Patent

CA 2027880

An on-line coater apparatus is disclosed for coating a web of paper. The apparatus includes a dryer section having a plurality of single-tier dryer groups, each successive group drying an alternate side of the web, the web being restrained against cross-machine directional shrinkage during passage through the plurality of dryer groups. A further single-tier dryer group is disposed downstream relative to the plurality of groups such that the web extends in an open draw between the plurality of groups and the further group. A tail cutter is disposed adjacent to the open draw for cutting a tail from the web for subsequent threading through the further group. A calender is disposed downstream relative to the further group for calendering the dried web. A coater is disposed downstream relative to the calender for coating one side of the web, and a single-tier coating dryer group is disposed downstream relative to the coater for drying the coated one side of the web. A winder is disposed downstream relative to the coating dryer group for winding the coated web.
