Interactive system for projection of images on materials with synchronization between the image projected and the position of the work area, achieved by means of the joint operation, controlled by computer 1, of a system for traction of distended materials held at their ends on a conveyor belt 2 that has movements in both directions, a system for projecting images that consists of a video projector 3 and an image-synchronization system. Overall, the present invention guarantees a high level of rigor and image resolution at any point of the defined working area, allowing its use in the positioning and fitting of pieces to be cut, scored or punched on materials and to by-pass defects, optimizing levels of waste, being designed especially for use as a supplement to the automatic digital-control system for cutting, scoring and punching hides and other materials for the footwear, component and similar industries.
