Abstract: An apparatus and method is disclosed for ejecting workpieces from machines, especially lidded containers from lid seamers, that have a forming station including a chuck element and a forming roller and that have a positioning mechanism that advances to move the workpiece into engagement with the forming station. The apparatus and method utilize a resilient element to exert an ejecting force. The resilient element is disposed on the chuck element in a manner so that engagement of the workpiece operates to compress, either by compression or deflection, the resilient element so that it exerts a restorative force that ejects the workpiece. Where a lid seamer is sued with a pull opener (e.g., pop top) lid, the contact with the resilient member occurs a location spaced from the opener and its connecting elements. The resilient element is preferably cup-shaped having a central panel and a longitudinally and radially outwardly projecting lip.
