A JIG FOR MANUFACTURING A CONTAINER WITH A ROLLED FREE EDGE
The present disclosure envisages a jig (100) for manufacturing a container with a rolled free edge. The jig (100) comprises a container fixture (110) and a rolling die (150). The container fixture (110) comprises a first set of split jaws (125) abutting an operative outer side of the container near the free edge of the container, and arranged to slide along the outer sides of the container, thereby supporting the outer sides during the rolling operation. The rolling die (150) of one embodiment comprises a second set of split jaws (165) having a rounded groove (155), the split jaws of said second set of split jaws are arranged to contract during the rolling operation.
Rim flattener apparatus and method
An apparatus for forming an upper edge of a paperboard container includes a pocket including a shell having a cavity with a mouth configured to receive the container along an axis such that the rim extends beyond the mouth. A workstation includes a forming member having a first forming surface which is actuatable toward the axis from a retracted position spaced from the rim to an extended position lying adjacent an upper end of the rim, and a forming segment having a second forming surface which is actuatable along the axis and the forming member in response to axial movement thereof such that the second forming surface is positioned spaced from a lower end of the rim. The second forming surface is actuatable along the axis towards the first forming surface to form the rim therebetween.
Apparatus and method for producing containers from paper material or paper-like material, and container
An apparatus for producing containers from paper or paper-like material. The container has a lateral surface made of a wound sheet-like segment, of which segment edges arranged on longitudinal sides overlap and form a region of overlap, and a pan-like termination element. The lateral surface and the termination element are connected to one another in an essentially liquid-tight manner by a skirt, and at least one pressing ram is provided for pressing and sealing the skirt, the pressing ram subjecting the skirt to essentially radially directed pressure. The pressing ram has a radially projecting protrusion in a portion provided for the purpose of acting on a boundary portion of the region of overlap of the lateral surface of the skirt.
Method for three-dimensional shaping of material
A method for the three-dimensional shaping of flat material made from in particular, natural fibers, such as for example, paper or cardboard, using a deep-drawing piston and a die, through which or into which the material is drawn. The diameter of the deep-drawing piston plus the material thickness of the deep-drawn material corresponds at least approximately to the diameter of the die.
Creasing device for forming creases in paper and bookbinding articles, and machine comprising such device
A creasing device includes a frame with a substantially horizontal support surface for supporting an article to be creased; a movable tool; and a stationary tool, the latter comprising a stationary member and at least one displaceable member whose height relative to the stationary member can be adjusted. A first actuator moves the movable tool toward the stationary tool and interacts with opposite faces of the article, and a second actuator translates the displaceable member between a first end position in which interacts with the movable tool and a second end position in which it cannot interact with the movable tool. Guide means associated with the stationary tool guides the displaceable member between the first end position and the second end position. The guide means are have a curvilinear path contained in a plane substantially perpendicular to the support surface.
Method and apparatus for curling an article
An apparatus for forming a curl on an article includes a first forming tooling having a first set of rollers mounted on a common head. The first set of rollers has a respective groove having a first groove radius. The apparatus further includes a first rotating turret configured to load the article into the first forming tooling. The apparatus further includes a second forming tooling having a second set of rollers mounted on a common head. The second set of rollers has a respective groove having a second groove radius. The second groove radius is larger than the first groove radius. The apparatus further includes a second rotating turret configured to load the article into the second forming tooling. The apparatus further includes a first transfer star wheel configured to transfer the article from the first rotating turret to the second rotating turret.
CREASING DEVICE FOR FORMING CREASES IN PAPER AND BOOKBINDING ARTICLES, AND MACHINE COMPRISING SUCH DEVICE
A creasing device includes a frame with a substantially horizontal support surface for supporting an article to be creased; a movable tool; and a stationary tool, the latter comprising a stationary member and at least one displaceable member whose height relative to the stationary member can be adjusted. A first actuator moves the movable tool toward the stationary tool and interacts with opposite faces of the article, and a second actuator translates the displaceable member between a first end position in which interacts with the movable tool and a second end position in which it cannot interact with the movable tool. Guide means associated with the stationary tool guides the displaceable member between the first end position and the second end position. The guide means are have a curvilinear path contained in a plane substantially perpendicular to the support surface.
METHOD FOR THREE-DIMENSIONAL SHAPING OF MATERIAL
A method for the three-dimensional shaping of flat material made from in particular, natural fibers, such as for example, paper or cardboard, using a deep-drawing piston and a die, through which or into which the material is drawn. The diameter of the deep-drawing piston plus the material thickness of the deep-drawn material corresponds at least approximately to the diameter of the die.
APPARATUS AND METHOD FOR PRODUCING CONTAINERS FROM PAPER MATERIAL OR PAPER-LIKE MATERIAL, AND CONTAINER
