As a pair of rotary shafts rotate, tool heads mounted thereon and each carrying a tool rotate, so that the tools work the web of corrugated fiberboard fed between them as required. When a transfer unit is operated with the tool head supporting plate coupled with the position adjusting member carrying a tool head, they move together axially along the rotary shafts, so that a pair of the tools will be moved simultaneously to a desired position. | |
