(57) A machine (1) for finishing flexible laminar surfaces (P) used as coating of objects
comprising a load-bearing frame (2) resting on a reference surface (S), a lower transport
and contrast cylinder (3), covered with flexible material and stably coupled to the
load-bearing frame (2), operatively connected with first motorization means (4) which
rotate it around a first transverse axis (X1) defined by the lower cylinder (3), an upper coating cylinder (5), provided with
an engraved outer surface (5a) and stably coupled to the load-bearing frame (2), operatively
connected with second motorization means (6) which rotate it around a second transverse
axis (X2) defined by the upper cylinder (5) which is superiorly facing and opposed to the
lower cylinder (3) from which it is spaced apart to define a passage light (7) that
receives one at a time spread flexible laminar surfaces (P) at least partly supported
by the lower cylinder (3), and a transversal blade (8), coupled to the load-bearing
frame (2), operatively connected with the upper cylinder (5), on the outer surface
(5a) of which it distributes a film of liquid product (L) which the upper cylinder
(5), while rotating around the second transverse axis (X2), deposits by pressure, at the passage light (7), on the upper face (Ps) of the flexible laminar surfaces (P) advancing along a prefixed direction (F) and
supported by the lower transport and contrast cylinder (3). In particular, the ratio
(D1/D2) between the diameter (D1) of the lower cylinder (3) and the diameter (D2) of the upper cylinder (5) has a value comprised between 1.35 and 1.40 (1.35 ≤ D1/D2 ≤ 1.40).
