(57) In hide processing machines provided with cylinders with blades as, for example,
fleshing machines, trimming machines, holding machines or the like, which present
a wide opening port, a device is provided, which automatically positions the protecting
shield (12) for the cylinder with blades (2) at the opening of the opposing roller
(3) for the inserting of a hide and which moves the protecting shield (12) away from
the cutting area at the closing of the opposing roller (3) itself.
The positioning is obtained by mechanical means, at a speed which is synchronized
with the approaching or moving away speed of the opposing roller (3).
The purpose is that one to prevent accidental contacts of the hands of the operator
with the rotating cylinder with blades (2).
