  • Method and an apparatus for measuring the bonding power of an adhesive material
    Patent number: 4232559
    Abstract: A method for measuring the bonding power of an adhesive material, particuly a sheet material comprising fibres impregnated with a glue. After having applied against the material the face of a totally reflecting prism the index of refraction of which is lower than that of the glue, a force is exerted which tends to bring apart from each other the prism and said material, the value of the force corresponding to the separation is determined and the quotient is made of said force by the value of the contact area measured at the moment of the separation from the light totally reflected by said face.
