ALFRED JULIUS BOULT, of the Firm of W. P. Thompson and Boult, Agents for
Foreign Patent Solicitors, of 323, High Holborn, London, in the County of
Middlesex, Engineer and Patent Agent. "IMPROVEMENTS IN GLOSSING MACHINES."
A communication from abroad by the Firm of C. G. Haubold, J., of Chemnitz,
Saxony, Germany.
For producing gloss or shininess upon cloth and other woolen goods, what are
termed "roller-presses" are used. In these the goods to be rendered glossy are
drawn through a rotating roller and a fixed heated trough, so that the same rubs
against the trough.
For the same purpose what are termed friction callendering machines are also
used. In these a smoothing or glossing roller rotates at a higher speed than the
other rollers, working together therewith, which guide the material upon which
gloss is produced by the greater speed with which the glossing roller rotates in
comparison with the speed of the material. Lastly, there are the so called felt
callendering machines and finishing cylinders in which the felt between the cloth
and the drum rotates at the same rate as the drum.
The Invention as communicated to me by my foreign correspondents can be -
arranged either vertically, diagonally, or horizontally, the latter disposition perhaps
having the advantage in some points, but for convenience I will describe the vertical
machine.
This consists essentially of two frames or standards carrying three rollers
arranged one above another; the centre one of these is hollow, and can be heated
by steam or hot air in any convenient manner. An endless band of felt, sheet
metal, or cardboard it passed round the bottom roller between it and the middle
one, embracing rather more than half of it between the middle and top ones,
partly round the top one and over and outside supplementary roller. The central
or heated roller is driven independently of the lowest one, and preferably at a
different speed, and the lowest roller is driven by friction gearing so arranged as
to be capable of varying the speed at pleasure. This roller is made longer than the

page_text: central one, so as to give increased bearing surface for the endless band, so as to
carry it over the central one without slipping upon the larger roller. The material
to be glossed, such as cloth, textile fabric, or paper is carried on a roller near the
bottom of the machine, laid against the endless band, and so pressed firmly against
the hot roller, carried past it, and again rolled up near the top of the machine.
Suitable pressure is placed upon the rollers by screws, weights, or the like,
adjustable according to the requirements of the article operated upon..
By means of this machine one side of a material with patterns in raised threads,
such as ribbed and damask goods and the like, can be well glossed; whilst the
raised threads on the other side are pressed into the felt of the endless band.
The machine may operate independently or in conjunction with other finishing
machinery, especially with what are termed felt callendering machines, cylinder
drying machines, and the like.
