Appl. No.:

7/156394

Inventors:

William Willhite - Cincinnati OH

Assignee:

The Procter & Gamble Company - Cincinnati OH

International Classification:

A61L 1500

US Classification:

128156

Abstract:

Method and apparatus for ultrasonically bonding continuously moving webs to one another using a stationary vibrating horn and a relatively slick, non-thermally softenable moving slip layer interposed between the webs to be bonded and the horn to prevent web damage. Interposing the slip layer between the webs to be bonded and the ultrasonic horn improves both the quality and efficiency of web bonding. It reduces friction between the travelling webs and the substantially stationary ultrasonic horn not only due to its relatively slick surface, but also due to the compressive force which the slip layer exerts upon the webs to be bonded. This in turn minimizes jamming and hangups in the very limited clearance existing between the rotating anvil roll and the substantially stationary vibrating ultrasonic horn. In addition, the slip layer maximizes retention of heat either generated in the laminate web by the ultrasonic horn or transferred to the laminate web structure by preheating one or more of the webs. If desired, the slip layer may be comprised of a continuous belt which rotates about the ultrasonic horn.

International Classification:

F26B 300

US Classification:

34335

Abstract:

A method and several exemplary apparatus for capillary dewatering of foam materials. The apparatus may include felt which is applied to an exposed face of the foam material, or a double felt arrangement applied to two opposed surfaces of the foam material. The apparatus may provide a temperature differential between the two exposed surfaces of the foam material. An alternative embodiment utilizes a roll having a capillary dewatering medium. The capillary dewatering medium may be maintained at a vacuum either above or below the breakthrough vacuum of the capillaries. The disclosed apparatus and method is particularly useful for dewatering foams having relatively fine open capillaries.

International Classification:

US Classification:

6043851

Abstract:

Disclosed is a shaped absorbent core suitable for absorbing and retaining aqueous body fluids. The absorbent cores comprise a front panel and a back panel. The front and back panels are made from fluid absorbent material, and each has an inner end, an outer end, and two sides. The inner and outer ends of each front and back panel have a length, with the inner end of each being shorter than the outer length of each. The front and back panels may comprise multiple layers of absorbent material. The absorbent cores also comprise a center section made from fluid absorbent material having first and second ends. The first end of the center section is in fluid communication with the front panel by overlapping the front panel intermediate the front inner and outer ends, and the second end is in fluid communication with the back panel by overlapping the back panel intermediate the back inner and outer ends. A method of preparing a shaped absorbent core comprises the steps of providing at least one continuous rectilinear web of first absorbent material having a longitudinal axis and a pair of lateral edges defining a first width. A continuous rectilinear web of second absorbent material having a longitudinal axis and a pair of lateral edges defining a second width wider than the first width of the first absorbent material is formed with opposing generally arcuate notched areas in the lateral edges at spaced intervals along the web of second absorbent material.

International Classification:

US Classification:

270 65

Abstract:

An interconnected web of disposable diapers containing a pair of continuous, stretched strands of elastic aligned generally parallel to the direction of web travel, is folded along its length from a substantially flat condition to produce a C-shaped, transverse cross-section by means of a conventional board and guide folder. The C-folded web is maintained under tension during the longitudinal folding operation to keep the continuous elastic strands in a stretched condition, and the web is cut transverse to the direction of web travel without releasing the tension in either the individual diapers cut from the web or in the advancing web. Means are provided for transversely folding the individual diapers cut from the web about their midpoints while maintaining the elastic strands associated therewith in a stretched condition and the diaper under positive control. Because the advancing web of interconnected diapers is maintained under positive control at all times, the individual diapers severed from the web are cut in register with respect to one another. This is of critical importance in situations where the web of interconnected disposable diapers is comprised of a plurality of discrete, interconnected diaper segments rather than a continuous web of disposable diaper material having a uniform cross-section throughout its length.

International Classification:

US Classification:

Abstract:

An apparatus for unwinding a roll of web material which is prone to blocking: for example, an elastomeric film which, while rolled, is prone to having the convolutions of the roll stick together. The apparatus induces a sufficiently high rate of strain in a short span adjacent the roll to effect continuously peeling the outermost convolution from the roll. Additionally, the apparatus is of such a geometry that, in the event blocking precipitates circumferential shifting of the point of web separation from the roll, the stripping angle is increased. This, in turn, increases the effectiveness of the rate of strain induced peeling force on the web whereby more positive peeling occurs.
