Abstract

Aparato para abrir fibras en una máquina de hilatura de extremo abierto que comprende una caja o alojamiento, un rebajo formado en dicha caja y que define una superficie de colocación de las fibras, un rodillo de apertura montado de tal modo que puede girar en el rebajo y que tiene una superficie periférica de la que sobresalen una pluralidad de dientes, estando contenidas las puntas de cada uno de los dientes en una superficie cilíndrica imaginaria y terminado equidistantes de la superficie de colocación de las fibras, cooperando la superficie periférica del rodillo de apertura con la superficie de colocación de las fibras para definir un conducto de transporte de las fibras, caracterizado por el hecho de que tal generatriz de la superficie periférica es cóncava de tal modo que la distancia radial entre la generatriz y la superficie cilíndrica imaginaria alcanza un valor máximo en una posición intermedia de la longitud de la generatriz.
