  • Method for gluing plastic objects with a hot-melt adhesive
    Patent number: 6627036
    Abstract: In a method for bonding plastic objects together by means of a hot-melt type of adhesive, in addition to or during the heating and addition of a plasticizer-resistant hot-melt adhesive, at least one of the objects to be bonded, is heated up in the area to be bonded beyond the melting temperature of the material of which it is made. The method is particularly advantageous for the joining together of multi-layered plastic pipes. The result is the generation of a method for bonding objects by means of a hot-melt type of adhesive that can also be applied with materials for which it was hitherto impossible to apply hot-melt adhesion.
