ABSTRACT:
A bead release device for tire removal machines comprises an arm (60) which at one end is intended to be hinged on a vertical axis (6) to the base (1) of a tire removal machine (100), while at its other end it supports a positionable bead release tool (66), the arm being coupled with unilateral engagement to the rod (9) of a pneumatic cylinder-piston unit which is associated with the base, the unilateral engagement being achieved by a plurality of aligned equidistant identical notches (111) provided in the end longitudinal portion of the rod and by a coupling member (18) which is provided on the arm (60) and is arranged to occupy a rest position in which it allows the arm (60) and the rod (9) to slide freely relative to each other, and a working position in which it maintains the arm and rod coupled together.
