ABSTRACT:
An apparatus for the preparation of an elastic absorbent composed of a mixed web. Elements of the apparatus can include two supply hoppers for separately supplying pulverized pulp and staple fibers of a synthetic fiber split yarn at a constant mixing ratio with each hopper having a pair of confronting moving belts, two guide mechanisms located below the hoppers, a pair of nip rollers located below the guide mechanisms, a garnet roll located below the pair of nip rollers, a vacuum device located below the garnet roll, and a mesh belt located between the vacuum device and the garnet roll. Each guide mechanism in the apparatus may include at least two gear guides arranged in series. The apparatus operates by feeding the pulverized pulp and the staple fibers of the split yarn from the hoppers to the nip rolls via the guide mechanisms. The nip rolls compress the material, which is then disintegrated and mixed by the garnet roll. The mixture is pulled onto the mesh belt by the vacuum device.
