Abstract
Tubular container bodies having a lap side seam, obtained by uniting a resin and an adhesive bondable therewith, are produced by applying the bonding resin to the limited lap area of body blanks moving in a continuous stream and applying heat to the limited lap area to cure the resin in less than one second; the resin may be so applied that the raw metal edge of the body blank is also coated. The resin may be subsequently reheated to the final state of cure in which it will bond to the tacky adhesive on the opposed lap margin of the body blank.
