Knitting Machine Sponge Bar. Commonly called needle retainer or compression bar. This item supplies back up pressure for needles to hold them in place while allowing needle movement. They eventually lose their elasticity and strength as the foam rubber decomposes and collapses. They should be examined and replaced whenever the foam rubber loses 1/2 its original heigth (typically 2-3 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.
Also available is a sponge bar repair kit. Kits are intended 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. The rebuild kit includes both the glue and sponge (plus 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 have a special long lasting foam that has a fabric covering to make it last. If your machine is not listed, please contact us as it was probably just an error of omission.
-
Unfortunately, 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 - these are no longer manufactured. Also, some ribbers were originally sold with a solid plastic bar that was intended to be replaced with a true sponge bar by the selling dealer - we can not supply solid plastic bars as they are no longer manufactured, however a true sponge bar can be used in place of the plastic bar.
-
Some sponge bars can be rebuilt by purchasing a "sponge only" (listed below) and by cutting them to size and gluing them in place.
-
It is important not to use craft foam or door/window insulating foam as they do not have a good fabric cover and can deteriorate quickly or make your knitting machine hard to operate.
This item cannot be shipped outside the USA due to postal restrictions on export shipments.
