Abstract A MACHINE FOR SEALING CASES HAVING UPPER AND LOWER TELESCOPED SECTIONS WITH BOTTOM AND TOP CLOSURE FLAPS RESPECTIVELY. THE LOADED CASES PARTIALLY TELESCOPED TO EXPOSE NORMALLY OVERLAPPED PORTIONS OF THE LOWER SECTION ARE FED TO THE MACHINE WITH THE FLAPS OF THE LOWER SECTION CLOSED AND THE SIDE FLAPS OF THE UPPER SECTION OPEN. AS THE CASE ENTERS THE MACHINE IT IS SO SUPPORTED THAT A FIRST BOTTOM SIDE FLAP SWINGS DOWNWARDLY AND MEANS ARE PROVIDED TO APPLY ADHESIVE TO PORTIONS OF THE THEREBY EXPOSED BOTTOM END FLAPS. AS MOVEMENT OF THE CASE CONTINUES SAID FIRST SIDE FLAP IS CLOSED AND THE OTHER BOTTOM SIDE FLAP SWINGS DOWNWARDLY AND ADHESIVE IS APPLIED TO THEREBY EXPOSED PORTIONS OF THE END FLAPS. ADHESIVE IS ALSO APPLIED TO THE EXPOSED BUT NORMALLY OVERLAPPED SIDEWALL PORTIONS OF THE LOWER SECTION AND AHDESIVE IS APPLIED TO THE INNER SURFACES OF THE SIDE FLAPS OF THE UPPER SECTION. THE OTHER SIDE FLAP OF THE BOTTOM SECTION AND BOTH SIDE FLAPS OF THE UPPER SECTION ARE THEN CLOSED AND THE CASE IS SUBJECTED TO VERTICAL COMPRESSION TO COMPLETE THE TELESCOPING OF THE SECTIONS AND IS THEN SUBJECTED TO LATERAL COMPRESSION THE COMPRESSIVE FORCES BEING MAINTAINED UNTIL THE ADHESIVE TAKES AN INITIAL SET.
