webs of paper and re-reeling them with an equal tension throughout
without puckers or creases, while the trimming of the edges of such webs
has been a separate and distinct operation. Now the object of the
present Invention of improvements in preparing continuous webs of
paper for printing is to pare the edges of the continuous web of paper,
to damp it uniformily, and to re-reel it (with an equal and regulated
tension) at one operation.
By these improvements great economy of time in the preparatory
processes of preparing paper for printing is obtained, while all danger of
puckering or creasing of the web during the re-reeling is avoided. To
attain this end the reel of paper to be prepared for printing is supported
by its journals in the bearing of fixed standards, which may be fitted
with a break if desired. From this reel the web is led over a rollèr
provided with grooves in which revolve circular disc cutting knives,
which are arranged at the requisite distance apart so as to pare the edges
of the web of paper as it passes over the grooved roller. From this
cutting apparatus the paper is led over the upper surface of a metal
roller revolving in a trough of water, and so mounted that the velocity
of its revolution may be increased and diminished in order to regulate
the amount of water served to the under surface of the web as it is
drawn over the metal roller. From this damping apparatus the web is
led over a guide or supporting roller, whose horizontal position is
adjustable so as to regulate the run of the paper. The unwetted surface
of the paper is then carried partly round the periphery of a tension
roller of large diameter, and attached to the core of the reel on which
the paper is to be re-wound. This core or bobbin rests upon the upper
surface of the large or tension roller (so as to be driven therefrom by
friction of contact), it is carried by a balanced lever or frame, by which
its contact pressure on the tension roller may be automatically regulated
as the operation proceeds. Motion is communicated to the paper from
the tension roller, which may be driven in any convenient manner.
