Abstract

Improvements in the textile fiber drawing devices, comprising, between a pair of feeding rollers and a pair of stretching rollers, at least one fiber control cylinder of the so-called hedgehog type, that is, provided with teeth inclined backwards in relation with the direction of rotation of said hedgehog and with the direction of advance of the veil or mass of fibers dragged by the stretching cylinders at a linear speed higher than the peripheral speed of the hedgehog, which is driven to rotate in a positive direction, whose stretching device It is characterized in that at least the active posterior face of the hedgehog's teeth presents a concave profile in the form of an envelope of the circle.
