Patent ID: 7082646

Claim:
A revolving flat cleaning and grinding apparatus in combination with a carding machine in which revolving flats are conveyed around an endless path to envelope a part of the circumferential surface of a main cylinder comprising: a precision feeding system supporting a guide track to extend laterally across the span of a revolving flat in the endless path of the carding machine, a carriage supporting a wheel drive to rotatably drive the wheel around an axis perpendicular to the direction of motion of the revolving flat, said carriage being mounted on a guide track and driven to reciprocally traverse the width of a revolving flat, said wheel drive being able to interchangeably drive either one of a cleaning wheel and a grinding wheel, whereby the wheel can be driven in rotation and traversed across the width of each revolving flat, one at a time, as the revolving flats are conveyed around the path, said precision feeding system providing means to precisely adjust the height of the guide track above the revolving flat so that when fitted with a cleaning wheel the wheel acts to clean down to the surface of the revolving flat during normal operation of the carding machine and, when the grinding wheel is substituted for the cleaning wheel, the height of the grinding wheel above the revolving flat can be precisely adjusted so that as the grinding wheel spins and the carriage traverses the revolving flats while the revolving flats are conveyed around the path, the points of the revolving flats are accurately reground.
