CUTTING MECHANISM FOR. FINISHING
MACHINES
Max W. Winkler, Northampton,- Pa., assignor to
Queen City Textile Corporation, Allentown, Pa.,
a corporation‘ of Pennsylvania
Application February 18,1936, ‘Serial No. 64,545
49 Claims. \(Ol; 26-7)
This invention relates to cutting mechanisms
for trimming the edges and slitting a traveling
web of warp knit fabric as the fabric. is treated
on the ?nishing machine.
5
It is the aim of the present invention to ob
viate the necessity of a separate machine for
slitting the travelingfabric and cutting the edges
thereof by combining the slitting and cutting
mechanism with the conventional ?nishing ma
' 1o chine on which the travelingweb of fabric is
dried and stretched in the same operation.
One of the essential features of j the present
invention is the arrangement of the cutting mech
anism to trim the edges of the knit'fabric on :-the
15 ?nishing .machine' thereby
leaving an 7 even
smooth edge that facilitates rolling into neat
bolts which edges are customarily curled and full
of pin holes from the tentering pins, and these
curled edges impede’ the rolling of the fabric into
20
bolts-
'
,
,
;.:::3
In the conventional process the‘ intermediate
portions of the web of knit fabric will__ dry long
before theedges. It is therefore another feature
of the present invention to reduce the ‘time ordi
25 narily consumed by-the ?nishing operation and
to increase the speed of the machine by devis
ing a construction that severs the damp.- edges
of the fabric as it comes from the drying cham
her on the ?nishing machine thereby saving the
30 difference in the amount of time consumedin
drying the edges and the amount of time required
to dry intermediate portions of the web,
‘
Further objects of the present invention are
to provide cutting mechanisms of the, character
35 referred to that are strong, compact and durable,
very easily manipulated, thoroughly reliable for
their intended purposes, adaptable ;to the con
ventional ?nishing machines, and comparatively
inexpensive to manufacture and install.

With the foregoing and other objects inv view

combination and arrangement of parts as will

illustrated in the accompanying drawings,‘ where
45 in the embodiments of the invention are disclosed,

comes to the ?nishing machine in the wet condi

width- The side edges of the web are forced

loading end of the machine with intermediate
portions stretched between the chains. The ten
tering chains I‘! travel under power supplied by
the machine, carrying the stretched web Hi from
the loading end to the delivery end of the finish
i-ng machine A where the web passes around a
wardly.
The‘opposite margins of the web l6
pass under this shoe plate and an intermediate
portion of the‘ plate has an elongated slot 29 20
through which ‘a segment of the rotary cutter
disc extends when the disc is in cutting position
as will later appear. The inside or ?xed section
of a pair of companion sections that form the
"cutter guard hood 30a has a flange 3| riveted
‘or otherwise secured at '32 to the top face of the
shoe plate ?i-adiacent the slot 29. This ?xed

A' pivot pin 40 extends across the pair of brackets
and the ends of the pin are secured in the upper

the web passes through the drying chamber of
conventional construction (not shown) and comes
of the machine A rearwardly of the drying cham- .
her is shown, it will be seen that there is one
ledgeftrimming member B on one side and an
other edge trimming member C on the other side
both of which are in alignment with each other.
These edge trimming members trim the curled
‘edges 22‘ ‘from the web of knit fabric while the
web is continuously traveling on the tentering
chains l1. Under certain conditions it may be
desired to cut the web in half in a longitudinal
direction. In ‘this event the single slitting mem
ber D is thrown into operation. In event more
than two lengths of fabric are vdesired, then the
multiple slitting member E, shown in Figures 11,
12 and 13 is attached to the machine or moved
"into cooperation therewith. It is pointed out that
whether the single or multiple slitting members
D and E are used, the cutting discs of either are
in transverse alignment with the cutting discs
of the edge ‘trimming members B and C.
Furthermore, the edge trimming members B
and C‘ are arranged to bear on top of the web 16

a pulley 48 mounted thereon which is driven by
an "endless-belt 49 from the motor pulley 31. On '60
the inner end of the drive shaft 41 is the cutter
disc 41a.
The movable companion section of the cutter

The arm 80 extends through the recess 54 in
the hood. On the projecting end of the guide
arm slides a sectional sleeve-like carriage 62
which has a pair of integral arms 63, 84 in which
30 are journaled a pair of abrading wheels 65, 66
made of carborundum or other like abrading ma
terial.
The abrading peripheries of these
wheels, 65, 66 are arranged on the opposite sides
of the cutting edge of the cutter discs 41a as
35 shown in Figure 6 of the drawings and when
they are brought into engagement with the cut

The carriage 62 is maintained on the upper

the ?nishing machine A.
This latch arm 98 is
positioned on the machine at approximately the
middle of the 1ever'96. On the free upper end
of the latch arm is a lateral prong IOIi in the
notch I02 of which seats the corner of the lever
0.6 when the cutter disc 88 is- in cutting position.
as When it is desired to move cutter disc 88 from
cutting engagement with the web, as shown in
Figures 9 and 10, the lever '96 is pressed down
wardly and then ?exed side-wise free of the notch
I02 whereupon the .arm 89 swinging on pivot 00
moves the cutter 88 downwardly and out of cut
ting engagement with the web II6. It is pointed
out that the cutter disc .88 is in transverse align
ment with the cutter discs 410. on the edge trim—
ming members B and C.

It is sometimes necessary to slit the web 16
into narrow pieces that require the use of more
than one cutting disc. ‘This multiple slitting mem
ber is shown at E in Figures l1, l2 and 13. In this
event a long wooden or steel plate 103 may "be
fastened to the ?nishing machine A, or the plate
I03 may be supported on legs (not shown‘) extend
ing to the floor. In either event, the plate I03 is
supported in rigid position under the-web 16 of
fabric to be slit, with the cutter discs in trans
verse alignment with the cutter discs 41a .on the
edge trimming members B and C. ‘The plate I03
is disposed transversely of the web I6. It will
be understood that the multiple slitting ‘member
E is used in conjunction ‘with the edge trimming

plates are supported above. the plates I03 by ‘
brackets I25 the bottoms of which are fastened

in the plate I03 and these slots are parallel with
the pairs of bearing slots I08, IIO. By loosening
bolts I26 the shoe plates :I24 are free to slide when ‘
the cutter discs IIB are adjusted.
In the single ,slittting member D and the mun
tiple slitting member E it will be seen that their
assembly does not use the sharpening wheels nor
the cutter guards like in the edge trimming mem
bers Band C. In the multiple slitting member
E the assembly does not swing in and out of cut
ting engagement with the web It. The design of
the parts of the multiple slitting member pro
vides the proper position of the cutter discs II6 ,-.
with respect to the web I6 for cutting purposes.
