FOLDS FORMATION APPARATUS OF A FOLDED VESSEL

摘要

PURPOSE: A corrugation forming apparatus for a bellows-type container is provided to prevent one side of a container from becoming distorted by maintaining the internal pressure of the container using an air injection unit. CONSTITUTION: A corrugation forming apparatus for a bellows-type container comprises first and second molds(20,40) and forming blocks(30). The first mold comprises a mounting unit(21) and guide units. A container(V) having an inlet is fixed to the mounting unit. The guide units are formed around the mounting unit. The forming blocks are elastically moved along the guide units and are radially arranged on the first mold. Each forming block has a corrugation forming unit and an inclined plane(33). A pressing plane(41) of the second mold is inclinedly extended and touches the inclined plane of the forming blocks.
