Abstract
Disclosed is a method and apparatus for determining the quality of a spinweld bond produced on a single or multiple spindle production spinwelder and to a method and apparatus for alarming and/or ejecting products containing defective welds. The method and apparatus of the present invention utilizes a detector means to determine the condition of a tool or spindle (i.e., if it is still "live" rotating at a point when it should be at rest) and a timing means to actuate an indicator when a live tool is detected. The present invention also involves a means to detect a spinwelder with an actuated indicator and to eject the product thereon. The present invention also relates to a method and apparatus for automatically shutting down a spinwelder producing an excess of defective products.
