0 24 grams per cubic centimeter according to the potentially preferred practice of the present invention following formation of the enhanced density batting material 56 a plurality of such rolls of enhanced density batting material 56 are thereafter conveyed to a laminate formation station 60 as illustrated in fig5 at the laminate formation station 60 the enhanced density batting material 56 is preferably conveyed in overlying and underlying relation to intermediate layers of adhesive material 62 thereby forming a sandwich structure 66 in which the adhesive material 62 is disposed between the layers of enhanced density batting material 56 while the formation of a sandwich structure 66 incorporating only three layers of enhanced density batting material 56 is illustrated thereby corresponding substantially to the illustrated nonwoven structure 10 in fig1 it is to be understood that a larger number of layers of enhanced density batting material 56 may likewise be formed into a sandwich structure 66 with intermediate layers of adhesive material 62 between such layers if desired it is likewise contemplated that materials other than batting material such as woven knit stitched or thermal bonded material may be substituted for one or more of the rolls of enhanced density batting material 56 during formation of the sandwich structure 66 so as to derive the properties of such materials according to the potentially preferred practice the resultant layered sandwich structure 66 is thereafter conveyed through an entangling needle loom 64 which serves to mechanically intermingle a portion of the fibers from one or more layers of enhanced density batting material 56 with the adhesive material 62 and with the adjacent layer of batting or other material as may be incorporated within the sandwich structure 66 thereby mechanically binding the layers of.
