Abstract
A seam adjuster for ensuring that a tight seam is formed between a can end and a can body. The seam tool () is mounted via bearing () on the seam lever (), the centre of the bearing being eccentric to its outside diameter. The bearing has an-external thread () which mates with a complementary worm mechanism (). By virtue of the eccentricity, rotation of the worm mechanism rotates the bearing and moves the seam tool radially for adjusting seam tightness. Seam tool height is set by a spacer () or shim which is readily interchangeable for varying the seam tool height without affecting seam tool tightness.
