‘ This invention relates to‘ packing machines for"
packeting cigarettes and like shaped articles and
has reference more particularly to the hopper
u device for accommodating the supply of .ciga
5 rettes or the like and to the means for controlling
the feed of the cigarettes from the hopper. [
In‘ such hoppers it is usual to provide some
means for controlling the ?ow of the cigarettes
I i from the body of the hopper to the discharge or
10 mouth whereby choking of the- mouth is pre
vented and ‘it is an object of the invention to
provide improved means for. this purpose.
A ‘further object is to provide improved means
for controlling the bulk‘ of the cigarettes in the
15‘ hopper while the predetermined number of ciga
rettes' is 'being'removed'by pusher of the wrap
