ABSTRACT:
The invention relates to the field of forming fibrous structures. A fibrous structure according to the invention has an upper group of fibrous layers and lower group of fibrous layers subjacent the upper group of fibrous layers. A multitude of Z-fiber bundles cohere the fibrous layers, each fibrous layer within the upper group of fibrous layers having a portion of the multitude of Z-fiber bundles originating in that fibrous layer and passing through a number of fibrous layers disposed beneath that fibrous layer without passing through all of the fibrous layers disposed beneath that fibrous layer. The number of fibrous layers penetrated by the Z-fiber bundles is constant within the first portion.
