摘要

Improvements in the apparatuses for crushing foreign bodies in the layers of textile fibers, characterized in that the pressing effect for the crushing is carried out by means of a pair of cylindrical rollers with a smooth surface, with axes parallel to each other and located on the same plane ideal inclined with respect to the vertical, the axis of the lower roller being coupled to a rotary motor system, while the upper roller is free to rotate by frictional drag when interposed the textile web between the two rollers, both rollers being mounted between two end heads, so that the lower roller has the axis mounted in an invariable position, and that the upper roller is variable position by means of respective pressure devices adjustable at will by means of a threaded pin in its head and coupled at its upper end to a manually operated element, whose pin is applied in a spring that pushes a movable bearing in the direction radially the axis of the roller mounted on it, all this so that the textile fibers pass between the two rollers, requested by the rotation of the same in opposite directions, crushing any body that exceeds the thickness of the nappa, and of luck that the eventual appearance of a body of superior hardness compresses the springs in damping action.
