摘要

A MEMBER OF SUPPORT BASE CARDBOARD (46) is mounted on a base cardboard moving (2) on a machine folder-gluer. The support member (46) is driven cyclically between an inoperative position on the cardboard base and a position connecting the upper surface of the base ADJACENT TO A dotted line (6) in the disc. The dotted line defines a flap (8) which is bent upwards when the support member is attached to the top BASE CARDBOARD surface to form a side wall of cardboard. The support member (46) PREVENTS THE FLAP (8) DURING sag bending operation, ESPECIALLY WHEN USED AS THE BASIS OF RECYCLED CARDBOARD CARTON.
