KANSAI SPECIAL NR-9803GP 3-Needle 5-Thread 1/4" Gauge Cylinder Bed Coverstitch Industrial Sewing Machine with Puller for Elastic Attaching on Knitwear - Complete Setup, Table, Stand Included

The KANSAI SPECIAL NR-9803GP is a 3-needle 5-thread cylinder bed coverstitch industrial sewing machine engineered specifically for elastic attaching on tubular knitwear — waistbands, leg openings, athletic-wear leg cuffs, underwear, leggings, briefs, and any circular elastic-band insertion operation where a flat-bed machine cannot reach. Configured at 1/4" (6.4 mm) needle gauge with an integrated puller, the NR-9803GP delivers simultaneous top and bottom coverstitch covering on light to medium knit fabrics. Kansai Special invented the modern coverstitch class and the NR-9800 series remains the global benchmark for cylinder-bed elastic attaching. The narrow cylinder bed lets operators sew tight tubular pieces — child-size waistbands, narrow leg cuffs, athletic-wear underwear — that cannot fit on a flat-bed coverstitch. The integrated puller actively advances the tube at the same rate the feed dog moves the fabric underneath, eliminating drag, stretch, and uneven stitch spacing as the elastic is stitched into the seam. This configuration ships with the Speedway 550W brushless servo motor mounted to a complete industrial table and stand, delivering smooth variable speed control up to 4,800 sti/min with low noise, low energy consumption, and instant-stop response. The wide differential feed ratio of 0.3 – 2.9 covers virtually any elastic-attaching tension requirement, from light fabric ease through aggressive elastic stretching.
