5. The process of claim 1, further comprising the step of: combining a continuous backsheet web with the combined continuous topsheet web, liquid acquisition layer, and absorbent core exit the embossing nip.
6. The process of claim 1, further comprising the step of heating the patterned embossing roll.
7. A process for assembling disposable absorbent articles, each absorbent article comprising a chassis having a first waist region longitudinally opposed to a second waist region, and having a longitudinal axis and a lateral axis, the chassis comprising: a topsheet, a backsheet, and a liquid acquisition layer and a substantially cellulose free absorbent core disposed between the topsheet and the backsheet, the process comprising the steps of:
advancing a continuous topsheet web having a first surface and an opposing second surface in a machine direction;
combining a liquid acquisition layer with the continuous topsheet web, wherein the liquid acquisition layer includes a first surface and an opposing second surface, and wherein the first surface of the liquid acquisition layer is positioned in a facing relationship with the second surface of the continuous topsheet web, wherein the liquid acquisition layer comprises an upper acquisition layer and a lower acquisition layer;
combining an absorbent core with the liquid acquisition layer, wherein the absorbent core includes a first surface and an opposing second surface, and wherein the first surface of the absorbent core is positioned in a facing relationship with the second surface of the liquid acquisition layer;
providing an embossing nip between a rotating embossing roll and a rotating anvil roll, the embossing roll comprising an embossing element; and
creating indented regions in the continuous topsheet web and the upper acquisition layer without bonding the continuous topsheet web and the upper acquisition layer together without creating indented regions in the lower acquisition layer and the absorbent core by advancing the combined continuous topsheet web, liquid acquisition layer, and absorbent core through the embossing nip, wherein the embossing element contacts the first surface of the continuous topsheet web, and wherein the rotating anvil roll contacts the second surface of the absorbent core.
8. The process of claim 7, wherein the step of combining a liquid acquisition layer with the continuous topsheet web further comprises the operation of applying adhesive to the second surface of the continuous topsheet web.
9. The process of claim 7, wherein the step of combining an absorbent core with the liquid acquisition layer further comprises the operation of applying adhesive to the second surface of the liquid acquisition layer.
10. The process of claim 7, wherein the upper acquisition layer defines the first surface of the liquid acquisition layer and the lower acquisition layer defines the second surface of the liquid acquisition layer.
11. The process of claim 7, further comprising the step of: combining a continuous backsheet web with the after the combined continuous topsheet web, liquid acquisition layer, and absorbent core exit the embossing nip.
12. The process of claim 7, further comprising the step of heating the embossing roll.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. An exhaust-gas recirculation (EGR) valve comprising a rotary drive, said rotary drive having a cam member with a cam profile, said rotary drive permitting operation of a valve member that can be rotated around a rotational shaft, a rotation of said cam member resulting in a rotation of said rotational shaft, wherein during the course of a closing movement, said EGR valve can, toward the end of the closing movement, move toward a valve seat in a direction that is generally parallel to a direction of flow through said valve seat, wherein said valve member comprises at least one aperture that can be opened during the course of an opening movement before said valve member is separated from said valve seat.
2. The EGR valve according to claim 1, further comprising a closing member for said aperture within said valve member, said closing member being separate from said tab.
3. An exhaust-gas recirculation (EGR) valve, comprising:
a rotary drive;
a cam member having a cam profile, said cam member cooperating with said rotary drive;
a shaft rotatably cooperating with said cam member whereby a rotation of said cam member results in a rotation of said shaft;
a valve member cooperating with said shaft whereby said rotary drive rotates said valve member about said rotational shaft; and
a valve seat cooperating with said valve member;
wherein during the course of a closing movement and toward the end of the closing movement, said valve member moves toward said valve seat in a direction that is generally parallel to a direction of flow through said valve seat,
wherein said valve member comprises at least one aperture that can be opened during the course of an opening movement before said valve member is separated from said valve seat.
4. The EGR valve according to claim 3, further comprising a closing member for said aperture within said valve member, said closing member being separate from said tab.
