<p>The invention relates to a tyre cutting device comprising a frame and at least one blade unit (7, 7a) as well as means for rotating the tyre (1 ) in relation to the blade unit. The blade unit comprises a cutting blade (8, 8a), which is rotatable around its axis (10, 10a) and arranged in connection with the frame with the axis, which cutting blade has a cutting edge (9), and a counterpart (14, 14a), which comprises a cutting edge (17) and which has been arranged in connection with the cutting blade so that the side wall (2, 2a) of the tyre to be cut is arrangeable between the cutting blade and the counterpart. The cutting blade is rotatable in relation to the counterpart so that a shear force is formed between the cutting edge (9) of the cutting blade and the cutting edge (17) of the counterpart, and the counterpart (14, 14a) further comprises a sharp tip part (15, 15a) for arranging the counterpart at least partially through the side wall (2, 2a) of the tyre.</p> |
