Abstract

Die Erfindung betrifft die Verwendung von mit geeigneten Bearbeitungskörpern (9) gefüllten Gleitschleifvibratoren zur glättenden Bearbeitung von Holzteilen, insbesondere Möbelteilen (12), zwischen deren Grundierung und Lackierung.The invention relates to the use of surface finishing vibrators filled with suitable processing bodies (9) for smooth processing of wooden parts, in particular furniture parts (12), between their priming and painting.

Claims

1 2 uniform surface treatment is guaranteed is ι patent claims: and the shadows that often occur after later painting with clumsy handwork.

1. The use of pieces of soft wood as sanding does not occur.

body during vibratory slide grinding of primer 5 This task is solved by using

th wooden parts, especially furniture parts, before the softwood pieces as grinding tools in Vibralions-

Paint. slide grinding of the wooden parts mentioned at the beginning.

2. According to claim 1 used soft wood piece- The main advantage of the invention is therein too ke, characterized in that they see the shape kanti- that through the use of soft wood pieces Wooden pins of size 4 mm χ 4 mm χ 30 mm are used as grinding tools to work on the work gap sit. is carried out so gently that the primer is also applied

3. According to claim 1 or 2 used soft area of the edges of the workpieces is not removed, pieces of wood, characterized in that the hardness limited machining of the wooden parts degree of the softwood pieces an average of approx 95-100 ° Shore A has 15 upward-facing primer, creating a rough

4. According to one of claims 1 to 3, use the surface leading wood fibers,, ndem the te pieces of softwood, characterized in that protruding fiber ends are essentially turned over they are resin free. or canceled.

This processing can only be carried out with soft

20 pieces of wood. Additional abrasive particles, such as those found on the stand

the technology, however, are not required. Tests have shown that depending on the size of the

The invention relates to the smooth processing of furniture parts with a processing time of approx.

5 min. Primed Wooden parts, especially furniture parts, are sufficient to achieve excellent surface smoothing painting by vibratory slide grinding. Achieve 25.

Since after the priming of wooden furniture parts According to the invention, it is advantageous if the ver

see the fibers on the wood surface vertically after turned pieces of softwood align the shape of angular wooden pins and lead to a rough surface that is 4 mm 4 mm 30 mm in size. The intermediate lacquer sanding aimed at the wood surfaces is characterized by the roughness exposed to the following lacquer - good, constant quality. All areas of the OB to kiervorgang to remove. This is usually done on the surface of textured furniture- % iii manual work, since the design of the surfaces of parts are recorded with certainty. U

especially structured furniture parts and the

due to the necessary sensitive and careful degree of the softwood pieces a mean value of approx. Sj action, the use of machines is not permitted. 35 has 95-100 ° Shore A and the pieces of softwood.
