Claims (1)

J 8880 VII / 55 e The invention relates to a liquid Measuring and metering device for devices for dampening running webs auisi paper or the like. , '■ ^: In contrast to the known devices of this type,! the liquid measuring and metering device according to the invention 'is characterized by the simplicity of the construction and by its safe operation. The arrangement is soi made that an overflow container, which is ίο aiuicihi operate the known devices of this type, is connected via a pressure line to a pressure vessel which dispenses the liquid and displays the amount of liquid dispensed per unit of time, whereby to achieve a large control range ¹ 'both the cross section of the pressure line and; the outlet opening of the pressure vessel are variable .. The pressure vessel is also assigned a pressure column, preferably made of glass, which, in conjunction with a calibrated scale, indicates the amount of liquid dispensed per unit of time. As a result, the amount of liquid to be dispensed can be ^{regulated in broad 1} limiters and the amount of liquid dispensed per unit of time can easily be determined. In the drawing, an Auisfühirungsbeispiel ■ is shown and described below. ■ The material web 1 to be moistened is in a known manner via guide rollers 2 on a Bürstenifeucihtwerk moved past, the au® one circumferential brush 3, a scoop roller 4 and a liquid container 5 is formed, the for the equality of the liquid level Overflow valve 6 is assigned. The liquid is supplied to the container through the supply line 7, by the FMtesigkeits-Mess- und . Dosing device is fed. The liquid measuring and metering device consists of a container 9 provided with an overflow 8, to which the liquid is fed through the inlet 10 in an amount that exceeds the amount of liquid ^{to be dosed or 1 to be measured.} The container 9 is connected via a pressure line ¹ 11 with a pressure vessel 12, the lower end comprising: a controllable or changeable .. outlet nozzle 13 is provided. The upper · Enide of Druckbdhlälters ¹ 12 includes an od of transparent material such as glass or the like, pressure measurement made column 14 at, by means of:.. Which per unit of time delivered in conjunction with a replaceable, in accordance with the j eweilligen operating conditions calibrated measurement scale 15 amount of liquid can be read. To determine the in the, pressure vessel 12 and the prevailing Druckverhältniisse thereof aL · - nängigeni dler amount of liquid dispensed is next dler variability of the outlet nozzle 13 is a cross-section of the pressure line 11-influencing member in the form of a slide ^1! or a ¹ lock 16 is provided. With this arrangement; a relatively large control range is given, which can be determined by the selected size of the ¹ outlet nozzle 13 and a measuring scale 15 adapted to the respective conditions.
