3	Apparatus and method for sealing box blanks	US317747	1989-03-02	US4979932A	1990-12-25	Paul Burnside
A method and apparatus for the manufacture of folded paper boxes with a hemmed seal. One of two edges to be overlapped is skived and folded into a hem. After the edges are locally heated, blanks move individually and successfully along a conveyor for folding and sealing. Just before sealing, the hemmed edge passes between a hem holder and the conveyor to maintain the hemmed edge. The hem holder is heated to prevent the edges from cooling. In one embodiment hot air directed onto the hem from the hem holder forms an air cushion between the hem and the hem holder thereby to minimize any contact between the hem holder and the blank.

The press means are intended to coact with selected parts (2, 3) of the blanks for folding them up or down from the plane of the blank during their passage through the apparatus. The blanks are arranged to be conveyed through the apparatus at the same speed as that at which the conveying means is driven. The latter is guided in a helical path by an elongate, rigid structure (8, 9) forming continuous support for the conveying means. During the entire folding operation the operative ones of the press means attached to the conveying means press against the same area on the part of the blank with which they coact.
7	Apparatus for folding paper boxes	US413790	1989-09-28	US5092827A	1992-03-03	Hugh A. McAdam, III; Robert Tremblay; James Pacocha
Apparatus and a method for folding flaps onto panels formed in folded box blanks, particularly those constructed from corrugated cardboard. As a blank advances along a paper line, a first station engages leading edges of the flaps and forces the flaps into an intermediate plane representing a partial folding operation. Then a second station controls the relative velocities of the flaps along the paper line with respect to the panels to compensate for skew that can occur in other stations. A final station completes the folding operation. The resulting fold is made about an axis, or fold line. If the flap is to be folded about a prestamped score line, the fold and score lines are coextensive. Typically the flaps are folded 180.degree. and the first station produces intermediate folds that are displaced 90.degree. from the panels.

Apparatus for folding blanks particularly those constructed from corrugated cardboard. As a blank advances along a paper line pathway, a first station engages the leading edges of the blank flaps and forces the flaps into an intermediate plane. A second station controls the relative velocity of the flaps along the paper line with respect to the panels to compensate for skew that can occur at other stations. A final station completes the folding operation. The second station includes driven rollers that engage opposite sides of each of the flaps. Independently controlled motors drive these rollers in response to the velocity of the blanks along a paper line pathway and any required offset for skew compensation. The controls can be remotely located from the station. Moreover, the station can accommodate blanks of different thicknesses, position the rollers at different locations on different flaps and accommodate cartons with different widths.
