GC20618-2
| This is the two needle compound feed version of the GC20618 series. An automatically lubricated machine - it uses two large vertical axis rotating hooks and a sliding bar thread take up to form crisp stitches. Needle bearings for the arm shaft and hook shaft together with the drive belt and plunger pump mechanism help to create smooth and quiet operation. A safety clutch is standard to help prevent hook damage. It is used extensively in the manufacture of car seat cushions, safety belts, air bags, tents and parachutes. Choose undertrimming model GC20618-2-D if you require added functions and increased productivity. |
