ABSTRACT:
Disclosed is a cam pump with two sets of driving and driven pump cams, which receive polymer melt from an extruder and exit the polymer melt through two exit channels in a sequence of 1/2 volume unit, followed by a 0 volume unit, followed by 1 volume unit for one exit channel and simultaneously in a sequence of 1/2 volume unit followed by a 1 volume unit, followed by 0 volume unit for the second exit channel. The cam pump is used in a apparatus for melt mixing and spinning synthetic polymers for the manufacture of yarns with a multiplicity of bundles of filaments, whereby the properties of all filaments in all bundles alternate along their length and the properties of the filaments of each bundle of adjacent bundles alternate between the adjacent bundles.
