A method of mechanically applying cover-slips onto slides provided with specimens for microscopic examination, wherein the slides are fed to a coating station at which a solvent film is applied without mechanical contact between the coating member and the specimens and then fed to an application station wherein the cover-slips, which have an adhesive layer on the slides thereof arranged to bear against the solvent layer, are applied onto the solvent layer.

A method for forming a composite assembly of a discrete slide provided with a specimen for microscopic examination and a cover-slip comprising the steps of transporting a slide having the specimen thereon in a horizontal plane past at least a first and second station, positioning a nozzle for dispensing a liquid solvent adjacent the surface of the leading end of said slide, depositing said solvent directly on said slide and forming a small but restricted liquid excess swelling thereon, partially raising said nozzle from said slide, moving said slide through said first station and forming a liquid solvent film on said slide, interrupting the formation of the film immediately before the opposite end of the slide passes the nozzle, transporting said slide with solvent to said second station feeding a flexible cover-slip toward said slide at said second station, said cover-slip having a pre-applied dry adhesive layer on one side adapted to be activated by said solvent, said cover-slip being fed with its leading end first at an angle to said slide while said slide is transported past said second station, said slide being transported past said second station at a speed substantially equal to the feeding of said cover slip, positioning a roller distinct from said slide and said cover-slip at a predetermined distance above said slide thereby to form an excess of solvent in the angle between the cover slip and the slide, and simultaneously pressing said cover-slip to said slide from the leading end to the trailing end thereof so as to squeeze any excess solvent and air from between said cover slip and said slide, and thus form said composite assembly.
