Additional Machine Details:

Die creasing and perforating machine PETRATTO CORDOBA 3 BA+F of 2011, with folds for high grammage and optional gluing unit (gluing heads not supplied) Cross Knife Creasing and Buckle Folding Machine for the production of enhanced quality covers (for saddle stitching and perfect binding) folders and leaflets, with flaps folded and products difficult to bend as flap folders or wallets products. The integrated creasing system provides a superior finish quality and this even in the bad sense of casting paper. Creasing knife eliminates the problem of cracking especially on products with high weight products or surfaced paper / cardboard (varnish, film ...). The knife has a consistency in creasing and provides the highest quality without damaging the material. Quick Sets can produce profitably especially with small and medium runs. Mode of operation : Sheets are introduced by a pile feeder in to the angled-belt infeed, aligned and passed to the creasing station. A photo-detector registers the front edge of the product and the computer controlled drive moves the product to each of the cross-creasing positions set on the control panel. Then the product is passed into a special buckle folding unit where it is folded accurately on the crease lines. Size change is very quick, many settings being done via a keypad or digital readouts.
