  • a rotary drive of the drive gear 49 about the axis of rotation 52 through the storage carriage displacement drive 48 leads to a circumferential displacement of the drive chain 51, which in turn causes a displacement of the storage carriage 42 along the storage carriage guide 43.
  • the storage carriage 42 is displaced either in the direction of the second end region of the storage carriage guide 43 or away therefrom along the storage carriage guide 43.
  • the storage trolley displacement drive 48 is assigned a position sensor 53 for detecting the respective position of the storage trolley 42 along the storage trolley guide 43.

  • the control device 60 is connected via a fifth signal line 65 to the first electro-pneumatic actuator 55 in signal connection and is able to control the first electro-pneumatic actuator 55 to operate the first brake unit 54 in accordance with the fifth signal line 65.
  • the control device 60 is connected via a sixth signal line 66 to the second electro-pneumatic actuator 58 in signal connection and is able to control in use on the sixth signal line 66, the second electro-pneumatic actuator 58 for actuating the second brake unit 57 accordingly.
  • the signal lines 61 to 66 are alternatively formed by wireless signal connections.
  • the first unwinding device 4 is currently active.
  • the finite first material web 2 is unrolled from the first material roll 3 and conveyed. It is guided via the first feed roller 17, where the finite first material web 2 is deflected by about 90 °, to the cutting and connecting arrangement 18.
  • the finite first material web 2 is passed between the second adhesive roller 29 and the first pressure roller 33.
  • the finite first material web 2 between the spaced-apart pressure rollers 33, 35 passed through and is partially adjacent to this circumferentially.
  • the finite first material web 2 or the endless material web 1 becomes the material web tension-influencing roller 37 out and deflected there by about 180 °.
  • the endless web 1 is then guided to the first guide roller 41, where it is deflected again by about 180 °.
  • the endless material web 1 is guided around the second deflection roller 45, where it is deflected again by approximately 180 °.
  • the endless material web 1 is guided around the third guide roller 46, where it is again deflected by about 180 ° and is guided to the material web outlet 44. In the material web outlet 44, the endless material web 1 leaves the splice arrangement.
  • the first preparation device 22 is located adjacent to the first feed roller 17 or at the first end region of the guide 27.
  • the finite second material web 5 is held by the cutting and connecting arrangement 18 or the second adhesive roll 29 in a waiting position, so that it can be connected to the endless material web 1 as needed with the finite first material web 2. This takes place in particular when the finite first material web 2 comes to an end.
  • the second unwinding device 7 is thus inactive.
  • the finite second material web 5 is not being unrolled or conveyed by the second material roll 6.
  • the first brake unit 54 applies a first braking force to the first material roll 3.
  • the control device 60 controls the first electro-pneumatic actuator 55 accordingly.
  • the first braking force is selected such that the web tension prevailing in the first unwinding device 4 of the unrolling first material web 2 is greater than a desired web tension of the endless material web 1 on the storage trolley 42.
  • the storage cart 42 is normally in its zero position, which is also shown in the figure. However, during operation of the splicing arrangement or the corrugated cardboard plant, the web tension of the endless material web 1 may change, which leads to an automatic or independent displacement of the storage wagon 42 along the storage carriage guide 43 and thus also to an automatic or independent change the amount of memory of the endless web 1 in the Spliceanssen leads.
  • the storage carriage 42 is thereby automatically or independently pulled towards the second end region of the storage carriage guide 43, whereby the amount of storage of the endless web 1 in the splicing arrangement is reduced.
  • the first brake force is reduced by the first brake unit 54, which is achievable by corresponding actuation of the first electro-pneumatic actuator 55.
  • the storage wagon 42 thus returns to its zero position.
  • the storage carriage 42 When, for example, the web tension of the endless material web 1 on the storage carriage 42 is reduced, the storage carriage 42 is thereby automatically moved away from the second end region of the storage carriage guide 43, whereby the amount of storage of the endless material web 1 in the splicing arrangement is increased.
  • a displacement of the storage carriage 42 away from the second end region of the storage carriage guide 43 also leads to a reduction of the web tension of the endless material web 1 in the splice arrangement.
  • the web tension of the endless material web 1 drops below the external web tension of the endless material web 1, as a result the storage wagon 42 automatically returns to its zero position automatically or independently.
  • the first braking force is increased by the first brake unit 54, which is achievable by corresponding operation of the first electro-pneumatic actuator 55.
  • the storage wagon 42 thus returns to its zero position.
  • the first braking force is favorably chosen so that the web tension of the finite first material web 2 in the first unwinding device 4 is greater than the web tension of the finite first material web 2 or the endless web of material 1 desired on the storage trolley 42.
  • the web tension of the endless material web 1 in the splice arrangement can also be influenced by the material web tension influencing roller 37, which ultimately leads to a corresponding displacement of the storage cart 42 along the storage carriage guide 43, as stated above leads.
  • the storage cart 42 is stable in its zero position.
  • the respective position of the storage carriage 42 is dependent on the drive of the material web tension-influencing roller 37 which acts to guide the storage carriage 42 in its zero position driving or braking on the endless material web 1 to change the web tension of the endless web 1 in the Spliceanssen.
  • the position control of the storage carriage 42 is so independent of the storage carriage displacement device 47 can be changed.
  • the speed of the material web tension-influencing roller 37 is calculated as a function of the storage quantity of the endless material web 1 in the splicing arrangement.
  • the desired web tension of the endless material web 1 on the storage carriage 42 is advantageously generated exclusively by the web tension-influencing roller 37.
  • the material web tension-influencing roller 37 is driven so that it compensates for a difference between the web tension of the rolling finite first material web 2 that prevails on the first unwinding device 4 and a desired web tension of the endless material web 1 on the storage carriage 42.
  • the storage carriage displacement drive 48 is conveniently applied with a desired torque.
  • the torque of the storage carriage displacement drive 48 corresponds in particular to a setpoint specification by the control device 60.
  • the speed specification of the storage carriage displacement drive 48 is advantageously greater than the sum of all delays that occur during operation of the splicing arrangement.
  • the differential force of 200 N is supplied by the web tension control roller 37.
  • the web tension-influencing roller 37 is braked, so to speak.
