Abstract (en)
[origin: US5495638A] PCT No. PCT/EP92/01294 Sec. 371 Date Dec. 7, 1993 Sec. 102(e) Date Dec. 7, 1993 PCT Filed Jun. 9, 1992 PCT Pub. No. WO92/01275 PCT Pub. Date Dec. 10, 1992.A sweeping unit for a sweeping machine to clean a floor area, has a driven pair of closed loop sweeping belts for engaging the floor, the driven sweeping belts including a first portion fixed in position relative to a mounting platform and a second movable portion. First rollers constrain the first portions of the driven sweeping belts relative to the mounting platform, and second guide rollers, which are movable relative to the mounting platform, constrain the second portions of the belts, respectively. The width of the floor area that is swept when the sweeping machine moves in a working direction, is variable as the second guide rollers are moved manually or automatically. The sweeping unit may be combined with a scrubber device having similar width adjustment features.
