An article wrapping device feeds an article to be wrapped on a conveyor in a generally horizontal direction. A sheet of wrapping material is fed upward from beneath the conveyor to intersect the path of the article The sheet of wrapping material is maintained in a generally vertical orientation by a flow of forced air between the sheet of wrapping material and a generally vertical displaceable wall suspended alongside the path of the sheet of wrapping material. As the article intersects the sheet of wrapping material and the displaceable wall, the wall is displaced and forces a leading, edge of the sheet of wrapping material over a top side of the article.

Why it's free to use
- Filed February 12, 1993. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended February 12, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by February 12, 2015.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
