PROCESS AND APPARATUS FOR EMBOSSING TISSUE PLIES

摘要

A process to mate a plurality of tissue webs includes in one embodiment providing first and second steel rolls and a second steel roll. The first steel roll has first protrusions, and the second steel roll has recesses. The embodiment includes forming a rotary nip between the first steel roll and the second steel roll, and advancing the plurality of tissue webs through the nip. The embodiment includes embossing first and second embossments into the plurality of tissue webs to connect the tissue webs to one another. The first protrusions press a first series of portions of the plurality of tissue webs into the recesses. The second embossments are created by one of pin-to-flat and pin-to-pin embossing. An apparatus suitable for carrying out the process is also disclosed.

主权项

1. An apparatus to mate a plurality of tissue webs via embossing, the apparatus comprising:
an embossing roll having an embossing roll primary surface, the embossing roll comprising first protrusions and second protrusions, each first protrusion protruding a first height from the primary surface and each second protrusion protruding a second height from the primary surface, the first height being greater than the second height; and a counter roll having a counter roll primary surface, the counter roll comprising recesses, wherein the embossing roll is rotatable about a first axis of rotation and wherein the counter roll is rotatable about a second axis of rotation, wherein the embossing roll and the counter roll together form a rotary nip and are positioned such that the first protrusions individually extend into the recesses proximate the nip as the embossing roll and counter roll simultaneously rotate, and such that the second protrusions do not extend into the recesses as the embossing roll and counter roll simultaneously rotate.
