Question: Which machine series are described as ideal for producing seamless warp-knitted goods with little make-up required?
Answer: The RDPJ and DJ machine series, specifically two-bar raschel machines for seamless production.
Card 7
Question: What garment features can two-bar raschel warp-knitting machines produce?
Answer: Tubular shapes with variable diameters, functional zones in specific locations with different stretch values, seams worked into the garment, open-work
Card 8
