Abstract
Apparatus for seaming a container end E to an open end of a container body B, comprises a pad to support the container body, a seaming chuck to support the end E in place on the container body B and cooperating with the pad to hold the container body and end one against the other, and an annular seaming tool having two annular seaming profiles on its inner surface which surrounds the end for progressively folding peripheral portions of the container body and end together to form a seam. The annular seaming tool is mounted on a tool holder and means are provided for supporting and driving the tool holder in orbiting motion such that the axis of the seaming tool follows a circular path around the axis of the seaming chuck. The seaming tool is mounted on the apparatus for free rotation about its axis such that when the seaming profile engages the peripheral portions of the container end, it is free to roll around the end to form the seam progressively.
