ABSTRACT:
A closure assembly especially adapted for use with the mould of cheese block forming machines, includes structure defining an opening and a closure member mounted to the structure for movement to and from a position in which it closes the opening. Co-operable locking means on the structure and closure member include a first element fixedly mounted to a shaft for rotation with the shaft, which is in turn rotatably supported on the closure member, and a second element defining a seat for the first element in a particular rotational position of the shaft. Seated engagement between the elements at this position physically locks the closure member in its closed position. Drive means coupled between the structure and the shaft is reversibly actuable to execute a first motion in which it drives the closure member from an open condition to its closed condition and then a succeeding second motion in which it causes rotation of said shaft to effect seated engagement of the co-operating locking means.
