Abstract
A device for adjusting the delivery rate of a linear element. The device forms a delivery path for the linear element between an inlet to the device at a delivery rate that is substantially constant and an outlet from the device at a delivery rate that is variable and substantially periodic and varies the length of the path of the linear element in application of a predetermined periodic relationship. The device includes a plurality of pulleys movable in rectilinear translation periodically in sinusoidal manner.

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 the pulleys and arranged to move them in sinusoidal translation motion of period that is a multiple of the period of the delivery rate of the linear element, the period of the motion of at least one pulley, referred to as a driving pulley, being equal to the period of the delivery rate of the linear element;
- means for coupling the movements of the pulleys, said means being arranged in such a manner that the motion 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.
