Speed control

Schiffli machine frames are heavy. Longer stitches and hence large frame movements need more time. Changes from needles to borers also need time. Speed in Schiffli machines, like tension, is controllable from within ES Schiffli. Special functions – ‘Fast’ and ‘Slow’ – are provided and the necessary codes added to the output file.

Normal operating speed in Schiffli machines is ‘Fast’. This generally translates as follows:

Saurer 1S/2S: 105–125 RPM (Revolutions Per Minute).

Hiraoka 15 yard: 135–145 RPM.

Some machines use further fine speed adjustment like Saurer ±5 RPM increments. ES Schiffli supports these.
