Abstract
The invention provides a machine for capping containers with closures made of heat shrinkable film and includes a film feeding mechanism, a film cutting mechanism, and a film shrinking head which is adapted to accommodate containers of different sizes. The film shrinking head comprises two elongate and opposed flexible heated members which are bowed away from one another so as to provide a space for introduction of a container and a sheet of heat shrinkable film that overlies the container, and means for drawing the two heated members and thereby the margins of the sheet of film tight against the rim of the container so as to cause the film to shrink and form a tight closure on the container.
