Patent ID: 8312908

Claim:
A device for regulating the delivery rate of a linear element for fabricating a tire, wherein the device comprises path-forming means forming a delivery path for the linear element between an inlet to the device at substantially constant delivery rate and an outlet from the device at a rate that varies and that is substantially periodic, the path being of length that is variable in application of a predetermined periodic relationship, said path-forming means comprising: a plurality of deflection pulleys for deflecting the linear element, each pulley being movable in rectilinear translation in a common direction; means for moving each of the pulleys in sinusoidal translation motion with a frequency that is a multiple of the frequency of the delivery rate of the linear element, the frequency of the motion of one pulley, referred to as a driving pulley, being equal to the frequency of the delivery rate of the linear element; means for a motion and frequency coupling of the sinusoidal translation of the different pulleys with frequencies that are different from each other, wherein the frequency of each pulley is an integer multiple of the motion frequency of the drive pulley; and for each pulley, means for adjusting the amplitude of its movement in translation.
