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.

The technology described herein generally relates to particular form of 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 method of at least partially forming a carton includes obtaining a blank comprising at least one fold line, heating an interior surface of the blank along the at least one fold line to form a heated fold line, and folding the blank about the heated fold line.

A method for manufacturing a paperboard bottle and spiral-wound paperboard bottle. The bottle has a tubular body portion, a shoulder and neck portion having a circular cross-section narrowing from the body portion to a circular mouth. The paperboard bottle is a liquid packaging board having thermoplastic polymer coating on both sides. The method includes cutting a planar elongated blank from a packaging board sheet. Protecting exposed cut raw edge of the first longitudinal edge against absorption of liquid. Securing the first end of the blank to a rotatable mandrel having a rotation axis (x) and an outer shape corresponding to the shape of the bottle. Rotating the mandrel to wind the blank spirally onto the mandrel, so that the longitudinal edges overlap applying heat-sealing energy and pressure, onto the overlapping longitudinal edges to form a bottle with hermetically sealed spiral seam and removing the mandrel from inside the bottle.

A method and a system for erecting boxes from box templates of different sizes, said method comprising the steps of: adjusting a size of a frame according to a size of a box template which should be erected; wrapping the box template to be erected around the frame; and separating the frame from the box template.
