page_text: We, FRIEDRICH HUGO PEUCKERT, of 17, Stelzendorfer Strasse, Siegmar, Saxony,
Germany, Merchant, and PAUL DRECHSLER, of 25, Rosmarin Strasse, Siegmar,
Saxony, Germany, Machine Maker, do hereby declare the nature of this-invention and
in what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement:—
Our said invention relates to a machine for cutting strips of any desired width
from wide rolls of paper linen and the like but more particularly of fine tulle-like and
unstiffened soft materials.
In order that our said invention may be more clearly understood we will describe it
with reference to the accompanying drawing in which
Figure shows a sectional elevation and
1
Figure 2 a plan of a machine constructed in accordance with our said invention.
Figures 3 and 4 show respectively sectional elevation and plan of the principal
cutting arrangement.
Figure 5 shows a plan of an auxiliary cutting arrangement.
In order that soft materials may be cut by a single rotary knife b the material
must be pressed firmly on the grooved bar or table c (Figs. 3 and 4). According to
our said invention we obtain this pressure by using on both sides of the knife b
rollers 2 which are free to rotate and which are held in position by adjustable
collars qq. The rollers 2 have such a diameter that they touch the material as
it passes between the rollers and the table. In order to produce the necessary
pressure against the material the bar c which is hinged at c² to the carrier ³ (Fig. 3)
The bar c forms a cutting
is pressed upwards against the rollers 12 by a spring s.
table and has a groove ct into which the knife enters.
When the material is of such a nature that a great cutting speed is possible the
pressing rollers 12 may be fixed to the knife-shaft so as to rotate therewith.
With very soft materials the rotating knife b may be set so near to one edge of the
groove c as to forin a shear therewith.
In a machine (as shown in Fig. 2) the grooved tables c are arranged at suitable
distances from one another so as to cut strips of the desired widths. The strips are
drawn off by and wound on two rows of spools ƒ and g (Figs. 1 and 2). In order to
keep the cutting speed constant while the spools gradually increase in diameter two
helt cones and i with a belt traversing device of the usual construction are used to
transfer the motion of the main driving shaft to the spools.
The machine represented in Fig. 2 transfers the whole width of the roll of material k
in strips but in order to make the machine suitable for smaller makers the arrange-
ment shown in Figs. 1 and 5 is provided. In the arrangement here shown a rotating
circular knife m cuts the roll of material into two parts one only of which is
unrolled at a time to be cut into strips. By this means the cutting machine may be
made much narrower and the power necessary to operate it much smaller.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is
1. A strip cutting machine substantially as set forth and described.
2. A strip cutting machine having laterally adjustable spring pressed grooved bars
or tables in combination with circular cutting knives having pressing rollers at the
sides thereof substantially as and for the purpose set forth and shown.
3. A strip cutting machine in-combination with a circular knife m substantially as
and for the purpose set forth and described with reference to Figures 1 and 5.
