1 2-needle, eedle-feed, ockstitch achine (with automatic thread trimmer) The tension applied to the bobbin thread has been reduced and the needle thread path has been thoroughly renovated to achieve highly consistent feed of the needle thread. uckering, stitch skipping, thread breakage and isolated idling loops can be therefore prevented, enabling the machine to produce beautifully finished seams with consistency. fter the gauge has been replaced, the machine can be adapted to the newly installed gauge only by adjusting the clearance provided between the blade point of the hook and the needle. In this case, it is not necessary to change the hook timing in accordance with the gauge. s a result, the length of time required to replace the gauge is dramatically reduced / needle, eedle-feed, ockstitch achine with Organized plit eedle ar (with automatic thread trimmer) The organized split needle bars which enable either the left or right needle to stop independently of the other can be changed over by simply operating the lever, thereby saving labor in corner stitching. 2-needle, eedle-feed, ockstitch achine with arge ooks (with automatic thread trimmer) Our investigation of the thread take-up stroke and other mechanisms results in the reduction of irregular stitches. ven at high speed, the machine performs sewing as consistently as the standard hook machine. The machine can make the most out of the advantageous features of the large hook, upgrading the finished quality of heavy-weight materials and improving efficiency. 2-needle, eedle-feed, ockstitch achine with Organized plit eedle ar and arge ooks (with automatic thread trimmer) The organized split needle bar mechanism makes it possible to stop or reset the left or right needle by operating a one-touch utility lever. The machine produces neatly finished stitches at corner parts of the material. Improved thread tension and presser foot dramatically upgrades the seam adjusting ability. The range of thread counts that can be used is widened / needle, ottom-feed, ockstitch achine The machine has adopted a bottom-feed mechanism. This enables the machine to perform sewing with a low tension applied to the material while preventing puckering and stitch skipping, thereby improving consistency of seam quality. The machine is capable of adapting to the sewing of light-weight materials and newly-developed materials. This means that the machine is exceedingly effective to the process to sew top center plaits of shirts and the sewing of foundation , , 3168, , 3178, , 3188, , 3120 (eptember, 2003) 1/12
