A box-closing apparatus has a hanger link having one end pivoted about a fixed link axis on a stationary housing adjacent a station holding a box blank and another end defining a movable link axis. A two-arm main lever pivoted generally centrally at the movable link axis on the link has a pusher arm extending from the movable link axis and carrying a pusher block engageable with the flap of the box blank in the station and an actuating arm extending from the movable link axis and having an outer end. A drive lever pivoted at a fixed drive axis on the housing has an outer end pivoted at an outer drive axis on the outer end of the actuating arm of the main lever. The pusher block moves generally through a 0&#xb0;&#x2013;90&#xb0; sinusoidal trajectory to press an outer flap against a glue flap of the blank in the station.
