together define a waist opening, a crotch section 16 situated
between a pair of marginal leg openings 18 (see col. 4, l. 25
through col. 5, l. 1) and elastomeric nonwoven laminar fabric
strips 102 and 104 provided along the margins of the leg and
waist openings (see col. 9, ll. 35-39). With reference to
Figures 16-18, Proxmire also teaches a method for making the
laminar fabric comprising the steps of sandwiching a
elastomeric film or nonwoven carrier sheet 110 between at
least a pair of nonwoven facing sheets 112, 114 and bonding
the facing sheets 112, 114 together by ultras-onically or
thermally-generated bonds through the carrier sheet
110 at spaced apart sites 116, thereby forming apertures 120
through the carrier sheet which laminate the carrier and
facing sheets 112, 114 together at the spaced apart sites 116.
The carrier sheet 110 and facing sheets 112, 114 can be bonded
together while the carrier sheet is stretched as shown by FIG.
17 or the carrier sheet can be sandwiched between a pair of
creped or microcreped nonwoven facing sheets while the carrier
sheet is in an unstretched or a partially stretched condition,
