Abstract
An apparatus for forming a web of wrapping material into a tubular configuration is disclosed. The apparatus is basically composed of a highly flexible, elongated elastic sheet material secured at one end, the sheet material extending obliquely upwardly and then returning to form a loop, and an actuator mechanically connected to the other end of the sheet material, the actuator being operable to advance and retract the sheet material so as to contract and expand the loop formed by the sheet material.
