A cloth web is prepared by providing a plastic cloth with a metallic casing layer on both sides thereof by vapor deposition, plasma spraying or cathode sputtering, and then galvanically coating the resultant material with a metal coating.

Method to produce a fabric strip, especially for a screen printing form, and fabric, especially screen printing fabric

The invention relates to a screen printing fabric made of self crossing plastic threads with an emulsion coating, wherein the plastic threads are coated with a vacuum metallized or sputtered encasing layer which is covered by an emulsion bearing metal coating produced by electroplating.

Screen printing form and flexible screen printing form accommodating device

In a process for the production of a screen printing form comprising a grid-like screen web with a coating of an emulsion, in particular a photosensitive emulsion, a screen web is partially provided with at least one coating area which is composed of a plurality of separately applied coating regions. Preferably the emulsion is applied in a plurality of mutually parallel adjacent coating strips of defined width by at least one nozzle.

Process for producing a screen printing form and screen printing fabric of a coated screen web

In an apparatus for stretching out a rectangular gauze material or the like cloth portion in a printing frame with tensioning devices which are arranged at the sides thereof and in which the cloth portion is fixed by a respective clamping mouth comprising clamping jaws (32, 36) which are movable relative to each other and which can be applied against each other on the closing travel of a closing lever under a pressing pressure and then the cloth portion is tensioned by a change in position of the clamping mouth units, caused by a piston/cylinder unit for a flow medium, in the pulling direction, when the clamping jaws (32, 36) are brought together the closing travel which is determined by the closing lever (50) is followed by a further closing travel and same is controlled by a piston rod. In addition the piston rod is to be part of the piston/cylinder unit for the pulling movement of the stretching device (16). Associated with the piston in the cylinder (20) are an open position of the clamping mouth (18), which is near the clamping jaws (32, 36), a central position with closed clamping jaws, and an adjoining stroke path for the stretching operation.
