The invention is concerned with the construction and
Arranged below the separating station is a pair of

According to the present invention there is provided 25 inner and outer chain guides 21 and 22, respectively, and
driven continuously by a pair of sprockets 23 through
an apparatus of the kind described comprising a blade

blade carrier 31 is mounted for pivotal movement rela~
tively to the support 29 about an axis normal to the path
of movement of the chains 19, each pair of opposed car
riers 31 being connected laterally by a blade-carrying bar
32 to which is secured a pair of laterally spaced blades 33.

By these means, the transfer blade moves over the
closed path at all times in planes parallel to itself so that,
with the stack or pack so arranged that the leading car
ton lies in the same plane at the separating station as that
taken up by the blades at that station, the blade is smooth
ly inserted into the leading carton which is then trans
ported by the blade to the intermediate station.
Conveniently, a plurality of supports, in each of which
is mounted a carrier as described above, are secured at
spaced intervals along an endless chain arranged adjacent
the stationary rack member, the chain being suitably
carrier 31 is a pinion 36, the axis of rotation of the pinion
being normal to that of pivotal movement of the carriers

ranged in continuous mesh with the various pinions 36.
With such construction the blades 33 are caused to remain
parallel to each other as the chains 19 are driven by the
sprockets 23 around the tracks formed by the chain guides
21 and 22.
Arranged adjacent one side of the pack of cartons 11
is a ?ap-de?ecting member 38 arranged to pass behind
