DEVICE FOR MANUFACTURING OF BELT WITH CORRUGATIONS ARRANGED IN STAGGERED ORDER Russian patent published in 2009 - IPC B21D13/02 

FIELD: technological processes.

SUBSTANCE: invention is related to the field of metal plastic working, in particular to accessories for corrugation of belt material. Device comprises the following components installed on the common base and connected to drive - reciprocal mechanism for belt feed with feeding frame, joined to mechanism of corrugation rib pitch control, stamping corrugating unit with matrices in the form of plates and puncheons in the form of combs, joined with mechanism of corrugation height control and mechanisms of its reciprocal motion in plane, which is perpendicular both to direction of initial belt motion and to direction of stamping unit motion along columns. Besides every matrix is made of two adjacent parts with section of every part in the form of angle bar shelf with alternating section and certain thickness. Adjacent matrices in every plate are installed as oppositely mirror-like and are joined with rivets with certain gap and pitch of rivets location. On the common base upstream and downstream the belt feed control mechanism, two identical mechanism units are installed, every of which consists of mechanisms of controlled fixed installation of belt installed one after another depending on belt width and controlled reciprocal motion of controlled fixed installation in direction perpendicular to direction of belts motion. Between mentioned units mechanism is installed for permanent belt braking.

EFFECT: increased resistance of matrices and quality of corrugated belts.
