METHOD FOR THE INDUSTRIAL PRODUCTION OF A SLOT FOR ANCHORING A PLASTIC MOULDING RESIN

摘要

The invention relates to a method for the industrial production of an anchoring slot which is characterised in that it comprises the following steps: a support having a thickness (x + n) is selected; at least one anchoring groove is made along the entire length of the support (1) by creating an indent in the material, in particular by milling; a controlled rerolling operation is carried out, at least on the side of the face containing said groove (4), in such a way as to alter the thickness of the support (1) to thickness (X), which causes the concurrent collapse of the sides of said groove (4), thereby narrowing the entrance thereof in relation to the base to create the anchoring slot.
