ABSTRACT:
An apparatus and a method for texturing blended synthetic multifilament yarns, wherein the blended yarns are each produced in parallel from a plurality of individual yarn components. The individual yarn components are withdrawn and drawn by a withdrawal means, with a guide means being associated to the withdrawal means for combining the individual yarns to the blended yarns. The blended yarns are separately textured, and to obtain for each of the blended yarns a combination of the individual yarn components that is as identical as possible, the individual yarn components are divided into groups, with each group being reciprocated by one of a plurality of individually controlled traversing yarn guides. The groups of the individual yarn components are guided independently of one another while being reciprocated, with each of the individual yarn components per group being respectively associated to the blended yarns.
