ABSTRACT:
Apparatus for spraying lubricant into closed moulds of a glass forming machine has the spray outlets on a carrier structure which is pivoted on the funnel arm shaft of the machine. For lubrication a pneumatic cylinder couples it to its support, fast with the funnel arm shaft so that the carrier and spray outlets are moved over the moulds. During a moulding cycle the carrier is held back inoperative by a spring so the funnels can be used normally. A method of moulding glass parisons includes selectively moving the carrier structure and spray outlets to spray lubricant at selected intervals to effect periodic lubrication cycles.
