Abstract
A method for producing carpeting of a type having pile yarns adhesively bonded to a backing which comprises providing a thin flexible core member having longitudinal and transverse axes, winding a continuous yarn around the core member in a direction perpendicular to the longitudinal axis so as to form a plurality of elongated loops conforming to the cross-sectional configuration of the core member, positioning the core member having the yarn wound thereon on a backing sheet so that the longitudinal axis is parallel to the sheet and the transverse axis is perpendicular to the sheet and so that one end of each of the loops contacts the backing sheet, adhering the end of the loops contacting the backing sheet to the backing sheet, cutting the other ends of the loops, and removing the core member. Carpeting characterized by good register between different colors and different heights with a high degree of flexibility in the design pattern is obtained by this method.
