摘要:
A web has a series of cut outs that define bridging portions therebetween. A method for folding the web includes providing the web to a first conveyor, folding the web about a folding wheel to define a folded edge that extends through the series of cut outs, transferring the web to a second conveyor having an included angle of 15 to 40 degrees in relation to the first conveyor, folding the web about a folding bar to maintain the folded edge, and spanning at least one cut out with the folding bar and contemporaneously contacting at least two bridge portions with the folding bar to maintain the folded edge of the web about the folding bar as the web passes the folding wheel edge.
