<p>A paper tail nip threader for guiding a moving paper tail over and around a contoured surface. The apparatus is particularly useful for automatically threading a paper tail through a calender roll stack.</p><p>A guide surface is shaped to conform to a portion of the surface over which the paper is to be passed. An air stream is directed across the guide surface in the desired direction of movement of the paper. The air stream is thus forced to flow in a contoured path which corresponds to the surface over which the paper is to be passed. The moving air stream "catches" the paper tail and carries it between the guide surface and the surface over which the paper is to be passed.</p> |
