ABSTRACT:
A liner of flexible sheet material is placed on a table on which a longitnally-slotted cylindrical tube and a cylindrical container of slightly larger inner diameter are mounted in axial alignment, and the liner is started into the tube slot. The liner is drawn into the tube and formed into a coil therein by the force of a tangential air jet perpendicular to the slot. Then, the coiled liner is moved axially from the tube into the container by a second tangential air jet directed at an angle of about 45.degree. to the axis. The resilience of the coiled liner causes it to spring outward to snugly fit within the container.
