US Classification:

425 821, 425 831, 425403, 4254051, 264119, 264518, 156443, 156578

Abstract:

An apparatus and method for forming tow-based absorbent structures having a single casing sheet are disclosed. The apparatus has a tow supply mechanism for providing tow material, a particulate matter supply mechanism for providing particulate matter, and a casing sheet supply mechanism for providing casing sheet material. The apparatus also has a vacuum draw roll having a foraminous center surface that has a width defined by a first edge and a second edge and is rotatable about a first axis. The vacuum draw roll is positioned to receive the tow material, the particulate matter and the casing sheet material to form a open core composite supply. The apparatus also has one or more angled surfaces positioned to create one or more obtuse angles in the open core composite supply, and one or more folders to further fold the one or more obtuse angles in the open core composite supply to form a folded core composite supply.

US Classification:

427180, 118308

Abstract:

A particulate delivery apparatus for distributing particulate material onto a target area of a web moving in a first direction can generally have a hopper for receiving a supply of particulate material and a one or more tubular members having an inlet end communicating with the hopper and an outlet end for discharging the particulate material from the hopper onto the target area. The tubular member(s) can extend downwardly from the bottom of the hopper at an angle toward the web, such that the particulate material is discharged onto the web, and in the same direction the web is moving. A plurality of separate flow paths can be provided in the tubular member(s) such that the particulate material is discharged as a plurality of separate streams. The width of the outlet end(s) can approximate the width of, and be oriented along the same axis as, the width of the target area.
