    [31] [0031] A cutting wire 3 is arranged between the frame portions 2a, 2b, and thusextends there between, and is further connected to the respective frame portions2a, 2b. According to one embodiment, the cutting wire 3 may be arranged as asingle wire 3, i.e. extending a plurality of times between the frame portions 2a, 2bin a back and forth manner. According to one embodiment, the cutting wire 3extends between the frame portions 2a, 2b in recurrent pattern. According to oneembodiment, a plurality of cutting wires 3 extends between the frame portions 2a,2b, respectively, between the frame portions 2a, 2b may be used as well.According to one embodiment, the cutting wire 3 extends in a straight line betweenthe frame portions 2a, 2b. According to one embodiment, the cutting wire 3 is anelectric heating wire. According to one embodiment, the cutting wire 3 is a rotatingwire arranged to rotate around its own axis to provide an improved cutting ability,which is useful or even necessary to cut through certain material, e.g. EPS.According to one embodiment, the cutting wire 3 is arranged to be translated in inits axial direction for an enhanced cutting ability.

    [32] [0032] Fig. 2a shows a cutting device 1 according to Fig. 1 in a first position inrelation to an exemplary resulting cut-out and formed piece of a material 4 fromthe pivoting of the cutting device 1. According to one embodiment the material 4has a cut-out portion 4a through which the pivot axis p may extend. The cut-outportion may have the shape as a circular segment. A coordinate system isprovided comprising axis X, y, z defined in relation to the cutting device 1 of Fig. 1.Fig. 2b shows the cutting device 1 and material 4 of Fig. 2a in a y-direction. ln Fig.2b the cutting wire 3 is arranged between the frame portions 2a, 2b and extendsthere between with an angle oi to a direction perpendicular to the pivot axis p of theframe structure 2, i.e. at least in one embodiment being in relation to thehorizontally arranged connecting portion 2c. According to one embodiment, theangle d is in the range of 0,1 fourth connection points of frame portion 2b may be arbitrary. According to one 68207 embodiment, the fourth connection point has a distance from the first connectionpoint in a z-direction which is 6 mm. According to one embodiment, the cuttingwire 3 is controllable by a control device. This comprises either or both controllingthe rotations speed as well as the pattern series of the cutting wire 3 between theframe portions 2a, 2b. According to one embodiment, the location of theconnection points of the cutting wire in the frame portions 2a, 2b are controllableby a control device, thereby controlling the pattern of the cutting wire 3. As is notedthe recurring set comprises a 3a and 3b portion of the cutting wire. Fig. 2c showsthe cutting device in a negative z-direction.
    [33] [0033] Fig. 3a-Fig. 3c shows a cutting device according to Fig. 1, in a secondposition in relation to an exemplary resulting formed/cut material 4. The frameportion 2 has pivoted ca 30° from the starting position of Fig. 2a-2c. Fig. 3b showsthe cutting device 1 and material 4 of Fig. 3a in a y-direction. Fig. 3c shows thecutting device 1 and material 4 of Fig. 3a in negative z-direction.
    [34] [0034] Fig. 4a-4c shows a cutting device according to Fig. 1, in a secondposition in relation to an exemplary resulting formed/cut material 4. The frameportion 2 has pivoted ca 60° from the starting position of Fig. 3a-3c. Fig. 4b showsthe cutting device 1 and material 4 of Fig. 4a in a y-direction. Fig. 4c shows the cutting device 1 and material 4 of Fig. 4a in negative z-direction.
    [35] [0035] Fig. 5a-5c shows a cutting device according to Fig. 1, in a secondposition in relation to an exemplary resulting formed/cut material 4. The frameportion 2 has pivoted ca 90° from the starting position of Fig. 3a-3c. Fig. 4b showsthe cutting device 1 and material 4 of Fig. 4a in a y-direction. Fig. 4c shows thecutting device 1 and material 4 of Fig. 4a in negative z-direction.
    [36] [0036] Thus in Figs. 2a-2c, 3a-3c, 4a-4c, 5a-5c, it has been shown one resultingshape of a material 4 from the pivoting and forming of the cutting device 1. Thematerial 4 had initially an essentially rectangular shape in the x-y plane andextended preferably essentially in the z-direction at a length corresponding to thelength of the frame portions 2a, 2b. As a result from the pivoting of the framestructure 2/cutting device 1, a substantially flat lower surface, formed by the 68207 horizontal cutting wires 3a, and an upper surface with a first circular declinetowards the pivot axis p having a radial slope q defined by the angle q of thecutting wire 3b in relation to cutting wire 3a from every point of the upper surface,is created. Thereby, the decline creates a cavity in the plate/material 4 which hasthe shape of at least a part of a blunt virtual cone with the apex of the conedirected towards the pivot axis p. According to one embodiment, the cutting device1 may be employed to instead form a real cone in a similar manner with the slopeof the cone defined by the angle q. According to one embodiment, the cuttingdevice 1may thereby be used to produce a surface covering system, such as forinstance floors or roofs known through WO2013/172775 A1 by the applicant,wherein a plurality of plates of material 4 is arranged to form a floor systems, in anefficient manner, both in terms of time and cost.
    [37] [0037] Fig. 6 discloses an exemplary surface covering system for e.g. a floor ora roof comprising plates that may be manufactured using the cutting device 1.According to one embodiment, the plates are numbered between 1-7, subdividedinto A-D plates depending on their position in the surface covering system, whichcomprises a center point or a drainage point where water is arranged to exit thefloor covering system. Like reference numerals designate identical or similarplates. As noted, plate 1 correspond to the hitherto described formed material 4,i.e. wherein a maximum 90° rotation of the cutting device 1 without any requiredtranslation of the cutting device 1 forms this plate of the surface covering system.Other plates, for instance plates 2-7, requires a rotation of the cutting device1/frame structure 2 which is less than 90°, however, since the entire plate/material4 needs to be formed, this requires a combination of a translation movement and arotation movement of the cutting device 1/frame structure 2.
    [38] [0038] According to one embodiment, the cutting device 1 is arranged to rotate360° around the pivot axis p and thus form material 4 into an entire blunt virtualcone or real cone. Thus, according to one embodiment, the material 4 may have asurface area seen in the z-direction which is four times the area of Figs. 2a-2c, 3a-3c, 4a-4c, 5a-5c. According to one embodiment, the process of cutting suchmaterial 4 may be initiated by a relative axial movement of the cutting device 1 and 68207 the material 4 in the z-direction wherein the cutting wire/s cuts a slot or makes anincision in the material 4 along its extension in the z-direction. Thereafter, therotation/pivoting of the cutting device 1 is initiated wherein the material 4 is furtherformed according to the arrangement/pattern of the cutting wire 3. The plates ofthe floor covering system may thereafter be cut in their desired shapes and sizes.
    [39] [0039] According to another embodiment, the pivot axis p extends at anyposition along the connection portion 2c. According to one embodiment, the pivotaxis p extends at a center point of the connection portion 2c. Thus, even plate 1may be formed/cut by such cutting device 1, since the important aspect here is topoint the extension of the connection portion 2c towards a thought center point, i.e.a drainage point. To be able to carry out this a translation of the cutting device 1may need to be carried out parallel to the rotation of the cutting device 1.
    [40] [0040] A preferred embodiment of a cutting device 1 according to the inventionhas been described. However, the person skilled in the art realizes that this can bevaried within the scope of the appended claims without departing from the inventive idea.
    [41] [0041] All the described alternative embodiments above or parts of anembodiment can be freely combined without departing from the inventive idea as long as the combination is not contradictory.
