Knitting Machine Sponge Bar

Knitting Machine Sponge Bar. These are not cheap sponges only - all sizes are one price.and have metal backing attached to the sponge bar. Plastic bed models do not require metal backing sponge bars. Sponge bars are commonly called needle retainer or compression bar. This item supplies back up pressure for needles to hold them in place while allowing needle movement. Eventually (over several years) the foam rubber will lose its elasticity and the foam rubber decomposes and collapses. Sponge bars should be examined and replaced whenever the foam rubber loses 1/2 its original height (typically3-5 years. If your machine starts dropping a stitch or the carriage jams, you may need a new sponge bar. When ordering, please be sure to include your machine name & model number - it does cut down on errors. If you are not sure of your selection, please call or E-mail us before you order. Knitting Machine Parts & Accessories, Needle Retainer Bar, Sponge Bar, Knitting Machine Parts,Studio, Brother, KintKing, Empisal, Toyota, Sponge Bars include the Metal Back except Studio LK150, LK100, LK140, and Brohter models KX350 and KX400 Sponge Bars.
Also available is a "sponge only".  "Sponge Only" bars are often used for rebuilding your own sponge bar when a sponge bar for your machine is no longer being manufactured. These Sponge are 39" long which is long enough for a standard gauge knitting machine. Included are instructions for rebuilding your own sponge bar. These sponges are NOT made from craft store or insulation foam but are manufactured specifically for knitting machines. They are made of a special long lasting Hi-Density foam that has a fabric covering to make it last. If your machine is not listed, please Email us as it was probably just an error of omission.
  • Toyota knitting machines use a special design sponge bar for machines that use extension rails. If you use extension rails with your Toyota machine, you will need to rebuild your old sponge bar. None are available that will allow use of extension rails.

  • Some knitting machine sponge bars are no longer made - those include Brother KH-120, Bulky 8 and Studio/Singer SK8 and SR-20 ribber sponge bar. Some ribbers were originally sold with a solid plastic bar - we do not supply solid plastic bars as they are no longer manufactured. A regular sponge bar works fine in its place and will be substituted for the original plastic bar. This type of sponge bar is required anyway when knitting lace or using thin yarn such as 2 ply (2/28 or 2/30) as the plastic bar does not work well for lace or thin yarn.

  • It is important not to use craft foam or door/window insulating foam as they do not have a good fabric cover and the sponge deteriorates quickly and can make your knitting machine hard to operate.
