Method and apparatus for filling and closing large sacks |
摘要 |
Sacks are successively filled and closed in an automatic process by suspending each sack from near the mouth and spreading the side walls apart, filling the sack, allowing it to settle on a support while keeping the side walls taut, bringing the side walls together near the mouth and folding them over onto themselves, welding a closure tape over the folded-over portion and the adjoining unfolded portion of the sack, crimping the unfilled upper part of the sack and gathering it to form a frill, and applying a clamping ring beneath the frill.
