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.

A system for scoring a web of a roll of material comprises a plate, a scoring punch, a scoring station actuator, and a controller. The plate has a slot extending about a shape representing an outline of a pressware product. The scoring punch has a protruding blade operable to enter the slot of the plate. The scoring station actuator is configured to shift the scoring punch or the plate to press the blade against the web to form a slot in the web. The controller is configured to direct the scoring station actuator to press the blade to a first predetermined scoring depth within the web.

Disclosed is a corrugated paperboard box making machine which comprises a sheet feeding apparatus, a processing apparatus, a folder-gluer, a counter-ejector for stacking the box-structured corrugated paperboard sheets and separating them as a batch, a speed setting unit for setting a sheet feeding speed, and a control apparatus. The control apparatus is operable to execute a sheet feeding control processing of the sheet feeding apparatus such that a sheet feeding operation of feeding one corrugated paperboard sheet is successively repeated a number of times corresponding to the number of the given number of box-structured corrugated paperboard sheets in the batch, and a sheet feeding stop control processing of, when the sheet feeding speed is greater than an allowable speed, the sheet feeding apparatus such that the sheet feeding operation is stopped at least once after execution of the sheet feeding control processing.

A paper box package forming apparatus includes a continuous feeding device, a box folding mechanism and a cover sealing mechanism. The continuous feeding device includes a paperboard stacking frame, an adsorption mechanism and a roll extrusion conveying mechanism. A paperboard is absorbed from a back side of the paperboard stacking frame through the adsorption mechanism and conveyed to a box folding device through the roll extrusion conveying mechanism. The box folding device includes a downward-pressing inner punch, a box folding outer mold and a pushing mechanism. The pushing mechanism conveys a bottom box to the cover sealing mechanism. The downward-pressing and attaching mechanism includes downward-pressing driving mechanism, a top-pressing plate, side-pressing plates and overturning cylinders. The side-pressing plates are hinged to side edges of the top-pressing plate through the driving of the overturning cylinders.

A converting assembly performs a plurality of conversion functions on sheet material to convert the sheet material into packaging templates. The converting assembly includes a plurality of tool rollers. Each of the tool rollers has one or more conversion tools thereon. The one or more conversion tools on an individual tool roller are configured to perform a subset of the plurality of conversion functions that convert the sheet material into packaging templates.

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 system for decurling a web from a roll of material comprises rollers, a decurling station actuator, a sensor, and a controller. The rollers are configured to pull the web along a path with an angle. The decurling station actuator is configured to shift one of the rollers relative to the other rollers to adjust the angle of the path. The sensor is configured to sense a characteristic of the roll of material and generate sensor data. The controller is configured to receive a signal representative of the sensor data and direct the decurling station actuator to shift one of the rollers based at least in part on the sensor data.

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).

A sheet stacking device is provided with a hopper unit configured to stack a sheet, a feeding unit configured to feed out the sheet to the hopper unit, a distance detection unit configured to detect an inter-sheet distance, in the vertical direction, between a rear end portion of the sheet that is preceding and a tip end portion of the sheet that is subsequent, and an output unit configured to output a behavior stabilization command for the sheet based on the inter-sheet distance.

A converting machine is used to convert sheet material into packaging templates for assembly into boxes or other packaging. The converting machine includes a converting assembly that performs a transverse conversion function, a longitudinal conversion function, and an angled conversion function on the sheet material to create the packaging templates. The converting machine includes a tool head with a converting instrument. The orientation of the converting instrument is adjustable to enable performance of the angled conversion function and at least one of the longitudinal conversion function and the transverse conversion function.
