Device for guiding laminar elements for processing, particularly intended for hide and synthetic material folding machines

A device for guiding a laminar element for processing hide and synthetic material folding machines comprising:

• a working element (15) having an active pointed end (15a) engageable by contact with said laminar element (10);
• and
• supporting a drive means (11) for said working element adapted to impart cyclic oscillations to said active end to define a path comprising a raised section (30) raised off of said laminar element and a contact section (31) in contact with said laminar element, said contact section extending along a predetermined feed direction of said laminar element;
• wherein said supporting and drive means comprise:
• a holder, a bar- body extending in a transverse direction to said laminar element being processed and engaging said working element, and a first swivel connection interposed between said bar- body and said holder and defining an oscillation axis of said bar- body substantially parallel to said laminar element;
• said working element is a small rod extending transversely to said laminar element and wherein said active end is one end of said small rod;
• and
• wherein said device has an elastic means (14a) acting on said small rod in a direction toward said laminar element being processed, said elastic means being interposed between said small rod and said supporting and drive means.
