HL-1790S Computerized Direct Drive Flat Head Button Hole Sewing Machine
1. This model is used for button holing of all kind of materials, especially for sleeve button holing. Unique electronic yarn clamping mechanism, through the adjustment with the electromagnet yarn clamping tension can achieve the difference needs of button holing middle parallel part and bar tacks tension.
2. The cutting force of up-and down movement is drived by the both way electromagnet to make the cutting material more accurate. Through the unique function of slicer repeatedly fall and rise, do not need to change the slicer when change the size.
3. Multifunction of operation panel can setting the front five needle through the operation panel,to achieve the function of slow start, effectively avoid the break Line when machine fast start. Through the electronic control to bar tacking the last sewing to avoid the off- line of buttonhole. The adjustments of width, length of buttonhole, the speed of sewing can achieve through the operation panel.
4. Use 5 high precision stepper motor (top tangent, down tangent, feed, swing presser foot),capacity of decomposition can reach 0.05mm,make the stitch more steady and beautiful. Meanwhile easy achieve auto-operate, Greatly simplify the organization and reduce the noise.
5. Use the electronic control take place of tradition button holing depend on the master cam to change the sewing style, to make the shape of sewing changeable And size more convenience, short time of adjustment and high work efficiency.
6. Through the technology of dry machine head, do not need oiling except the rotating shuttle parts, eliminating the material pollution by the machine oil, solve the ubiquitous problem of run up oil leak and oil splashes. Use the cop latch clamp equipment, can effective avoid the cop latch idle when the machine stop.
7. Expansion of the table- board of presser foot, the reduce of wide in width of tool needle drop point in left, have more advantage of the place of material, increase the operation. Top and under thread use the new trapper, when starting sewing make sure the top and under thread lead correct, guarantee substance and beautiful.
