Advance Operation (cont.)
>> Differential Speed
This feature allows the operator to set the upper and lower rollers to run at a slightly different
speed.
While the upper roller is running at the preset sealing speed, the lower roller is running at a speed
according to the % (percentage) setting.
Lower roller speed = preset sealing speed x % setting
If differential speed setting = 100%, roller is running at the same speed as the upper roller.
If differential speed setting > 100%, roller is running at a faster speed than the upper roller.
If differential speed setting < 100%, roller is running at a slower speed than the upper roller.
The range of percentage setting is 80–150 %.
WARNING !
When using larger differential speed < 90% or > 110%. Always place a piece of fabric
between the nip rollers. Failure to do so may cause excessive stress in the transmission
system which may in turn damage the machine parts
Usage:
To compensate puckering due to stretchiness of fabric
To compensate puckering due to uneven worn out of upper and bottom rollers
To improve a phenomenon called ‘bamboo shell’ on some kind of fabric
Preset sealing speed
