摘要

Apparatus for the start-up of synthetic or artificial fibers in minimum lengths, perfected for the start-up of synthetic or artificial fibers in minimum lengths, to be used from a starter of at least two sectors of drawing on a machine that has elements of cuts of the fibers, characterized by being constituted by a system formed in combination by two groups of cylinders, each of which is arranged in a symmetrical manner with respect to the plane of symmetry of the system, and perpendicular to the direction of advance of the fiber belt, each group being formed by a pair of lower driven cylinders and motor, which have smooth or fluted surfaces of different diameters, in which the lower cylinders of the system, which have a larger diameter, are located on the outside, on each of the pairs of the lower cylinders, resting on a pressure cylinder, covered with flexible material, concretely, cylinder held and pressed against the pair of lower cylinders and through adjustable pressure elements that collaborate with other devices capable of modifying the direction of the line of action of said pressure, in order to distribute it evenly between the pair of cylinders. Lower cylinders or to increase the pressure that gravitates on one of said lower cylinders and decrease the one that falls on the other, having also provided elements to vary the load of the pressure cylinder in the two groups in an identical manner and make varying the direction of the line of action of the two groups of cylinders substantially symmetrically with respect to the plane of symmetry of the apparatus perpendicular to the line of advance of the tape.
