Definitions

  • the subject of the present invention is a mechanical device for recording image distortions which occur in color printing on stamped metal cans and for drawing the corresponding correction curves.
  • the present invention has completely solved this problem since the distortions which the image undergoes during stamping are noted by the same apparatus which will be used to draw the correction curves and to modify the originals.
  • the new invention is characterized by a flexibility of application which makes it possible to continuously adapt to materials of different characteristics, a simplicity of implementation which does not require the intervention of a specialist, a great speed of execution. as well as extreme reliability and precision.
  • the apparatus which is the subject of the present invention consists of two coplanar frames, one inside and the other outside, the latter being open on a side perpendicular to the direction of movement, the two frames being guided by slides. parallel.
  • the interior frame carries a frosted or opalescent window lit from below by a light source.
  • a transparent glass or plastic plate or a film integral with the structure of the device are fixed to the frosted glass.
  • This plate or film bears engraved, perpendicular to the direction of movement, a thin reference line.
  • the inner frame can be moved by hand in either direction.
  • the outer frame located in the same plane as the inner frame, has an open side and therefore, seen in plan, it has a U-shape. This outer frame moves in the same direction as the inner frame from which it borrows movement.
  • the movement of the external chassis is regulated by a bar or rod articulated at one of its ends on the frame of the device.
  • This bar can therefore take various inclinations with respect to the slides which guide the chassis.
  • On this orientable bar is mounted a slide which, by means of an articulated joint, can be made integral with another slide mounted on a rod perpendicular to the direction of movement and integral with the interior frame.
  • the inner chassis carries, at its lower part, at its four corners, four idler pulleys mounted idly on ball bearings. On these same pulleys passes a steel belt tensioned by a ten ad hoc. With a clamp, it is possible to link the aforesaid belt to the slide mounted on the orthogonal axis and by means of another clamp, one can also link this belt to the external frame. In this way, a kinematic system has been produced such that by moving the inner chassis in one direction, the outer chassis will follow it in the same direction.
  • the displacement of the external chassis will always be equal to that of the internal chassis; there will therefore be no relative displacement of one of the chassis relative to the other, while increasing the angle of inclination of the articulated bar, there will be an increasingly greater relative displacement.
  • a support is mounted to which it is possible to fix a pencil or a ball or fiber marker.
  • the concentric circles at unit distance drawn on the flat sheet will have undergone all the deformations which, by the survey, can be transformed into a deformation curve.
  • the cut box sector is fixed above the polyester film which is integral with the interior frame with the line corresponding to the diameter of the bottom of the box in perfect coincidence with the reference line.
  • the articulated bar will have taken a determined inclination and in this displacement, the style will have traced the first coordinate.
  • the reference letter (A) designates the interior frame
  • the letter (B) the corresponding frosted glass which is lit from below
  • the letter (C) indicates the reference line drawn on the transparent plate marked with the letter (D).
  • the letter (E) indicates the external frame
  • the letter (F) indicates the hinged bar at point (G) of the fixed structure, bar to which one can give, by maneuvering by hand, various inclinations which have the effect of varying the relative displacements of the outer chassis relative to the inner chassis
  • the letter (H) indicates the slides which guide the longitudinal displacements.
  • Fig. 1b shows the kinematic system which ensures the relative movement of the two chassis relative to each other and the device with two slides which actuates and adjusts this relative movement as a function of the inclination given to the articulated bar.
  • the letter (K) designates the orthogonal bar on which the slide (I) moves, linked to the slide (L) which slides on the tilting bar (F).
  • the letter (M) designates the style clip which is integral with the slide (L).
  • the letter (N) designates the kinematic transmission belt stretched over the four pulleys (O).
  • the letter (P) designates the clamp that secures the belt (N) with the outer frame (E).
  • the letter (E) designates the outer frame
  • the letter (A) the inner frame the letter (C) the reference line
  • the letter (S) designates the already stamped box sector which is fixed on the inner frame
  • the letter (T) designates the transparent millimeter film which is fixed to the outer frame.
  • the letter (V) indicates the plot style and the letter (Z) the small sheet of drawing paper.
  • the present invention may obviously also take in its practical embodiment a form different from that which has been illustrated above, but all fall within the same principle of the invention.
  • We can, in particular, change the respective positions of the chassis and the rear bar. ticulate, as well as the kinematic transmission system; in addition, all the details of the construction may be replaced by equivalent elements as they may appear obvious to a specialist in this field, without departing from the protective framework of the present invention.
