ABSTRACT:
A bending machine for forming offset printing plates and conversion components for converting older model plate benders into bending machines capable of forming reverse bend plates. The plate bender includes a table support for the plate to be bent. The table is provided with edges having contours identical to the desired contours of the edges of the plate after bending. At least one of the end edges is provided with a die having a reverse bend component formed in it. The bend on one end of the plate may be formed in a conventional manner, while the reverse end bend of the plate is formed in a two-bend sequence by suitable structural components which in themselves may form a conversion system for older plate benders.
