SLITTING MEANS.
Application led August 25, v192i). Serial No. 405,997.
This invention relates to means for slitting a -fabric' of exible material into Sections, and has more particularly reference to a so-called score-cutter mechanism.
The invention consists of the hereinafter described features of construction, arrangement of parts and coordination of elements, a preferred embodiment of which is disclosed in the accompanying drawings.
.In the drawings:
Fig. 1 is a fragmentary front elevation showing a plurality of score cutters, embodying the invention, acting on a web section. v x
Fig. 2 is a Vertical sectional view on the line 242 of Fig. 1 showing' the parts in the position they occupy durmg the normal operation of the-machine.
Fig. 3 is a view similar to Fig. 2 showing the separator thrown out. I
Fig. 4 is a transverse vertical sectional view on the line 4 4 of Fig. 3.
Figs. 5 and 6 are detail views showing modified forms of separators.
The general type of machine to which this that shown in Patent No. 1,076,189 and application for Patent Serial No. 205,840 in which score cutting members engage a hardened cutter roll which may be the first rewinding drum or a separate member.
As here shown, 1 and 2 indicate surface rewinding drums that act on the coils of slitted sections on a rewinding shaft (not shown). Preferably, there is also associated with this construction a top pressure roller above the rewound material in a manner well understood.
3 is a cutter roll consisting of a core shaft and outer hardened sleeves in a manner well understood.4 4 is a movable support here shown as a hollow rockshaft similar to that disclosed in applications for Patent Serial Nos. 205840, 283497 and 256447. On
invention is more particularly applicable isA this lrocking support is mounted one or more carrying members 5 that are slidablyl ad- ]ustableon a dovetail surface 6l and which may be secured in position by means of setscrews 7, or otherwise. Each carrying member- 1s provided with open bearings 8 in whlch a cutter holder 9 is pivotally mounted, said 'cutter holder rotatably mounting a score cutter 10. 11 indicates a spring having one end anchored on carrier 5 and its other end presslng against cutter holder 9 so as to normally urge the cutter against the cutter roll, o r normally urge the cutter holder in one direction. The tension of this spring may be varled by means of member 12. 13 lndlcates a separator holder pivotally supported on pin 14 between arms l15 and ad- Justably carrying at its upper end a separator blade 16. Separator holder 13 carries at lts lower end an adjustable screw 17 provided with nut 18 and a spring 19 surrounds 17 between nut4 18 and abutment surface 20 on the cutter holder. Spring 19 normally urges separator holder into the position shown in Fig. 2, that is, into engagement with the slitted sections, the movement in this direction being limited by stop 2l. 22 is a latch for holding the separator in inac` tive position and 23 is a foot pedal on the separator holder.
It will be understood from the foregoing that by rocking support 4 to the right in Figs. 2 and 3, score cutter 10 will be brought into engagement with the cutter roll and the, separator will be brought in-to engagement with the slitted sections, and that, owing to the spring 11. the movement may be continued after the cutter comes in contact with the cutter roll, the effect being to increase the tension with which the: cutter engages the roll. This action, of course, alfccts all the cutters alike, the individual tension of each cutter being adjusted by means of member 12. Ii' it is now desired to throw out the separator m0- ment-arily, pedal 23 is slightly depressed to the extent indicated in full lines in Fig. 3, and if it is desired to maintain the separator in its tripped position, pedal 23 is depressed still further as indicated in dotted lines in Fig. 3 and latch 22 is moved into the dotted line position where it en ages with the hub of the cutter holder. the parts are released, the action of spring 19 will restore the separator to its original position. Tf 1t is desired to throw out both the separator and the cutter, pedal 23 is depressed until Cil the end of' member 17 engages abutment surface 2O thereby tilting the cutter holder around its pivot 8 against the action of spring 1l. lt will bc understood that in this way, each cutter holder may be thrown out independently of all the other cutter holders and independently of any movement of rocking support 4'.
The advantages of the above construction will be understood from the following: the cutter and cutter roll will ordinarily cleave the material, the function of the separator being to sever any remaining threads or fibres and` under certain conditions, to spread adjacent slitted sections. The 'latter, therefore, acts on the material after the cut-ters have performed their functionlln threading the web through the machinethe cutters are thrown out all the way by rocking member 4 and, when thrown in, an unsevered web portion will he opposite the separator. llt is therefore necessary that the cutters be put into action before the separators or, conversely, that the action of the separators be deferred until slitted sections have been' produced by the cutters since, otherwise, the paper might tear. Again, during the operation of the machine, it is desirable to be able to trip either the separator or both the cutter and separator without affecting the other cutters and separators and the construction disclosed permits of this being done. This is especially useful when a portion of the web is torn out before reaching the slitting machine when, at times, it may be advantageous not to slit, for a slight distance, one of the outermost sections. The
above are' typical examples of the manyconditions that arise during the operation of the machine when quick action is necessary on the part of the operator. vThe parts disclosed are susceptible of instant operation.
rThe cutter embodies in itself novel anu valuable features of construction. As shown.V
in Fig. 4, 24 indicates a shaft mounted in bushing 25 of the cutter holder. This shaft has a flange 26 and a reduced portion 27 and a still further reduced portion 28. 29- is a housing within which is roller bearing 30 held in place against flange 26 by cap 31 and nut 32 on stem 28. Housing 29 is provided with a circumferential upstanding flange 33, and the cutter 10, which is Iin the form of a ring, is bolted to flange 33 by means of bolts S-l. This 4arrangement admits of easy removal of the cutter when it requires grind-A ing or other manipulation. Also easy access may be had to the roller bearing by removrecano@ ing cap 31, and the lcutter can be removed without disturbing the anti-friction device.
The separator may take many forms. Thus, instead of being a mere blade, it may have a ball shaped member 35, as indicated v the separator independently of the score cutter.
2. Means for slitting a web of flexible material into sectionscomprising: a cutter roll, a score cutter engaging therewith, a separator engaging the slitted sections, a
support for moving the score cutter and the i separator toward and away from the cutter roll and the sections, and means for successively throwing out the separator and the score cutter independently of the movement of the support.
3. Means for slitting a web of flexible material. into sections comprising: a cutter roll, a score cutter engaging therewith, a separator engaging the slitted sections, a support for moving the score cutter and the sepalrator toward and away from the cutter roll and the sections, a pivctally supported cutter holder mounted on the support, means for urging said holder toward the cutter roll, a pivotally supported separator holder mounted von the cutter holder, and means for urging the separator holder toward the slitted sections.
d. Means for slitting a web of exible material into sections comprising: a cutter roll, a score cutter engaging therewith, a separator engaging the slitted sections, a support for moving the score cutter and the separator toward and away from the cutter roll and the sections, a pivotally supported cutter holder mounted on the support, means for urging said holder toward the cutter roll, a pivotally supported separator holder mounted on the cutter holder, and means for urging the separatorholder toward the slitted sections, means for swinging the separator holder on its pivot to throw it out and for thereafter, bythe continued movement of the separator holder, swinging the` cutter holder on its pivot tothrow it out.
