    • A process and device for the manufacture of plastic fiber boards made of balls of expanded glass, expanded clay, pumice granules, mica, or a similar material and a foamed organic binder, such as epoxy resin, PU phenol resin, or the like. The binder is mixed with the balls, foamed, and hardened in a matrix space formed between two mold plates (1, 2) positioned at a distance one from the other. In order to obtain a particularly light but stable plastic fiber board, uniformly distributed recesses opening toward the internal sides of the plates are provided to contain the mixture located between the two mold plates during compression and before hardening. The device employed to implement the process includes two mold plates (1, 2), which are brought together in a press to compact the introduced therebetween. The inner surface of each mold plate (1, 2) is provided with a plurality of uniformly distributed, conical mold bodies (4, 5), whose cross-sections running parallel to the mold plate surface decreases in the direction of the other mold plate.

    • Relatively long plastic microfilaments are used to make reinforcing, filler materials and fabrics. A blowing gas is applied at a positive pressure to the inert surface of a liquid plastic film formed across a coaxial blowing nozzle to blow the film and form an elongated hollow tube having a thinned wall or weakened portion. An entraining fluid is directed at an angle over and around the blowing nozzle and as it passes over and around the blowing nozzle, it dynamically induces a pulsating or fluctuating pressure field at the opposite side of the blowing nozzle in the wake thereof and produces a laminar flow of entraining fluid in the vicinity of the forming elongated tube. The continued movement of the entraining fluid over the elongated tube produces asymmetric fluid drag forces on the tube, and at the thinned wall or weakened wall portion longitudinally breaks the tube to form a multiplicity of plastic microfilaments, and detaches the plastic microfilaments from the elongated tube and from the coaxial blowing nozzle and the detached microfilaments are carried away from the blowing nozzle. Quench nozzles or heating nozzles may be disposed below and on either side of the blowing nozzle to direct cooling or heating fluid at and into contact with the plastic microfilaments to cool or heat and cure, solidify and harden the plastic to form hard, smooth plastic microfilaments.
