This invention relates to tube assembly devices
and more particularly to a tube telescoping ma
chine, although certain features thereof may be
employed with equal advantage for other pur
‘ taken substantially along line VII—VII of Figure

Figure 8 is a fragmentary sectional view of the
poses.
It contemplates more especially the provision
of a machine for continuously assembling and
?tting tubes that are generally adapted for tele
scopic association for any desired purpose such
as applicators for catamenial devices described
and claimed in United States Letters Patent No.
2,024,218. This application is a division of my
copending application Serial No. 463,091 ?led
October 23, 1942, which has matured into Patent
No. 2,391,915, January 1, 1946.
One object of the present invention is to simpli
fy the construction and improve the operation of
devices of the character mentioned.
‘Another object is to provide improved means
for continuously assembling and ?tting tubes
sized for telescopic association to comprise a unit.
Still another object is to provide continuous
power means for automatically ?tting tubes sized
for telescopic association.
A further object is to provide improved means
for combining and frictionally ?tting telescopic
tubes of paper or other deformable substances
without impairment thereto.
A still further object is‘to provide improved
tube telescoping guide taken substantially along
line VIII-VIII of Figure 3 showing the tubes
about to be telescoped in each other.
