A new way to blend long-glass fibers into plastic melt without either abrasive machine wear or damage to the fibers is offered by Entex Rust & Mitschke GmbH in Germany (represented here by Triad Sales, Greer, S.C.). Entex uses its planetary-roller extruder to melt the resin and feeds the melt into the gap between a pair of large-diameter, counter-rotating rollers, where the cut fibers are added. One roll is heated and the other chilled. Melt adheres only to the hot roll and is compressed into the gap with a folding motion. The glass is fed into the gap oriented parallel to the roll axes. Entex suggests that the compound could be discharged onto an embossing roller with small lenticular plates to produce free-flowing granulate. It could also be discharged as a thick log for compression molding while still hot. Entex presented the unusual blending process at the K 2007 show in Germany last October. It has been used for rubber processing, but not for thermoplastics. (864) 879-3011 • www.entex-bochum.de
