    An apparatus for monitoring the production of elongate profiles which are formed from one or more mixtures of rubber or thermoplastics material in an extrusion head which is fed by one or more extrusion devices. The profile passes through a cooling zone in which longitudinal shrinkage of the profile occurs. The actual shrinkage is monitored and compared with desired shrinkage by a control device which controls the drive means for the extrusion devices. The profile also passes over a weighing device which determines the weight per unit length thereof, with the weighing device also being operatively connected to the regulating or control means. If a deviation from the desired shrinkage in the zone or station is ascertained, the regulating device sets a new, corrected, desired weight per unit length value to be achieved at the weighing device. To achieve this desired weight per unit length, the drives for the extrusion devices are each adjusted by a uniform amount by the regulating or control device. By achieving the desired weight value, the desired amount of shrinkage in the cooling path or station is achieved.

    an extruded profile tape and subsequent cooling of the extruded profile tape by feeding it to a cooling section bounded by several conveyor belts. In the cooling section, the linear shrinkage value of the extruded profile tape is read. The read values are transmitted to a regulator connected to the scales for measuring the weight. linear meter, and when deviations from the set value of linear shrinkage are set using the scale controller to measure the weight of the linear meter, the corrected value of the set weight of the meter.

Measuring devices 10-12 are connected to controller 13. Devices 14-16 are connected to said controller 13 to control the speed of rotation of the screws (not shown) to affect their respective speed of rotation. The apparatus contains a scale 17 for measuring weight.
    5 running meters of extruded profile tape. The scales 17 are connected on one side with the outlet 3 of the head 1, and on the other side with a device 18 for cooling the extruded fillet tape. The device 18 is made in the form of several conveyor belts 19 arranged one above the other. The installation additionally contains a regulator 20, a micro processor 5 (not shown) for controlling the regulator 20, a scale 21 for measuring the weight of a single meter of extruded profile tape, gauges 22 of the rotary loop width cooled eksch

The regulator 13 is connected to the balance 17 to record the weight of three different tape mixtures. The scale 17 is connected to the outlet 3 of the head 1. The regulator 13 is connected to devices 14-16 for controlling the speed of rotation of the screws of the extruders 7-9, respectively.

    1. The profile tape 31 for treads then passes through a scale 17 to measure the weight of a meter. Deviations from the specified weight per running meter of the tape 31 are set by the regulator 13. Too low weight per running meter indicates that too little mixture is extruded from one or several working nozzles 4-6. Deviations from the setpoint of extruders 7–9 with respect to pressure and temperature are recorded by measuring devices 10–12, respectively, and transmitted to controller 13. If regulator 13 Receives, for example, a value of a too low weight per meter (determined by means of scale 17) then the regulator 13 checks the setpoints of pressure and temperature in the working nozzles 4-6, If then the regulator 13, for example, determines that the pressure and temperature are in the working nozzle. 4 has been reduced, this is a sign that the extruder 7 is delivering some / less of the mixture than specified, so that the belt 31, consisting of all three mixtures, will be easier. As a result, the temperature must also be recorded, since, for example, when the temperature rises, the viscosity of the mixture material decreases, i.e. the material of the mixture will be more fluid, as a result of which its measured pressure decreases without reducing its supply volume. Thus, the scale 17 will not fix any changes. But, if the read pressure decreases without increasing the temperature, then this is an absolute sign that the amount of material of the mixture fed through the screw of the extruder 7 has decreased. If the readings of both pressure and temperature decrease to a predetermined degree and these values are fixed by the controller 13, then the device 14 is controlled to control the speed of rotation of the screw of the extruder 7. The weight of a meter of tape 31 is reduced by that fraction of the mixture material which was not fed through the extruder 7. Based on the set weight of the running meter of the belt 31 on one side, and on the basis of the pressure and temperature that are too low, measured by measuring device Yu installed on the ra

