Abstract

Abstract 1. A method of manufacturing a cut, pile fabric on a machine having an elongated rotably mounted rotor member having a plurality of rows of apertures therein with the rows of apertures extending in the axial direction of the rotor member comprising the steps of: providing a plurality of yarn supplies of a first color adjacent the rotor member, providing a plurality of yarn supplies of a second color at an angle to the yarns of a first color adjacent the rotor member, supplying certain selected yarns of the first color into certain apertures of one row of the rotor member, severing the certain selected yarns of said first color from its supply, rotating the rotor to a position whereat the apertures of the one row are adjacent the yarns of a second color, supplying certain selected yarns of the second color into other apertures of the one row of apertures of the rotor member, severing the certain selected yarns of said second color from its supply, rotating the rotor member to a position where the one row of apertures is adjacent a yarn receiving adhesive member and simultaneously inserting said first color yarn and said second color yarn from the one row of apertures into the adhesive member.
