Process and device for deposition of glue on a cellular surface

Abstract

A glue film ( 11 ) is placed on a cellular structure ( 10 ) in order to form a regular glue strip on the edges of the partitions of the cells of this cellular structure ( 10 ), and this glue film ( 11 ) is heated by a source ( 24 ) that emits radiation adapted to reactivity of the glue, to heat it only selectively. The glue thus creeps without significantly triggering polymerisation. The portion of the part located below the source is preferably kept approximately horizontal so that the glue strip is formed under the best possible conditions.

1 - 8 . (canceled)  
     
     
         9 . Device to obtain the formation of glue strips on the ends of the partitions of cells opening onto the surface of a cellular structure, this device comprising a source that may be placed facing the said surface, on which a glue film has been deposited in advance, the said source being capable of emitting radiation chosen to heat the glue only selectively, so that it creeps without significantly triggering its polymerisation.  
     
     
         10 . Device according to  claim 9 , also comprising a support on which the cellular structure will be added, the said structure being arranged such that the said surface is facing upwards.  
     
     
         11 . Device according to  claim 9 , in which the structure is arranged such that the partitions of the cells re approximately vertical.  
     
     
         12 . Device according to  claim 9 , in which the source is fixed and the support of the cellular structure moves to make the said surface move in front of the source with an approximately constant spacing.  
     
     
         13 . Device according to  claim 9 , in which the support is fixed and the source is capable of moving parallel to the said surface of the cellular structure.  
     
     
         14 . Device according to  claim 10 , applicable when the said surface is not plane, in which the support can be rotated and the source can be displaced facing the said surface among the trajectory and with an approximately constant spacing from it.  
     
     
         15 . Device according to  claim 12 , in which the source is capable of moving along a direction approximately normal to the said surface.  
     
     
         16 . Device according to  claim 12 , in which the upstream and downstream screens are associated with the source in order to limit dispersion of flux emitted by the source.  
     
     
         17 . Device according to  claim 10 , in which the support comprises at least one smooth side part without any cellular structure, on which a control glue film can be applied identical to the glue film placed on the said structure, temperature measurement means being placed facing the said smooth lateral part.  
     
     
         18 . Device according to  claim 17 , in which an adhesive tape resistant to temperature is placed on the smooth side part, on which the control glue film will be applied.
