ALPHA 4
Alpha 4
FOUR ROLL DOUBLE PINCH
The Alpha 4 brings the lower range of thickness capacity of the plate rolls at COMAL ITALIA. Its largest size has a roll of 7" (180mm)
diameter and the Kappa 4 model starts at 8.500" (220mm) diameter. It has been designed to specifically cater to the shops
which roll thinner materials. The Alpha 4 has the top and the pinching roll powered in rotation, whereas the Kappa 4 has the
top roll and the bending rolls powered in rotation, because the thicker material with higher bending forces contribute more
to the friction component of the force used in pushing the plate through the rolls as compared to the friction force supplied
by the thin material being formed on Alpha machines.
