Abstract
An apparatus and related process for entangling a fibrous web which employs columnar fluid jets to eject a continuous curtain of fluid in an entangling station. The web is advanced through an entangling station on a conveyor which supports an entangling member having a symmetrical pattern of void areas. Baffle members disposed in the void areas are provided which include radiused curvatures and define apertures having a frusto-conical configuration. Dynamic forces in the fluid curtain impact the web in discrete and controlled patterns determined by the baffling members to enhance efficient energy transfer and web entanglement. Textile-like fabrics having a uniform, non-apertured, surface cover are obtained by coaction of fluid curtain and baffle structures.
