Abstract

The invention relates to a method and an apparatus for positioning a feeder needle, and to a production line for optical components, in which a feeder needle of an apparatus for portioning fluid material, preferably softened glass, in particular of a needle feeder, has its position relative to a seat for the feeder needle recorded by means of a force-measuring device, and to further apparatuses which realize this method and to objects produced by the process.
