ABSTRACT:
Apparatus for automatically removing stuck and down ware from an automatic glassware ware forming machine conveyor produces a first signal for each item of normal ware, stuck ware and down ware which is conveyed past an inspection location. Each of the first signals has a duration corresponding to the time required for passage of the corresponding item past the inspection location. The apparatus also produces a second signal simultaneously with the production of each of the first signals, the second signals having a predetermined duration corresponding to the time required for a normal upright and spaced item of ware to be conveyed past the inspection location. The generation of a reject signal during the duration of each of the second signals is inhibited and a reject signal is generated if a first signal is present after the termination of the corresponding second signal, which actuates a signal responsive automatic ware removal mechanism.
