Abstract: The plate-like carrier for the absorbent part of a mop is located in a vertical plane while a roller or a blade is caused to move along and in linear contact with successive increments of the absorbent part, either vertically from the upper edge to the lower edge or horizontally from one end to the other end of the carrier. The roller or blade can be moved by a manually operated drive or by a motor through the medium of a carriage.

Abstract: An apparatus for wringing the strands of mops has a housing which supports two lateral carriers for a set of horizontal wringing elements which are installed in the housing and are movable toward and away from the inner side of the front wall of the housing. The wringing elements are pivotable within limits about horizontal axes and have limited freedom of upward and downward movement relative to the lateral walls of the housing so that they can conform the orientation of their profiled front sides to the outlines of adjacent portions of a pile of strands which are introduced into the housing between the front wall and the wringing elements while the carriers maintain such elements in retracted positions. The carriers are formed with horizontal toothed racks mating with gear segments which are rotatably mounted in the housing and can be rotated by a pivotable lever so as to move the carriers and the wringing elements toward or away from the front wall.