    By using the nozzle 4 of the extruder 7, the regulator 13 accordingly increases the rotational speed of the screw of the extruder 7 (for example, 1.5 turns), so that the extruder 7 will again have a slightly increased output until the specified weight per meter of belt 31 is restored After weighing 17 to measure the weight of a meter, the tape 31 gets to the shrinkage section 27. In this area, about 8% of the total shrinkage of the tape 31, equal to about 9.5%, is constantly carried out.
    The starting change of the angle of inclination of the roller portions 28 and 29 can be influenced by the degree of shrinkage of the belt 31 so that with a greater angle of inclination a more significant shrinkage occurs (for example, 7% of the unit of length), and with a gently sloping arrangement of the roller portion 28 or 29 less.
    After that, the tape 31 for the protectors falls on the second shrinkage impacting only the stretch section 27 to measure the weight of the meter, connected to the controller 20. In accordance with deviations from the specified weight of the meter, the regulator 20 adjusts the angle of the roller sections 28 and 29 stretch 27 shrinkage.
    The shrinking section 27, the scale 21 for measuring the weight per unit weight and the regulator 20 form a unit acting independently of the other units.
    In the course of further advancement, the tape 31 enters the cooling device 18, consisting, for example, of three arranged one above the other.
    conveyor belts 19. I
    In the process of cooling tape 31
    it is also subjected to shrinkage determined by experimental data, equal, for example, to 1.5% of a unit length. Conveyor belts 19 are driven at constant speeds, precisely measuring 1.5% shrinkage and excluding pulling caused by the conveyor belts 19.
    To determine the actual amount of shrinkage of the belt 31 on the cooling device 18, on one side of the conveyor belts 19, for example, light strips 24 are installed, creating a light process, or panes 26 connected to potentiometer 25 are installed so as to control the hanging loop of the belt 31 when turning on the lower located conveyor belt 19 and thereby shrinking, i.e. length
    FIG. 2 partially shows the device: a device 18 for cooling, on which ipoM, respectively, on the sides of the rotation, are models of 26 connected with potentiometer 25. f With a constant set speed of the conveyor belt of 19 m If shrinkage occurs, i.e. decline
    The photocells vary. An electronic data processing unit (not shown) is used to determine the movement of the tape 31 and thereby shrink it.
    Formula of the invention
    1. A method for controlling the manufacturing process of elongated profiles consisting of one or several mixtures, of rubber or a thermoplastic synthetic material, comprising
    the length of the tape 31 is greater than that set; extrusion of the profile tape with
    1.5%, to which the speed of the conveyor belts 19 is set, the pilot 26 moves to the lower position | a.i and the potentiometer 25 transmits this change to the scale 17 for measuring 20 weights of the meter 31 of the tape 31.
    Based on this, wems 17 for measuring the weight per weight indicate to the regulator 13 that the entire belt is overweight. 31.25
    The controller 13 is programmed so that in this case all indicators of the rotational speed of the extruders 7–9 are evenly adjusted in the direction of help using one or multiple extruders of the extrusion head, measurement of the linear measure of extruded profile tapes and subsequent cooling of the extruded profile tape by its feeds to the cooling zone limited by several transport strips, characterized in that, in order to increase the quality of the profiles to be measured, the value of linear shrinkage is considered kstrudirovannoy straight philous Ribbon plot cooling few values transmitted to regu
    nor about 0.5 turnover, so that the torus connected to the scales for 35
    the output is accordingly uniformly increased, as a result of which the overall shrinkage is also reduced accordingly, i.e. the tape 31 is somewhat stretched.
    Since the shrinking portion 27 is set at a constant 8% shrinkage, the shrinkage on the cooling device 18 is manifested so that the belt 31 lengthens, for example, by 0.5%. Thus, the trough 26 returns to the mid-position, and the tape 31 shrinks according to the once determined values, at which the speed of the conveyor belts 19 is set.
    Shrinkage values on cooling device 18 can be recorded and set also by light strips 24, as shown in FIG. four,
    The principle of operation of the light strips 24 may be as follows.
    From the source 23 of the light emitted from the light rays. At receiver 30, they are perceived as discrete photocells. If the tape 31 is between the source 23 of the light and the receiver 30, then the beams 6 cannot get onto 55 subordinate photocells.
