What the controlled bxw. Regarding the regulated and controlled cooling of whale wire or steel wire above the transformation point, but also the subsequent combination of the steel wire into a wire bundle, the wire sole conveying device and bundle forming device described in this context offers several advantages. The above-mentioned device consists of a wire loop conveyor arranged in a first height position, which immediately after the orphan of the wire transports this wire in the form of loops through a controlled and regulated cooling zone, in which the steel wire is then cooled down to the transformation or Oefugtumwanderung, as well as still from a second wire loop conveyor, which is arranged in a second height position and takes over the wire loops from the first wire loop * conveyor and then forwards them to a wire loop form device or to a wire loop form kemmer. From the two aforementioned wire loop conveyor directions, the wire is transported in the form of non-concentrating and overlapping or overlapping wire loops, whereby the two conveyor devices do not necessarily have to have the same speed, which in turn can lead to the fact that the wire loops in each wire loop conveyor device overlap or overlay each other with a different shape.

Any other unfavorable change in this procedure will also adversely affect the product. For example, it has been observed that stopping the main wire loop conveyor belonging to the cooling device necessarily interrupts the cooling process, which in turn has an unfavorable effect on the end product. Such a halt of the main conveyor occurs several times because in connection with the production of wire bundles or with the Difficulties are experienced when cutting the wire. For example, the wire can get caught in part of the device, causing a jam or a malfunction

is collected and processed into a bundle.

The one for the preferred embodiment of the subject matter of the invention The device 1 used for the controlled or the controlled and regulated cooling is similar to that with U.S. Patent No. 3,231,432 has been described and illustrated is. From FIG. 1 it can be seen that a looper 7 carries the steel wire 6 in the form of a continuous strand - namely with a temperature that is above the structural transformation point - is supplied and then in the form of overlapping or overlapping and non-concentric wire loops 2 on a conveyor device or a conveyor belt 8 drops. At the time when the wire loops 2 are placed on the conveyor or the conveyor belt 8, the temperature is still higher than that Temperature of the microstructure transition point. If these wire loops 2 are now through the conveyor belt 8 through the Device 1 guided for controlled and regulated cooling, then these wire loops are quickly and evenly cooled to above the transition point, the cooling being achieved by compressed air generated by the fans generated and is blown across the loops 2 upwards.

As can be seen from FIG. 1 and FIG. 2, after the structural transformation has taken place, the wire falls from the end of the conveyor belt or the conveyor device 8 through a loop pot 10 onto the second conveyor device or the second conveyor belt, where the wire then falls in the form of overlapping or superimposed wire loops K is deposited. From the second conveyor belt 3, the wire loops k are then fed to a bundle form or bundle form box 5, which the wire loops into bundles 13 of the desired

Dimensions, which are then transported away via a third conveyor device or a third conveyor belt I ^{1 *.}

Regardless of the conveyor device 8, which the cooling system runs through, the speed of the second conveyor belt or the second conveyor device 3 can be brought to a certain value via a suitable drive device 11 or even be stopped. As can be seen from FIG. 2, the aforementioned drive device 11 includes: a motor

with gear 26, a drive pulley 23 and a belt 24 _t ,

which connects the drive pulley 23 to the drive pulley 25 on the conveyor belt. With this conveyor or this The conveyor belt is the second conveyor belt 3i that transports the wire loops to the Bundforrakamraer or Bundformvorricftitung 5.

The band mold device or Bundforrakammer 5 to 19 of the StahldraMes in an overlapping and nichtkonzentrisehen For ~ sugeführt the wire loops * and then combined to the collars 13 with a desired or before _t ~~ planar Bundabraessung. As an example, a suitable waistband molding device or collar forming chamber 1 is those with FIG. To FIG. Been reproduced is selected, the connected US Patent 3 360 842 · ä

is the same as described.

FIG. 3 now shows that the drag belts 12 belonging to the collar forming device or collar font chamber 5 form the wire loops from the second conveyor 3 and then remove ale wire loops 19 evenly to the collar forming device or handed over to the bundle forming chamber 5. The aforementioned towing belts 12 are driven by a drive device (not shown here) at a speed that was «

209808 / 116A

May 30, 1971 - G S -

is slightly greater than the speed of the conveyor belt 3, which, however, is proportional to the speed of the conveyor belt 3. For example, drive chains that connect the drive wheels of the conveyor belt 3 to the drive wheels of the drag belts 12 could be used to drive the aforementioned drag belts 12. This then leads to the wire loops 19 being accelerated and being held essentially in a horizontal position until these wire loops 19 are released and can fall into the coil forming device or the coil forming chamber 5. While now the wire loops 19 in the collar forming device or in the band mold chamber 5 falls _e they extend such that gives a spiral shape. The wire loops 19 then finally fall over the guide element 16, where they are combined to form a wire bundle 13.

