Abstract
There is provided a method for treating a surface which is to be bonded to another surface, the method comprising displacing a portion of the surface material to a position such that the displaced material, while remaining an integral part of the surface, forms a burr which is adapted to mechanically engage a flexible material placed adjacent thereto to thereby provide a mechanical interlocking action.
Claims4
A method of treating a first substrate which is to be bonded to a flexible material, comprising the steps of displacing a portion of the surface of the first substrate to a position such that the displaced material remains an integral part of the first substrate by forming a groove in the surface of the first substrate and allowing the material displaced from the groove to curl back onto itself, whereby said displaced material will mechanically engage a flexible material placed adjacent thereto to provide a mechanically interlocking action.
