Abstract: Apparatus is disclosed for folding and compressing corrugated container blanks to which adhesive has been applied. The apparatus effects the formation of the completed container by folding the blank and subsequently compressing and maintaining it in the compressed position until the adhesive sets. The apparatus includes a conveyor and rail mechanism for folding the blanks, a center compression unit for compressing the central portion of the blank, a side compression unit for compressing the side portions of the blank, skate wheel rollers for maintaining compression, and a spring-loaded hold-down conveyor for accumulating the completed containers.

Abstract: A catalytic reactor is made by providing a generally cylindrical catalytic substrate of oval transverse section and clamping the same between paired housing shells to form a housing of oval section spaced from the substrate by means of a pair of wire mesh ropes seated within a corresponding pair of grooves extending around the periphery of the substrate at axially spaced locations. Each rope is compacted from a matrix of multiple layers of resilient stainless steel knitted wire and is interlocked with the housing by means of a pair of inwardly opening channels of the housing spaced axially by an inwardly projecting rib of the housing. The grooves in the substrate are pressed radially into the latter while the same is in a plastic uncured condition, thereby to compact and reinforce the grooves to withstand the localized compressional force of the ropes seated therein after the substrate is cured and hardened and clamped between the housing shells.

Abstract: An apparatus for producing a carton in a folded condition for storage and handling and whereby the carton can then be unfolded for use. The apparatus is designed for handling different types of blanks which, generally speaking, include a plurality of panels comprising side, top and bottom panels of the carton. The bottom panels are provided with flaps, and a first folding structure is provided for folding the bottom panels over onto adjacent side panels. Simultaneously, second folding means serve to fold flaps over onto the associated bottom panels, and adhesive applying means serve to locate adhesive on the blanks in selected positions.

Abstract: An apparatus for producing a carton whereby the carton is initially obtained in the folded condition for storage and handling and whereby the carton can then be unfolded for use. The apparatus is designed for handling different types of blanks which, generally speaking, include a plurality of panels comprising side, top and bottom panels of the carton. The bottom panels are provided with flaps, and a first folding structure is provided for folding the bottom panels over onto adjacent side panels. Simultaneously, second folding means serve to fold flaps over onto the associated bottom panels, and adhesive applying means serve to locate adhesive on the blanks in selected positions. A third folding means folds the outside ends of the blank over onto the inside portions of the blank at which time folded flaps become adhesively secured. Additional adhesive or other handling means secure the outside ends of the assembly together whereby a flat condition of the carton is obtained.
