Abstract
A method and apparatus for packaging radially expansile articles by passing a succession of such articles in generally coaxially aligned engaging relation with each other through a tubular guide which retains the articles against expansion, sequentially discharging the end most article into a second tubular guide sized to permit limited radial expansion of the received article, extending an engaging member into the second guide to displace each successively discharged article away from the first guide to enable unobstructed discharge and expansion of the next end most article, and engaging the last discharged article to displace it and a predetermined number of previously discharged articles out of the second guide for bagging.
