    Abstract: A method of making a hard multi-tubular structure which comprises; producing a flat hose fabric composed of a plurality of side-by-side abutting hoses, introducing uninflated foil tubes into each of the hoses of the fabric, the tubes being of substantially the same length as the length of the fabric, inflating the tubes for expanding the hoses into formed hollow sections, treating the fabric with a hardening material, and allowing a hardening of the hardening material and a setting of the fabric with the hoses in expanded condition. Therefollowing, the tubes are left after the setting of the hose fabric in the respective hollow sections free of any internal inflating pressure. Alternatively, the tubes may be withdrawn from the hollow sections after the setting.

    Abstract: An extrusion pelletizing process is disclosed wherein coolant is injected into the stream of thermoplastic material being extruded in such a fashion to interrupt the flow thereof and form discrete material lengths thereof as the material moves through the extrusion die and exits at the other end thereof in the form of pellets. The coolant is permitted to at least partially vaporize upon contact with the material stream and accordingly forms a solidified shell therearound including end portions of adjacent pellets so as to effectively separate such as they pass through the die. Such system enables the formation of discrete material lengths or pellets without the need of conventional cutting apparatus such as knives and the attendant support equipment necessary in their use.

    Abstract: In a multi-layer blow molded container having a joint portion at least in the bottom portion thereof, barrier characteristics to gases such as oxygen and water vapor and liquids such as water, solvents, aqueous ammonia and salt water and interlaminar strength characteristics such as interlaminar adhesion strength, peel strength and impact strength in the content-filled state can be highly improved by blow molding a parison of a laminate structure of two or more polymer layers in which the polymer composition is different with respect to the thickness direction of the container wall but substantially identical with respect to the plane direction and each of the polymer layers is continuous with respect to the plane direction, in such a manner that a tapered projection protruding outwardly in the thickness direction of the container wall is formed in the joint portion so that each of the polymer layers is substantially continuous in this joint portion. This improved container can easily be prepared according to the customary blow molding technique by using a pair of split molds having such a configuration that a tapered concave groove is formed in the section pinching off the parison when the molds are registered with each other.

    Abstract: For the blow molding of hollow articles there is provided a receiving station where parisons are prepared, a removing station where the blow molded articles are released from the mold and a depositing station where the articles are placed for transportation or treatment. A mold is movable between the receiving and the removing station and a gripper is movable between the removing and the depositing station. When the mold takes a parison in the receiving station, the gripper grasps a blow molded article in the removing station previously left there by the mold. When the mold opens and releases an article in the removing station, the gripper releases the previously grasped article in the deposition station.
