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.

Key Features

• 3-needle 5-thread top & bottom coverstitch (ISO 602 + ISO 605) — simultaneous top covering on the face of the fabric and bottom chainstitch on the underside
• Engineered for elastic attaching — the primary application of the NR-9803 platform, optimized thread path and feed geometry for elastic insertion on tubular pieces
• Cylinder bed construction — sews tubular pieces a flat-bed coverstitch cannot reach: waistbands, leg openings, narrow cuffs
• Integrated puller attachment — actively pulls the tube at feed-dog rate, preventing slip, drag, and uneven stitch spacing across the elastic seam
• 1/4" (6.4 mm) needle gauge — industry-standard spacing for elastic attaching and knitwear coverstitch
• 4,800 sti/min max sewing speed — high-throughput tubular production
• Wide differential feed ratio 0.3 – 2.9 — covers light fabric ease through aggressive elastic stretching in a single machine
• Speedway 550W brushless servo motor — quieter, lower energy use, instant-stop response vs clutch motors
• UY128GAS needle system — Kansai-standard coverstitch needle, widely available across suppliers
