Methods for producing cylindrical flexographic printing elements, the cylindrical flexographic printing elements having a relief-forming layer, and the relief-forming layer being produced by successive application of a plurality of layers of a relief-forming material in liquid melt form, preferably of a photopolymerizable material in liquid melt form, to a rotating cylindrical sleeve in a continuous process.

Method for producing cylindrical flexo printing elements

A laminating process in which an adhesive composition which is freely flowing or can be rendered freely flowing is discharged from a coating appliance in the form of a substantially continuous or interrupted film, out of a slot nozzle with lateral film boundaries, and is applied and fixed to the surface of at least one web-type substrate, if applicable after being deposited on an advancing transfer substrate, such as a roller, and then transferred to the web-type substrate, and in which the film is guided outward to the substrate via the nozzle slot, clamped or hemmed in at its edges by the film boundary elements, heat is drawn off to the surrounding atmosphere via at least one heat exchange element provided along the film boundary elements.

Laminating process and apparatus for applying an adhesive-composition film to a web-like substrate

The invention relates to a device for applying adhesive threads to a substrate (). Said device comprises an rotatable application head () encompassing at least one adhesive discharge nozzle (A) located at a radial distance (b) from the axis of rotation (D) of the application head (), a shaft (B), and at least one adhesive supply duct (C) which extends from an adhesive supply unit () to the at least one adhesive discharge nozzle (A) via the shaft (B). A rotary drive unit () rotates the application head () about the shaft (B) thereof while an adhesive supply unit () and/or a valve assembly () control/s impingement of the adhesive supply duct (C) of the application head () with adhesive. The invention further relates to a method for applying adhesive threads to a substrate as well as products made therefrom.

Method and device for applying adhesive therads and points to a substrate, web of material comprising a fleece and a layer composed of adhesive threads, and products made therefrom

A glue coating apparatus is provided having a plurality of individual slit nozzles. Two faces are formed by an end face of a nozzle plate, in which feed channels open out, and by a clamping strip extending in front of the nozzle plate, these clamping a slit plate between them. The feed channels open into the regions of the slit plate which remain free between webs, so that the glue is channeled through the back of the slit plate. The webs and the individual glue streams are combined only immediately in front of an outflow point, to assure a uniform covering of the coating width, but prevent an overflow of glue from one slit nozzle into an adjacent one. The webs may also be tapered towards the outflow point, so that the individual glue streams can easily merge into one another. Separate glue pumps assigned to the individual slit nozzles can be provided in the form of a multiple pump, which can be designed as a gear pump, having a common central wheel and an appropriate number of planetary counter gear wheels arranged around the central wheel and generating cleanly separated feed streams.

Apparatus for the surface coating of glue

A glue coating apparatus is provided having a plurality of individual slit nozzles. Two faces are formed by an end face of a nozzle plate, in which feed channels open out, and by a clamping strip extending in front off the nozzle plate, these clamping a slit plate between them. The feed channels open into the regions of the slit plate which remain free between webs, so that the glue is channeled through the back of the slit plate. The webs and the individual glue streams are combined only immediately in front of an outflow point, to assure a uniform covering of the coating width, but prevent an overflow of glue from one slit nozzle into an adjacent one. The webs may also be tapered towards the outflow point, so that the individual glue streams can easily merge into one another. Separate glue pumps assigned to the individual slit nozzles can be provided in the form of a multiple pump, which can be designed as a gear pump, having a common central wheel and an appropriate number of planetary counter gear wheels arranged around the central wheel and generating cleanly separated feed streams.

Apparatus in which glue is applied to an endless thread by running the thread successively through the bore of a nozzle needle and a nozzle aperture and, when the nozzle needle is retracted from a valve seat, coating the thread with glue which has been forced out of a surrounding chamber. The thread, together with this coating, passes through the nozzle bore. As soon as the nozzle needle is advanced up against the valve seat in the nozzle element, the glue feed ceases and coating ends, so that the thread takes with it at most only very small quantities of glue remaining in the nozzle bore and an exact cutoff of the glue coating is obtained. When the glue is injected around the thread, that is, when the glue is brought together with the thread under a specific pressure exerted on all sides, it is possible to obtain a substantially uniform coating of the thread surface with glue which allows all improved bonding of the thread over its length to the sheet-like structure.
