The apparatus comprises, inside a protection housing (2), a bobbin holder (3) for a roller material and, in its lower part, a drum (4) intended to receive a cutting device (6), and a pressing element (7) in contact with said drum and between which is introduced the tensioned material to be cut. Locking means (17-19) lock the cutting blade in the drum, in a stop position, and in a starting position of rotation of the drum before the blade comes out, said locking means being arranged on the one hand on the side wing of the apparatus housing at the fixed rack (11), and on the other hand closed to the end plate (15) of the drum facing the heel-forming part, a complementary means (20) arranged on the base of the housing being susceptible to cooperate with the cutting blade to provide for its rocking and retraction into the housing formed on the drum. |
