Patent attributes
A warp knitting system may knit a seamless tube of fabric. The fabric may have a spacer between outer and inner fabric layers. The knitting system may have first and second needle guide systems. The first and second needle guide systems may each have selectively linked needle bed sections that guide respective needles. A guide bar system may have guide bars that dispense strands of material during knitting. Each guide bar may be positioned using a respective guide bar positioner. The guide bar system may be shifted relative to the needles using a rotational positioner. The needle guide systems and guide bar system may be formed from selectively coupled links. The selectively coupled links may be configured to adjust the diameter of the tube of fabric to a desired value. The thickness of the tube may be adjusted by adjusting a gap between the first and second needle guide systems.
