摘要
A packaging apparatus has a lift mechanism to lower and raise a tool, such as a formation box that functions to form cavities in a web of flexible material. The lift mechanism has a series of arms, supported by belt driven carriages, which move in tandem to raise and lower the formation box. The arms are arranged into two sets such that when the arms within each set are moved closer to one another, the formation box is raised, and when the arms within each set are moved away from one another, the formation box is lowered. The common driving of all arms by a belt allows the indexing of the formation box to be well controlled.
