  • Patent number: 7182007
    Abstract: A substrate to be cut and/or scored is pre-printed with graphics, at least first and second registration marks, and optional encoded-to-print instructions, bar-encoded data, as well as ordinary graphics. The registration marks are sensed as the substrate is automatically transported to a cutting table station that defines a cutting reference plane. Sensed detection of location of the registration marks relative to the reference plane enable the cutting plan for the substrate to be amended for precise location of the graphics on the substrate relative to the reference plane. Automated cutting according to the amended cutting plan occurs. As the registration marks were printed simultaneously with and in known relationship to the graphics, the cut line will be precise relative to the graphics. Machine readable encoded-to-print instructions optionally printed on the substrate can further amend the cutting plan.

    Abstract: A device for trimming and automatically cutting of either multiple or single images, the images produced for example through digital rendering on paper and other graphic and photographic substrates, wound in reel or being in single sheets (10), especially of large size. Problems in using known devices of this type with feeding rollers (2) with a length corresponding to the substrate width have the consequence of a slowing down of the production owing to the excessive care necessary when introducing at the same time parallel sheets of large size. These problems can be overcome by using rollers of reduced length, but only by adding errors in the forward movement of the substrate, errors which are remedied by of optical sensors (4, 4?) for detecting the separation mark (M) between the images (10a, 10b, . . . ) as well as its angle with respect to the cutting line (7), and by a pair of length differential measuring devices (6).

  • Patent number: 6619167
    Abstract: An improved method and apparatus for cutting a graphics area from a sheet of material which includes such graphics area. The method improved involves applying a plurality of registration marks on the sheet at and about the graphics area in predetermined positions at the time the graphics are applied thereto, the plurality of marks including a subset of marks (the subset preferably being a tandem pair of marks) which is applied on one side of the graphics area which are used to determine the position and orientation of the sheet, sensing the locations of the registration marks on the sheet of material at the time of cutting, and cutting the graphics area from the ready-to-cut sheet along a path determined in response to the sensed positions of the registration marks with respect to the graphics area at that time, whereby precise cutting occurs despite two-dimensional distortion of the sheet prior to cutting.

  • Patent number: 6619168
    Abstract: An improved method and apparatus for automatic cutting of graphics area(s) from a sheet of material which includes such graphics area(s), the graphics areas having a plurality of registration marks in predetermined positions with respect thereto and including a subset of the marks on no more than one side of the graphics area which are initial-position/orientation-determining marks. The method involves placing the sheet on a sheet-receiving surface, attempting to sense the subset in the field of view of a main sensor, and, when the subset is not in an expected location, automatically determining the coordinate region of the subset on the sheet-receiving surface and automatically repositioning the main sensor to the coordinate region such that the subset is within the field of view of the main sensor.
