    摘要: A tensioning system for a cleaning blade having a frame, a blade support, and a ratchet system. The blade support is movable around a first axis in a first direction to increase cleaning blade pressure and an opposite second direction. The ratchet system has (a) a first ratchet assembly with at least one ratchet surface facing in a first circumferential direction and (b) a second ratchet assembly having a first plurality of ratchet surfaces facing in a second circumferential direction. At least a part of one of the first and second ratchet assemblies is deformable to allow the blade support to pivot in the first direction to cause the one ratchet surface to (a) move past each of the ratchet surfaces of the blade support moves in the first direction and (b) abut one of the ratchet surfaces to block movement in the second direction.
