Apparatus for supplying parallel lengths of fibrous material
Abstract
Abstract A MACHINE FOR SUPPLYING PARALLEL LENGTHS OF FIBROUS STRANDS FOR INCORPORATION IN A NON-WOVEN FABRIC. A GUIDE CARRIAGE RECIPROCATES BETWEEN A PAIR OF CONTINUOUSLY MOVING CONVEYORS HAVING STRAND ENGAGING HOOKS. THE CARRIAGE LAYS A BAND OF STRANDS, FIRST AROUND A SET OF HOOKS OF ONE CONVEYOR AND THEN A SET OF HOOKS ON THE OTHER CONVEYOR. BEFORE EACH CROSSING OF TE CARRIAGE, A RAKE ADJACENT EACH CONVEYOR EXTENDS EACH STRAND, RELATIVE TO THE CONVEYOR, A DISTANCE OF ONE BAND WIDTH FROM A FIRST HOLDING ELEMENT TO A SECOND HOLDING ELEMENT UPSTREAM OF THE SAME CONVEYOR. THE CARRIAGE, RAKE, AND CONVEYORS ARE OPERATED IN TIMED RELATION SO THAT THE LENGTHS OF STRANDS EXTENDING BETWEEN CONVEYORS WILL ALL BE PARALLEL FOR PRESENTATION TO FABRIC FORMING MEANS.
