A plate configured to contact a web includes a first region having a first characteristic and a second region having a second characteristic different than the first characteristic. The plate has a substantially arcuate wall with an inner surface and an outer surface. A plurality of vacuum holes extends between the inner and outer surfaces and are configured to be in fluid communication with a vacuum source. A vacuum region is adapted to contact the first region of the web and a reduced-vacuum region is adapted to receive the second region of the web. The plurality of vacuum holes are configured such that, when attached to the vacuum source, a vacuum pressure at the vacuum region is greater than a pressure at the reduced-vacuum region so that the first region of the web is held against the plate with a greater force than the second region.
