| 摘要 |
The invention relates to a slotter wheel apparatus for slotting box blanks at selectively variable locations along the length of the blanks as the blanks are sequentially advanced along a path of travel. The apparatus comprises at least one elongated slotter blade (26) and means for selective shifting of said blade during rotation between an extended slotting position and a retracted, blank-clearing position. Said blade-shifting structure includes a shock absorbing assembly (27) for absorbing mechanical shocks incident to shifting of said blade (26) from said retracted position to said extended position. <IMAGE> |
