Abstract
A paper product traverses a straight line path through a folding apparatus defined by two folding stations that are mounted independently of one another. Each station includes supports, a central frame extending along the paper folding path, and belt arrangements for gripping, propelling and folding a laterally projecting portion of the paper. Each station is mounted for a lateral translation of the entire station perpendicular to the paper path. In the preferred form, this translation is accomplished with racks associated with each stand and pinions carried on a common drive shaft that engage the racks. Both stations also preferably include an arrangement for rotating the station as a whole in the horizontal plane to adjust the squareness of the fold.
