Peeling test device

Peeling test device for coupons derived from a vane, wherein the device is designed to test the resistance to peeling of said coupons each formed of a blade portion forming a support and an adhesive glued to a surface of the support and comprising

• a frame comprising a front roller and at least one guide roller, with parallel axes designed to maintain the coupon supported while guiding movement of the latter, tangentially to the rollers by rolling, during the peeling test,
• means of attachment designed to be attached with the adhesive,
• means of traction linked to the means of attachment, configured in order to pull the means of attachment in a pulling direction along an axis tangential to the front roller and designed to cause detachment of the adhesive from the surface of the support,
• means of measuring the force exerted by the means of traction in order to pull the means of attachment during peeling,
• wherein at least one of the rollers is translationally adjustable in relation to the other rollers in a direction perpendicular to the axes of the rollers and the guide rollers or each guide roller have/has an external local annular bearing surface with a linear appearance, in order to create a one-off connection with the coupon regardless of the angular position of the guide roller.
