Removal method of material). This type of method is actually known. In the known method, the pattern material is completely dissolved and removed from the surface and openings of the stencil via a mixture of chemicals such as primarily formic acid and dichloromethate. If the stencil is shaped like a cylinder whose edge is connected to the edge of the fixed ring,
In known methods, the ring is generally first removed from the stencil via a suitable solvent before removing the pattern material.

とにより達成される。A disadvantage of the known method is that it is labor-intensive and takes a fairly long time. Furthermore, the solvent is contaminated by the adhesive and/or pattern material, which is generally a suitable lacquer. As a result, these drugs become less effective and after a while cannot be used any further due to solvent action. Therefore, the problem of disposal of contaminated chemicals arises. This is the most serious issue in recent times when it comes to the environment. Another disadvantage is that the chemicals used are often volatile. Consequently, special measures have to be taken with regard to personnel safety and environmental pollution. The aim of the invention is to eliminate the drawbacks of the known methods. The object of the invention is to provide a method of the type described in the preamble, in which the stencil is sprayed with a medium at high pressure locally onto the stencil and the stencil is moved with respect to the spray point in such a way that the entire part of the stencil covered by the pattern material is covered. This is achieved by moving.
パターン材料をステンシルからうまく除去するための環

い。その結果、噴霧されるべき表面はパターン材料の緩
んだ粒子を有しないままである。The environmentally favorable situation is reinforced by the fact that the removal medium can be water, preferably under a pressure of 150 to 300 bar. Particles of pattern material carried along with the water can be easily collected, for example through sedimentation. It is always preferred to spray the stencil from mutually opposing locations on each side of the stencil. As a result, the stencil is subjected to essentially the same mechanical stress on both sides. This will avoid damaging the stencil. Preferably, the stencil is held in an inclined position during spraying. As a result, the surface to be sprayed remains free of loose particles of pattern material.

体であり得る。The spray effect is pulsating (in a pulsatiB +
manner) can be increased by spraying. The stencil is preferably treated prior to spraying, such as through immersion in a weakening medium that weakens but does not essentially destroy the bond between the pattern material and the stencil. This weakening medium is then held essentially free of particles of pattern material. As a result, the weakening medium can be used for a longer time and the stencil can be cleaned more quickly and with relatively little mechanical stress during subsequent spraying with the removing medium. Such a weakening medium may be a liquid based on formic acid or lye.
