Abstract
A system of treating web material wherein the web is transported within a differential relative velocity nip defined by a web support surface and a pick-up member having voids therein and having a relative velocity differing from that of the support surface at the nip location. Substantially simultaneously with the web treatment the web is applied to the pick-up member with the web impressed into the voids to lock the web against movement relative to the pick-up member.
