Abstract
The present invention relates to a process for start spinning or piercing at least two yarns of fibers, which process includes forming strands for start-spinning or piecing by introducing a continuous filament into each roving, false twisting the strands, assembling the strands at a given point of convergence, cutting each filament upstream of its introducing point, removing the filament from the strands and twisting the strands without the filament to a twisted yarn. This process serves to overcome the problem of breaking at the start of the spinning. Also by the present invention, the problem of breaking while twisting the assembled intermediate yarns to a twisted yarn is avoided by introducing a false twisting of the assembled intermediate yarns, supplementary to the false twisting of the intermediate yarns, before the last twisting.
