About the 1560N
The 1560N sews two rows at once with unison feed, which is how a trim shop sews French seams, double topstitch on bolsters and parallel rows on awnings and boat cushions. Each needle has its own vertical-axis large hook, so both rows lock the same way and bobbin changes are rare. The stitch goes to 8mm, the foot lifts 5/8 inch by knee, and the climbing device keeps the stitch even over a seam crossing.
It runs 46 to 138 thread through 135x17 needles at up to 2,000 RPM, with needle gauges from 3/16 to 1/2 inch available. A split needle bar for turning corners is an option.
