ABSTRACT:
The invention relates to a device for guiding laminar elements for processing, particularly intended for hide and synthetic material folding machines, which comprises a working element (15) having an active end (15a) engageable by contact with a laminar element (10) being processed, and supporting and drive means (11) for the working element (15) adapted to impart cyclic oscillations to the active end (15a) defining a path comprising a section (30) raised off the laminar element (10) and a section (31) of contact with that same laminar element (10), the contact section (31) extending along a predetermined feed direction of the laminar element (10).
