Abstract:
A method of making a part from a first and second member, comprising the steps of:a) mixing together in a container a mixture of an adhesive and a plurality of non-compressible beads;b) pumping the mixture from the container through application equipment having at least one valve onto a surface of the first member adjacent an edge thereof;c) placing an edge of the second member onto the surface of the first member such that the mixture is sandwiched therebetween, the concentration of beads in the mixture being in the range of up to 20 percent of the mixture; andd) bending and pressing the edge of the first member over the edge of the second member to form a hem-flanged joint;wherein the beads provide a substantially uniform gap between the first and second member to prevent a substantial amount of adhesive from being squeezed from the joint so that an effective amount of the adhesive remains present within the joint to form a strong bond therebetween to prevent separation of the members.
