must change automatically, the degree of stretching, so that the country product as smooth as possible. Expressed differently , if the so-called good at a certain point in time has a thickening, the degree of stretching can be increased accordingly at the moment in which this thickening is stretched (and vice versa).

The moment in which the test device a Measures cross-sectional change, now does not correspond to the eye * Look, in which the change gear determining the degree of stretching has to be effective, due to the time which the material to be treated needs to travel the distance between the sensing device and the drafting system. These temporal shift between these two moments has a certain value, which corresponds to a precisely determined feed rate of the fed goods. This time can theoretically but it is better to be empirical determined by systematic experiments.

The cross-sectional changes must therefore be in a Delay device (or memory device) registered which will later be read by a device, which the change gear corresponding to that of the storage device registered information.

Bs is already such a delay or Storage device with a rotatable drum known which carries on its circumference a certain number of bars, which are conventionally used parallel to the axis of rotation of the drum. These Rods are adjusted axially by ropes which act on their sins and by means of the thickness of the item to be treated

locking key device are actuated. The so in the > StSbe registered are then made by bringing the rotation of the drum to the reading point, where it is initially in its position by a fixed locking device be locked, whereupon they operate a change gear controlling parts.

This known delay device has ge-'wisse Compartments. It is complicated and only affects a small number of stumps. In addition, the registration and Reading parts are not suitable for sudden changes in cross-section. Furthermore, the known devices often jam and their locking systems are generally too weak.

The invention aims to remedy the above disadvantages. ,

According to the invention, the setting is made for this. and the reading of the stewards by a pair of Parts, each of which can pivot individually around an axis that is, for example, perpendicular to the axes of the bars. and with one end of the Rods cooperates, these parts being connected to each other by an elastic member which they each other to nShe-rn and against the corresponding sin of the "StSbe zu seeks to print, at least one of these parts directly from the determining the thickness of the item to be treated Test device is actuated or directly the device actuated to control the gearbox »

G-emäes a further feature of Brfindung are the two parts of each pair of parts for Sinetellung or reading the cash triers tSbe with the TAAT "bz * · Ablssevorriohtung connected via a balance lever.

(Depending on a further characteristic of the invention every register rod works together with a locking element for its locking in the registration position, which is permanently assigned to him and him during his rotary movement accompanies him, which brings him to the setting or reading in front of the parts.

, ■ According to a further characteristic of the invention the registration tabs are combined in pairs, with the two bars of each pair with the same locking link cooperate

& ema * ss a further characteristic of the invention the locking links with the registration rods are in or out of a singing handle by a radial translation movement brought, whereby the engagement is preferably necessarily produced by a pressure exerted on these limbs,

provided stretching device is fed. Tucked load device is shown here schematically by a roller 13, which sits at one end of a pivot lever 14, the other find is hinged to a handlebar 15, which in turn is hinged to an extension 16 of the guide 6

The roller 13 is pressed by a spring 17 against the item 11 to be treated

In this embodiment, the position of the guide 6 is determined by the position of the roller 13, ie. through the thickness of the item to be treated 11. Hie StSbe 1 are pressed against the guide 6 by the action of the spring 10, which presses the guide 7 against its opposite land. It should be noted that the spring 10 practically does not act on the link 15, so that the guides 6 and 7 can be pressed against the rods 1 with any desired force without the risk of any reaction on the spool 13.

During the rotation of the drum 2, 3, 4, the rods 1 are thus adjusted by the guides 6, 7 so that their Bind a change in thickness of the item 11 to be treated Define curve, with a curve registered once during the next rotation of the drum from the Guides 6 and 7 will be deleted and replaced by a new curve »

In order to enable reading of the rods set by guides 6 and 7, these must be temporarily be locked in their position · For this purpose the rods 1 according to the invention at her between the side parts 2 and ■ 3 lying section has a protruding thread, the same distance

The rods 1 interlocked with the upper part of the drum required delay before a reading before rich tong which is essentially formed by two lobes 29 and 30, which are arranged on both sides of the drum and on axes 33 "or .34 pivotable levers 31 and 32 are mounted. A leather 35 attached to the levers 31 and 32 seeks these levers to approach each other and the lumps 29, 30 towards the ends of the Press stick 1 »»

The levers 31 and 32 have extensions 36 and to which links 38 and 39 are hinged, which to their opposite end to .ein compensating lever 40 are articulated, which in its center at 41 to a pivoting lever 42 is hinged. This lever is pivotable about an axis 43 at one end and carries at its other end a fork 44 for controlling a belt 45 of a gearbox, which, in a manner known per se, is opposed by two arranged frustoconical pulleys

46, 47 is formed and for driving the stretching device serves.

The above gate direction works as follows: The position of the register 1 determines the position of the reading rollers 29, 30, which are constantly pressed by the spring 35 against the ends of the bars.The position of these rollers 29, 30 is determined by the cables 38, 39 40 the angular position of the lever 42 and thus the position of the Siemens 45 on the frustoconical pulleys 46,

47, i.e. the drive speed of the stretching device.

The above device has in particular the following forteile on s · .j

Due to the presence of the balance lever 40 the lever 42 occupies an intermediate position with respect to the positions of the knobs 29 and 30, which makes the operation of the ' Device softly maoht and at the same time allows her to follow sudden fluctuations in both directions, in contrast to the known devices, which are for sudden fluctuations are not suitable. Further, if the fork 44 encounters abnormal resistance, one of the lobes may 29, 30 leave the corresponding end of the rods 1, the spring 35 then acting as a force limiter.

The principle of the compensating lever can also be applied to the device for adjusting the registration rods 1 as shown in FIG. In this figure one finds the guides 6, 7, which around axes 8, 9 are pivotable and by a spring 10 against the. £ nden of Bars 1 are printed.

I) Ie actuation of the funnings 6 and 7 by the crime roll 13, which is carried by the pivot lever 14, which is under the action of a spring 48, takes place here Via a link 49, which engages a compensating lever 50, which is attached to extensions 51 and 52 the guides 6 or 7 is articulated.

The mode of operation of this device is basically the same that explained with reference to Fig. 1, i. the registration rods 1 are through the fan posts 6 and 7 accordingly The information transmitted by the Zaster 13 is set.
