Abstract

Ciascuna porzione o goccia di vetro viene separata mediante una coppia (6; 9) di lame di taglio. Le lame di taglio (7, 8; 10, 11) sono disposte su bracci (12, 13) della cesoia, i movimenti dei quali sono sincronizzati tra loro mediante un ingranaggio (16). Un primo braccio di cesoia (12) può essere azionato alla rotazione mediante un comando (36), mentre un secondo braccio di cesoia (13) è sostenuto da una molla pneumatica (28). Una slitta (39), traslabile mediante un cilindro (48, 49) supporta il comando (36). Il comando (36) aziona un perno di manovella (43), che è collegato con il primo braccio di cesoia (12) mediante un'asta di accoppiamento (44). Mediante spostamento della slitta (39) si ottiene una corsa di servizio (34) amplificata rispetto alla corsa di lavoro (32) della cesoia.
