A blank for use with an apparatus for continuously and sequentially forming cylindrical bodies with the blanks which are each made from a fiber board material which is rectangular in shape and has a leading and trailing edge, both of which are coated with a heat activatable adhesive so that when the blank is heated and immediately passed to a formal mandrel to be formed into a cylindrical body, the heat activated adhesive will secure the blank in a cylindrical form as well as seal the leading and trailing edges.

Method and machine for convolute or spiral winding of composite materials

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.

A container is formed by providing a composite wall with reinforcing strips which surround the exterior of the wall at its opposite ends. The container is capped by end closures the edges of which engage the reinforcing strips to deform the strips to both overlap the closure edges and compress the container wall between the strips and the closures.
