Abstract: In an arrangement for a position accurate joining of a first material web, which comprises elements in a section length separated by separating locations, with a second material web which is provided with marks arranged at a predetermined distance from each other corresponding to the section length—except for a possibly certain deviation, the arrangement includes a first device by which the two material webs are joined, a transport device by which the two material webs are moved stepwise by the predetermined distance, and a second device by which an element applied to the first material web when, after movement of the two material webs by a section length, the length of the material web between the first device and the second device corresponds to a predetermined multiple of the section length plus an offset, which is adjustable by an offset device, and a transport device by which the two material webs can be moved section-stepwise, wherein a sensor is provided by which the difference is determined and the of

Abstract: In an apparatus for the electrographic printing or copying using liquid coloring agents consisting of a carrier liquid and toner particles, including a latent image carrier and at least one supply element in the form of a slot-like supply nozzle via which the liquid toner is applied to the latent image carrier and a suction element by which excess liquid coloring agent is removed from the latent image carrier, a de-coupling channel is arranged between the suction element and the supply element.

Abstract: In an apparatus for imprinting an unmarked foil with images which are to be arranged within sections of the foil of a predetermined length L, including a printing device, a foil section transport device for moving the foil stepwise in sections of the length L, a cutting device for cutting the foil into the sections and a foil buffer arrangement accommodating a varying length of the foil between the printing device and the transport device, a foil motion sensor is arranged at the exit of the buffer arrangement for sensing the foil movement out of the buffer arrangement and controlling accordingly the speed of the printing device and a foil length sensor is arranged in the buffer arrangement and providing a print initiation signal when the foil length between the end of the foil in the cutting device and the printing device is a predetermined multiple of the foil section length L.

Abstract: In an apparatus for imprinting an unmarked endless foil with images which are to be arranged within sections of the foil of a predetermined length L including a printing device, a transport device with a foil section indicator provides a signal to a control unit to determine section limits and a buffer arrangement including a first foil movement sensor sensing the movement of the foil from the printer and a second foil movement sensor sensing the foil movement into the transport device is arranged between the printing device and the transport device and the control device to which the first and second foil movement sensors are connected compares the signals and supplies a printing initiation signal when the length of the endless foil between a section limit provided by the foil section indicator and the printing device is a predetermined multiple of the length of the section L.

Abstract: In an apparatus for accurately imprinting print images onto sections of a edetermined length of a continuous unmarked foil, wherein a printer is disposed at a distance from a foil section delivery device which receives from the printer unprinted foil along a predetermined path, a foil sensor is arranged along the foil path which sensor has an output connected to the printer for supplying to the printer a printing signal when the length of the foil between the delivery device and a point on the foil corresponding to the beginning of a section to be imprinted is a predetermined multiple of the length of the foil sections to be imprinted so as to initiate printing of the printer accurately within a section of the foil.
