In a folder-gluer, push-out forces by an air cylinder and a push-out spring mechanism are set such that: (1) when downstream portions of first and fourth panels are passing through a second bending plate, the second bending plate is pushed outwardly in a width direction by the push-out forces to extend the downstream portions of the first and fourth panels in the width direction; and (2) when upstream portions of the first and fourth panels are passing through the second bending plate, the second bending plate is pushed back inwardly in the width direction by the resistance force applied to the second bending plate by the first and fourth panels so as not to extend the upstream portions in the width direction, and wherein the push-out forces are not varied by a control while the first and fourth panels are passing through the second bending plate.

A box erecting device for folding a box is disclosed herein. The box erecting device includes a folding plate and a lid erecting system. The folding plate is configured for erecting a box, and a folding notch including a first edge and a second edge is formed in the folding plate. The first edge is configured for erecting a first dust flap of the box, and the second edge is configured for erecting a second dust flap of the box. The lid erecting system is disposed adjacent to the folding plate and is configured for erecting a lid of the box. The lid erecting system includes a tab funnel and a folding tool. The tab funnel includes a ramp for retaining the dust flaps while closing the lid. The folding tool includes a hooked ramp for causing a distal end of the lid to be inserted into the box.

In a box assembly device, a holding mechanism causes one of bottom boards to contact a first jig and folds the bottom board inside, while the holding mechanism holding the box material in a state where the box material is developed in a cylindrical shape from a folded state. The folding mechanism folds the bottom flap inside so as to overlap with one of the bottom boards. The holding mechanism causes the other bottom board to contact the second jig while holding the box material and folds the other bottom board inside and upwardly so as to overlap with the bottom flap to engage the bottom boards with each other.

The technology described herein generally relates to particular form of folded package and the method of forming that folded package. The package packages loose particles into a conical container and secures the filling with a folded distal end. More specifically, loose plant matter, such as crumbled dried leaves, are supplied as filling and the package may further be provided with a fluid core.

A packing box folding system, and the packing box folding system including a transfer conveyor on which transfers the packing box from a packing box introducing position to a folded packing box discharging position; a fixed guide panel which extends between the packing box introducing position and the packing box discharging position and is disposed on one side of the transfer conveyor in the width-direction; and a movable suction device which is disposed on the side opposite to the fixed guide panel in the width-direction of the transfer conveyor and is movable between the packing box introducing position and the packing box discharging position, wherein the movable suction device suctions the side surface of the packing box, which faces the side surface in contact with the fixed guide panel, and presses the suctioned side surface inward in the width-direction.

An improved mailer folding apparatus that forms mailers from mailer blanks. The mailer folding apparatus comprises a transport assembly and one or more folding assemblies. The transport assembly moves mailer blanks and/or mailers through the mailer folding apparatus. The one or more folding assemblies may each comprise a folding system and a carriage system. The folding system may selectively allow for the folding of a mailer blank into a mailer. A carriage of the carriage system may move the folding system longitudinally between different positions relative to the transport assembly. An engagement system separate from the carriage system or integrated into the carriage system may engage and disengage the folding system with the transport system for selectively feeding a mailer blank through the folding system, or disengage the folding system for allowing a mailer blank or folded mailer to bypass the folding system.
