This invention relates to an improvement in
paddings for laundry pressers, ironers and other
similar devices, and has for its main object the
provision offa serviceable, eiiicient andV highly
‘ satisfactory padding of this character.
The required desirable characteristics of a
padding -of the kind referred to are, among
relates is shown at 5 in Figs. 1 to 3 inclusive, and
at 6 in Fig. 4. In the use shown in Figs. 1 to 3, `
it forms a central-layer, being lo‘cated between '
an outer textile fabric covering or ply 8 and an in
ner fabric layer 1, on the roll 9. The padding 5 5‘ ‘
is composed of an elastic, yieldable -cellular ma-y

The improved padding to which the invention
Where increased absorbency is required, abrad- 40 ~
ing' in the manner described is recommended.
The mixture produced, namely of sponge rub
ber and a _fibrous material, produces a padding I
possessing'a high degree of yieldability or resili- l
ency and at the same time _one whose body does 45
' not‘distortionally shift or >flow during the press
ing operation, and particularly when projections
such-as buttons' on a garment or the like pass
between the pressing surfaces. This results in
a very effective pressing or ironing action, par- 50
ticularly in the area of the article being ironedsurrounding the button or projection thereon.

The use of4 wool ñbres as part of the mixture
in the padding produces a highly satisfactory
degree of absorbency, the moisture thereby ab- V55 '
