of such trimmings it is desirable that the welt with
oneof its margins folded o_ver in conformity

with
an intermediate step in the‘manufacture of „
ness, to enhance the ornamental effect, and to
,
,
render the trimming more durable and prevent the core;
it being readily disengaged from applied position. '1 Fig. 3 is a cross sectional view _of a completed

rating in the folded fabric one or more cores or
fillers, and it is to this element of the'trimming
molding that my invention relates. Heretofore
various different mediums have been employed in
2 Ul fabricating trimming cores, including strips of
leather, cords and roving of cotton, jute, and
paper, and molded or extruded rubber.v The
structure provided by my present invention is
superior to those heretofore known in that it is
30 less expensive, more easily made, more readily
formed toany desired shape, and because it pos
sesses a superior compactness, firmness, resilience,
and nexibility.

'
Much difñculty has heretofore been experi.
3 Ul enced with deterioration of welts and’analogous
trimming moldings, particularly the cores and
ñllersxthereof, on exposure to weather.
Such ex
posure commonly results in rotting of the mate
rial and eventual breaking down of the> whole
4 O structure. My present invention provides a core
or filler which is thoroughly and permanently
Waterproof and which consequently provides «a
45
durable andunchangeable foundation for perma
nently sustaining the covering and other trim
ming molding elements.
Yl

.
An important quality of any trimming molding
element is its capacity to be disposed about curves
of short >radius without objectionable puckering
and buckling and Without imparting kinks and
similar deformations to the molding as a whole.
My present core possesses these smooth» bending
properties to a high degree, and welts which in
clude it are capable of being disposed about short
curves in the flat plane of the welt without ap
55
preciable puckering, buckling or kinking.
A further advantage of the present invention
is the capacity of cores or fillers made according
to it to be built up to any thickness desired, be
60
tween any limits usual in trimming molding prac

' Broadly, the invention comprises a core of the
class described which is formed of a strip of
coarse fabric, such as 'jute -burlap impregnated`
with an adhesive composition, folded over o_n it
_self to provide two or more plies, enough to give
30v
the resulting body the thickness desired.4 Thus.
lfor example, the core may comprise such a strip,
`having both of its marginal portions folded. over
the central zone of the strip and moderately com
pacted together. ’ so that 4the _resulting structure
isof three-ply thickness throughout mostv of its
width, as shown in Figs. 3 and’ 4. i After >the ad
hesive has begun to set the completed core com
prises a substantially unitary body. ¿the several
plies and the plurality of threadsjbeing' ñrmly .f
bonded together. User of a _preferred type of
adhesive composition results in thesurface of
vthe completed core remaining "comparatively
tacky or being frictioned, fora considerable 45
period of time, whereby the conventional trim
'ming moldingr covering material is adapted firm
ly to bond with the core so that relative sliding
movement of thev core and covering is prevented.
' I form my novel core or filler by providing jute 50
burlap or .analogous coarse fabric in a strip of
indefinite length and approximately, in the case
of the k,example chosen for illustration in Figs.
2,13, and 4,»three times the widthdesired for the
completedïfoore.` The- strip, shown at I in
l, .55
is coated and preferablythoroughly impregnated
with an adhesive filler composition as indicated
at 2 in Fig. 1.
'
While the adhesive composition is still tacky
and comparatively nuid one side margin 3 of the 60
