Open the CIPO recordAbstract From the Canadian patent
A cutting string having an edged and preferably a square, cross-sectional shape is used for cutting permanently elastic adhesive bonds, e.g. for taking out a vehicle window glued into a frame. Preferably, said cutting string is made of a massive material having a tensile strength of at least 1000 N/mm2. Particularly suitable are a V2A stainless steel alloys having a tensile strength of 1700 to 2000 N/mm2. Thus by the applica-, tion of a moderate tensile force very clean and smooth cut edges can be produced which are a good base for a new adhesive bonding.
