Machine for stretching films, comprising two tracks each having a first rail () on which clips () move and close together at a point for adjusting their pitch and a second rail () on which articulated carriages () move, in a chain driven by a toothed drive wheel (), with two consecutive clips () respectively, characterised by a wheel () for indexing the point for adjusting the pitch of the clips ().

Machine for stretching films or sheets

The invention relates to drawing systems using a series of jaws for the support, transport and drawing of the film (), which are supported and guided by rails and driven by endless chains (), connecting the jaws between the above. Each chain () is driven by two toothed wheels () of large diameter (D), one wheel () located at the beginning of the forward run () and the other wheel () located at the rear end of the return run () of the chain (). Each wheel () 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.
