Abstract: A device to stamp a number of creases into a material layer is provided, the device comprising a main roller body non-rotationally arranged on a rotating shaft and a number of holding elements sunk into the main roller body that serve to position and/or affix a first foil having a first creasing ridge on the circumferential surface of the main roller body, which is characterized in that a holding device is provided that can be angularly rotated relative to the longitudinal axis of the rotating shaft and that is configured to position and/or affix at least one additional second foil having a second creasing ridge.

Abstract: A method for specifying design rules for a manufacturing process includes providing a training set of 3D point meshes that represent an anatomical structure, for each 3D point mesh, finding groupings of points that define clusters for each shape class of the anatomical structure, calculating a prototype for each shape class cluster, and associating one or more manufacturing design rules with each shape class prototype. The method includes providing a new 3D point mesh that represents an anatomical structure, calculating a correspondence function that maps the new 3D point mesh to a candidate shape class prototype by minimizing a cost function, calculating a transformation that aligns points in the new 3D point mesh with points in the candidate shape class prototype, and using the rules associated with the shape class prototype, if the candidate shape class prototype is successfully aligned with the new 3D point mesh.

Abstract: A film cutter arrangement for a cutter roller is provided, and punched film cutters for producing cutouts have a cutting edge. The film cutter arrangement and the punched film cutters are attached to a lateral surface of the cutter roller magnetically and/or by vacuum. The punched film cutters can be variably positioned relative to the format film cutters in axial and circumferential directions of the cutter roller by adapter elements.

Abstract: The application relates to a device for quickly and precisely aligning and fixing foil blades on the body part of a blade roll. The rotary blade roll has a rotating shaft, at least one roll body part arranged with torsional strength on the rotating shaft, at least one foil blade supported by the roll body part, and a row of holding and positioning pins in the roll body part. Magnetic elements arranged in rows retain the foil blade flatly on the peripheral surface of the roll body part. The foil blade has a thin flexible magnetically permeable base plate and at least one sharp one-piece cutting edge of a predetermined cutting shape projecting from the base plate. The base plate has a leading edge, a trailing edge, two side edges opposing each other, and, in a front zone adjoining the leading edge, a plurality of slots aligned with the cutting edge.

Abstract: The invention relates to a knife roller with at least one film knife which s securable on a multi-part roller body, which comprises suction openings around its circumference, and connected thereto, suction channels extending in the lengthwise direction. The gist of the invention is that:a) suction openings are provided along several suction hole rows arranged next to one another in the circumferential direction,b) one suction channel is arranged to correspond with each suction hole row, andc) at least one suction air control channel and at least one adjustable suction air control disk are provided,d) by means of which the suction air control channel is selectively connectable with different suction channels, suction hole rows, and their suction openings.

Abstract: A rotary punch for punching envelope blanks from moving webs of paper or like or for making shaped cuts from prepared envelope blanks has a backup roll which bears on a cutter roll. The punch is characterized by the provision of intermediate bearings with an adjustable member therebetween. This precludes unwanted movements in the bearings between the two rolls due to varying cutting and out-of-balance forces, the adjustable member making it possible to correct the between-axes distance to suit cutter wear.

Abstract: A rotary punch for the production of pre-shaped outer and inner cuts on mng webs or individual blanks of paper or the like, and more particularly, for the preparation of envelopes, flat bags or the like, includes rotating cutting tools whose cutting edges describe an envelope cylinder and at the instant of cutting impinge on a stationary abutment aligned at a slight inclination to the axis of rotation of the tools and so clamped that the operative edge of the abutment is everywhere at the same radial distance from the axis of rotation. The punch has a holder for the abutment, which holder has a bed molded from a curable liquid, and a cutting ledge of circular cross-section which is secured in the bed.
