7 Claims

1. Improved device for tire disassembling machines (1) designed to simplify tire assembling without excessive stretching, which comprises: a base (2), a self-centering unit (4) rotatably mounted on the base (2) around a rotation axis (14), to stop and drive into rotation, a wheel (R) comprising a tire (P) mounted on a corresponding rim (C), an articulated arm (12) composed of a first section (12a) articulated according to a first vertical axis (11) and a support side (10) with adjustable height with respect to the base (2) of the tire disassembling machine (1), and a second section (12b) with a sliding heel-pressing tool (A) articulated with the first section (12a) by means of a joint (S) with a second vertical axis (13) placed at a distance from the said first vertical axis (11) equal to the distance between the said first vertical axis (11) and the rotation axis (14) of a self-centering unit (4), wherein said second section (12) of the arm rotates around said second vertical axis (13) so that the heel-pressing tool (A) rotates together with the tire (P), further having cam and valve train means (M) designed to determine the gradual automatic lifting of the said heel-pressing tool (A) in a predefined point of its rotation together with the tire (P), during the assembling operation of the tire on the corresponding rim (C).
