Abstract
A cleaning apparatus or arrangement for cleaning a set of flats of a revolving flats card has a pivotable brush for engaging the strips or strip accumulations of the flats and a suction device arranged behind or downstream of the pivotable brush considered with respect to the direction of movement of the flats. According to the invention, a suction nozzle of the suction device is reciprocable over the length or transverse extent of the flats. By means of this arrangement, there is obtained a suction action affording a great cleaning or stripping effect at the flats despite a considerable reduction in the energy required to create the suction action in comparison with heretofore known flat cleaning or stripper arrangements.
