The cylindrical arm lets a tubular seam pass around the machine instead of under a flat bed, so sleeves, side seams, and inseams close flat without puckering. Three needles lay six threads in one pass, which produces the strong folded French seam that denim and workwear are inspected on. A top and bottom roller-type steel cloth puller clamps the material and feeds it evenly, so heavy layers do not drift out of line across a long seam. UAE and GCC workshops making jeans, coveralls, and uniform trousers use it where seam strength decides whether the garment passes.\u003c\/p\u003e\n\u003cp\u003eThe looper tucks the thread reliably, which prevents skipped stitches on thick material and cuts the rework that follows them. Stitch length is set by push button rather than by hand adjustment, so an operator changing between fabric weights makes the change in seconds and repeats it exactly on the next machine.\u003c\/p\u003e\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eThree needles and six threads form a double chainstitch French seam in a single pass\u003c\/li\u003e\n\u003cli\u003eFeed-off-the-arm cylindrical bed closes sleeves, side seams, and inseams without puckering\u003c\/li\u003e\n\u003cli\u003eTop and bottom roller-type steel cloth puller clamps heavy material and feeds it evenly\u003c\/li\u003e\n\u003cli\u003eLooper tucks the thread reliably, preventing skipped stitches on heavyweight fabric\u003c\/li\u003e\n\u003cli\u003eDirect-drive energy-saving servo motor\u003c\/li\u003e\n\u003cli\u003ePush-button stitch length adjustment for fast, repeatable changes between fabric weights\u003c\/li\u003e\n\u003cli\u003eSupplied with a folder developed for this machine, for consistent seam folding\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eSpec\u003c\/th\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStitch type\u003c\/td\u003e\n\u003ctd\u003eDouble chainstitch, feed-off-the-arm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNeedles \/ threads\u003c\/td\u003e\n\u003ctd\u003e3 needles, 6 threads\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNeedle system\u003c\/td\u003e\n\u003ctd\u003eTVx5 21#\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNeedle gauge\u003c\/td\u003e\n\u003ctd\u003e1\/8 in (3.2 mm) on the JK-T9280D-73 configuration\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMax sewing speed\u003c\/td\u003e\n\u003ctd\u003e3,000 s.p.m\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePresser foot lift\u003c\/td\u003e\n\u003ctd\u003e10 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMotor\u003c\/td\u003e\n\u003ctd\u003eDirect-drive energy-saving servo\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePackage dimensions\u003c\/td\u003e\n\u003ctd\u003e685 x 535 x 475 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNet \/ gross weight\u003c\/td\u003e\n\u003ctd\u003e61.5 \/ 68.5 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eApplications\u003c\/td\u003e\n\u003ctd\u003eHeavyweight denim, workwear, and uniform side seams, sleeves, and inseams\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"Jack","offers":[{"title":"Default Title","offer_id":52186462683432,"sku":null,"price":0.0,"currency_code":"AED","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0947\/2203\/1912\/files\/jack9280.jpg?v=1785753419","url":"https:\/\/alborj.com\/products\/jack-jk-9280d","provider":"Al Borj Machinery","version":"1.0","type":"link"}
