● JUKI Juki Computer Sewing Machine f550-J ● ■ Adopts the [BOX feed] technology of industrial sewing machines. Unlike conventional feed mechanisms, it reconsiders the balance of the core sewing components: the hook, thread take-up lever, needle bar, and feed dog. By keeping the feed dog horizontal while feeding the fabric, it effectively addresses issues like fabric shrinkage and slippage. It also provides a comfortable sewing experience, such as straight stitching and starting to sew. ★ Automatic thread threading ★ Automatic thread tension ★ Automatic thread trimming ★ Presser foot pressure adjustment ★ Needle up/down button ★ Needle stop position: Down ★ Needle stop position switching ★ Lock mode - ★ Elongation ★ Memory function: Up to 10 ★ Lights: LED/2 locations ★ Hook type: Horizontal rotary hook ★ Free arm ★ Cord reel ★ Quick bobbin winding (independent bobbin winding motor) ★ Bobbin thread detection - ★ Stitch length: Dial type, numerical LCD display, maximum: 5mm ★ Stitch width: Dial type, numerical LCD display, maximum: 7mm ★ Number of needle positions: Straight stitch: 37, Other than straight stitch: 3 ★ Pattern mirroring: Left and right ★ Backlit LCD panel ◆ Number of sewing patterns: 225 (10 direct patterns, 23 practical patterns, 15 buttonhole patterns, 67 quilt patterns, 72 decorative patterns, 38 one-point patterns) Other hiragana, katakana ◆ Kanji 1 font, vertical and horizontal writing, numbers, alphabet 2 fonts ◆ Buttonhole sewing: Automatic, sensor method, with fixed plate, knife width adjustment function, buttonhole length: 0.7 ~ 3.2cm ◆ External dimensions (width x height x depth mm): 445 x 291 x 210 (Dimensions with case set: 510 x 305 x 257) ◆ Weight (kg): 9.8 kg ◆ Sewing speed: 900 stitches/minute ◎ This is a used item, so please refrain from purchasing if you are sensitive to such things!!! ◎ Internal and external cleaning, disassembly cleaning/maintenance/overhaul, and oiling have been completed. ◎ Thorough test sewing has been performed, so you can use it comfortably! ◎ The operation is very smooth and it sews beautifully ⇒ The sewing sample was created with this sewing machine! ◎ Accessories are as shown in the images!
