantially in the middle of its length. Here- working position. Here, a new piece of wire 58 is arranged so that the upper end of the needle in the region of the end piece 47 brings the regulating rod 34 to a distance of 55 between the finger 22 and the other of the shaft 31 of the knot hook is removed and is held by stop 23. The wire section 48 is supported by a nose 37, which is moved out on one side of the hook opening by the needle over the currently still open bearing 38 of the rotatable knot hook shaft 31, so that it is tigt. The nose and the bearing are now attached to a supporting section 47 and 48 of the wire in part 39, which is held by the machine frame in the position shown in FIG. 5 on the side of the. The lower section 40 of the cranked straight holder 43 is located, which, however, is at the rear of the knot hook shaft 31 around the direction of rotation of the bending hook 33, based on the lier rod 34,
a short distance away. As soon as the fresh wire section 48 speaks through, the distance corresponds approximately to the wire diameter. The rod 34 needle 29 has been brought into the position in which is also equipped at its lower end 35 with a horizontal 65 for twisting together with the wire holder 41 already running from the right. The end part 47 of this device is ready, the holder 41 forms a cranked section 42, the shaft 31, the knot hook 33 clockwise to arcuate or circular segment-shaped substantially 180 ° from that shown in FIG

Starting position in the in F i g. 5 rotated position shown in which its end 44 is now the straight Part of the wire holder 41 in the FIG. 4 and 5 overlaps so that now the The mouth of the hook is closed and the two wire sections 47 and 48 are in the mouth.

If the knotting hook 33 with the associated shaft 31 now moves further into the position shown in FIGS. 6 and 7 Rotates position shown, the two wire sections 47 and 48 by the action of Inner surface of the curved hook 33 in the space 49 between the hook shaft 31 and the arcuate cranked part 43 of the wire holder 41 pressed.

With further rotation of the hook in the in the F i g. 8 and 9 positions shown are now the two wire sections 47 and 48 rotated around one another and thus form a fixed connection, wherein the flexibility of the regulating rod 34 ensures that the cranked part 42 of the wire holder 41 so far away from the shaft 31 that there is space for the wires twisted together, as shown in FIG F i g. 9 is shown.

As soon as the wire sections 47 and 48 have started to twist with one another, that will already be the case previously separated end part 47, which was held up until now, is released by the gripper finger 22 as a result, that it moves away from the one stop 23 (FIG. 10). The gripper finger rotates here clockwise. During this process there is no risk of the person who was held up until then Wire part 47 from part 48 separates. Then when the parts including the gripper finger 22 in the Fig. 11 and 12 shown end position move and the finger on the other stop 23 to When contact comes, the wire section 48 is separated, so that now the two free sections 47 and 48 of the twisted wire ends come free and the finished tied bale on the return of the knot hook in the in F i g. 3 can be ejected in a known manner. At the same time, the end of the wire severed from the piece 48 is removed from the finger 22 in the position shown in FIG and 12 clamped position shown and the vor

direction is ready to start a new binding process.
