Abstract: A fiber containing aggregate, for example, a filler material for covers or pillows, for cushioning or as a filter is described, together with a process for its preparation.In order to provide an aggregate wherein the fibers are located and distributed three-dimensionally in the manner desired, and, if so desired, remain in such a distribution and which has improved properties in particular as a filler material, it is proposed to place an assembly of spherically entangled fibers and/or filaments into a form desired and to bond the fiber balls to each other.The fiber balls are joined together in particular by means of binder fibers, which may consist of, for example, melting fibers, soluble fibers or adhesive fibers. Melting fibers have a melt-on temperature which is lower than the melt-on temperature of other fibers of the aggregate and are activated by the application of heat.

Abstract: An improved method of forming an article includes providing continuous woven, flat, helical tape of filaments and a continuous flat, helical tape of foil. The two helical tapes are interleaved to form a helical assembly having turns of filaments alternating with turns of foil. Deformation forces are applied against the turns of the helical assembly in a direction parallel to the central axis of the helix to bond the turns of the tapes of foil and filament together while maintaining the filaments free of axially extending forces. During the bonding of the turns of the helical foil and filament tapes, the tapes may be bonded to a housing or other component of an article to be reinforced. Radial reinforcing can be provided by including in the helical assembly a layer having filaments with central axes which are radial relative to the central axes of the filaments of the helical tape.
