Abstract
A compact interstacking web deflector for causing a split paper web to overlap one side of the web over the other. The web deflector includes a triangular support plate over which the split web flows. The triangular leading edge of the support plate includes a pair of rods angled with respect to the paper webs. As the paper webs flow over the respective rods, opposing twists are imparted to the side-by-side sections of the paper web that causes the web sections to merge towards the centerline of the deflector. The twists in the web sections are removed as the sections loop under a pair of free-floating tension tubes. In this manner, the paper webs are superimposed one over the other for subsequent processing.
