An apparatus for adjusting seam tightness settings on a seamer for seaming a can end to a can body, the apparatus including: a seaming shank which is rotatable about its longitudinal axis; a seam lever mounted on the seaming shank; and at least one seam tool mounted on the seam lever for forming a first and/or second operation seam between a can end and can body flange; characterised in that: the seam tool is mounted via a bearing on the seam lever, the centre of the bearing being eccentric to its outside diameter; and characterised by an external thread on the bearing which mates with a complementary worm mechanism, whereby rotation of the worm mechanism rotates the bearing and moves the seam tool radially for adjusting seam tightness.
