The plate member 6 is provided with a guiding structure 50 extending along the length of the plate member 6 parallel to the longitudinal axis Y of the plate member 6. The guiding structure 50 can be used to control the motion of a milling cutter or another tool used to cut a groove in a rood structure.

Fig. 3B illustrates another perspective view of the tool 2 shown in Fig. 3A. Fig. 3A and Fig. 3B are almost similar; however, schematically illustrated milling cutters 44, 44 are arranged next to the side portion of the plate member 6. For illustration purposes, the milling cutter 44 is simplified. It can, however, bees seen that the milling cutters 44, 44' bear against the side structure of the plate member 6 and that the tool 2 and the milling cutters 44, 44', hereby, can be used to cut a groove that extends parallel to the longitudinal axis Y of the plate member 6 and perpendicular to the longitudinal axis X of the rod member 4 The plate member 6 comprises a guiding structure 50 protruding from the top surface of the plate member 6 and extending along the length of the plate member 6 parallel to the longitudinal axis Y of the plate member 6. The guiding structure 50 is adapted to be used to control the motion of a milling cutter or another tool used to cut a groove in a rood structure.

Fig. 4A illustrates a schematic view of a tool 2 according to the invention used to cut grooves 38 for gutter brackets in a roof structure 34. The tool 2 is used to assist a cutting process, in which grooves 38 for attachment of gutter brackets are established. The use of the tool 2 ensures that the groove 38 extends perpendicular to the edge 36 of the roof structure 34. Furthermore, the tool 2 makes it possible to provide adjacent grooves 38 with a predefined distance d (see Fig. 4B).

A milling cutter 44' abuts the side portion of the plate member 6 of the tool 2. When the milling cutter 44' is moved along the side portion of the plate member 6 in the direction 42 indicated by an arrow 42, a groove 38 is being cut by means of the milling cutter 44'. Any suitable cutting device may be applied.

The tool 2 comprises a plate member 6 detachably attached to a rod member 5. An insert structure 8 extending perpendicular to the rod member 4 is slidably attached to the rod member 4. The plate member 6 is attached to the rod member 4 by means of attachment structures 24, 26 inserted into corresponding receiving structures (holes 10, 12') provided in the plate member 6. The plate member 6 is provided with a longitudinal guiding structure 50 adapted to guide a cutting or milling device so that the groove 38 may extend parallel to the guiding structure 50

Once a groove 38 has been provided in the roof structure 34, the insert structure 8 can be inserted into the groove 38 Accordingly, rod member 4 extends parallel to the edge 36 of the roof structure 34. The tool 2 comprises a plate member 6 corresponding to the one explained with reference to Fig 2B.

Fig. 4B illustrates a situation, in which a groove 38 has been provided in the roof structure 34 and wherein the insert structure 8 can be inserted into the groove 38. The rod member 4 has been rotated 180 degrees compared with the configuration shown in Fig. 4A. Moreover, The plate member has been rotated 180 degrees A milling cutter 44 abuts the side portion of the plate member 6 Accordingly, when the milling cutter 44 is used (moved in the direction 42) as illustrated in Fig. 4B, an additional groove extending parallel to the first groove 38 in is provided in the predefined distance di from the first groove 38. By adjusting the position of the insert member 8 on the rod member 4, it is possible to adjust the distance di between adjacent grooves (38, 40 see Fig. 4C).

The width of the groove 38 is defined by the geometry of the cutter disk of the milling cutter 44. The width of the insert structure 8 may be selected to fit the width of the groove 38 made by the milling cutter 44 The plate member 6 is provided with a guiding structure 50 extending along the length of the plate member 6 parallel to the longitudinal axis Y of the plate member 6. The guiding structure 50 can be used to control the motion of a milling cutter or another tool used to cut a groove in a rood structure

Fig 4C illustrates a schematic view of two grooves 38, 40 cut by using a tool 2 according to the invention It can be seen that the two grooves 38, 40 are basically rectangular and extend perpendicular to the edge 36 of the roof structure 34. The two grooves 38, 40 extend parallel to each other and are shaped to receive gutter brackets 48. Gutter brackets 48 are arranged next to the grooves 38, 40. By arranging the gutter brackets 48 in the grooves 38, 40, it is possible to countersink the gutter brackets 48. Hereby, the gutter brackets 48 do not protrude from the roof structure 34. When providing a roof structure with roofing felt, it is important to be able to arrange the gutter brackets 48 in a manner in which they do not protrude from the roof structure 34

Fig. 4D illustrates a schematic view of the tool 2 shown in Fig. 4A used to cut and additional groove for gutter brackets in the roof structure shown in Fig. 4A and Fig. 4B. A milling cutter 44 is aligned along the side structure of the plate member 6. Accordingly, when the milling cutter 44 is used and moved in the direction 42, an additional groove extending parallel to the first groove 38 and the second groove 40 is provided in the predefined distance d from the second groove 40. It can be seen that the distance di between the first groove 38 and the second groove 40 corresponds to the distance d 2 between the second groove 40 and the additional groove being cut by the milling cutter 44. By adjusting the position of the insert member 8 on the rod member 4, it is possible to change distance di, d 2 between adjacent grooves 38, 40.

The insert structure 8 is adapted to fit the grooves 38, 40 made by the milling cutter 44. If another cutter disc is used, it is possible to replace the insert structure 8 with another one having another width in order to make the insert structure 8 fit into the groove 38, 40. The plate member 6 is provided with a guiding structure 50 extending along the length of the plate member 6 parallel to the longitudinal axis Y of the plate member 6.
