The engagement elements are configured to erect the side regions of the cardboard blanks when the erecting device transitions from the receiving configuration to the forming configuration. The erecting device is configured to move the bottom regions of the cardboard blanks relative to each other when transitioning from the receiving configuration to the forming configuration.

A corrugated plastic box and a method for manufacturing a corrugated plastic box from a blank are provided. The method includes the steps of forming rounded edge seals on the perimeter edges of the blank, pre-sealing portions of the blank to form a plurality of areas in which major and minor flap slots and a glue tab are desired, ultrasonically scoring the blank to form a plurality of flap score lines, and cutting the blank through the plurality of pre-sealed flap slots and glue tab, leaving a sealed edge.

In one aspect, there is provided a combination for use in readying a cutting cylinder is rotatably mounted to a frame in a box-forming production line. The cutting cylinder has a cylinder reference indicium. The combination includes a transfer member with a transfer member reference indicium thereon, a cutting member that includes a base and a cutting blade, and a connector structure that is configured to releasably mount the cutting member to the transfer member. The cutting member is movable to a selected distance along the first axis from the transfer member reference indicium. The connector structure includes a locking structure positionable in an unlocking position for separating the cutting member and the transfer member, and a locking position to lock the connector structure to the transfer member, so as to hold the cutting member at the selected distance from the transfer member reference indicium.

The present invention provides a method to form cardboard boxes (B) by gluing into a box-forming machine (100) from sheets (S), said machine (100), a computer program with instructions for said machine (100) to execute said method, and a computer-readable device that has stored said computer program. In this method, a stage (f) of the movement of inserting a pintle (20) into a mold (30) starts with a controlling element (70) when the position (P) of a drag element (11) of sheet (S) to a delivery position, where you place a sheet (S) aligned between said pintle (20) and mold (30), it corresponds to a second intermediate position (P2) between a source position and said delivery position; and a stage (b) of activation of a supplying actuator (61) starts with a controlling element (70) to supply a sheet (S) subsequent to the source position, when the position (P) of said drag element (11) corresponds to a third intermediate position (P3) between said source position and said second position (P2).

The composite structure includes a fiber-containing layer, such as a fiberboard layer or other layer having fibers from natural and/or synthetic sources, and a mineral-containing layer covering the fiber-containing layer. The fiber-containing layer and mineral-containing layer can be shaped, sized and manufactured such that the composite structure formed therefrom is capable of being machined to form a storage article. The composite structure has advantages in that it can improve whiteness, opacity, ink adhesion, materials reduction, barrier properties, recyclability, and printability. The composite can reduce polymer mass requirements for heat seal, barrier, and fiber adhesion. Further improvements include economics, pliability, and flexibility that is increased over the pliability of the fiber-containing layer alone.

Methods and apparatus for stripping away portions of substrate are disclosed herein. In some embodiments, a flexible and/or soft impact-element(s) rotates around a rotation axis to drive a peripheral portion across a substrate plane of the substrate and/or to repeatedly collide with the substrate. At least some of the collisions are effective to partially dislodge or to strip away portion(s) of substrate.

The cutting cylinder has a cylinder reference indicium. The combination includes a transfer member with a transfer member reference indicium thereon, a cutting member that includes a base and a cutting blade, and a connector structure that is configured to releasably mount the cutting member to the transfer member. The cutting member is movable to a selected distance along the first axis from the transfer member reference indicium. The connector structure includes a locking structure positionable in an unlocking position for separating the cutting member and the transfer member, and a locking position to lock the connector structure to the transfer member, so as to hold the cutting member at the selected distance from the transfer member reference indicium.

A continuous case blank delivery system, its function and use are provided. The main components of the system include a staging area, an elevator area, a safety door positioned therebetween, and a carriage movable therebetween when the safety door is in the open position. The elevator has a right side wall a left side wall and an elevator platform. The platform is vertically moveable between a lowered position and a predetermined height. In the lowered position the elevator platform is below the height of the carriage. The walls each define a plurality of support finger housings, each of which contain an extendable support finger. When the elevator platform is in the lowered position each support finger is retracted and contained entirely within its housing. When the elevator reaches a predetermined height each support finger is extended.

A machine a mandrel assembly includes a mandrel having an external shape complimentary to an internal shape of at least a portion of a container, a first lift mechanism operatively coupled to a first servomechanism to wrap a first portion of a blank about the mandrel, a second lift mechanism operatively coupled to a second servomechanism to wrap a second portion of the blank about the mandrel, and a folding arm coupled to the first lift mechanism and operatively coupled to a third servomechanism. A control system is in communication with the first servomechanism, the second servomechanism, and the third servomechanism and is configured to transmit a signal to each of the servomechanisms to independently control movement of the first lift mechanism, the second lift mechanism, and the folding arm to wrap at least the first and second portions of the blank about the mandrel to form the container.

A carrier for holding a plurality of containers includes a top panel having a first plurality of container openings, at least one container retention flap foldably connected to the top panel and having a second plurality of container openings aligned with respective container openings of the first plurality of container openings, at least one first container retention tab foldably connected to the top panel and extending toward a respective container opening of the first plurality of container openings, and at least one second container retention tab foldably connected to the at least one container retention flap and extending toward a respective container opening of the second plurality of container openings, the at least one second container retention tab is circumferentially offset relative to the at least one first container retention tab, and at least one reinforcement panel positioned between the top panel and the at least one container retention flap.
