A machine for forming a container from a blank of sheet material includes an outer body frame, a mandrel mounted to the body frame, a lifting assembly coupled to the body frame, and a lateral presser assembly and a folding arm assembly coupled to the lifting assembly, wherein the lifting assembly moves the lateral presser assembly and the folding arm assembly in a first direction and an opposite, second direction. A folding arm servomechanism is operatively connected to a folding arm of the folding arm assembly and rotates the folding arm relative to the mandrel to wrap a first portion of the blank around the mandrel. A lateral presser servomechanism is operatively connected to an engaging bar of the lateral presser assembly and rotates the engaging bar relative to the mandrel to wrap a second portion of the blank around the mandrel to at least partially form the container.

A method for forming a container from a blank assembly including a tray blank and lid blank includes folding a first portion of the blank assembly about at least a first face of a first mandrel to form a partially formed container, and transferring the partially formed container towards a second mandrel using a transfer assembly that extends through the first face of the first mandrel. The method also includes transferring the partially formed container from the first mandrel to the second mandrel along a pair of guide rails extending between the first mandrel and the second mandrel, wrapping a second portion of the blank assembly about at least a first face of the second mandrel to form the container, wherein the first face of the second mandrel opposes the first face of the first mandrel with respect to a vertical direction, and ejecting the container from the second mandrel.

A box folding structure for folding a box is disclosed. The box folding structure includes a curved folding member and an erect folding member. The curved folding member can include a curved surface, a retaining surface, and a first inclined folding surface. The curved surface can be used to fold dust flaps of a box. The retaining surface can be adjacent to the curved surface and can be used for folding a first outer flap of the box. The first inclined folding surface can be defined on a portion of the curved folding member that is adjacent to the curved surface and can be used for folding a second outer flap of the box. The erect folding member can be laterally offset from the curved folding member and can include a second inclined folding surface opposite the first inclined folding surface for folding a second outer flap of the box.

A box suitable for the packaging of a consumer product is formed by helically wrapping an elongated continuous strip of material around a mandrel to form a main body with a plurality of bands. In one embodiment, adjacent bands partially overlie one another to form a multi-paneled main body with an open top end and an open bottom end. An adhesive is disposed within the region of contact between adjacent bands to retain the shape of the main body. First and second sets of slots are formed in the main body to create flaps dimensioned to selectively enclose the open top and bottom ends, respectively. To define the flaps and promote pivotal articulation, the main body is also preferably provided with score lines. By adjusting the configuration of the mandrel, a customized box can be constructed that is sized to receive a consumer product with limited wasted space.

A method of forming a paperboard packaging container from a rectangular body blank is disclosed, the method including the following steps: a) providing a rectangular body blank made from a laminate sheet material; b) forming a tubular container body from the rectangular body blank, the container body having a first end with a first body opening and a second end with a second body opening; c) sealing together the first and the second side edge in a but-to-but seal using a sealing strip having a sealing strip width; d) presenting the tubular container body to a crease line forming station; e) closing the second body opening by pressing a paperboard disc into the second body opening; f) forming a curled second edge by folding or rolling the second end of the container body wall inwardly; g) filling the packaging container with bulk solids; and h) closing the first body opening.

A method for forming a container using a machine includes extracting a blank from a magazine, transferring the blank in a blank transfer direction X, and positioning the blank on a deck. The method also includes translating a pick-up assembly from a first end to a second end along a horizontal direction Y perpendicular to the blank transfer direction X, the translating including transferring a web from a first location proximate the first end to a second location proximate the second end. The method further includes depositing, at the second location, the web into an at least partially overlying relationship with the blank to form a blank assembly, transferring the blank assembly along the deck in the blank transfer direction X while translating the pick-up assembly from the second end back to the first end, and wrapping the blank assembly around a mandrel to at least partially form the container.
