1 or 2 or 3 needle, double chainstitch sewing machine with bottom feed transport and energy-saving motor with low vibration and noise level. Chainstitch machines are mainly used in sewing operations, where elastic stitch is required, reliable for clothing exposed to strech during use i.e. side leg stitches in trousers.
They are especially recommended for long seams, because the use of chain loopers allows the stitch to be formed directly from thread cone, which eliminates the need to frequent change the bobbins. 2-needle machines are used for production of formal clothing i.e. reinforced seam in men’s trousers or in operations when linen seam is required, and for overlaping.
