Abstract

Method and apparatus to heat fix a heat fusible xero~ graphic powder image to a final support material in which the powder image is first transferred to a final support material and the image-bearing support material then brought into contact with a bath of hot liquid metal for a period of time sufficient to fix the image to the support material. The temperature of the bath is main- tamed at a temperature high enough to fuse the image but below that at which the support material is damaged. The liquid metal bath has floating on it a layer of molten non-metal to prevent oxidation of the metal and to precoat the support material on its entry into the

Method and apparatus to heat fix a heat fusible xero~
graphic powder image to a final support material in

which the powder image is first transferred to a final support material and the image-bearing support material then brought into contact with a bath of hot liquid metal
for a period of time sufficient to fix the image to the support material. The temperature of the bath is main- tamed at a temperature high enough to fuse the image
but below that at which the support material is damaged.
The liquid metal bath has floating on it a layer of
molten non-metal to prevent oxidation of the metal and
to precoat the support material on its entry into the

bath to prevent particles of the liquid metal from
embedding in the support material. The relative high
density of the molten metal acts as a wringer to keep
the plasticized coating very thin when drawn out of

the bath.
