Abstract

L'invention concerne une machine de tamisage à arbre de serrage qui comprend un premier support transversal (2) qui présente un premier système mobile ainsi qu'un deuxième support transversal (4) qui présente un deuxième système mobile, le premier et le deuxième systèmes mobiles étant disposés de façon à pouvoir se déplacer l'un par rapport à l'autre. Au moins un mat de tamisage (5) fixé à la fois sur le premier support transversal qui lui est associé et sur un deuxième support transversal qui lui est associé est prévu pour obtenir un écrasement et un gonflement alternés des mats de tamisage (5). Pour garantir la durabilité des mats de tamisage fin malgré l'effet de coup de fouet, on réalise, selon l'invention, le mat de tamisage (5) comme mat de tamisage fin fabriqué à partir d'un tissu en matière synthétique et de le relier par au moins à chaque fois un élément de raccordement (6, 7, 8) à un premier support transversal (2) et/ou à un deuxième support transversal (4) qui présente un plus grand allongement à la rupture que le mat (5) de tamisage fin fabriqué à partir d'un tissu en matière synthétique.
