element 20 includes a plurality of supporting
portions 2| and a plurality of pleating portions
22'. The supporting portions are wider than the
pleating portions, so that the former have the
projections 23 and 24 while the latterhave the
indentations 25 and 26. The outer longitudinal
edges, forming the indentations 25 and 26 need

25-, or conversely, the tape element may be formed
by taking a piece of tape of a width equal to the
distance between the outer edges of the indenta
tions 25 and 26 and adding on the material to
form the projections. One advantageous meth
odof forming the tape element 20 is to cut a
web of fabric 29 with cuts 3| and 32, ‘so that
the projections on one tape element dove-tail
into the corresponding indentations of the tape
elements on either side thereof.
This is shown
in Figure 2 of the accompanying drawings, in
In the second embodiment, the supporting por
tions 2 I ' are separated by groups of three pleating
portions 22', and between the pleating portions
32’ in any group there are two smaller or auxiliary
supporting portions I2 I. This arrangement of the
parts produces a triple pleated effect. By vary
ing the size and arrangement of the pleating por
tions 22’, the supporting portions 2|’, and the
supporting portions I2I, substantially all of the
various conventional drapery and curtain pleating
which the cuts for producing the indentations in 50 arrangements may be obtained. .
the outermost strips are indicated by the refer

By properly correlating the distance between
~ the outer edges of the projections 23 and ‘24 with
the distance between the rows of stitches 25 and
'26, the tape element 2!] may be installed upon
the panel‘ II as‘a single operation on a two nee
dle sewing machine.
I ' i!
In an valternate form of construction, the inner
'or forward surfaces of the projections 23 and
24 may be provided with adhesive‘ material, such
as a thermoplastic adhesive, or thermosetting
adhesive, by means of which the said projections
and hence the supporting portions may be con
nected to'the curtain or drapery panel II. The
pleating portions are free of connection, save
through the supporting portions, with the cur
tain or drapery panel II. While the tape ele
‘ ment 20 has been shown and" described as being
fa separate‘strip of fabric, the lower edge (the
free edge’seen in Figure '6) maybe extended
downwardly a ‘distance equal to the width of the
tape element and may be slit as shown ins-Figure
9. The lower edge just referred tojis the lower
'- edge of the top hem, I
I20 and 220 may be provided, the former being
in the middle portion of the. panel II’, and the
latter adjacent the lower edge I3’. When the cur
- tain I0’ is mounted on appair of spaced and par
allel rods 30' and 230, the pleating effect is ob
tained at both ends of the curtain. This construc
' tion is desirable ford‘o'ors, and the like where it
' is customary‘or desirable to anchor the curtain
at both its upperand lower edges. ‘
The tape element I20 and the portions of the
panel I I immediately adjacent may-be constricted
by a ribbon or strip I30 to produce an hour-glass
effect when the upper and lower edges of the
curtain panelare supported on rods, or a conven
tional tie~back effect when only the upper edge
of the curtain panel is supported. The tie-back
' effect thus provided’ however, will have the pleats
hereindescribed, in predetermined positions as
contrasted with the haphazard ‘gathering or
shirring normally'obtained.
Turning now to the third embodiment of the
invention illustrated in Figures 13 and 14,, again
for the purpose of _ avoiding needlessrepetition,
parts corresponding to the ?rst'embodiment are
given the same reference characters with the
addition of a double prime su?ix.
In accordance with the construction of the
third embodiment, the tape element 20" may be
of uniform width so that standard tapes or fabric
strips may be used as the base of the tape ele
ment. At spaced intervals along one edge of the
tape element 20" areas of adhesive material 3|‘!
are provided, and oppositely, at similarly spaced
intervals along the other edge of the tape ele 10

provided. The lengths of the areas 3|‘! and 3l8
