| 4 | Apparatus for forming an outwardly-rolled lip on a cylindrical container body | US255259 | 1999-02-22 | US6120426A | 2000-09-19 | John Ellis Bacon |
| An apparatus is provided for forming an outwardly-rolled lip on an open end of a deformable cylindrical container body. The apparatus may include a mandrel having a generally cylindrical-shaped portion for movably supporting at least a portion of an interior surface of the container body. The apparatus further includes a lip-forming die assembly forming a part of the mandrel and having an annular cavity defining an open mouth portion and a closed bottom portion which defines a surface area extending generally radially outwardly of the mandrel outer surface and which is oriented with the open mouth portion generally transverse to an outer periphery of the container body and which faces the open end of the container body around the periphery. An axial forcing member contacts the other end of the container body for axially moving the container body along the outer surface of the mandrel and the container open end into and through the die assembly. The cavity bottom portion surface area of the lip-forming die assembly has a generally C-shaped cross-sectional contour in the direction of its outward extension which includes a combination of curved and straight sections positioned at predetermined radii and angles to a longitudinal axis of the container body, so that, when the outer periphery of the open end of the container body is forced into and through the die assembly to form the outwardly-rolled lip, the end of the container body will contact only a part of the bottom portion surface area of the die cavity to reduce frictional engagement and to minimize the force necessary to move the end of the container body through the die. | ||||||

| A strip of paperboard material having a thickness of 170 to 600 .mu.m and a multiplicity of fold lines formed widthwise thereof at a predetermined spacing and U-shaped in cross section is caused to travel as reeved around two prefolding rolls, 5 to 30 mm in diameter, from different directions at a contact angle of 40 to 270 degrees to bring the projecting side of the fold lines into contact with the peripheral suface of one of the rolls and the indented side of the fold lines with the peripheral surface of the other roll. This method imparts increased foldability to the fold lines. | ||||||
| 10 | Method of obtaining bend lines on packaging material | US757527 | 1991-09-11 | US5207632A | 1993-05-04 | John-Erik Brunlid |
| Bend lines on packaging material are obtained by creasing, which results in crease lines which are raised on one side of the material. According to the invention the raised parts of the crease lines are removed by mechanical processing, such as by milling, considerably increasing the crease lines' weakening effect on the packaging material and facilitating subsequent bending of the material. | ||||||
| 11 | Carton size modifier | US184943 | 1988-04-22 | US4825549A | 1989-05-02 | Harrison Huang |
| A carton size modifier comprising a tube, a supporting clamp installed on the tube and the structure for forming the hole line at the bottom end of the tube. The hole line forming structure comprised a rotating gear disk unit with a protection cover at its perimeter. The rotating gear disk unit is installed on the pipe seat having a handle. The top face of the pipe seat is cut at an angle to match with a pressing post having a complimentary angle at its lower end. One bolt threads the rotating gear disk unit, the pipe seat and pressing post, with its end fastened by a nut to avoid the fall-off of the pressing post. By puting the pressing post and the top end of the pipe seat into the tube. Then turning the bolt, the pressing post is pulled to make its outer wall supporting against the inner wall of the tube, thus its combination being completed. | ||||||
| 12 | Relatively rigid sheet plastic folding method, apparatus and article | US234907 | 1981-02-17 | US4386926A | 1983-06-07 | Joel Heller |
| A method, apparatus for forming, and article formed of folded, relatively rigid sheet plastic material (e.g. polyolefin is disclosed). A hinging membrane forming a flexible fold line provides stress-relief indentations in the sheet material so that the tensile and compressive strains normally produced when bending the sheet material at the folds are substantially relieved, thereby permitting efficient production of a variety of sheet plastic articles, such as folding containers and the like.Two embodiments of the invention are disclosed.In one embodiment, the stress-relief indentations are simultaneously formed on opposed surfaces of the sheet material at the desired fold line by an apparatus having an unheated die containing a scoring blade mounted for movement against the material to be scored, which is supported on a hard and polished platen, with the plastic sheet material arranged between the scoring blade and platen. The scoring blade and platen are brought to bear on the plastic sheet material disposed between them during the scoring operation to substantially reduce the material thickness along the fold line without substantial lateral displacement flow of the material away from the fold line. In this first embodiment, indentations are formed on opposed surfaces of the sheet material at the fold line which serves to relieve the tensile strains on the outer fold surface and compression strains on the inner fold surface normally produced when the material is bent about the fold line.According to a second embodiment, the desired hinging membrane is formed along the desired fold line by compressing the relatively rigid sheet material by means of a wedge shaped creasing blade dimensioned to compress the sheet material along the desired line of folding to between 10% and 75% of its nominal thickness and flaring from the compressed surface to the material surface. | ||||||

| The invention relates to a method and an apparatus for deep-drawing a tray (1) from a blank of sheet material (2). The blank is provided with score lines, which determine the location of wrinkles formed in the process. The apparatus comprises a female moulding tool (3), which comprises a cavity (7) for forming the tray bot-tom outwardly, a male moulding tool (4), which comprises a plunger (11) for form-ing the tray bottom inwardly, the plunger being movable with respect to the cavity for forming the tray, and clamps (6, 15) with an interface for holding the sheet ma-terial and forming a tray rim flange. According to the invention by laterally distanc-ing at least one of the moulding tools (3, 4) from the sheet material leeway is pro-vided for free forming so that wrinkling of the tray side walls is achieved in a con-trolled manner. Spacer plates (13) may be positioned behind the plunger (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) therebelow, or screw means may be provided for adjusting the distance of the bottom of the cavi-ty from the clamp interface and thereby varying the depth of the tray. | ||||||
