Abstract

L'invenzione propone un nuovo procedimento e dispositivo per controllare la portata di alimentazione di una carda o macchina simile secondo il quale si inviano dei raggi X (2) attraverso una falda (4) di fibre, si misurano i raggi non captati dalle fibre e si regola la portata della fibre in entrata nella carda in funzione dei raggi misurati. Il generatore (1) di raggi X è munito di un sistema di regolazione automatica (6) delle tensioni applicate al tubo (5) a raggi X in modo da produrre una radiazione (2) stabile. Il sensore è un tubo a scintillazione (3) che di preferenza è munito di una regolazione che tiene conto dello stato di invecchiamento del cristallo (12).The invention proposes a new method and device for controlling the feeding capacity of a carding machine or similar machine according to which X-rays (2) are sent through a layer of fibers (4), the rays not picked up by the fibers are measured and the flow rate of the fibers entering the carder is adjusted according to the measured radii. The X-ray generator (1) is equipped with an automatic adjustment system (6) of the voltages applied to the X-ray tube (5) so as to produce stable radiation (2). The sensor is a scintillation tube (3) which is preferably equipped with a regulation which takes into account the aging state of the crystal (12).
