A powered upper transport works together with the lower feed dog, so both layers of fabric advance at the same rate instead of the top layer creeping backward against the bottom one. An \u003cstrong\u003eadjustment gear sets the differential ratio between the upper and lower feed\u003c\/strong\u003e, which means slippery knits, stretch panels, and mismatched-length seams stay aligned from the first stitch to the last — no operator stretching, no re-cutting the seam.\u003c\/p\u003e\n\u003cp\u003eBeyond the feeding system, this is a \u003cstrong\u003efull-function automatic machine\u003c\/strong\u003e: photocells drive an electronic chain cutter and an electronic presser foot lifter, and the operator can run it in \u003cstrong\u003ethree modes\u003c\/strong\u003e — fully manual on the pedal, semi-automatic where the pedal sews while the machine trims and lifts on its own, or fully automatic where the photocells run the entire cycle. Set up for \u003cstrong\u003emedium and light knitwear\u003c\/strong\u003e with DC×27 #11 needles and a 4 mm overedge, it runs at \u003cstrong\u003e6,000 SPM\u003c\/strong\u003e on a direct drive
