the article in the` manner shown in Fig. 8 the
operator of the machine folds the two ends of
extension shown at 95 and 96 inwardly against
'the end of the article and places the article and 15
wrapper on the support C which, as above ex
plained, is disposed below Ithe level of the supports
A and B. As the package is placed on the sup.
port C the bottom end fold 91 will be folded up
wardly in the manner shown in Fig. 9 against the
rear end of the article.
This leaves the upper
end fold 98 projecting rearwardly substantially
in a'linement with the upper surface of the article
and wrapper. The package is then engaged on
the support C by one of a series of feeding mem

'I'he operator of the machine then. by manual v
operation, folds the end'tucks 95 and 96 inwardly
