Cleaning device for textile carding machine
Abstract
Abstract THE MACHINE IS PROVIDED WITH A CLEANING DEVICE COMPRISING A DRIVING CYLINDER AND A HOLLOW PRESSURE CYLINDER DISPOSED PARALLEL TO AND TANGENTIALLY ALONG THE DRIVING CYLINDER. THE PRESSURE CYLINDER IS MAINTAINED BY SIMPLY RESTING TANGENTIALLY ON THE DRIVING CYLINDER AND ON RETAINING ROLLERS CARRIED BY THE FRAME, SO THAT THE PRESSURE CYLINDER IS IN A STABLE SITUATION. THE HOLLOW PRESSURE CYLINDER IS TRAVERSED BY A NON-ROTATABLE APPLICATION BAR MOUNTED ON THE FRAME WITH THE POSSIBILITY OF MOVING AWAY FROM ITS SUPPORTRING SURFACE AGAINST THE ACTION OF RETURN SPRINGS. THE APPLICATION BAR COACTS WITH THE HOLLOW PRESSURE CYLINDER EXCLUSIVELY BY THE INTERMEDIARY OF A PLURALITY OF APPLICATION ROLLERS SUBJECTED TO THE ACTION OF ELASTIC SUSPENSION MEANS. THESE APPLICATION ROLLERS ARE PLACED AT INTERVALS ALONG THE APPLICATION BAR AND BAR AGAINST THE INTERNAL WALL OF THE PRESSURE CYLINDER ALONG A GENERATRIX OF CONTACT. THE OVERALL FORCE OF THE SUSPENSION MEANS IS SMALLER THAN THE FORCE OF THE RETURN SPRINGS OF THE APPLICATION BAR.
