The first sack travelled badly.
Namm put it on the belt as an ordinary delivery would arrive, its loose end folded beneath one corner. The moving surface took it toward the scale. For half the distance it rode squarely. Then the folded corner caught against itself, the sack turned and its longest seam presented sideways to the receiving bench.
The second operator lifted it clear before it reached the end.
Iven watched from beside the drive.
“Again,” he said. “Same way.”
They sent three more through. Two travelled cleanly. The third turned like the first.
The belt itself tracked properly. The fault was the delivery angle. Namm moved the short table a little, tested the reach and asked for a low guide on the near side. It did not need to squeeze the sack straight. It needed to stop the first loose corner wandering while the moving belt took the weight.
They isolated the drive before fixing it.
