Abstract:
A device for collecting and drawing a web of fibers from a carder having, in sequence, a doffer, an unloading cylinder, a compactor unit, and a belt conveyor, said carder being configured to concentrate the web of fibers into a strip having a width which corresponds to a width of a gap through which the strip is passed to a discharge unit wherein the discharge unit comprises:a pair of unloading calenders driven by a drive unit so that the unloading calenders draw the strip at a linear speed which is greater than a linear speed of the strip at an output of the compactor unit; anda control unit configured to control the linear speed of the drawing of the strip by the pair of unloading calenders relative to the linear speed of the strip at an output of the compactor unit in order to simultaneously carry out concentration of the web of fibers into the strip and the drawing of the strip between the pair of unloading calenders.
