method for controlling pre forms a multiple side-by-side ordered broken glasmaschine stations

摘要

A control method for initiating the preforming stage in adjacent stations of a glass machine, comprises: (i) making the glass droplet falling time, between cutting the glass strand and droplet arrival in the preforming mould, dependent on the arrangement of the station carrying the preform, in the glass machine; (ii) an allocated delay for each station, corresponding with their respective positions, and also appropriate to initiation of the forming process. Preferably, the delays allocated are based progressively from a zero value set from the droplet fall time to the central station(s) of the glass machine.
