A flat web of fabric is folded and overlapped into a fabric pack between a pair of perforate belts. The belts carry the fabric pack in a generally U-shaped conveying path. At the bottom arcuate portion of the conveying path, the fabric pack goes through a washing tank and is squeezed between the belts. The fabric pack passes out of the tank and goes between squeeze rolls which force washing liquid through and from the fabric pack. The fabric pack is then pulled from its folded and overlapped condition for passage through exit squeeze means as a flat web of fabric.
