  • Patent number: 6843474
    Abstract: The present invention relates to a method of and an apparatus for separation and application of thin objects of a non-porous material or of a material of low porosity on a surface. The invention also relates to a package for the thin objects. With the aid of a pick up and lay down head on an application means a vacuum is applied on a part, preferably the middle, of the uppermost object in a stack of thin objects being in a recess of a package. The recess of the package for receiving the objects is at least areawise somewhat smaller than the exterior dimensions of the objects. With the aid of vacuum in the pick up and lay down head the uppermost object is lifted out of the package.

Then the pick up and lay down head of the application means is lowered down so that the object is brought into contact with the surface.
