The inventive cutting arrangement comprises a cutting blade or two half-blades (40a, 40b) each of which consists of a generally triangular tip (43, 43a, 43b) arranged on a plane substantially forming a right angle with a reference plane P, of a plate (43, 43a, 43b) which has a determined length (r) and arranged on a plane substantially parallel to said reference plane P and of an edge (41, 41a, 41b) arranged on a plane forming a determined acute angle (a) with the reference plane P. A tyre assembling method using said cutting device for cutting the sets of pre-assembled profiles and to superimposingly produce joints by directly superimposing the same type of products on each other is also disclosed. |
