Abstract: A system for properly opening, shaping, orienting and positioning of bands in high speed banders. A number of jet nozzles are attached to moveable arms, which hold the bands during placement, and compressed gas is blown through these nozzles to open and shape the bands. A second set of nozzles are located on a guiding member which helps position and shape the band, and these nozzles guide bursts of compressed gas toward the inner back region of the band just prior to placement.

Abstract: A separator of particulate material from fluid or gas or fluid mixture systems comprising a separator housing having intake and discharge openings formed therein. The intake opening of the separator housing is in communication with the medium in which the particulate material is suspended. The discharge opening of the separator chamber is in communication with a cyclone type settling chamber. A by-pass line extends from the upper end of the settling chamber to the conduit which is supplying the medium to the separator housing. A plurality of closely spaced hollow discs are rotatably mounted within the separator housing and are rotated by means of an electric motor or the like. A fan apparatus is in communication with the interior of the separator housing and is adapted to draw the medium from the intake opening, thence through the space between the discs, then longitudinally through the center of the discs to a point of discharge.
