Why High-Speed printing presses sometimes use gas flames to reduce electrical charge build up on the paper passing though the press?

Answer 1

This would appear to constitute a real and risky fire hazard. Paper catches fire at 45l F, the title of the Bradbury book (which dealt with book-burning by a perverse fire brigade that went about starting, rather than extinguishing, fires. It is conceivable that you may be thinking of Typsetting machines, such as the now-obsolete Linotype which used heat -in fact had a melting pot to recycle type metal, which was fire-formed in a sense, the machine set up the type, did not do the actual printing. these had thermostat controled gas flames and thus consumed ( In Brooklyn, where they were made, Brooklyn Union Gas, a subsidiary of better known Con Ed Power and Light.) There are and were cold-cast composing machines also, such as the Linoprinter by Matson and Elliott which sadly did not advance much from the toy stages. It should be mentioned that Matson& Elliott was the parent company of Mattel.
