Abstract

Apparatus is provided for automatically effecting a widthwise folding of a long, flexible web advanced therethrough. The web is trained about a first roller at a point where the folding begins and about a second roller at a point where the folding ends. A displacement edge or bar is mounted in a fixed location equidistant from the first and second rollers, and a portion of the web is trained about the displacement edge or bar during the folding. Webs of different widths are accommodated by adjusting the positions of the first and second rollers without changing the shapes of three similar triangles. The first triangle is defined by a first point where a first edge of the web intersects the first roller, a second point where the same edge of the web intersects the second roller, and a third point where the opposite edge of the web intersects the first roller. The second triangle is defined by the first point, a fourth point where the first edge of the web intersects the displacement bar or edge, and a fifth point midway between the first and second points. The third triangle is defined by the second, fourth and fifth points. The distance between the fourth and fifth points is half the distance between the first and second points.
