Abstract
An apparatus and method for the manufacture of closures, which are used for closing containers such as glass jars for food. During manufacture, it is essential that sealing compound is prevented from ingress onto the centre of the closure as such ingress could lead to possible contamination of the food. The sealing apparatus and, in particular, the sealing punch of the present invention have features which achieve this control.
