Abstract
An apparatus for imparting a relief effect to patterns on even surfaces. A cylinder is formed by winding upon itself a thick metal sheet which is provided with holes therethrough. A doctor permits the depositing of a coat of a colorless varnish onto the surface to be coated when the surface is translated linearly relative to the rotatable cylinder.
Claims12
An apparatus for imparting relief to a pattern on a surface, comprising, in combination:
- a first cylinder, containing a doctor therein, for selectively depositing on said surface a first predetermined pattern of a first flowable material having a first color;
- a second cylinder, containing a doctor therein, for selectively depositing a second predetermined pattern, which is different than said first predetermined pattern, of a second flowable material having a second color which is different than said first color;
- a third cylinder, containing a doctor therein, for selectively depositing a third predetermined pattern, which is different than said first predetermined pattern, of a flowable material having a third color which is different than said first color;
- and
- a fourth cylinder, containing a doctor therein, for selectively depositing a fourth predetermined pattern, which is different than said first predetermined pattern, of a substantially thick layer of said flowable material on only those preselected portions of said patterns which are to be raised.
2 more elements
An apparatus for imparting relief to patterns on a surface, comprising:
- at least one printing cylinder for depositing on said surface predetermined patterns;
- said cylinder selectively printing a flowable material with a predetermined color;
- at least one special cylinder for selectively depositing a substantial thick layer of product on only preselected areas of said printed surface;
- and
- said special cylinder comprising a sheet metal provided with holes and a doctor for depositing a flowable material product which passes through the holes and coats the areas which are to be raised, the relief effect being obtained by the great thickness of said layer which can reach at least 0.5 millimeters.
