Abstract

Procedimento per realizzare feltri del tipo costituito da un intreccio di fibre formanti anse reciprocamente aggrovigliate e parzialmente saldate comprende le seguenti operazioni; generare da una filiera contenente un materiale termofusibile un fascio di fili discendenti per gravità dalla filiera; raccogliere una porzione di detto fascio su una rete a maglie larghe, che avanza sotto la filiera a velocità costante in direzione discendente, e converge sino ad adagiarsi su una sottostante superficie parzialmente immersa in un bagno di raffreddamento; raccogliere la restante parte di detto fascio direttamente nel detto bagno di raffreddamento subito a valle di detta superficie; estrarre da detto bagno il feltro inglobante la rete, essendo la velocità lineare di detta rete comparativamente molto minore della velocità di discesa dei fili dalla filiera; detti fili venendo raccolti dalla rete e dal bagno allo stato rammollito. L'impianto per fabbricare feltri del tipo sopradescritto comprende mezzi per alimentare una rete di rinforzo a detto rullo in una direzione inclinata discendente verso il rullo e mezzi per registrare la inclinazione di detta rete in guisa da, variarne la linea di tangenza col rullo.
