Other uses for the Gauge:
The gauge is exactly 3” long at the longest point. This can be used as a gauge to measure
stitch length.
The gauge is also a good straight edge to check the rotation of the needle chuck. It should be
parallel with the machine. To check, place it on the needle clamping screw. When held
firmly on the screw, it should seek a straight line parallel with the machine. (

3.14 SEWING HEAD SPEED ADJUSTMENT AND
SYNCHRONIZATION WITH THE SYSTEM
3.14.1 CALCULATING CONVEYOR SPEEDS
When calculating speeds for production rates, keep the following in mind:
•
One revolution of the sewing head equals one stitch.
•
The speed of the sewing head needs to be 2% faster than the conveyor that carries the
product to it. This is desired because the sewing head needs to pull the bag taut through
the infeed.
NOTE: The maximum RPM of the Model 100 and 101 sewing heads is 1800
RPM.
•
The speed of the infeed should match the speed of the conveyor.
•
Key information to be gathered:
1) Process speed (number of bags/min)
2) Speed of the conveyor designated to carry bags to the sewing system
3) Desired or required space between bags (often dictated by other equipment such
as weighing and filling)
4) The number of stitches required on the closure
NOTE:
Generally, it has been observed that a slight change in the density of the contents, does not
necessarily affect the production rate.
