Abstract
A seal between an ingot mould and a base plate or between a head-box and an ingot mould is formed from a pack of flat, flexible strips, for example, of cardboard or aluminium interlinked at spaced intervals along the strips. The joints between any one strip and an adjacent strip next to one face thereof are staggered in relation to the joints between the one strip and the adjacent strip next to the other face thereof. The pack is expanded lengthwise to separate the strips where they are unjoined and form generally hexagon shaped cells and is then placed on the base plate with the longitudinal edges of the strips of the pack on the base plate. The expanded pack is arranged lengthwise into a closed figure corresponding to the shape of the ingot mould. The ingot mould is then placed on top of the expanded pack which is crushed between the ingot mould and the base plate to form the required seal. A head-box seal is similarly made between the top face of the ingot mould and the head-box.
