Higher productivity: The machine runs at 3,000rpm,faster than any other sewing machine ever made. In addition to the high-speed sewing performance. the machine’s starting, stopping. thread .trimming and automatic presser lifting speeds have been increased to significantly shorten total cycle time (reduced approximately 30% compared to our predecessor model: for 42-stitch large bar tacks). Excellent seam quality: The machine comes with a newly developed needle thread grasping mechanism. The mechanism prevents thread from slipping off from the needle eyelet at the beginning of sewing. from tangling on the wrong side of the material and also being stained during sewing. The thread trimming mechanism has been further improved to shorten the length of thread remaining on the wrong side of the material after thread trimming. C. Wider sewing area and many different sewing patterns: With its 30mm (length) by 40mm (width) sewing area.t he machine can sew many different shapes of bartacks.The machine is provided as standard with as many as 50 different types of sewing patterns including semilunar bar tacking, round bar tacking. radial tacking as well as conventional barucks. Oil stains are eliminated: Thanks to our advanced dry-head technology, the frame (needle bar and thread take-up) no longer requires lubrication. This prevents the material from being stained with lubricating oil. Just a small quanta), of lust clean oil is supplied from the oil tank to the hook.
