A FLARE JAW MECHANISM FOR STEM MACHINE FOR MAKING LAMPS, AND A STEM MACHINE THEROF.

摘要

An improved flare jaw mechanism for a stem machine, for gripping a flare, said mechanism comprises: a first jaw being a fixed straight jaw having a straight inner surface to mate with said flare, and having a fixation point; and a second jaw being a V-jaw having a recess such that inclined surfaces which form the arms of said V-jaw mate with said flare said second jaw characterised by a pair of flare centering screws orthogonally passing through each of said arms of said V-jaw such that said screws are adapted to move radially in and out of said jaw so as to obtain accurate centering whilst gripping said flare from a direction which is angularly displaced with respect to said first jaw gripping. A stem machine with said flare jaw mechanism is thus provided.
