Abstract: Method to provide a novel air textured yarn by combining a cold drawn core yarn and a false twisted effect yarn in a fluid tangling zone.

Abstract: Apparatus and method to provide a novel false twisted slub yarn by combining a core yarn and an effect yarn in a fluid tangling zone. The linear velocity of the core and effect yarns is alternately raised and lowered to allow slubs to be produced in the combined yarn in an air jet apparatus.

Abstract: A device for scrubbing surfaces having two crank-rocker mechanisms wherein a scrubber element is mounted on the rocking link of each crank-rocker mechanism, the scrubber elements having recessed portions arranged so that as the crank-rocker mechanisms operate, the scrubbers scrub overlapping areas but do not collide.

Abstract: A device for scrubbing carpets having an augularly oscillating scrubber mounted on a frame.

Abstract: An improved circular knitting machine which provides for semiautomatic doffing of large diameter rolls of knit fabric. The doffing of the fabric can be accomplished by a woman operator without strain. The improved circular knitting machine provides a quick disconnect from the drive to take the tension of the machine to allow machine repair without extensive dismounting of the machine.

Abstract: An improved circular knitting machine which provides for semi-automatic doffing of large diameter rolls of knit fabric. The doffing of the fabric can be accomplished by a woman operator without strain. Further, the improved circular knitting machine provides an oxbow rod to prevent pattern skewing and a control means to coordinate the fabric take-down speed with the fabric take-up speed. The semi-automatic doffing apparatus includes a doffing handle, the inside of which is grooved to accommodate the take-up roll shaft, so that the full roll of fabric can be easily removed from the knitting machine.

Abstract: An improved circular knitting machine which provides for semiautomatic doffing of large diameter rolls of knit fabric. The doffing of the fabric can be accomplished by a woman operator without strain. The knitting machine has a unique spreader bar to allow slitting of the fabric for inspection purposes while the fabric is being knit. The unique spreader bar includes a support member having a wheel member and a convex portion adjacent the wheel member to guide a fabric around the wheel.

Abstract: A circular knitting machine having a step attached to the machine which is accessible when the machine is in operation but moves out of the way when the knitting machine guard is opened to gain access to the interior of the machine.
