FIELD: process engineering.
SUBSTANCE: mounted and clamped tire is rotated to cut it in crosswise and lengthwise directions. Note that handling is carried out in two stages. First, tire tread section is cut off and removed. Remaining side strips 2 are compressed together and clamped to them to be cut off bead ring 4. Note also that both said stages are performed in one cycle by means of one cutting tool, that is, drive saw blade 6. Note that in cutting said tread 2 and side trip 3, said saw blade 6 is brought horizontally to make some crosswise cuts 6 along tire outer surface on cutting in and turning tire. Then saw blade 6 is arranged at the level corresponding to tire OD reduced by treat height while, in cutting side strips, it is kept at the level corresponding to tire mounting diameter increased by height of bead ring 4. Then saw blade cuts in tire body to tire vertical axis to start rotating the tire to cut off rubber outer layer.
EFFECT: expanded performances, higher efficiency.
