Thread the extrudate through the tank.
Cut the extrudate off close to the die face and ball up the
end using a soft-metal spatula or scraper. Walk the extru-
date through the system, threading the extrudate through
any calibration or sizing equipment, the water/spray tank
and into the puller.
Move the tank back upstream for normal
operation.
Turn the linear actuator handwheel to move
the tank upstream to within 1 inch of the extruder die face,
or to within 1 to 12 inches of the end of a sizing tank.
Recheck the tank alignment. With the extrudate
threaded, verify that the tank is precisely aligned with the
center of the extrudate.
Position the immersion rollers to prevent the
extrusion from sinking or floating.
Slide each
roller a up or down to the desired position. The best posi-
tion for the rollers depends upon your material, process
and cooling mode.
