Abstract
Abstract Method and apparatus for covering a product filled and open ended container body wherein an annular knife is carried by a stationary frame and a blanking die is also carried by the frame so that relative movement between the blanking die and the knife can compress an unblanked portion of a cover strip between the same to cut a cover member therefrom. A transfer device is also movably carried by the frame and has means for holding the cut cover member as the cover member is cut from the strip so that the transfer device can transfer the cut cover member from adjacent the knife to the open end of the container body. As the transfer device is disposing the cover member on the open end of the container body, a securing device tack seals part of the cover member to the open end of the container body. The transfer device has means for forming a slight depression in the cover member inboard of the open end of the container body for cover member expansion purposes as the transfer device places the cover member on the open end of the container body.
