    摘要： An extruder head for use in forming at least one strip of polymeric material. The extruder head includes a flow channel having a flow inlet end and a flow outlet end. A flow diverter is removably secured within the flow channel of the extruder head. The flow diverter is held securely in place within the flow channel by a fastening mechanism, and the flow diverter can be easily removed from the flow channel for reshaping or reprofiling as may be necessary to achieve a desired velocity profile of polymeric material flow at the flow outlet end of the flow channel.

    摘要： A filter mesh assembly configured to control particulate material in a filter assembly of a plastic extruder. The filter mesh assembly includes a wire mesh filter having a square weave construction defining a predetermined pore size with the wire mesh filter having flattened surfaces of adjacent wires on the same plane and configured to allow a portion of the scraper to move across the wire mesh filter assembly. The assembly also includes a wire mesh supporter having a square weave construction and a characteristic of sufficient strength to support the wire mesh filter against a breaker plate. The wire mesh filter and the wire mesh supporter are diffusion bonded to each other as a unified structure and disposed in a housing between an inlet and breaker plate. The configuration allows passage of molten plastic through the breaker plate and lateral movement of material, parallel to the breaker plate.

    摘要： The object of the present invention is to produce plural resin forms at one time with stability by dividing resin starting material continuously in a short time and with the same residence time into plural parts having desired amounts of resin and discharging to solidify them. The producing method is comprising, providing a liquid partition on the die land and/or die lip of a coat hanger shaped die along with the flow direction, introducing starting material for resin into said coat hanger shaped die and dividing it into plural parts and then discharging and solidifying on the adherent.

    摘要： The present invention provides a portion of a die assembly (20) for use in the extrusion of foamed polystyrene. The die assembly includes a first plate (21), a second plate (22), and an insert (23). The first plate has an upstream face (24), a downstream face (25), and a first opening (26) extending between the two first plate faces. The walls (28) of this opening are divergent in a downstream direction. The second plate has an upstream face (29) arranged to abut the first plate downstream face, a downstream face (30), and a second opening (31) extending between the second plate faces and communicating with the first opening. The second opening is bounded by non-divergent walls (32). The insert has a forward marginal end portion mounted on the first plate in the first opening, and has a rearward marginal end portion arranged in the second opening. The insert has a leading edge (33) that is spaced substantially equidistantly from the first opening walls in the vicinity of the first plate upstream face by a distance (D), and has a rear edge (34). The rear edge has a transverse cross-section configured and arranged such that a distance between adjacent portions of the rear edge and between the rear edge and the second plate opening walls in the vicinity of the second plate downstream face is no more than a predetermined distance (d). The velocity profile of foamed polystyrene passing sequentially through the first and second plate openings is increased in length or amplitude and distributed substantially uniformly across the transverse cross-sectional area of the second plate opening in the vicinity of the insert rear edge.
