Filter

Abstract

The invention relates to a filter with a gasket applied in line shape at an edge of the filter. The invention suggests to apply the gasket with a nozzle which facilitates a gasket that is thinner and/or whose protrusion beyond the filter is lower than this would be feasible for example through injection molding.

What is claimed is: 
     
         1 . A filter, comprising:
 a gasket,   wherein the gasket is applied to the filter through master forming without a molding tool.   
     
     
         2 . The filter according to  claim 1 , wherein the gasket is applied to the filter with a nozzle. 
     
     
         3 . The filter according to  claim 2 , wherein the nozzle is temperature controlled. 
     
     
         4 . The filter according to  claim 1 , wherein the gasket is printed onto the filter. 
     
     
         5 . The filter according to  claim 1 , wherein the filter includes a frame which is applied to the filter through master forming without a molding tool. 
     
     
         6 . The filter according to  claim 1 , wherein the gasket or a frame is applied at an edge of the filter and reaches about the edge of the filter. 
     
     
         7 . The filter according to  claim 1 ,
 wherein the filter contacts a support when the gasket or a frame is applied, and   wherein the support includes a recess in a portion of the gasket or of the frame.   
     
     
         8 . The filter according to  claim 1 , wherein the filter forms a carrier for a membrane. 
     
     
         9 . The filter according to  claim 1 , wherein the gasket or a frame have an extension above the filter of up to 500 μm. 
     
     
         10 . The filter according to  claim 1 , wherein the filter is subjected to a shape change in three dimensions. 
     
     
         11 . The filter according to  claim 1 ,
 wherein the filter includes at least one protrusion that is applied through master forming without a molding tool, and   wherein the protrusion is taller than the gasket.   
     
     
         12 . The filter according to  claim 1 , wherein the gasket and a frame is applied at an edge of the filter and reaches about the edge of the filter. 
     
     
         13 . The filter according to  claim 1 ,
 wherein the filter contacts a support when the gasket and a frame is applied, and   wherein the support includes a recess in a portion of the gasket and of the frame.   
     
     
         14 . The filter according to  claim 1 , wherein the gasket and a frame have an extension above the filter of up to 500 μm. 
     
     
         15 . The filter according to  claim 1 , wherein the gasket or a frame have an extension above the filter of up to 200 μm. 
     
     
         16 . The filter according to  claim 1 , wherein the gasket and a frame have an extension above the filter of up to 200 μm. 
     
     
         17 . The filter according to  claim 1 , wherein the gasket or a frame have an extension above the filter of up to 50 μm. 
     
     
         18 . The filter according to  claim 1 , wherein the gasket and a frame have an extension above the filter of up to 50 μm.
