  • the covering or the paper in strips is inserted one or more times between a system of electrodes arranged in pairs passed through.
  • the electrodes can, for example, be provided in rows on swiveling holders, as shown for example in AT-PS 364 637 or according to DE-AS 1 213 327, on rotating rollers.
  • a plurality of carrier pairs or pairs of rollers can be arranged one behind the other, so that the rows of holes which have been produced by the electrodes of the first pair of carriers or rollers are subjected to the perforation by spark breakdown several times, as a result of which the small ones present are particularly affected Widen holes, while the larger holes do not experience any significant change.
  • the object of the present invention is to create measures by which a very high degree of regularity of the holes is achieved, regardless the fact that irregularities can occur on the one hand in the production of the base paper and during printing, and on the other hand an uneven erosion of the electrodes can lead to unpleasant fluctuations in the air passage values.
  • At least two chamber parts are provided, between which the perforated strip can be guided, one chamber part having a transmitter and the other chamber part having first and second receivers for receiving the waves emitted by the transmitter, the chambers in the region of the strip Own slots.
  • a lens for bundling or focusing the waves onto the receivers is provided in the chamber part, which contains the receivers, following the slot that allows the waves to pass through.
  • an aperture is provided in the chamber part, which contains the transmitter, between the slot that transmits the waves and the transmitter.
  • a deflection mirror is provided in the chamber part, which contains the transmitter, between the slot that allows the shafts to pass through and the diaphragm.
  • an intermediate wall for the optical separation of the beam paths for the first and second receivers is provided in the chamber part which contains the receiver.
  • an intermediate wall for the optical separation of the beam paths for the first and second receivers is provided in the chamber part which contains the transmitter.
  • the strip 1 to be perforated is drawn off a decoiler 2 and guided over a deflection roller 3 between a first set of mutually opposing rows of electrodes 4 which are carried by electrode holders 5 which, for example, as in AT-PS 364 637, can be designed so that they can be set at a certain angle to the direction of movement of the strip 1, as a result of which the mutually opposite electrode rows 4 also assume a corresponding angle to the direction of movement of the strip 1, which is the distance between those formed by the opposite electrodes Rows of perforations determined.
  • three groups of carrier pairs 5, 5a, 5h are provided, with two deflecting rollers 6, 6a and 7, 7a deflecting the strip 1 from one electrode system to the other electrode system, so that the strip in the present case moves the first electrode system from below above, the second electrode system from top to bottom and the third electrode system again from bottom to top happens.
  • the setting angle of all three carrier pairs 5, 5a, 5b is the same here, so that the sparks of the second and third systems pass through the same holes which were produced by the first system.
  • the strip 1 After the strip 1 has passed the last electrode system, it is guided through the measuring device via deflection rollers 8, 8a, 8b.
  • FIG. 5 four fields 9 of rows of perforations can be produced for each strip, for which purpose a carrier pair 5 or 5a or 5b (FIG. 1) is provided for each field in each system, all carrier pairs having the same angle setting.
  • a strip 1 if it is to serve as a mouthpiece covering, is wound over adjacent ends of two coaxially lying cigarettes, whereupon the two cigarettes are cut along the center of the covering strip, as indicated by dash-dotted lines in FIG. 5, so that each mouthpiece has two fields of rows of perforations owns.
  • a separate measuring device is provided for each field of rows of perforations.
  • Figure 1 only one measuring device is shown schematically, while the other three measuring devices are indicated by successive dash-dotted lines. After passing the measuring devices, the strip is wound onto a reel 12 by a deflection roller 8c and rollers 10, 11.
  • the measuring device can have only one measuring chamber 13, which consists of two chamber parts 14, 15, between which the strip 1 is lower is led right to the image plane.
  • a punctiform light source 16 is provided, the rays of which pass through an aperture 17 and a slot 18 in an end wall 19, the row of holes 9, and enter the chamber part 14 through a slot 20 in the end wall 21, and through one in the connection through the slot 20 provided lens 22 which directs the rays passing through the perforated holes of the field 9 by direct focusing of the light source 16 onto a photocell 24, while the rays passing through the imperforate part of the field 9 reach a photocell 23 as scattered light.
  • the signals from the two photocells 23, 24 are fed via a preamplifier 25 to a signal amplifier (not shown), which will be described later. From the signal amplifier, the measurement signal reaches an actual value display 26 on the one hand and a control device 28 on the other hand.
  • a setpoint generator 27 is also connected to the control device 28. If the actual value deviates from the set value, the control device 28 outputs a control signal to the respective power control devices 28a, 28b, 28c, so that the spark energy is set to the respectively optimal value.
  • each chamber part 14 or 15 can be connected to a blown air line 29 or 30, as a result of which air flow through the chamber parts 14 and 15 in the direction of the slots 20 and 18, respectively is, so that penetration of dust from the holes of the rows of holes of the strip 1 into the chamber parts 14 and 15 is prevented.
  • each of the two chamber parts 14 and 15 is divided into two chambers 14a, 14b and 15a, 15b.
  • the light source 16 is accommodated in a housing 31, from which the light rays impinge through deflectors 32 and 33 on deflecting mirrors 34 and 35, one of which is accommodated in each of the chambers 15a and 15b.
  • the two chambers 15a and 15b have a common end wall 19 'in which a slot 18a and 18b is provided for each of the two chambers.
  • the chambers 14a, 14b have a common end wall 21 which is provided with corresponding slots 20a, 20b, behind which a lens 22a, 22b is arranged.
  • the slots 18b, 20b are located in a perforated zone and the slots 18a, 20a in a non-perforated zone of the strip 1, so that the rays reflected by the deflecting mirror 34 against the slot 18a from a photocell 23 of the chamber 14a and those from the deflecting mirror 35 against rays reflected from the slot 18b are captured by a photocell 24 of the chamber 14b.
  • the measurement is carried out in the same way as in the case of the device according to FIG the mirror provided.
  • Figure 6 shows an embodiment of a measuring amplifier according to the invention.
  • the signals emitted by the photocells 23, 24 are each passed to first and second preamplifiers 41, 42, which are designed as operational amplifiers and are provided with corresponding supply voltages and with a corresponding RC network (not designated) between the input and output to get the desired gain and frequency response.
  • the outputs of the preamplifiers 41, 42 are connected via coupling resistors (not designated) to the inputs of a differential amplifier 43, which is negatively coupled in a conventional manner.
  • a likewise negative-coupled operational amplifier 45 for setting the zero point of the measuring direction is connected via a coupling resistor (not designated).
  • the operational amplifier 45 is supplied with a DC voltage signal via a variable voltage divider 44, which is additively superimposed on the signal of the differential amplifier 43 at the input of the operational amplifier 45.
  • the output signal of the operational amplifier is on the one hand an operational amplifier 46 connected as an output stage and on the other hand via a series resistor network 47 and a switch 48 passed to a zero balance display instrument 49. In the position of the switch 48 shown, the rough adjustment of the zero point takes place, while in the other the fine adjustment takes place.
  • the output of the operational amplifier 46 is connected to the actual value input of the control device 28, which is preferably designed as a PID controller.
  • the zero adjustment takes place in such a way that initially only perforated paper is introduced into the measuring chamber 13, so that essentially a signal of the same size is emitted from the two photocells 23, 24 to the preamplifier and signal amplifier 25 or 40. Subsequently, the zero point is set precisely by means of the variable voltage divider 44 via the rough and fine adjustment, after which the perforation process can be initiated.
  • the diodes (not designated) in the series resistor network 47 serve as overload protection for the display instrument 49.
