MACHINE FOR FINISHING FLEXIBLE LAMINAR SURFACES USED AS COATING OF OBJECTS

摘要

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 (P_s) 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).
