AKYAPAK-AHS-UserManual-2019.03.11
The narrowest diameter of the oval cylinder is brought to the lowest position of the upper
roll. Both side rolls are raised until they contact cylinder so that they will be at the same
position. Then, side rolls are raised a little more, and pushed with a light force to provide a
pear form to the cylinder.
Bring the lower roll to the lowest position. Bring the calibration switch to calibration
position. Therefore, rotation of the lower roll shall be cancelled and rotating power shall be
transferred to the upper shaft only.
Rotate the cylinder by pressing the rotation button. You shall always rotate it in the same
direction. Lower the side rolls gradually at each rotation. Desired circularity shall be achieved
when the contact of the side rolls with the cylinder is lost.
CAUTION
Max calibration capacity is 75% of max thickness.
PREPARING THE MACHINE TO CONICAL BENDING
Prepare the machine to operation with the following procedure before placing the plate on
the machine:
1) Ensure that the material is compressed with the support of cone by leaning the higher
part of the ROLL in the center.
2) You can bend the cone correctly by leaning the side rolls. Then, a conical form may be
obtained with the maximum slant.
PLACING THE MATERIAL
The mouth part of the material, which is smaller, shall always be on the control unit side and
shall always be leaned on the cone support.
