Methods to control thermal variation during tube consumption in glass tube converting

Methods for producing articles from a glass tube include securing a working end of the glass tube in a glass tube holder of a converter having a plurality of processing stations including a heating station and a forming station. An initial length of the glass tube includes a plurality of serial segments, each of the plurality of serial segments corresponding to one article and having an article number. The methods include heating the working end of the glass tube in the heating station, adjusting an amount of heating of the glass tube in the heating station based on the article number at the working end of the glass tube, and forming a feature of the article in the forming station. Adjusting the amount of heating based on the article number reduces variation in tube temperature, article dimensions, or both, from one article number to the next article number.
