Abstract
A machine for making carpeting in which rows of lengths of yarn are bonded to an adhesive surface of a backing web has a gripper station at which yarn ends are presented in a row and are drawn out a predetermined distance, the drawn length of yarn being engaged to support them and then cut off. The cut lengths are then transferred to an assembly station where they are placed on the adhesive surface of the backing. The yarn lengths are pressed against the adhesive surface by a bladed member. The means engaging the drawn yarn lengths to support them comprises, in a preferred version, a bar extending along one side of the row of yarn ends and provided with a multiplicity of pins for impaling the yarn lengths, and a bar on the other side of the row with holes corresponding to the pins for pressing the yarn lengths on to the pins. The means for engaging the drawn yarn lengths may alternatively comprise a bar with holes in it and a device for applying suction to the holes to hold the yarn lengths against the bar by suction.
