ABSTRACT:
The mouth end of a large filled sack is held taut and flat by holding means. Parallel folding bars extend downwardly from carriers like the prongs of a comb at both sides of the flattened mouth end. The carriers can be moved towards and away from each other, and raised and lowered, so that the folding bars gather or ruffle the mouth end to form a frill and are then withdrawn.
