ABSTRACT:
A machine parts protecting system for protecting those parts of a machine that may be in close proximity to high temperature flames. This system is for a machine used for processing workpieces and has a plurality of workpiece holding members which are indexed in a stop-and-go fashion through a number of operating stations. The protecting system includes a photo-detector to detect that a workpiece is not being held by one of the workpiece holding members and to send a first signal to a memory circuit which retains that information until a predetermined time when the empty workpiece holding member arrives at an operating station with high temperature flames. At that time the memory circuit initiates a second signal opening a solenoid valve, thereby permitting an air jet to blow the high temperature flames away from the empty workpiece holding member.
