  Note :

  First and second seaming operation rolls produce the double seam in two operations. The can and cover are clamped together between a base plate and a seaming chuck which is profiled to fit within the countersink portion of the cover. The can body and cover then rotate at high speed while the two seaming rolls are, in turn brought to bear with a steady pressure against the curl of the cover. The first-operation seaming roll has a seaming groove around its circumference, which forms the first-operation seam. The function of the second-operation seaming roll is to complete the seam formation and to compress the seam so that the books interlock tightly with the intervening spaces and crevices filled with the sealing compound originally placed inside the curl of the cover.
