Abstract:
A method of spinning which comprises the steps of:(a) drafting a slubbing by passing said slubbing through a drafting frame having rollers at an output side of said drafting frame defining a nip engaging the drafted slubbing;(b) subjecting drafted slubbing in said drafting frame to compaction immediately upstream of said nip by passing the drafted slubbing over a row of perforations under suction to draw fibers inwardly and compact the drafted slubbing entering said nip;(c) passing a compacted drafted slubbing emerging from said nip through a vertically shiftable thread guide positioned axially above a spindle carrying a bobbin sleeve on which a spun thread is to be wound;(d) in a lower position of said thread guide, engaging the compacted drafted slubbing with a balloon-suppressing attachment extending upwardly from said spindle to twist the compacted drafted slubbing between said attachment and said nip substantially without a thread triangle at said nip to form a thread and guide said thread onto said bobbin sleeve through a traveler on a vertically movable ring rail to wind a bobbin thereon with a suppressed thread balloon; and(e) preparatory to bobbin change, displacing said thread guide upwardly to disengage said thread from said attachment and lowering said ring rail to an underwinding portion of said spindle.
