Abstract: The application discloses a gluing apparatus for an adjustable machine for manufacturing corrugated boxes of a plurality of sizes. The apparatus includes an automatic glue dispensing head for applying glue to a corrugated box blank. The dispensing head is operatively connected to a mechanism for indexing the dispensing head towards and away from a centerline of the box manufacturing machine. The indexing mechanism is driven by a means operatively connected to an adjustable assembly station on the box manufacturing machine. Adjustment of the assembly station to produce a preselected size box correspondingly indexes the glue head towards or away from the centerline to a predetermined direction and distance from the centerline of the machine to apply glue to the box blank.

Abstract: This relates to a machine for assembling end units with container bodies. The container bodies have cylindrical open upper ends over which a cylindrical lower portion of an end unit or dome is telescoped with the overlapping portions being adhesively bonded together. The machine receives the end units serially and by way of a Ferris wheel type conveyor moves the end units first to an adhesive applicator where a band of adhesive is applied to the interior of each end unit, after which each end unit is then telescoped over and pressed into position relative to an associated body. The operation of the machine is continuous.

Abstract: This invention is directed to a high speed cold adhesive curing process and apparatus therefor, useful in the assembly and fastening together of fibrous surfaces such as the surfaces of corrugated Kraft paper cardboard boxes. The invention is directed to a process for adhering two fibrous surfaces together by means of a liquid cold cure adhesive comprising: (a) spraying liquid cold cure adhesive on the interface surface of one of the fibrous surfaces in a thin discrete particle pattern; and (b) pressing the two fibrous surfaces together under high pressure sufficient to cause the solvent carrier in the cold cure adhesive to disperse into the interstices of the fibres of the two surfaces, thereby enabling the cold cure adhesive particles to rapidly secure the two surfaces together.

Abstract: An improved apparatus for clamping and rotating containers which includes a rotatably supported table for supporting and rotating a container about an axis, drive means connected to the table for rotating the table about the axis of rotation, a plurality of jaws movably mounted on the table for alternately engaging and releasing a container to be rotated, jaw-positioning means engageable with the plurality of jaws for moving the jaws into and out of engagement with a container, and actuator means for actuating the jaw-positioning means. A method of applying sealant to the inside of a container at the juncture between the inner surfaces of the bottom closure member and the sidewall thereof is also disclosed.

Abstract: A carton blank folding and gluing system having a feeder unit, a variety of units, a gluing unit, a stacking unit and belts for continuously conveying carton blanks to the units. The carton blanks are of various types and sizes. The system operates to move only the attachments required for folding or gluing the carton blank to predetermined positions in the units and to retract attachments not required for folding or gluing the carton blank. A control device is provided, in which the predetermined positions of all of the attachments required for folding or gluing the carton blank are automatically determined, stored and outputted by receiving a signal representative of the type of carton blank and signals representative of the dimensions of particular parts of the carton blank.
