Abstract: The apparatus has two pairs of long driven nip rolls on which bobbins with residual roving are advanced axially in a row with the nip rolls engaging the ends of residual roving and unwinding the roving into a delivery plenum therebelow through which the roving is drawn by suction to the surface of a rotating perforated delivery drum through which the suction is drawn to retain the roving thereon as the drum rotates the roving to a discharge plenum in which a shredding drum shreds the roving for discharge in pieces through a discharge plenum. A baffle plate is mounted closely adjacent the delivery drum to confine suction through the drum and to allow roving to be transported on the delivery drum between the drum and the plate, and extends adjacent the shredding drum to confine the roving thereto. In one embodiment, the baffle plate is perforated to allow suction to be drawn through the plate into the drum and to direct roving to the shredding drum.

Abstract: An apparatus and method for separating entrained particulate matter from a fluid wherein particulate matter is collected in an overlying porous layer on an upstream side of a rotatable, fluid-permeable filter in a first chamber, and rotatably conveyed into a second chamber and used as an additional filtering medium. The filter comprises a cylindrical drum having a filter surface thereon and is rotatably mounted in an enclosed housing having a fluid inlet and a fluid outlet. Fluid pumping means operatively communicate with the housing for inducing a flow of fluid into the housing through the inlet and out of the housing through the outlet. Chamber means are disposed within the housing and sealingly cooperate therewith and with the cylindrical drum and define a first chamber fluidly communicating with the inlet and a predetermined portion of the cylindrical drum on the upstream and downstream sides thereof.
