ABSTRACT:
A method is provided for bifolding articles on a high speed production line on which the articles are moved along a predetermined path. The method includes the use of a vacuum conveyor assembly to engage the leading end portion of an article and transport it in the machine direction, thereby potentially reducing the occurrence of undesirable misalignment of the article end edges during a bifolding process.
