Device for lubricating the surface of the tools of presses for the manufacture of components.

The invention relates to a device for lubricating the surface of the tools of presses for the production of liquid-effervescent, completely water-soluble Kompretten, which have a smooth and dense surface and are therefore packaged in tablet jars without special wrappings, e.g. made of paper can"

009817/0150

The production of such Kompretten made it necessary the Pressvorgo.ng in an environment with extremely low Humidity (* less than $ 20) and at a temperature below 25 C. In order to be able to maintain these low values, complicated and expensive systems had to be used for conditioning the air.

The present invention is now based on the object of creating a device that enables special conditioning systems in liquids effervescent Kompretten any composition with the help of eccentric or rotating presses, with a condition of the air of a relative humidity of not more than 40 i> and one Skin temperature not exceeding 30 G.

To achieve the stated object erfindungsgeiaäss is the proposal intended which serves for supplying the powdered mixture for the preparation of comprettes ücnuh for direct or indirect 'bciüt u; r \ _ir: "* ~ t press tools eijue or zv: -i ronmiermitxel-destruction.. . ü "tu :: _- ■■ ,. -_n 2UI, uorQiien case. deoter-travel; shoe a nin float executes (eccentric) satisfies a Zerstaubun _e si: bunting, which follows the course äes Scnuhs. For presses with turntable (rotary presses) it is necessary to provide two fixed lubricant atomizers, one of which is arranged in front of and the other after the feeding station of the powdery mixture.

Coverings that are commonly used for this purpose, such as Teflon, rubber, etc. produce brittle lompretten with wrinkled ones and non-uniform surface.

Genräss Pig. 4 the gate direction works as follows ι

In phase A, the soaking agent atomization chamber H is located above the pressing tool * P ¹ . The shoe 3 actuates the switch '<J _f, the valve E opens, whereupon the lubricant is atomized onto the surface of the lower preasting tool P ¹ produced Iomprette K is pushed away. Now the filling of the pressure chamber R located ^{above the pressure tool P 1 with the powder mixture takes place.} Then the shoe S is withdrawn and the chamber H reaches the Preeawerkeeug t * « ^x n of phase 0, the 8ohuto S actuates the switch G again and the lubricant is atomized onto the surface of the powder mixture in the pressure chamber B * In the fourth BUMit D the shoe S with the chamber I is completely withdrawn, the preaewool P is lowered and the Xoaprtttt K is established, whereupon the cycle is repeated.
