Abstract: A panel connection device is provided for attaching a panel of an inner grid to an outer frame for a lower blanking tool of a carton die cutting machine. The panel connection device includes a plate member defining inner and outer faces. The plate member has a recess formed therein for receiving a portion of the panel and a bore extending between the inner face and the outer face along an axis at an acute angle to the outer face. A clamping structure extends into the recess in the plate member for retaining a portion of the panel therein. A fastening element extends through the bore in the plate member into a corresponding slot in the outer frame to interconnect the plate member to the outer frame.
