Abstract:
A cut and score die apparatus is provided for progressively converting a sheet of material into blanks. The apparatus includes a punching section for punching scrap material from the sheet of material to define an array of interconnected blanks arranged in a grid of rows and columns on the sheet of material. A scoring section is provided for simultaneously scoring a first predetermined pattern on a trailing portion of a first row of blanks and a second predetermined pattern on the leading portion of a second, succeeding row of blanks on the sheet of material. A blanking section is also provided for piercing the sheet of material in a predetermined pattern to cut blanks from the sheet of material without producing any additional scrap material.
Abstract:
To produce a container with a rounded edge, the container blank is scored with several substantially parallel, laterally spaced score lines adjacent the intended location of the rounded edge. When the blank is bent, a portion of the total deflection is absorbed by each score line so that the resulting container edge is a gradual curve rather than a single sharp crease. The ends of each scored region may be left unscored to further smooth the ends of the rounded container edge. Methods and apparatus for forming the above-described blank are disclosed.
Abstract:
Apparatus for processing a sheet of material such as cardboard intended for making a folding box or case, comprises a stamping plate for carrying the sheet and co-operable with a tool. The stamping plate lies on a table plate of a frame structure which has holders for releasably carrying a form which extends parallel to the table plate, and at least one bridge assembly which extends movably above the table plate. A carriage is carried on the bridge assembly and moves transversely with respect to the direction of travel thereof. The carriage carries at least one vertically movable pressure member directed towards the table plate.
Abstract:
A method and apparatus for cutting and scoring plastic and paper box blanks is disclosed wherein a creaseless score line is formed using a score forming strip which is aligned on one die platen and is transferred to the cooperating die platen in mirror image alignment.
Abstract:
A wide-folding, linearly-hinged assembly of sheet members secured to each other in areas other than in the vicinity of the hinge is disclosed comprising: an inner sheet member having at least one ply and a female linear score on the inner side thereof; and an outer sheet member having at least one ply and at least four linear female scores arranged in pairs on opposed sides of said member, each of said outer scores bridging its paired inner score and said opposed pairs bridging said score of said inner sheet member.
Abstract:
An edge forming tool is pressed into a thermoplastic sheet which is supported on an anvil or counter tool. The edge forming tool is maintained at a temperature below the melting temperature of the thermoplastic sheet and a high frequency electric field is established between the edge forming tool and the counter tool. The high frequency electric field softens the thermoplastic sheet which is deformed by the edge forming tool. Thereafter, the softened and deformed portions of the thermoplastic sheet are allowed to cool and re-harden before the sheet is folded to form a bend therein.
Abstract:
A process and apparatus for cutting, creasing and/or embossing sheets of cardboard, paper of similar material is disclosed. The apparatus includes a tool plate or die having steps therein in the form of parting steps and ribs and/or grooves to form creases. A resilient elastic member is employed to press the cardboard web down against the various steps in the tool plate. The size and configuration of the steps and the tool plate causes severing or cutting of the cardboard or creasing or embossing. Apparatus for use with rotational as well as planar or reciprocating blanking machines and a variety of different tool plate constructions are disclosed. The process includes resilient urging of the sheet against the die piece with the elastic member causing deformation of the sheet to conform to the tool plate.
Abstract:
The punching and scoring tool produces scored punched parts from a material sheet and has a carrier board, which is provided on its underside with punching elements and a scoring plate, on the underside of which scoring projections are arranged. A punching/scoring plate, in which scoring grooves are formed under the scoring projections, is provided under the carrier board. Leveling bushes are provided in the carrier board and bear against the scoring plate to provide an accurate supporting plane for the scoring plate.
Abstract:
A kit for making boxes from paper card stock. The kit has a flat plate with a guide rail with a vertical edge projecting above the surface of the plate parallel to one edge of the plate. A scoring groove traverses the plate parallel to the vertical edge of the guide rail. One or more spacing strips, each having a vertical edge, may be placed between the vertical edge of the guide rail and the scoring groove to vary the depth of the box. The overall size or "footprint" of a box made in accordance with the invention is determined by the distance of the scoring groove from the nearest vertical edge and the size of the blank card stock employed. Two identical sized card stocks are used for each box. A slightly wider spacing strip is used to form the top than the spacing strip used to form the bottom of the box. This also makes the depth of the box bottom slightly greater than the box top. The kit includes a scoring plate, two sets of spacing strips and a scoring tool, and is used to fashion boxes in a variety of shapes and sizes. In another embodiment of the kit the scoring plate has guide rails and score lines on both sides, wherein the guide rail on one side is spaced slightly further away from the score line than on the other side to make the box bottom slightly smaller in size than the box top.
Abstract:
A bottom die for a stamping tool for producing cardboard blanks consists of a composite plate made from a support foil and a top layer consisting of phenol-resin bonded paper with a textile insert. Scoring grooves are milled into the top layer of phenol-resin bonded paper to serve as a counter contour of the top die of the stamping tool. The bottom die can be removably disposed on the bottom tool plate of a stamping machine by means of an adhesive layer which is self-adhesive on both sides. According to the invention, the scoring grooves are formed through the top resin bonded paper layer of the bottom die to the level of the flexible support foil, whereby the bottom die is given a relatively large degree of flexibility. Thus, a repeated use of the bottom die sheet is possible. In addition, a method for producing a bottom die for a stamping tool, employing the above-described die, is disclosed.
