Abstract
Methods for foam forming a multi-layer substrate can include providing a first foam supply including a first supply of fibers and providing a second foam supply. The method can also include providing a supply of particulates. The method can include providing a headbox and a forming surface. The method can include transferring the first foam supply to a first z-directional layer of the headbox and transferring the second foam supply and the supply of particulates to a second z-directional layer of the headbox. The method can include transferring the first supply of fibers, the supply of particulates, and the second supply of fibers through an outlet of the headbox to the forming surface to form a resultant slurry. The resultant slurry can be configured such that the first supply of fibers are directly against the forming surface. The method can include dewatering the resultant slurry such that the first supply of fibers forms a containment layer directly against the forming surface protecting the supply of the particulates from the forming surface.
