Abstract
A process and apparatus for collecting continuous fibers or filaments as a uniform batt comprises a filament emitter in the form of a spinning die, a venturi, a diffuser, and a fiber collection bed. The filaments move downward after being created by the emitter, and exhaust ports create in the diffuser an airflow having a direction against the flow of the filaments so that the filaments are decelerated before contacting the fiber collection bed.
