摘要： A substantially crimpless and monolithic paperboard container lid and method of making same is provided. The lid comprises a single contiguous molded paperboard body configured to conformingly couple to a top periphery of a container for covering the container's opening. The body includes a sealing ring located adjacent the body's periphery. The sealing ring includes a sealing channel composed of a radiused cross-section that extends to a tangent ring terminating with a tab ring. The radiused cross-section and tangent ring assist providing a snug fit between the lid and the container. Despite being made from paperboard, the lid does not include one or more substantial crimps in the sealing ring. Having no substantial crimps, the lid fits onto the container and prevents fluid from leaking between the container's periphery and the lid.

摘要： An improved apparatus and method as provided for releasing sheet material press-formed in a die assembly between mating male and female dies from the die assembly. A first air supply system is provided for injecting air between the male die and sheet material in the die assembly to break any vacuum existing between the male die and the sheet material. Subsequently, a second air supply system is provided for injecting air between the female die and sheet material in the die assembly during ejection of a press-formed article from the female die so as to break any vacuum existing therebetween. A system is provided for discharging excess trim waste severed from the press-formed article and routing the trim waste toward a scrap collector while permitting the article to be routed in another direction toward an article collector.

摘要： An improved press produces oval blanks arranged in a "nested" pattern from a web of material. The press includes a cutting die plate having a plurality of oval-shaped discharge apertures, an inclined die shoe underneath the cutting die plate, and a punch for piercing a web supported on the cutting die plate to form blanks and then deposit the blanks into the inclined die shoe via the discharge apertures. Partitions divide the inclined die shoe into a plurality of blank transfer lanes. Each transfer lane connects one of the discharge apertures to a companion exit region. Guide rails are provided to guide blanks deposited into the transfer lanes toward the exit regions as the blanks fall under gravity through the inclined die shoe. A ramp is provided in selected transfer lanes to tilt the falling blanks therein relative to the path established by the guide rails to move those blanks laterally in the selected transfer lanes away from an adjacent transfer lane to avoid entanglement problems which could jam the die.

摘要： A die set is provided for forming a multi-compartmented tray from sheet material. The die set includes a female die assembly formed to include at least two mold cavities and a drawing surface bounding said mold cavities, a first compartment-former for pressing sheet material into a selected mold cavity to form a compartment therein, a second compartment-former for pressing sheet material into the remaining mold cavities to form compartments therein, and a draw ring for holding sheet material against the drawing surface during movement of the first and second compartment-formers into their respective mold cavities. The first compartment-former includes a first die for pre-forming the comparment, a second die for finish-forming the compartment, and a projection system for moving the first die relative to the second die in a direction toward the cavity to a leading position. A control system is also provided for disabling the projection system at a predetermined position of the first die in the cavity to permit relative movement between the first and second dies during finish-forming of the tray compartment. Such relative movement allows the first die to relinquish its leading position as the second die finish-forms the tray compartment to relieve pressure applied to sheet material at a predetermined stage of each molding cycle so that sheet material is able to flow within the selected mold cavity during the drawing process.

摘要： A press includes a frame, a flywheel, a motor for driving the flywheel, and a shaft. A clutch and brake assembly is provided which is actuable for engaging and disengaging the shaft to the flywheel. An eccentric is journaled upon the shaft and rotates therewith. The eccentric rotates in a block which is slidably mounted in a head to permit the block to move laterally within the head. The head is vertically movable in response to vertical movements of the block. The press also includes an upper die which is mounted on the head and a lower die which is resiliently supported upwardly on a base. Movement of the head engages and disengages the upper die and lower die. One embodiment of the press includes a second set of dies mounted to the head for cutting a continuous sheet of material into a predetermined shape.

摘要： A method and apparatus for forming a double-thickness bead in a flexible sheet stock article, such as a container or lid constructed from paper stock. The method includes holding a central region of the paper stock blank near its perimetral edge between cooperating dies, forming an axially extending flange in the blank between the held region and the edge, capturing the edge against radial movement in a groove provided in a ring movable relative to the dies, and moving the ring relative to the dies to form the double-thickness region in the blank between the held portion and edge. The apparatus includes the cooperating relatively movable dies, the movable ring and cooperating draw pads adjacent the ring. The draw pads are movable relative to the dies and ring and cooperate with the dies and ring to form a void into which the double-thickness region is formed. The configuration of the void controls the formation and configuration of the bead.

摘要： A deep compartment tray includes compartments separated by dividers which extend to between one-third and substantially the full depth of the tray. The tray is constructed from sheet material, such as polyester coated paper milk carton stock. The pre-forming step and the forming step for the tray are conducted by a first female die defining the tray cavities or compartments, and surrounded by a first draw pad region, and a second male die including bosses or land areas in the compartment regions and recesses where the tray dividers are to be formed. The male die includes a set of cavities, one in each of the tray compartment regions. The cavities slidably receive plungers or inserts which are movably mounted in the cavities and are spring-urged to their fully projected positions in the cavities. A second draw pad surrounds the male die, and is mounted for resistive movement relative to the male die.
