Abstract (en)
[origin: WO2004108395A1] The invention relates to drawing systems using a series of jaws for the support, transport and drawing of the film (2), which are supported and guided by rails and driven by endless chains (3), connecting the jaws between the above. Each chain (3) is driven by two toothed wheels (6, 7) of large diameter (D), one wheel (6) located at the beginning of the forward run (4) and the other wheel (7) located at the rear end of the return run (5) of the chain (3). Each wheel (6, 7) is provided with motorised rotational drive means, said means being synchronised with each other. Such a drive device finds application in high speed drawing machines.
