Apparatus and method for manufacturing ovenable paperboard articles. |
摘要 |
A method and apparatus are disclosed for imparting a desired shape to a paperboard blank. The blank is formed between two dies for a sufficient length of time and with sufficient force to set the form, while moving the dies in tandem along a predetermined portion of a reciprocation path. Because the formed blank remains in dwell while the dies are moving in tandem, it is not necessary to hold the dies stationary to ensure permanent formation of the blank. This allows greater production speeds. |
