Abstract: A calibration procedure is carried out for determining the displacement distance from a reference point to the center of the blade in a web cutter in a mail inserter. A photosensor is placed near the paper plane of the web cutter to sense a web edge at the reference point downstream or upstream from the blade. At the start of the calibration procedure, the blade is caused to cut the web for providing a web edge. The web edge is moved in a backward and forward motion over the photosensor a few times for determining the theoretical center position of the photosensor relative to the position where the web is cut by the blade. By taking into account the chip-out width, the displacement distance from the center of the photosensor to the center of the chip out blade can be determined.

Abstract: An improved apparatus and method for cutting and processing sheets from a web of printed material comprising first and second side-by-side portions of sheets along a length of the web. A first transport is arranged to transport the web in a first horizontal direction. A web splitter splits portions of the web as they are transported on the first transport. An extended path transport, in line with the first transport, transports the second portion of the web in an extended path. A direct path transport, in line with the first transport, transports the first portion of the web on a more direct path. As a result of these different paths sheets within the first and second web portions are re-sequenced in a manner suitable for processing by downstream modules, such as a right angle turn module.
