Abstract:
A device for supply of a mat of fibers to an input cylinder of a carder, said device comprising:a slide configured to receive the mat of fibres;a plurality of pivoting tables aligned transversely, said slide having an end that overlaps said plurality of pivoting tables, said plurality of pivoting tables being disposed transversely so as to form first gaps therebetween;a set of feed rollers having a same transverse dimension as said plurality of pivoting tables, said plurality of pivoting tables being positioned opposite said set of feed rollers, said set of feed rollers being superimposed over said plurality of pivoting tables such that a second gap is formed between said set of feed rollers and said plurality of pivoting tables; anda mechanism configured to provide individual, continuous regulation of rotational speed to said set of feed rollers according to a quantity of fibres present in the second gap, whereinsaid plurality of pivoting tables are each provided with an underlying pressure unit that is configured to thrust a corresponding pivoting table with controlled force against a corresponding feed roller, andsaid plurality of pivoting tables are each provided with a level sensor that is configured to supply a signal corresponding to an angular position of a respective pivoting table based upon a quantity of fibres present in the second gap.
