Abstract: The disclosure relates to a method in the forming of packaging containers (1) which have sealing fins in which the packaging material is sealed inside-to-inside, and also projecting, double-walled corner flaps (8). In order to form a parallelepipedic packaging container, the corner flaps are folded down and sealed to the outside of the packaging container, which subjects a sealing fin running between the corner flaps to stresses which may entail untightness in the packaging container. This is avoided in that the sealing fin, prior to the downward folding operation, is deformed in that at least a portion of the fin (4) is laterally displaced in relation to adjacent portions of the fin.

Abstract: A box with integral corner reinforcements and a method of making the same is described. The method comprises folding the box from a prescored sheet of material so as to leave a flap adjacent each corner. The flap is prescored and is pushed towards its hinged corner whereby it buckles into a curved shape. The end of the flap is secured by gluing or stapling so as to stabilize the curved shape.

Abstract: A device incorporated in a facsimile transceiver or similar recording apparatus of the type using a roll of paper for removing the curl of the paper. The device has a regular transport path, an uncurl transport path, and a separator fixed in place at a position where the two transport paths branch off. The separator steers the paper to either of the two transport paths on the basis of the height of a curl existing at the leading edge of the paper. The separator has a generally triangular configuration which has an apex at the center in the widthwise direction perpendicular to an intended direction of paper transport and inclines from the apex toward opposite ends. As a result, the paper is admitted into the regular transport path or the uncurl transport path little by little from part of the leading edge thereof.

Abstract: A quarter folder machine for accepting half fold signatures and converting them into quarter signatures. The machine receives half signatures in an incoming shingle running at relatively low velocity, strips and accelerates the signatures to travel seriatim in a high speed stream which passes through camming and crimping means to create the quarter fold. A decelerating and re-shingling section then converts the stream back into an output shingle which runs at relatively low linear velocity but at a high rate in terms of signatures per hour--for transport to some subsequent processing device. The machine is characterized by a very high throughput rate. It is flexibly adjustable to match to the velocity of and setback of an incoming shingle from various sources, and yet to determine by choice the setback and velocity of the output shingle.
