The Qonvolv DKP001A Waistband (Knit) Buttonholing Attachment is engineered to deliver highly accurate buttonhole positioning on knitted waistbands through advanced interlining handling automation. A pneumatic presser stabilizes the waistband to minimize misalignment, while automatic feeding and retrieving of leftover interlining ensures clean, precise buttonhole formation. A thoughtfully designed positioning guide simplifies operator handling and reduces manual intervention. By eliminating the need for the operator to hold the waistband during the sewing cycle, the DKP001A enables a single sewer to manage two machines simultaneously, greatly improving efficiency and throughput. Paired with the reliable JUKI LBH-1790S lockstitch buttonholing head, the DKP001A achieves consistent, high-speed buttonhole production—ideal for knit waistbands in mass garment manufacturing.
