A machine is provided for automatically attaching cover slips to microscope slides having specimens for microscopic examination, including a first magazine for microscope slides, a second magazine for cover slips, and a reciprocating transport means for transport of slides and cover slips from the respective magazines to a working station. The apparatus further includes a pump for application of adhesives to slides, and a lifting means for lifting and placing of a cover slip on a slide which is provided with adhesive. The two magazines are located on opposite sides of the transport means, and that the transport means is arranged to carry a slide from the first magazine to the working station in an outgoing movement from a home position, and to carry a cover slip from the second magazine to the working station in a return movement. The lifting means is arranged to lift a cover slip from the transport means before the latter is allowed to start its outgoing movement, and further is arranged to place a cover slip on the slide on the working station with terminated outgoing movement of the transport means and after application of adhesive to the slide by the pumping means. The transport means is arranged to bring the slide with attached cover slip back to the first magazine during its return movement, at the same time as a new cover slip is carried from the second magazine to the working station.

Apparatus as recited in claim 1, wherein said main frame further comprises first and second brace components disposed adjacent opposite longitudinal ends of each said cassette main body to prevent substantial movement thereof in a first direction perpendicular to said idler roller axis, but to allow movement thereof in a second direction perpendicular to said axis and perpendicular to said first direction; said pressure plate being substantially fixed with respect to said main frame, and said spring components being disposed between said pressure plate and said cassettes, so that movement of said cassettes in said second direction is against the bias of said spring components. 7. Apparatus as recited in claim 6, wherein said main frame comprises first and second side plates, said first and second brace components comprising first and second cross brace shafts disposed in parallel to said idler roller axis and extending between and interconnecting said first and second side plates. 8. Apparatus as recited in claim 7, wherein said pressure plate is secured to and extends between said first and second side plates. 9. Apparatus as recited in claim 1, wherein each of said idler rollers has an axial dimension of less than one inch. 10. Apparatus as recited in claim 1, wherein said idler roller assembly further comprises a mounting assembly for mounting said idler roller assembly to said main frame means so that a disposition of said cassettes along said axis of said drive roller is adjustable to dispose two of said plurality of cassettes along the edges of business forms in the direction of travel through said apparatus. 11. Apparatus as recited in claim 10, wherein said main frame comprises first and second interconnected side plates, and wherein said mounting assembly comprises first and second locator plates, one disposed between each said side plate and said plurality of cassettes, and wherein at least one of said locator plates is adjustably disposed with respect to the side plate adjacent thereto. 12. Apparatus as recited in claim 1, further comprising an outfeed conveyor for conveying business forms out of operative association with the at least one drive roller and idler rollers, said outfeed conveyor being operatively coupled to said drive assembly for being driven thereby. 13. Apparatus for sealing pressure sensitive cohesive patterns on business forms, comprising: first and second drive rollers mounted for rotation about parallel rotary axes; a drive assembly for rotating the first and second drive rollers about the axis thereof; a main frame mounting a plurality of idler roller cassettes in operative association with the drive rollers to apply a compressive pressure to business forms passing between them, each idler roller cassette comprising a pair of idler rollers, each idler roller being mounted for rotation about a respective idler axis that is parallel to the drive axis of a respective one of the first and second drive rollers; a plurality of spring components, each for applying spring pressure to a respective idler roller cassette; and a pressure plate for engaging the plurality of spring components to uniformly compress the same to urge said idler roller cassettes toward said first and second drive rollers. 14. Apparatus as recited in claim 1, wherein said drive assembly includes a motor mounted adjacent said main frame. 15. Apparatus as recited in claim 13, wherein said pressure plate and said spring components urge said idler roller cassettes so that said idler rollers cooperate with said first and second drive rollers to apply a compressive pressure to business forms passing between them of at least about 300 pounds per lineal inch. 16. Apparatus as recited
