~_In accordance with the present'inve'ntion it is '

In general, the present‘ invention contemplates
the provision of a novel machine for forming a
lining and for inserting the lining into a carton in
a novel and superior manner and in which provi
sion is made for producing a novel and superior
‘35 bottom fold on the lining. Heretofore, in previous
carton lining machines, of which the applicant is
aware, the usual method of forming the bottom
fold of a lining has been to fold the extended side
portions of the lining blank against the ends of'av
440 forming block, leaving triangular‘ shaped tabs or
?aps extending outwardly from the bottom and
thereafter folding these triangular shaped ?aps
upwardly against the sides of the forming block.

details of construction and mode of operation of
