024 Rollforming problems!
Checklist: - Set the roll clearance to 30-50% of the sheet thickness. => refer to the manual. - Do you have red springs in use for the upper front roll? => reduce the spring tension and check the spring color. - Spring pressure too low: => Tension the red/black springs with 3 - 3.5 revolutions. => Check the roll clearance with a dial indicator. - Rollformer motor too weak? => Provide us with the nameplate and a photo of the motor. - Change the frequency inverter of the rollformer motor to 87Hz technique. => This is the new standard of the CM X8. - Do you have a two-piece catching plate around the lower welding arm (Rollformer 420/540)? => This helps to guide overrounded canbodies back into the Z-rail. - Have you mounted a inner mandrel in the canal (Rollformer 420/540)? => This also helps to guide overrounded canbodies back into the Z-rail. - Catching canal: Is the interior measurement of the two shells corresponding to each other? => If the interior diameter is too big, too open-rounded canbodies might not be correctly conducted into the canal. - Catching canal: Does the canal flap works properly? => The flap might even touch the canbody, which is being welded. Only the a perfect adjusted flap fulfills their purpose. - Check the upper rollformer plate: Use a dial indicator to see, if there are back and forth or up and down movements.
