2 Claims.
My invention relates to improvements in cap
form waxing devices for use in a paper bottle
capping machine, and the object of the inven
tion is to devise simple means for automatically
receiving the cap forms from the main feeding
and printing mechanism of the capping machine,
for feeding the received cap forms through a
wax bath, and for transferring the waxed cap
forms from the bath into receiving mechanism
10 for conveying them to the forming mechanism
performing the next operation of the capping
machine, and for ensuring the time of immer
sion in a wax bath maintained at constant level
and even temperature is suflicient for the proper
15 sterilization of the cap‘forms prior to contact
with the bottle.

mechanism and forming dies.