Once the desired or specified waistband dimension has been reached, then the conveyor belt 3 and also the drag belts 12 ″ are reversed to cut through or sever the wire Brought to a standstill. After the conveyor belt 3 and drag belts 12 have stopped, there is now, as shown in FIG. 3 shows, between the wire loops 19, which are still held by the sole straps 12 and which have already become one Bund 13 shaped wire loops a stationary and hanging wire section 21. Ss has now been found that this hanging wire section 21 after being stopped by the trailing belts 12 because of the arrangement of the wire loops 19 on the sole straps 12 the same case over and over again spiral assumes. Because now this spiral shape 12 of the hanging wire section has essentially durability and

209808/1164

May 30, 1971

can easily be determined, there is the possibility of providing a device with which the wire section can be severed or cut cleanly and accurately. Such a perfect cutting - and this with a minimum of wire entanglement and failure in severing the wire section 21 - is preferred Execution of the object of the invention accomplished in that a combination of horizontal plate 18, positioning arm 17 and scissors 20 according to the FIGS. K and KLg. 5a to Pig. 5c reproduced representations cooperates.

Now that the conveyor belt 3 and the drag belts 12 have been brought to a standstill, wherein the hanging wire section 21 has the shape of a spiral drop, the Horizontal plate 18 pushed into the collar forming chamber 5 (Fig. ^), where she then takes her operative position. The aforementioned horizontal plate 18 is made by a conventional device (not shown here) driven. From the horizontal plate 18, the wire section 21 is now brought into such a position in which the positioning pin 17 when it is about its pivot point 22 rotates, the wire section 21 can securely grip, whereupon the positioning arm 17 continues its pivoting movement and thereby brings the wire 21 onto the scissors 20, which this wire section - (in this context, reference is made to FIG. 5a to Fig. 5c referenced) - then severed or cut off. The positioning arm 17 is also driven by a conventional device (not shown here).

After the wire section 21 has been severed or cut off, the wire bundle is ejected and becomes the positioning rod 17 is moved back to its starting position, eventually

209803/1164

! / U May 30, 1971

the horizontal plate 18 is also withdrawn. The conveyor belt 3 and the tow bands 12 are put back into operation, and round the Fuhrungeelement 16 begins to form then a new coil of wire 13 when _t fall into the wire loops back to the Bundfοnovorrichtung or in the band mold chamber. The finished wire bundle 13 is brought onto a further conveyor belt Ik , which can be designed as any suitable conveyor belt, and is then transported away.

During the standstill of the conveyor belt 3, however, the controlled and regulated cooling device 1 and the conveyor belt 8 assigned to it continue to operate, in which case the wire loops 2 are temporarily stacked in a wire loop stacker 10 of the conveyor belt 3 until the conveyor belt 3 starts up again. To compensate for the standstill period, the conveyor belt 3 can be transported away. Port of the wire loops stacked in the wire loop stacking chamber 10 are put into operation at a higher speed compared to the conveyor belt 8, whereupon the speed of the conveyor belt 3 can be reduced or reduced to the usual Gesehwindig- W after removal of the stacked Drahtschiin conditions.

The problems which this invention had to solve were the difficulties in providing a device for collecting and bundling steel wire in the form of overlapping and non-concentric wire loops 2 as they emerge from the controlled cooling device 1. Because any delays or any standstill in the conveyor belt 8 can lead to unpredictable thermal changes in the wire, with its properties also no longer being uniform.

As for the problems, this invention now offers two Solutions. First, by providing a device to stop or slow down the wire loops, the be transported to the coil forming device or to the coil forming machine 5, the controlled or controlled and regulated cooling process does not have an unfavorable effect, so that what wire 2, which is cooled to above the structural transformation point, then Damage cannot occur if there is a standstill in the collar forming device or in the collar forming chamber 5 or xu a slowdown comes. In addition, the wire section 21 intended to be cut is at this point in time - i.e. after reaching the desired and specified dimensions of the wire bundle 13 - in such a position, which ensures a safe separation or cutting process, which in turn reduces the incidence of disabilities, which can arise from an improperly cut wire end 21 can be avoided.

The discussion of the use of this invention in the devices is intended to demonstrate the effects of this invention on specific devices. Another device with controlled and regulated cooling could also be used, but also another device with which the wire is combined into coils. As to these designs, those skilled in the art will certainly make numerous changes to the designs discussed ^; ;> irur, _o know the subject matter of the invention. The main advantages, however, lie in the systems in which the wire is arranged in overlapping and non-concentric rings at the point in time when the wire is combined, and in which the controlled cooling cannot be interrupted without causing harmful thermal effects Effects on the steel wire can.
