Abstract
An apparatus for producing a resilient, readily stretchable tubular member for receiving and packaging articles therein, the apparatus including means for uniting two contiguous layers of flexible foam sheet material by fusibly uniting adjacent side edges of the two layers to form the same into a tubular member. Slitting means is provided for slitting the foam material in a pattern of spaced apart rows of spaced incisions, the rows being so arranged that the tube may be stretched radially to receive therein an article of greater cross sectional area than the initial internal cross sectional area of the tube.
