Abstract
An apparatus for continuously and sequentially forming cylindrical bodies from flat sheet material includes a rotating mandrel and an array of forming belts spaced along the mandrel for receiving and winding either continuous ribbon or discrete blanks of composite material about the mandrel to form a cylindrical body such as for a container and passing the formed body along the mandrel to a heat sealing means to seal the overlapping edges of the material; the array of belts are disposed to partially surround and run in contact with the mandrel and a gap is provided in the spiral path of the belts to permit continuous feeding of sheet material to the mandrel to enable continuous operation of the forming apparatus.
