Abstract
The present friction spinning apparatus includes a draw frame section with an entrance trumpet including first and second fiber sliver guiding passageways for forming a three component corespun yarn. One of the guiding passageways directs a core roving into the draw frame section while the other sliver guiding passageway directs a core wrapper sliver into the draw frame section so that the core wrapper fibers surround the core fibers. Wrapping fibers are then wound about the core and core wrapper fibers in an elongated throat extending between a pair of rotating suction drums.
