"AN IMPROVED MACHINE FOR LINING,
COVERING OR FACING MILLBOARD OR PASTEBOARD WITH PAPER OR OTHER
MATERIAL, AND FOR SIMILAR PURPOSES
39
My Invention relates to an improved machine for lining, covering, or facing mill-
board or pasteboard with paper or other like material.
of
The said machine may also be very advantageously used for pasting two layers
paper together or pasting cloth on paper.
With this improved machine, the work may be performed with great economy as
compared with hand labor, as now ordinarily practised. Moreover the said machine
occupies but very little space, and requires very little attention.
The boards and the paper or other material to be pasted thereon may be used
in the form of sheets or in reels or coils. One sheet of millboard or pasteboard
may be covered or lined on both sides with paper or cloth. Or two sheets or boards
may be covered or lined on one side at the same time.
The cloth or paper to which the paste is to be applied, when used in the form of
continous bands or sheets, is coiled on shafts or spindles into reels or rolls, which
are supported in suitable bearings in close proximity to pasting rolls or cylinders
supported in bearings within a trough or tray containing the paste; these pasting
rolls rotate and gather up the paste to apply it to the said paper or cloth, as the
same passes over the said pasting roll.
Regulating devices are arranged in combination with the said pasting rolls or
cylinders, to vary the thickness of the layer of paste applied to the paper or cloth as
required
I arrange a pair of metal rolls or cylinders to work together at some point
between the two coils or reels of paper or cloth These cylinders are arranged in
combination with a table on which the pasteboard or other material to be covered
or lined is placed to be fed forward to the said cylinders.
The aforesaid continous sheets or bands of paper or cloth are also conducted to
the said cylinders, and the pasteboard or other [substance to be covered or lined

rolls, the pasted sides of the said paper or cloth being in contact with the boards,
and by the pressure of these rolls or cylinders the said paper or cloth is applied to
and securely pasted upon the said boards.
The said machine is provided with cutting mechanism, to which the pasted
continuous sheets pass from the said rolls or cylinders. This cutting mechanism,
which may consist of any suitable knives, shears, or cutters, divides the said
continuous sheets in the required lengths, and these cut sheets or portions of paste-
board or millboard are there exposed to a moderately warm temperature to dry
them.
When the sheets of board are to be coated or lined on one side only, two sheets
of such sheets together with the pasted sheets of cloth or paper are passed together
between the aforesaid rolls or cylinders.
