Abstract
An apparatus for entangling filamentary yarns comprises first and second blocks which are positionable in mutually superimposed relationship. Each block includes a plurality of channels and a plurality of fluid ports. The channels are located so that when the blocks are in superimposed relationship, respective ones of the channels are aligned to define yarn passages through which yarns can be fed. The fluid ports communicate with the yarn passages and are communicable with pressurized fluid to create a turbulent fluid flow within respective ones of the yarn passages for entangling the yarns. A motor actuated mechanism separates the first and second blocks to provide simultaneous and immediate access to the interior of the yarn passages. When the blocks are separated, the yarns can be continually fed therethrough to pull trash through the yarn passages. Each block includes a base section and a head section removably attached thereto.
