ABSTRACT:
The invention relates to a machine for working glass tubes, with several chucks circulating on a common axis and sweeping past several processing stations, there being mounted above each chuck a stepwise rotating magazine storing several glass tubes, each tube resting by its lower end on a non-rotating supporting plate which has a hole for the glass tubes to fall through for engagement by the chuck therebelow, the machine having a switch which causes the magazine to rotate, one step at a time, each step corresponding to the distance between two neighbouring tubes, in order to bring the next glass tube to the hole, and wherein between the hole of the supporting plate and the chuck therebelow there is a mobile arrestor blade which allows the magazine to rotate stepwise without a tube falling through the hole, until the chuck is empty, whereupon the blade can disengage so that it no longer blocks the hole.
