    Abstract: An expandable absorbent structure comprises an expansion loop core configured to expand in response to absorption of a liquid and an expansion loop material structure surrounding the expansion loop core and having a trough therein, wherein the trough is formed from a first portion of the expansion loop material structure folded over a second portion of the expansion loop material structure at a first elbow of the expansion loop material structure. In response to an increase in size of the expansion loop core, the expansion loop core presses against the expansion loop material structure to cause a length of the trough to decrease.

    Abstract: An apparatus for splicing comprises a first web support surface configured to support a traveling web thereon and a second web support surface configured to support a replacement web thereon. The first traveling web travels in a machine direction. The splicing assembly also comprises a first web sensor and a web joiner. A controller is configured to determine, via the first web sensor, a position of a trailing end of the traveling web and to, in response to determining the position of the trailing end, cause a leading end of the replacement web to be positioned adjacently to the trailing end. The computer is also configured to control the web joiner to create a joint coupling the trailing end to the leading end.
