A compacting apparatus, especially for open width knitted fabrics. Cooperating feeding and retarding rollers are spaced closely together, separated by entry and exit side compactor blades extending between them and defining angular compacting zone where the fabric transfers from the feed roller surface moving at a first speed to the retarding roller surface, operating at a slower speed. An inflatable element applies pressure across the width of the entry side blade, to urge it toward the feed roller. Fabric is pressed across its full width by a corner area of the entry side blade which also forms the entrance to the compacting zone, providing essentially a line contact between the blade and the roller for highly efficient feeding of the fabric. Steam is injected on the fabric inches in advance of the compacting zone, while the fabric is traveling over the feed roller, resulting in extraordinary efficiencies in the consumption of steam during operations. The use of double bearings at each end of the feeding and retarding rollers enables small diameter rollers to be utilized in machines of very large width, with multiple attendant advantages.
