Abstract: Methods and apparatus for folding pliable sheet material wherein the sheet material is wound on a mandrel to form a roll which subsequently is stripped off the mandrel and transferred to a pleating station at which successive creases are formed in the roll to produce a pleated packet. During the winding of the sheet material the latter is adhered to the mandrel by the application of negative air pressure to the material via the mandrel. Following the formation of the roll, the application of negative air pressure is discontinued and positive air pressure is applied to the interior of the roll so as to facilitate stripping of the roll from the mandrel. At the pleating station the roll is creased successively to form a plurality of pleats and the direction in which the creasing proceeds is such as to facilitate the escape of air from the roll as it is pleated.

Abstract: An apparatus and method for winding tissue webs into a parent roll is disclosed which results in greater uniformity in the wound tissue roll and improved turn-up efficiency. The apparatus and method includes engaging the tissue web against a reel spool with an air permeable flexible member, such as a transfer belt, which traverses a winding region that includes an unsupported span between two support rolls. The web is transferred from the transfer belt to the parent roll as the parent roll is urged against the tissue web residing on the transfer belt at a point within the winding region. Located along at least a portion of the air permeable transfer belt within the winding region is a pressure reduction means adjacent the belt. The pressure reduction means serves to stabilize the tissue web on the belt improving sheet handling and turn-up efficiency. A sensor measures the deflection of the transfer belt during winding.

Abstract: A method and apparatus for winding film includes haul-in rolls, a spindle, an airhorn, a kick-roll, and a belt or ropes to convey the film. A source of air creates an air curtain downstream of the spindle. The air curtain directs the leading edge of the film into the airhorn and over the spindle. A film guide located upstream of the airhorn guides a leading edge of the film back into its own nip. An air guide located between the film guide and the conveyor leading to the spindle prevents air from going back upstream of the airhorn. The guides are comprised of a non-stick material. Holes near the edge of guide allow air to exit the air horn, without perturbing the film where it tucks into its own nip. A static pinner may pin the leading edge of the film to the spindle. The spindle may have a winding surface tapered by less 0.03 inches per foot. The spindle has an air inlet, and outlet holes. The inlet area is greater than the hole area, by up to a 7:1 ratio.
