MACHINE DESCRIPTION AND USE:
The machine consists of a sturdy steel sheet structure painted with epoxy powder. The parts involved in micro-
rolling and smoothing the dough are protected by a belt in the fixed upper part of the machine and in the mobile
lower part.
The lever with lifting knob on the left allows nearing the plates to each other, while the lever with the red knob is
used - with movement from right to left - to modify the planarity of the lower plate support surface.
There is an appropriately graduated adjustment handle on the right side of the mobile part, to adjust the distance
the two plates must maintain during processing, i.e. the final thickness of the dough.
Numbering is purely indicative and does not refer to cm or mm.
