SHEET-FED STAMPING PRESS HAVING A FOIL LAMINATING UNIT

There is described a sheet-fed stamping press (10*) comprising a foil application unit (2*) designed to allow transfer or lamination of foil material onto successive sheets (S), which foil material is fed to the foil application unit (2*) in the form of a foil carrier (FC) supplied by means of a foil feeding system (3). The foil application unit (2*) comprises a stamping cylinder (21 ) with at least one circumferential stamping section (210) provided on a circumference of the stamping cylinder (21 ) and comprising successive stamping segments (211 *; 211 **) distributed one after the other about the circumference of the stamping cylinder (21 ), the stamping cylinder (21 ) also acting as sheet-transporting cylinder and comprising multiple sheet holding units (21 a) distributed about the circumference of the stamping cylinder (21 ) and designed to hold successive sheets (S) against the circumference of the stamping cylinder (21 ). The foil application unit (2*) further comprises a plurality of counter-pressure units (25) distributed about a portion of the circumference of the stamping cylinder (21 ) and designed to press the successive sheets (S) and the foil carrier (FC) against an outer surface of the stamping segments (211 *; 211 **), the foil carrier (FC) being supplied by the foil feeding system (3) between the sheets (S) and the stamping segments (211 *; 211 **). Each counter-pressure unit (25) is designed as a cylinder unit (250, 255) provided with at least one circumferential pressing element (255) positioned to cooperate with the circumferential stamping section (210) of the stamping cylinder (21 ), and a ratio (D21/D25) of a nominal diameter (D21 ) of each circumferential stamping section (210) of the stamping cylinder (21 ) over a nominal diameter (D25) of each ring element (255) of the counter-pressure units (25) is an integer multiple. L'invention concerne une presse à gaufrer d'acheminement de feuille (10*) comprenant une unité d'application de feuille (2*) conçue pour permettre un transfert ou une stratification de matériau de feuille sur des feuilles successives (S), ledit matériau de feuille est acheminé vers l'unité d'application de feuille (2*) sous la forme d'un support de feuille (FC) fourni au moyen d'un système d'acheminement de feuille (3). L'unité d'application de feuille (2*) comprend un cylindre de gaufrage (21) ayant au moins une section de gaufrage circonférentielle (210) disposée sur une circonférence du cylindre de gaufrage (21
