The claimed invention relates to a device in a guide bar (10) for a chain saw. The guide bar (10) comprises at least two layers (11, 12, 13) that are bounded by an adhesive material. To ensure that the layer of adhesive material gets the optimal thickness is one of the surfaces of the layers that will be bounded to each other provided with several protruding parts (17). The protruding parts (17) will generate a slot, with the same width as the height of the protruding parts, for the adhesive material when the layers are put together. This is important to ensure maximum strength in the bounding as well as a constant width of a groove (14) for the saw chain.

L'invention concerne un dispositif de guide-chaîne (10) destiné à une scie à chaîne. Le guide-chaîne (10) comprend au moins deux couches (11, 12, 13) liées ensemble au moyen d'un matériau adhésif. Dans le but de s'assurer que le matériau adhésif possède l'épaisseur optimale, l'une des surfaces des couches, destinée à être collée à l'autre, comporte plusieurs protubérances (17). Ces protubérances (17) génèrent une fente, de même largeur que la hauteur des protubérances, dans laquelle est logé le matériau adhésif lorsque les couches sont amenées l'une contre l'autre. Il est ainsi possible de s'assurer, ce qui est important, d'une force maximale de collage et d'une largeur constante de la rainure (14) destinée à recevoir la chaîne de la scie.
