Abstract
Abstract A deflection yoke is mounted to a cathode ray tube by the use of two adhesives having different hardening rates. A first adhesive is applied between the yoke and the tube by a dispensing machine in a sufficient quantity to temporarily hold the yoke on the tube. A second adhesive having a hardening rate slower than the first adhesive is applied between the yoke and tube by the dispensing machine. The second adhesive purges the first adhesive from the dispensing machine. The quantities of the first and second adhesives are required to permanently mount the yoke to the tube. This arrangement may be used to assemble the yoke itself, as well as assembling the yoke and mounting it to a tube in the same operation.
