  • Each guide surface 60a, 60b is part of a respective lateral shoulder or a lateral cheek of the deflection roller 38.
  • the height of the guide surfaces 60a, 60b - relative to or above the contact surface 59 of the guide roller 58 - each between 2.5 mm to 5 mm (height perpendicular to the contact surface 59). In other words, the guide surfaces between 2.5 mm to 5 mm above or beyond the contact surface.
  • the deflection rollers 40a, 40b may, by the way, also have corresponding (in particular cylindrical) contact surfaces and lateral guide surfaces for the tear strip web 16.
  • the carriage 37 is taking the Aufr effetstMailbahn 16 and the loop 39 thereof within the interior 34 in the vertical plane up and down movable, see. the double arrow in Fig. 4 ,
  • a suction or vacuum opening 41 of a negative pressure or vacuum pump having vacuum device is arranged, namely in the lower region of the interior 34th
  • the suction opening 41 By means of the suction opening 41, in each case the subspace of the interior space 34 arranged below the slide 37 can be subjected to negative pressure. During operation of the loop memory 26 (in addition to the force of gravity), this negative pressure causes an (additional) force on the slide 37 downwards or in the direction of the suction opening 41 and thus for excellent dynamics of the loop memory 26.
  • the cross-sectional contour of the interior 34 is adapted to the bottom 42 and the bottom of the carriage 37 (or another carriage section) so that between the bottom 42 of the carriage 37 and the inner surface 44 of the loop memory 26 delimiting the interior 34 only one narrow (present circumferential) gap 43 is present.
  • the inner surface 44 is part of one or more upright side or housing walls 45 of the loop memory 26, they extend between the open loop storage side 35 and the closed loop storage side 36.
  • the carriage 37 automatically moves upwards or downwards within the loop store 26.
  • the current position of the carriage 37 in the interior space 34 can be influenced by suitably setting the current (rotational) speed of the motor-driven reel 15 or optionally additionally the (rotational) speed of the reel 18 by means of a control.
  • the speed of the reel 15 of the tear strip web 16 is regulated so that the carriage 37 is located as centrally as possible within the interior 34.
  • the loop memory 26 is assigned a filling level sensor device 47.
  • This has an elongated magnetic cylinder sensor 48 which is positioned outside of the inner space 34 parallel to this or parallel to the direction of movement of the carriage 37.
  • the magnetic cylinder sensor 48 interacts with a (permanent) magnet 49 arranged on the carriage 37 and can detect the current position of the permanent magnet 49 or corresponding to the carriage 37 and report it to the controller.
  • FIG. 7 An alternative to the aforementioned position determination is in Fig. 7 shown.
  • a passage opening 50 connecting the interior space 34 to the environment is arranged, which is closed by a transparent plate 51, for example a glass plate.
  • a laser triangulation sensor device 52 is positioned below the opening 50, outside the interior space 34. This emits laser beams 53, each ending at the bottom 42 of the carriage 37, are reflected back and based on known measuring methods, with which such devices work, the current Distance of the bottom 42 of the sensor device 52 and thus determine the position of the carriage 37 in the interior 34.
  • the controller automatically sets the web tension of the tear strip web 16 to a predetermined value by changing the negative pressure in the loop memory 26, in particular after measuring the actual value of the web tension and depending on this actual value.
  • the stop 46 in the present case is a (substantially cylindrical) pin. It is understood that the stop can also be formed in a different form.
  • the handling device 10 also has a magnetic gripper 54 which comprises a holding magnet, namely in the upper region of the loop store 26 above the open side 35.
  • the carriage 37 can then be temporarily fixed to the magnetic gripper 54, cf. Fig. 5 ,
  • the carriage 37 may then have a component interacting with the holding magnet, for example a magnet of opposite polarity.
  • a component interacting with the holding magnet for example a magnet of opposite polarity.
