Method and device for the production of fibre ribbons with parallel fibre position out of tangled fibre collectives

摘要

The method for producing slivers with a parallelised fibre position from tangled fibre collectives involves the following method steps:… A) Winding of a preportioned fibre material in tangled form onto a first clothing drum (3);… B) Separation of the preoriented annular fibre fleece wound on the first clothing drum (3) at a specific point;… C) Unwinding of the separated fibre fleece from the first clothing drum (3) at one free end of the fibre fleece;… D) Stretching of the fibre fleece by the factor x;… E) Winding of the stretched fibre fleece onto a second clothing drum (8);… F) Separation of the folded fibre fleece wound on the second clothing drum (8) at a specific point;… G) Unwinding of the separated fibre fleece from the second clothing drum (8) at one free end of the fibre fleece;… H) Stretching of the fibre fleece by the factor x;… I) Winding of the stretched fibre fleece onto the first clothing drum (3);… J) Repetition of method steps B) to I); and… H) Cessation of the repetition cycle after step G. …IMAGE…
