Abstract

A system for the uniform distribution and delivery of foam finish to a fabric is disclosed. The system includes a pressure manifold for delivery of foam under pressure to a moving fabric which includes inner and outer concentrically disposed conduits. The inner conduit receives foam under pressure from both ends and has an effluent port along the length thereof supplying foam to the outer conduit. The outer conduit includes a slotted port along the length thereof for delivery of foam under pressure to a moving fabric passing across the slotted port. The pressure manifold may include a sleeve which is adjustably positioned to seal the end portions of the slotted port depending on the width of the fabric being foam finished. The system may include two such pressure manifolds, arranged in parallel crosswise to the moving fabric, to apply foam simultaneously to both sides of the fabric. The foam delivery system may also include a photocell and its associated circuitry to sense the width of the fabric being finished and a pneumatic cylinder mechanically connected to the sleeve and responsive to a signal output from the photocell circuit to adjust the position of the sleeve so that the latter is in close contact with the selvage of the moving fabric.
