摘要

Device for reducing the speed, stopping, and even reversing the movement, transiently in a portion, of a flexible material, of any section, circulating continuously, such as a band, tape, rope, characterized by comprising a pair of main organs of guide of said continuous flexible material, of axes perpendicular to the direction of travel of said material and mounted at a distance from each other appropriate to determine the portion of the material in which it is desired to produce the speed reduction, stopping, or inversion of the movement and to the less another pair of analogous guiding organs of the continuous flexible material, next to each other and located between the said main guiding organs to determine respective inflections of the continuous flexible material, these second guiding elements of the material being mounted on a movable carriage parallel to the direction general running of the material and alternatively between the aforementioned guiding organs p principal according to a cycle divided into two phases, the first of the reduction of the speed, stop and even reversal of the movement of the aforementioned portion of the material, and the second of acceleration of the same up to a speed that compensates the previous reduction, without prior and after the device the speed of advancement of said material undergoes variation.
