Abstract:
1. A method of wrapping a foil hood with an open end and a closed end around a load having a top and a plurality of vertical sides meeting at vertically extending corners, the method comprising the steps of sequentially; positioning a respective tensioning finger immediately adjacent each of the corners in an inner position above the load; gathering the hood into a plurality of vertically stacked folds and fitting the gathered hood over the fingers in the inner positions of the fingers with the open end of the hood open downward; spreading the fingers outward away from the load into outer positions spaced from the load and thereby transversely stretching the hood; and thereafter simultaneously moving the fingers downward along the load such that the closed end of the hood engages on the top of the load and the hood is pulled upward fold-by-fold off the fingers and continuously displacing the fingers inward toward each other into intermediate positions lying outward of the inner positions and inward of the outer positions.
