A conversion unit converting a first continuous web substrate into a second substrate in the form of converted blanks of predetermined length. On account of cutting tool rotation speed, the web moves at various speeds for cutting the web cut lengths and other aspects of cutting and transport process having a constant input speed. The unit includes a first motorized arrangement for producing a first run driving of the web, a sheeter having rotary tools for cutting the web into blanks, a second motorized arrangement for producing a second run driving of the substrate, the second arrangement being positioned in the immediate proximity of the sheeter, and at least one station having rotary tools for converting the blanks. A speed of rotation of the second arrangement varies during a cycle of rotation of the tools of the sheeter, comprising a phase at constant tangential speed, substantially equal to the speed of rotation of the tools of the sheeter, during which the cut is made, a speed reduction phase, during which a length of the web, dependent on the difference between the length of the blank and an extension of the periphery of the tools, is kept upstream of the second arrangement, and a speed increase phase, during which the substrate is discharged downstream of the second arrangement.

A system for forming a pressware product comprises rollers, a scoring tool, a scoring station actuator, a forming tool, and a forming station actuator. The rollers pull the web along a path having an angle. The scoring tool receives the material from the rollers and includes a vertically shiftable scoring punch with an edge that extends about an outline of the pressware product and a striker plate. The scoring station actuator shifts the scoring tool to form a slot in the web. The forming tool receives the scored web and includes a vertically shiftable positive mold assembly and negative mold assembly. The forming station actuator shifts the positive mold assembly to press against the web and form the pressware product.

Techniques for erecting folded-flat cases are described herein. In a first example, a grasping tool is moved along a supporting beam in two directions in a first dimension. The supporting beam is configured for movement along first and second beams two directions in a second dimension. The grasping tool is configured to grasp and open a folded-flat case. In a second example, the grasping tool is configured with a rotation arm. A rotation-control beam defines a track, within which a pin connected to the rotation arm is configured to slide. A motor drives the rotation-control beam in two directions in one dimension, to thereby rotate the grasping tool.

This invention relates to an apparatus for manufacturing a container, the container being made of paperboard and being formed from at least two elements adhered together. An apparatus for use in manufacturing a container comprises a first inlet connected to a supply of dry steam; a second inlet connected to a supply of hot air; a mixing chamber, the first inlet and the second inlet being fluidly connected to the mixing chamber such that a flow of dry steam from the first inlet mixes with a flow of hot air from the second inlet; and a delivery nozzle fluidly connected to the mixing at least one of said elements.

A box forming carousel apparatus including a frame, a rotating carton retainer, a first side carton folding assembly, a second side carton folding assembly and an axle. The frame has a bottom, and first and second sides. The rotating carton retainer is rotatably coupled to the frame and has a plurality of slot assemblies radially spaced apart, each slot assembly having a leading wall, a following wall and a base wall. Each slot assembly structurally configured to retain a box therein. The first side carton folding assembly is structurally configured to fold a plurality of flaps of the box on a first side thereof. The second side carton folding assembly is structurally configured to fold a plurality of flaps of the box on a second side thereof. The axle extends between the first side and the second side of the frame spaced apart from the bottom of the frame.

A system for forming a pressware product from a web of a roll of material comprises a positive mold, a negative mold, a heating element, an actuator, a force sensor, and a control system. The positive mold forms a top surface of the pressware product. The negative mold forms a bottom surface of the pressware product. The heating element is coupled to the positive mold or the negative mold. The actuator shifts the positive mold or the negative mold to cut and form the pressware product in a single stroke. The force sensor detects the forming force applied by the actuator, and the control system directs the actuator to adjust the forming force.

A forming machine (2) for forming a box (60) from a blank (6) made of paper or cardboard, including a base (6a) and side panels (6a, 6b, 6c, 6d) connected to the base (6a), comprises: a working zone configured to receive the blank (6); a plurality of folders (21) positioned in the working zone and configured to interact with the side panels (6a, 6b, 6c, 6d) of the blank (6) to fold them and dispose them parallel to a vertical direction (V), with respective lateral borders juxtaposed to define vertical edges of the side wall of the box (60); a plurality of heads (22), including respective pressers (222) that are movable towards and away from each other, wherein each presser (222) is configured to press a respective vertical edge from the outside of the space inside the box (60).

Techniques for corrugate and chipboard knocked-down case inspection and assembly are described herein. In one example, the disclosed techniques include a method to inspect and assemble a knocked-down case. In the example, a measurement of at least one aspect of the knocked-down case is obtained. A difference is determined between the obtained measurement and a standard measurement and/or a range of standard measurements. Programming of a case-handling tool is executed that is based at least in part on the determined difference. In an example, the programming is configured to adjust for and/or compensate for differences between the actual knocked-down case and a knocked-down case that is within a specification. A case-handling tool is operated responsive to the executed programming to at least partially erect the knocked-down case into an erected case.

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.

This invention relates to a container pre-cutting system, applicable to multilayer and/or single-layer (3) container forming machines (4) that provide intermittent advances to the multi-layer and/or single-layer material with a length according to an advance step of the machine; said system being suitable for making a lower pre-cut (32) on the lower surface and an upper pre-cut (32) on the upper surface of the multilayer and/or single-layer material (3). The system comprises a lower pre-cutting device (1) and an upper pre-cutting device (2), provided with respective lower (11) and upper (21) blades having relative vertical movement with respect to the multilayer and/or single-layer material (3); and wherein the lower pre-cutting device (1) and the upper pre-cutting device (2) are separated in the advance direction of the multilayer and/or single-layer material (3) at a length approximately equal to a multiple of the advance step of the machine.
