A device supports first and second flaps on a box traveling on a conveyor, the conveyor traveling at a speed in a direction. The device includes a cam track having a selected profile. The device includes a drive mechanism, wherein at least a portion of the drive mechanism travels proximate the cam track in the direction at substantially the speed of the conveyor. First and second mounting blocks are pivotally attached to the drive mechanism, including first and second cam followers for engaging the cam track; first and second fingers; and first and second hooks attached to the first and second fingers and configured to engage and hold the first and second flaps on the box. Relative positions of the first and second fingers with respect to the box change as the drive mechanism travels along the cam track.

A multivariable perforated adjustable height box is provided with improved folding, bending, and separation of adjacent panels. The multivariable perforated adjustable height box may include a box, columns, rows, glue tabs, column scores, row scores, perforations, cuts, skips, and bundle breakers. Perforation patterns may be irregular, angled, shifted, or otherwise configured to increase usability, strength, and/or other aspects of the packaging. A method to produce a packaging device with improved folding, bending, and separation of adjacent panels using the multivariable perforated adjustable height box is also provided.

Processes, assemblies, and sleeve blanks for forming a two-piece paper container are provided in which the sleeve blank includes an adhesive printed onto the sleeve blank while the sleeve blank is still part of the paper web. The adhesive can optionally be printed onto the sleeve blank in-line with printing a graphic on the sleeve blank prior to providing the sleeve blank to a container forming machine that wraps and seals the sleeve blank to a bottom blank.

In a method of aligning an upper and a lower changeable tool (2, 10, 18) in a device for processing, e.g., sheets of paper, provision is made that with the aid of at least one digital camera (50, 51), the upper changeable tool (2) is aligned with a sheet that has been moved in and the lower changeable tool (18) is aligned relative to the upper changeable tool (2) after the sheet has been moved out.

The present invention relates to a box forming machine for forming boxes of different shapes and sizes, comprising a forming station including an operating space, demarcated by upper and lower devices and receiving a box during the forming thereof, without horizontal movement of said box; flexible, pressurizable, and heatable glue conduits connected to a plurality of glue application nozzles, configured for being positioned in different positions consistent with the size of the box to be formed, and at least one electrically-operated valve configured for applying said hot glue in respective relative positions of said glue application nozzles with respect to the box, according to operative parameters associated with the dimensions of the box to be formed, including dimensions of upper and lower flaps of said box and at least one working temperature of a hot glue to be applied previously input in a user interface connected to a control device.

Various embodiments of the present disclosure provide a case former configured to receive a case in a blank configuration, open the case into a tubular configuration, fold the lower minor flaps to manipulate the case into a partially closed-bottom configuration, square the case while in the partially closed-bottom configuration, and fold and tape the lower major flaps shut to manipulate the case into a closed-bottom configuration. The squaring step ensures that the case has a rectangular cross-section after taping rather than a rhomboid cross-section.

A container comprising a bottom and a sidewall extending upwards from the bottom and terminating at an upper free edge, said upper free edge of the sidewall forming an opening of the container, said sidewall and said bottom comprising an outer paperboard layer and a thin inner plastic foil layer, formed in a thermoforming operation, said upper free edge of the sidewall comprising a rim portion extending past the outer surface of the paperboard layer of the sidewall. The rim portion comprises a rolled up portion of an upper portion of the outer paperboard layer of the sidewall, said rolled up portion being covered by a portion of the thin inner plastic foil layer. In this way, a stiff upper rim is provided, while allowing the use of a very thin inner plastic foil layer.

A machine for forming cardboard boxes (B) from flat plates (P), which comprises a feeder of plates with a loader of plates, a sucker mechanism and a conveyor of plates; and a box forming station with a male device with a first rotary electric motor coupled to a first rotational monitoring device, and a male vertically insertable in a mold to form the boxes (B). A pusher member of the conveyor and a suction head of the suction mechanism are both movable by a same second rotary electric motor coupled to a second rotational monitoring device. The first rotary electric motor (11), the second rotary electric motor, the first rotational monitoring device and the second rotational monitoring device are jointly configured to controllably move the male independently of the controlled and synchronized movement of the pusher member and the suction head.
