Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. An apparatus for folding a web, comprising: a first conveyor, a second conveyor in close proximity to the first conveyor, wherein the first and second conveyors define an included angle of 15 to 40 degrees, a folding wheel aligned in close proximity to both the first and second conveyors, and a folding bar extending above and generally parallel with the second conveyor. 2. The apparatus of claim 1 further comprising a folding board proximate the second conveyor wherein the folding bar extends between the folding board and the second conveyor. 3. The apparatus of claim 1 wherein the folding wheel comprises a shaft and the folding bar is connected to the shaft and cantilevered over the second conveyor. 4. The apparatus of claim 3 wherein the folding bar is shaped like the number “7”. 5. The apparatus of claim 1 wherein at least one of the first and second conveyors is a vacuum conveyor.
