White Fabric Presser Wheel for Studio Singer Silver Reed Artisan Knitting Machines - The white fabric presser wheel part number 06251201 is found on the sinker plate. This wheel presses the fabric back towards the main bed as you are knitting and helps the stitches push back on the needles. This action of the fabric presser wheel counteracts the tendency for the knitting to travel up with the needle as it is pushed forward by the carriage. These white wheels wear down along the sides of each prong becoming star-like in appearance on a machine that is used frequently. Occasionally a prong will break away. This fabric presser wheel is easily replaced and is inexpensive. However, it is an important piece of the sinker plate.
