  • a dancer unit 15 is also provided on the movement path Mxz from the bobbin 1 to the feed unit 16, which can optionally be configured as part of the deflection unit 13.
  • the dancer unit 15 comprises dancing deflection rollers 14b, which can ensure a predefinable tensile force in the belt 2 against the gravitational force depending on their own weight and, if necessary, provided compensating masses.
  • the belt 2 can be deflected by a deflection angle ⁇ , which can be predefined in particular via the relative arrangement of the rollers 14.
  • the module 10 is preferably mounted on wheels 17 and can be displaced and positioned independently of the system 20, in particular in freely selectable standing positions on a floor of a machine hall.
  • the module 10 provides two functions on the movement path Mxz from the reel 1 to the feed unit 16, optionally separately from one another, but optionally also in combination with one another.
  • a width compensation device 18 comprises, in particular, deflection roller webs 14.1 arranged one after the other in a cascade-like manner with a decreasing width y14.1, and a length compensation device 19 enables length and tensile force compensation, in particular also at least partially by means of the dancer unit 15.
  • the system 20 can in particular be designed for cutting, gluing, folding cardboard boxes or similar packaging materials.
  • the system 20 can be designed as a fully automatable process system.
  • a pulling unit 23 for pulling the strip-shaped material 2 can be coupled to the module 10 at the coupling point Pxyz, so that the material 2 can be unwound from the spool 1 by exerting a pulling force and drawn into the system 20, for example into a bunker 21.
  • the Bunker supplies an additional material buffer on the system side, for example even if the system is temporarily shut down for a few seconds or minutes.
  • the z coordinate of the coupling point Pxyz can be optimized individually for a respective system 20 via the height z16 of the feed unit 16, in particular via the length of the carrier 12.1.
  • the system 20 can provide several deflection rollers or deflection points 24 for guiding the belt 2, in particular for defining a movement path up to a point of contact with cardboard boxes (gluing or gluing process).
  • a plane of movement Exz of the belt-shaped material 2 corresponds at least approximately to the direction of the tensile force.
  • the coordinates x, y, z denote the depth, width and height directions.
  • the present invention makes it possible in a simple manner to change the path of movement of the material 2 from a comparatively large width y1 of the coil 1 (winding width), in particular a very large coil width in relation to the width y2 of the strip-shaped material 2, via deflection rollers 14 with different (in particular cascading decreasing ) To gradually converge or limit widths y14, y14.1 to a width range that is advantageous for the handling of the material 2 and for the transfer of the material 2 to the system 10.
  • the module 10 is passive with respect to the unwinding process.
  • the coil 1 does not have to be driven.
  • a drive 11. 2 provided on the axle 11 can also act on the reel 1, in particular for the purpose of minimizing the tensile forces acting on the strip 2.
  • a comparatively large material buffer can still be provided in a gentle way.
  • the drive 11.2 can be controlled via a control device 30, in particular as a function of tensile force values or position data from sensors which are coupled to the belt 2. This enables, for example, the unwinding process of the reel to be started in response to a tensile force F1 exerted by a system 20 on the strip 2 or the module 10.
  • Fig. 1 illustrates the routing of the material 2 from the spool 1 to the transfer point on the feed unit 16.
  • This buffer area can be designed individually, in particular with regard to the size or mass of the coil, the tensile strength of the material 2 and the tensile force F1 exerted by the system 20.
  • the dancer unit 15 comprises, for example, two upper stationary deflecting rollers 14a and three lower dancing deflecting rollers 14b.
  • the dancer unit 15 comprises, for example, two upper stationary deflecting rollers 14a and three lower dancing deflecting rollers 14b.
  • the tape 2 is guided around nine or ten deflecting rollers 14 in this exemplary embodiment. This also increases the distance available for compensation, for example by a factor of 3 to 5, depending on the arrangement of the dancer unit.
  • the dancer unit 15 preferably comprises a guide 15.1 for the movable deflection rollers 14b, in particular a linear guide, as well as at least one position sensor 15.2 provided on the guide, in particular measuring linearly inductively. Position data of the Dancer unit 15 are determined and transmitted to a / the control unit 30 (in particular wirelessly), so that the control unit 30 can control and regulate, for example, a drive 11.2 for positioning or rotating the coil 1 depending on a deflection (change in position) in the dancer unit. This provides further optimization potential, particularly in the case of particularly large, heavy bobbins 1.
  • Fig. 2 also illustrates a height range ⁇ z for latitude and / or longitude compensation.
  • the height area .DELTA.z is enclosed by the housing 12, and the pulleys are all arranged in the height area.
  • the height of the height range ⁇ z is approximately a factor of 1.5 to 2 of the diameter of the coil 1.
  • the guide 15.1 of the dancer unit 15 can optionally extend at least approximately over the entire height range ⁇ z. Last but not least, this also provides a large buffer with a comparatively compact installation space.
  • the coil axis 11 is mounted on one side.
  • the reel shaft 11 can optionally be supported at both ends (no free end 11.1).
  • Fig. 3 the width ratio of the coil width y1 to the material width y2 is illustrated.
  • Fig. 4 the web width y14.1 is illustrated.
  • the coil width y1 is approximately a factor of 3 of the web width y14.1
  • the web 14.1 of the first deflection roller is arranged at least approximately centrally relative to the coil width y1.
  • the material 2 is comparatively narrow, but cannot be twisted or twisted, but rather has to be handled in its own extension plane due to the web-like configuration (compare arrangement in bunker 21 in FIGS Fig. 6, 7 ).
  • Fig. 5 , 6 and 7 Systems shown relate, for example, to the automated processing of packaging material, in particular cardboard boxes. The process can in particular include folding, cutting, gluing or the like.
  • Fig. 5 an exemplary arrangement of a module 10 coupled to a system 20 is shown.
  • Fig. 6 a bunker 21 of a plant 20 according to a further application is shown in detail.
  • Fig. 7 shows this arrangement from the opposite perspective.
  • Sensors in particular force sensors, can be provided in the individual deflection rollers or also at other positions. Depending on the configuration of the process, position sensors can be arranged along the movement path of the strip-shaped material or on the moving components.
