Abstract

1,175,631. Mixing apparatus. WERNER & PFLEIDERER. 12 Jan., 1968 [13 Jan., 1967], No. 1954/68. Heading B1C. Apparatus for working plastics material comprises a casing containing one or more rotary mixing elements consisting of sections 6 (which may be exchangeable), each section having a film-forming web 7 and a conveying web 8. The web 7 may be straight as shown, arcuate or V-shaped (see Figs. 9 and 10, not shown); if straight it may be angled to the conveying web (see Fig. 11, not shown) or parallel to the rotational axis and in the latter case it may adjoin a conveying web on the next section, or a film-forming web to make a continuous bar (see Fig. 7, not shown). Conveying webs may be of the same or different pitch angles; consecutive sections may be of the same or different lengths; webs may be of the same or different heights and arranged to effect progressive reduction in the thickness of the film. The discharge ends of the webs may adjoin a segment-shaped seal (see Figs. 12 and 13, not shown). Conveying webs on successive sections may have opposite pitches (see Fig. 8, not shown).
