A blank for being formed into a container. The blank has a marginal area that includes a plurality of score lines for facilitating forming of the blank into the container. The score lines are positioned to facilitate formation of the container. A forming tool has features to facilitate forming the blank into the container.

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.

A paper lid that is mainly made of paper includes a top plate portion extending in a first direction, an inner fitting portion extending in a second direction and being continuous with the top plate portion, a peak portion extending in a third direction and being continuous with the inner fitting portion, an outer fitting portion extending in a fourth direction, facing the inner fitting portion at a distance, and being continuous with the peak portion, and a flange portion extending in a fifth direction, being continuous with the outer fitting portion, and including an end of the paper lid.

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.

The invention relates to a method and an apparatus for deep-drawing a tray (1) from fiber-based sheet material (2), such as polymer coated board. The apparatus comprises a female moulding tool (3), which comprises a cavity (7) for forming the tray bottom outwardly, a male moulding tool (4), which comprises a plunger plate (11) for forming the tray bottom inwardly, the plunger plate being movable with respect to the cavity for forming the tray, and clamps (6, 15) with an interface for holding the sheet material and forming a tray rim flange. According to the invention by laterally distancing at least one of the moulding tools (3, 4) from the sheet material leeway is provided for free forming of the tray side walls while wrinkling or tearing of the same is avoided. Spacer plates (13) may be positioned behind the plunger plate (11), to adjust its position in relation to the cavity (7) of the female moulding tool (3). The cavity may have a separate bottom plate (8) and spacer plates (9) there below, or screw means may be provided for adjusting the distance of the bottom of the cavity from the clamp interface and thereby varying the depth of the tray.

A method for producing a paper lid includes a first step of holding down an outer edge area of a blank that is mainly made of paper, a second step of forming an inner fitting portion in a central area of the blank, while holding down the outer edge area, and a third step of forming an outer fitting portion in the central area, where the inner fitting portion is formed, while holding down the outer edge area.

A meat tray sized and shaped to support raw meat is provided. The meat tray is composed of a paperboard material. The meat tray may include a generally planar base extending to a sidewall that extends transversely from the planar base to an angled outer transition which forms an outer periphery of a tray cavity. A rim of the meat tray is located at a terminus of the angled outer transition and extends away from the cavity. The rim may include an outer arcuate rim portion that extends and curves away from the outer transition and a planar flange extending from the outer arcuate rim portion and terminates at an edge. The edge faces downwardly with respect to the outer arcuate rim portion.

A method of erecting a carton from a blank, including: engaging the blank with a punch head against which the carton is formed, folding side portions of the blank against the punch head to form sides of the carton; folding outer portions of the side portions of the blank away from the punch head and against an external side of the carton; folding end portions of the blank against the punch head to form end portions of the carton; folding outer portions of the end portions of the blank away from the punch head and against an external end of the carton; and securing corner gussets formed between the side and end portions against sides or ends of the carton.
