Abstract

Device to perform the contraction and expansion of the drums for the manufacture of pneumatic covers, whose contraction or expansion is determined by the relative rotation of its two concentric elements, one mounted rigidly and the other rotating on the motor shaft to which they are attached by means of arms the segments constituting the cylindrical part of the drum, provided with means to prevent rotation in both directions of the motor shaft and consequently of the first element integral with it, and means for rotating the second element at a predetermined angle. To the first. (Machine-translation by Google Translate, not legally binding)
