Abstract

Aparato para picar fibras de vidrio, que tiene una trituradora en el blindaje de una contrarrueda para mecanizar su superficie y compensar el desgaste. Para producir material de filamento termoplástico triturado, y especialmente fibras de vidrio picadas, una rueda de corte (13) trabaja con una contrarrueda (14) que giran juntas para picar los filamentos entre ellas. Al menos parte de la superficie periférica de la contrarrueda gira y está en contacto con la rueda de corte, con una mecanización que compensa su desgaste. Al trabajar, el espesor de la contrarrueda se reduce y la superficie se desgasta Los filamentos se extraen por las acciones combinadas de la contrarrueda y de la rueda de corte. Antes del corte, los filamentos se tienden sobre la superficie periférica de la contrarrueda. Los filamentos se producen en un proceso de hilado continuo. Se incluye una reivindicación independiente por un aparato con al menos una contrarrueda y una rueda de corte, en contacto mutuo. Al menos la superficie exterior de la contrarrueda está mecanizada. Características preferidas: La contrarrueda es un cilindro con blindaje (17) sobre al menos parte de su periferia, utilizando un material polímero. La contrarrueda está mecanizada con un amolador abrasivo (19), como cilindro metálico (20) con gránulos de diamante abrasivo en la superficie, que se mueve sobre la superficie de la contrarrueda. La superficie de la contrarrueda es monitorizada por un sensor óptico, aun sensor para medir la rugosidad de la superficie, o un control de calidad del filamento picado. El polvo de la pulverización se extrae utilizando al menos un chorro de succión (22), preferiblemente aguas abajo del amolador.
