摘要:
Printing plates for all-over printing of large areas by the intaglio printing process, a method for producing the printing plates and data carriers, in particular bank notes, with large-area printed images produced by the intaglio printing process area proposed. Flawless inking is ensured by providing partitions in the engraving of the printing plate which rise up vertically from the base of the engraved area and have at least a height of 50% of the engraving depth. The partitions largely prevent ink from being wiped out of the engraved areas when ink is wiped off the printing plate surface. This permits a large printed area to be covered all over with ink layers on a data carrier. By special arrangement and design of the partitions one can also produce fine structures in the printing area which area recognizable only with magnifying aids depending on the selected distances between the partitions.

摘要:
The invention relates to a filling machine for stuffing of a plastically deformable mass such as baked sausage material using a filling pump which, per a unit angular displacement conveys equal amount of filling masses and is coupled to common drive shaft by two gear trains, at least one of which has an intermittently-driven output member on a periodically variable transmission ratio. The machine includes a first differential gear train with three coupling connections, one each of the latter coupling connections are connected to the first coupling connection of one of the gear trains and the common drive shaft respectively, while the second coupling connections of the two gear trains are couplable to each other.

Methodwise this disclosure relates to the manufacture of workpieces having polygonal inner or outer contours based upon radii of predetermined inner and outer circles with n being the number of angles of the desired polygon, the method including the steps of rotating a workpiece about its axis, moving the tool along an ellipsoidal path while in contact with the rotating workpiece with tool travel along the ellipsoidal path having velocity varying generally sinusoidally as a function of tool location, said ellipsoidal paht is radially offset from the workpiece axis of rotation and its width generally corresponds to the difference between said inner and outer radii, and rotating the workpiece about its axis for a duration of time longer than the duration of movement of the tool along the ellipsoidal path by said factor n.

摘要:
A data carrier with an optically variable structure is described having an embossed screen which is combined with a coating contrasting with the surface of the data carrier in such a way that different optically variable effects occur at different angles. Embossed screen and/or coating are executed in such a way that especially striking or additional effects occur which are suitable for determining the authenticity of the data carrier but cannot be reproduced, or reproduced true to the original, with the help of copying machines.
摘要:
A strand of sausage filling is pushed stepwise through a tube over which is fitted an empty sausage casing such that as the strand emerges stepwise from the downstream end of the tube it fills the casing. The filled casing is gripped between a pair of conveyor belts whose spacing is predetermined and is pulled away from the tube stepwise synchronously with the advance of the strand in the tube. Between advance steps of the strand and of the filled casing the tube is rotated such that the casing is twisted to form individual sausage links. The instantaneous speed at which the conveyor pulls the filled casing from the tube is proportional to the instantaneous speed of the strand in the tube. The spacing between the conveyor belts may also be varied automatically as a function of the overall conveyor operating speed.
