  • the motor 129 of the drive 86 drives its worm 130 to the worm wheel 131, this the spindle nut 132 and this in turn the spindle or the rod 87.
  • the piston 83 moves in the Drawing to the right, at least in the direction of the heater 90, and pushes the adhesive pieces P to the heater 90 out.
  • the spindle or the rod 87 is secured with respect to the adjusting shaft 84 against rotation.
  • the piston 83 is secured against rotation in the staging area 28.
  • a position sensor 135, such as a micro-switch, serves to detect the position of the spindle nut 132 and thus indirectly to detect the position of the conveying member 82. Namely, when the piston 83 abuts with a predetermined pressure on the adhesive pieces P in the staging space 28, the spindle nut 132 the rod 87 / spindle no longer driving in the direction of an adjustment in the direction of the heater 90, but rotates on the spindle or rod 87 in a sense away from the heater 90, wherein it exerts an increasing force on the spring 133, which finally an example operated as a lever transmission member 136 is actuated, in turn, the position sensor 135 triggers. Then, a predetermined pressure on the adhesive pieces P is reached. Now there is a possibility that the drive 86 simply shuts off.
  • the motor 129 driving the worm 130 still runs somewhat in the sense of relaxing the pressure on the adhesive pieces P.
  • the position sensor 135 thus triggers a reversal of the motion of the drive 86.
  • the motor then still runs back a predetermined distance, so that the arrangement is relaxed so far that the adhesive can expand when switching on the heater 90 by a certain amount and thereby no excessive pressure on the closing valve, at least in the direction of the adhesive outlet 71 exerts, but a defined, depending on the temperature of the heater 90 pressure.
  • the functions of the gluing machine 10 are controlled by a control device 160, preferably a microprocessor control, controlled.
  • the control device 160 includes, for example, a processor 161 and a memory 162 in which one or more control programs 163 are stored.
  • the controller 160 receives a signal from the tape feed switch 17 and accordingly drives the drive motor 53.
  • controller 160 may also drive, for example, the actuator 141 to fully open and close the adhesive outlet 71, or may also drive the adhesive outlet 71 partially in proportion to the desired adhesive application thickness.
  • control device 160 also controls the motor 129 of the pressure-generating unit 81 or of the conveyor 89.
  • the control device 160 can also be controlled by the operating interface 150, for example by means of the operating keys 154 and, in turn, in turn directs the display 151 to suitable displays.
  • the control device 160 now ensures that only so much adhesive K is prepared that no or only insignificantly drops adhesive K from the adhesive outlet 71.
  • the control device 160 is, for example, a component of the preparation arrangement 80 for providing a volume of the adhesive K at the adhesive outlet 71.
  • the control device 160 controls the components of the preparation arrangement 80 involved in this manner in dependence on at least one adjustable and / or sensor-detectable parameter in such a way, that they are the volume of the adhesive K for the Provide application to the adhesive outlet 71 in a suitable for application to the Umleimerband U liquid state in the exact size possible.
  • the parameters are, for example, at least one parameter sensed by sensors, for which purpose suitable sensors are provided, or parameters which can be set, for example, on the operating interface 150, for example a layer thickness of the adhesive K which is to be applied to the band U.
  • the adjustable parameters can also be detected by the control device 160, so to speak, by recognizing its respective position as a parameter when controlling, for example, the motor 129 and / or the drive motor 53 and / or the servomotor 141.
  • the so-called volumetric control of the control device 160 only opens the closing valve realized by the valve member 74 when adhesive K is actually to be applied to the banding band U.
  • the amount adjustment is so sensitive and accurate that not too much and not too little adhesive K is applied.
  • controller 160 evaluates, for example, the closing parameter 144 and / or the adhesive thickness value 143.
  • controller 160 is also configured to evaluate the width value 149.
  • the width value 149 could also be known to the control device 160, for example, in that it actuates a positioning motor (not shown), for example a stepping motor, for adjusting the width setting device 60 and thereby knows its position correlating with the width B.
  • a positioning motor not shown
  • a stepping motor for adjusting the width setting device 60
  • the control device 160 controls the conveyor 89 and / or Their motor 29 so that always the drip-free exactly matching amount of volume of the adhesive K for coating the Umleimerbands U exits from the outlet openings 73.
  • control device 160 by the exact startup procedure described above after the insertion of adhesive pieces P in the staging space 28 and the exact position of the motor 129, which ultimately represents a quantity parameter 164 for the existing adhesive supply.
  • a sensory detection with, for example, an optical sensor or a weight sensor or the like of the adhesive supply in the staging area 28 would also be possible.
  • the motor 129 so to speak contributes its position signal to a calculation of a range information.
  • the control device 160 is able to calculate in advance from the still existing adhesive stock in the staging area 28 which length of Umleimerband U can still be coated with adhesive K.
  • the range information is output by the control device 160 at the operating interface 150 as range display 152.
