Abstract: A self-adjusting clamp mechanism prevents sheets from migrating back during the compiling of sheets in a stacker. The mechanism consists of a spring-loaded ball bearing in a converging track placed just before a registration wall. The sheets would be scuffed under the ball bearing and against the registration wall. The track converges away from the registration wall such that: it allows sheets to enter freely against the registration wall; exerts little resistance for side tamping; and prevents the sheets from moving away from the registration wall as the ball bearing is driven tighter into the converging track.
