Abstract
Abstract A MECHANISM FOR FEEDING A FIBROUS TEXTILE BATT TO A PROCESSING AREA SUCH AS A NEEDLING MACHINE. THE FEED MECHANISM INCLUDES A PAIR OF UPPER AND LOWER FEED ROLLS EACH OF WHICH HAVE SPACED CIRCUMFERENTIAL GROOVES, GROOVES OF ONE ROLL BEING ALIGNED WITH GROOVES OF THE OTHER ROLL. A PLURALITY OF UPPER AND LOWER ELONGATED GUIDE ELEMENTS WHICH EXTEND THROUGH THE GROOVES IN THE UPPER AND LOWER FEED ROLLS, RESPECTIVELY, FROM THE ENTERING SIDE OF THE ROLLS, BETWEEN THE ROLLS AND UP TO THE BATT PROCESSING AREA. THE CIRCUMFERENTIAL AREAS OF THE ROLLS, WHICH LIE BETWEEN THE GROOVES, COMPRESS THE BATT AND ADVANCE IT THROUGH A CHANNEL FORMED BY THE GUIDE ELEMENTS WHICH MAINTAIN THE BATT IN A COMPRESSED STATE UP TO THE PROCESSING AREA.
