Wide wale tissue sheets and method of making same

In the manufacture of tissue roll products, such as bath tissue and paper towels, uncreped throughdried products have gained wide acceptance with consumers. These products are characterized in part by their high bulk, three-dimensional texture and resilience. In the case of paper towels, exceptional bulk is provided by contoured throughdrying fabrics that impart high and wide wales or ridges that run in the machine direction of the product. In the case of bath tissues, the same technology is utilized, but the throughdrying fabrics employed impart a smaller scale topography to the product. While it would be desirable to use the same throughdrying fabric for both towels and bath tissue from the standpoint of manufacturing efficiency, using the more highly contoured towel throughdrying fabric for making bath tissue causes two significant problems. Highly textured tissue sheets, particularly suitable for use as bath tissue, are produced by throughdrying and have a low number and/or low amount of pinholes. The low number or amount of pinholes is provided by using a throughdrying fabric having parallel wide ridges with a height suited to the particular tissue sheet being produced.
