Abstract
Abstract A case sealer including the usual case sealing devices is automatically adjustable for random size cases. A switching device in the input region of the sealer senses the sizes of the cases entering the sealer, and a brake responsive to the switching device stops any case differing in size from a preceding case. The sealer speeds up in response to the switching device for clearing the sealer of all the cases preceding the different size case, and when the sealer is cleared, an axially movable shaft is adjusted to position cam and follower means for vertically adjusting a frame supporting the sealing devices to fit the height of the different size case. A pair of horizontally adjustable members supported on the frame carry glue appliers and guide rails and are horizontally adjusted by a second cam and follower means to fit the width of the different size case. When the shaft is positioned, the brake is released, and the sealer continues operation.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
218 words
In an automatic random case sealer having devices including guide rails, flap opening and closing means, glue appliers, and means for pressing glued flaps into sealed engagement, the improvement comprising: a. switch means in an input region of said sealer for sensing the size of each one of said cases entering said sealer; b. brake means responsive to said switch means for stopping any one of said cases differing in size from a preceding one of said cases; c. means responsive to said switch means for clearing said sealer of all of said cases preceding said different size case; d. an axially movable adjusting shaft; e. means responsive to said clearing means for positioning said shaft; f. a vertically adjustable frame supporting said devices; g. first cam and follower means positioned by said shaft for adjusting said frame to fit the height of said different size case; h. a pair of horizontally adjustable members supported on said frame and carrying said glue appliers and said guide rails for said cases; i. second cam and follower means positioned by said frame for adjusting the horizontal separation of said members to fit the width of said different size case; and j. means responsive to said positioning of said shaft for releasing said brake means after said positioning of said shaft.
