Abstract: Disclosed is an apparatus for longitudinally pleating a moving lamina. The apparatus features a curved axis roll having a stationary axis circumscribed by a rotating sleeve with a plurality of circumferentially oriented grooves in the rotating sleeve. The pleats are produced by the intermeshing of the lamina with the grooves of the rotating sleeve. Preferably a complementary curved axis roll having lands which interdigitate with the grooves of the first roll is used in conjunction with the first curved axis roll.The apparatus preferably further comprises a third curved axis roll disposed upstream of the first curved axis roll to substantially equalize the paths of travel of any points on the moving lamina by compensating for differences in the paths of travel between the edges and centerline of the lamina.

Abstract: An apparatus for forming packaging material into a tubular form includes angularly disposed forming rollers for causing the longitudinal edges of the packaging material to overlap one another so that they can be sealed together. To prevent the packaging material tube from being trapped between adjacent rollers, each of the forming rollers can be provided with one straight roller edge and one chamfered roller edge. The rollers are positioned such that the chamfered roller edge of one forming roller cooperates with the straight roller edge of the adjacent roller, thereby defining a nip directed generally tangentially to an adjacent portion of the packaging material tube. Alternatively, to achieve the same objective, two different types of forming rollers can be employed, one type in which both roller edges are straight and another type in which both roller edges are chamfered. In this latter case, the two types of rollers are alternated with one another.
