EDUARD FELIX MLLER, OF LEIPZIG-AUGER, GERMANY;
CUTTING MECHANISM FOR PAFER-BAG-MAKIG MACHINES.
Specication of Letters Patent.
Patented Apn'i 27, 1909.
Original application filed January 12, 1907, Serial No. 362,019. Divided and this application filed February 3, 1908.
Serial No. 414,101.
To` all 'whom it may concern: l
'Be it known that I, EDUARD FELIX ML- LER, a subject of the King of Saxony, residing at Leipzig-Auger, in Germany, have invented a certain new and useful improved Cutting Mechanism for Paper-Bag-Making Machines, of which the following is a specification.`
This invention relates to cutting apparatus for use in paper bag making machines more particularly for bags produced from a web y a continuous series of operations due to a continuously rotating drum and accessory rotating machine parts, for example, as illustrated in my application for patent Serial Number 352019, .tiled 12th`January 1907.
The cutting apparatus is illustrated in the annexed drawing in which- Figure 1 is a side elevation of the same showing also partof the drum and gripper-s thereon. Fig. 2 is a rear elevation of the cutting apparatus. Fig. 3 avertical section thereof. Fig. 4 is a horizontal section. Figs. 5 and 7 are detail sectional views illustratin two'methods of cutting and Figs. 6
- and 8 illustrate the forms of cut made thereby. Fig. 9 is a perspective view of a bag zwi-th edges -cut as 1n Fig. 8.
The. paper tube passes between the feedrollers 1 and 17 and thence to the cutting mechanism, the tube being cut by the knives 19 at the moment when the front end of the tube ise'ngaged by the grippers 18 (Fig. 1).
The cutting mechanism comprises the endless chains 24 traveling 'over the sprocketwheels 20 and 21, and guide rollers 22 and 23, the knives 19`being attached to these chains. The velocity ,of the knives is considerable compared with that of the aper tube, in order to secure a ra id and c ean out. lThe rollers' 22y and 23 guide the chains in such a' manner that the knives vact in the manner of shears.` The guides 25 (Figs. 4- 5 and 7) serve to insure perfect steadiness of the knives during lthe cutting operation, the knife-holders 27l being provided with lanti- `friction rollers 28 working in the grooves 26 ed in the frames 30.
sides of which are of eqlpal length, or the cutting operation may ta e place above or b'elow the guide-bar 29 (h ig. 7) so that one side of the blank has arounded edge overlapping the edge of the other side (fr ig. 8). The sprocket- wheels 20 and 21 are mounted in the frames 3() pivotally connected to the toothed segments 32 mounted on the shaft 31, the said segments being in mesh with the toothed wheels 34 fixed to the shaft 33, so that by rotating thelatter the segments can be raised or lowered to regulate the cutting position of the knives 19 relatively to the guide-bar 29. After adjustment the segments 32 are made fast to the frame 10 by means of screws 35.
Pivotally connected to segments are the two flat levers 36 which are adapted to be fixed to the frame 10'by means of screws latter is provided. To each lever .36 is bolted a toothed rack meshing with a pinion 38 I fixed to the shaft 39, the latter being mount- Rotation of the shaft 39 therefore rocks the frames 30.011 their pivots and allows of adjusting the distance of the knives from the feed- rollers 16, 17. This arrangement allows of exactly regulat-` ing the length of paper-tube outside the ripper- bars 40 and 66 when the pa er is cut, from this projecting part of the )lank the bottom of the vbag is subsequently formed. After adjustment the frames 30 are made fast to the levers 36 by means of the screws 41, the said levers b'eing fixed to the frame 10 in the manner already'describevd. The total length of the blank out is regulated by the circumferential velocity of the feedrollers 16 and 17, which are driven by means of suitable variable speedear. The velocity of the chains 24 and mives 19 is constant, the sprocket Wheels 21. being driven by means of the shaft 43 and toothed wheels 42 in'mesh with the toothed wheels 44 fixed to the shaft `45, the wheel 46 fixed to the latter is driven from the driving shaljt 47 by means of the toothed- wheels 48, 49 'and 50.'
l/Vhat I claim as my invention and desire to secure by Letters Patent 0f the United States is 1. A cutting mechanism for paper bag making machines comprising two continu-y ously moving knives passing each other so as to act in the manner of shears, and chains, bands or ropes, on which said knives are mounted, means for driving the chains, bands o r ropes and guides for guiding the knives during the cutting-oi? process.
2. A cutting mechanism for paper bag making machines comprising two continuously moving knives passing each other so as to act in the manner of shears, and chains, bands or ropes, on which said knives are mounted, means for driving the chains, bands or ropes, guides for guiding the knives during the cutting-off process and means for adjusting the cutting-off mechanism in the vertical and in the horizontal direction.
3. A cutting mechanism for paper bag making 'machines comprising tWo knives 19 -38 on shaft 39 to regulate the cutting relatively movable to act in the manner of shears, knife holders 27 provided with antifriction rollers 28 Working in grooves 26, guides 25 serving to insure perfect steadiness of the knives during the cutting operation, continuously movable chains,l or bands 24 to which said knife-holders are connected, gears 21, gears 20 and guiding Wheels 22 and 23 for said chains or bands, frame 30 carrying gearsv20, 21 and Wheels 22, 23, lever 36, shafts 39, 31 and 35 toothed rack and pinion osltion Vof the knives in the horizontal dlrection, and segment 32 fulcrumed on shaft 3l and pinion 34 on shaft 33 to regulate the cutting position of the knives 19 relatively to the guide-bar 29 in the vertical direction.
In Y Witness whereof I have 'signed this specification in the presence of twotwitnesses.
y EDUARD FELIX MULLER. Witnesses: ERNST JULlUs WAGNER, RUDOLPH FRrcKE.
