LBH-1790ANS

Electronic lockstitch buttonhole machine with direct motor and control keyboard with 'Usb' port for inserting customized buttonholes. The foot is operated with a step-by-step motor to ensure adequate pressure in relation to the different materials, and is complete with thread trimmer with lower and upper earwig. The buttonhole 'multiple cut' system is driven by a motor which avoids having to change the knife if the buttonhole size changes. The needle thread tension is set digitally and adjusted by a magnet.
