Abstract:
An apparatus for dry forming an absorbent core composite comprising:a rotatable drum having a substantially cylindrical surface; a vacuum surface comprising one or more holes disposed substantially circumferentially around at least a portion of the substantially cylindrical surface; a vacuum chamber, disposed within the rotatable drum, having one or more vacuum passages forming a vacuum zone subadjacent at least a portion of the vacuum surface; a first casing sheet supply mechanism for supplying a first casing sheet to overlie the vacuum surface at a first location; a fibrous material supply mechanism for supplying fibrous material to overlie the first casing supply at a second location; a particulate matter supply mechanism for depositing particulate matter onto the fibrous material at a third location; and a second casing sheet supply mechanism for supplying a second casing sheet to overlie the first casing sheet, the fibrous material and the particulate matter at a fourth location, thereby forming an absorbent core composite.
