Product Subtitle
Programmable Bartacking Machine for Garments, Denim and Workwear
Short Description
The TLK-430FX is an electronic direct-drive lockstitch bar tacker designed for high-speed reinforcement sewing on garments, denim, workwear and multi-layer fabric components. It provides a maximum sewing area of 40 × 30 mm, programmable sewing patterns, digital thread-tension control, automatic thread trimming and pulse-motor-driven material feeding.
Product Overview
TLK-430FX Electronic Direct-Drive Lockstitch Bar Tacker
The TOPEAGLE TLK-430FX is a computer-controlled electronic bar tacking machine designed for reinforcement sewing on garments, denim products, workwear, bags and other sewn products.
Its direct-drive servo system provides responsive starting and stopping while reducing power-transmission loss, vibration and operating noise. With a maximum sewing speed of 3,200 stitches per minute, the machine supports efficient cycle production for pocket openings, belt loops, zipper ends, garment plackets and other high-stress areas.
The pulse-motor-driven X-Y feeding system controls material movement within a maximum sewing area of 40 × 30 mm. Standard bar-tacking patterns can be selected and adjusted according to the required length, width, stitch count and sewing speed.
Digital thread-tension control allows the upper-thread tension to be programmed according to the material and stored with the sewing data. This helps maintain repeatable stitch quality when changing between garment styles or material specifications.
The automatic thread trimmer, thread wiper and programmable work-clamp lift reduce manual handling between sewing cycles. A semi-dry lubrication system helps minimize the risk of oil staining around the needle-bar area, making the machine suitable for clean apparel production.
The TLK-430FX-03 is configured for medium-weight materials, while the TLK-430FX-05 is designed for heavy-weight materials. Customers should select the correct version according to the fabric, number of layers, thread size and reinforcement requirements.
