WEB OUTTING MECHANISM.
Specification of Letters Patent.
Patented May 25, 1915.
To all whom it may concem:
Be it known that I, ABRAHAM Novrcn, a citizen of the United States, and a resldent of New York, boron h of Brooklyn, 111 the county of Kings and State of New York, have invented certain new and Improvements in Web-Cutting Mechanrsms, of which the following is a specification.
This invention relates to web cutting mechanism and has for its object to provide means of the class specified, simple in construction, efiicient in operation, and adapted for operating upon a moving web.
With these objects in view my improvements comprise features illustrated in their preferred embodiment in the drawings accompanying this specification, wherein- Figure 1 is a front elevation of my improved cutting mechanism; Fig. 2 is a sectional side elevation on line 2--2 of Fig. 1, 100 in the direction of the arrow thereof, an showing means for feeding a web toward and away from said cutting mechanism; Fig. 3 is a fragmentary sectional elevation on line 33 of Fig. 1; Figs. 4 and 5 are fragmentary sectional elevations respectiveiy, on line 4-5 of Fig. 1, and successive steps in the operation of my improved mechanim Before describing the invention in detail I desire to have it understood that the invention is not limited to the particular construction and arrangement of parts which I have illustrated and shall hereinafter describe, and that various changes may be made in the mechanism shown without departing from the spirit or scope of the invention, and that the phraseology which I employ is for the purpose of description and not of limitation.
My improved web cutting mechanism comprises a pair of opposite, coacting cuttars, each of which is mounted on an am's eccentric to a fixed axis, and means are provided for revolving those eccentric axes about their fixed sues respectively, and for rotating the cutters on their eccentric axes in such directions and at such speeds of 1-0 tation as to constantly maintain those cutters normal to the path of the web therebetwecn. By this means said cutters are caused to advance in the direction of the movement of the web and to constantly maintain the most advantageous cutting relation to one another. For coaction with said cutters, I provide feed rolls for advancmg the web at the same speed as that of the forward movement of said cutters during their coaction and which speed of movement is governed by the amount of eccentricity of their eccentric shafts.
Referring now more particularly to Figs. 1 and 2, I provide upper and lower cutter heads 6 an 7 respectively, being opposite duplicates in than general features of mounting and movement. Therefore, a description of the mounting and movement of one thereof will sufiice for both.
Referring to cutter head 6, said head is provided with cylindrical portions 8 and 9 at opposite ends thereof, rotatably mounted in rotatable carriers 10 and 11 respectively. Said carriers 10 and 11 turn freely on studs 12 and 13, fixed in side frames 14 and 15 'vel The common axis of portions 8 and 9 o cutter head 6 is eccentric to the common axis of studs 12 and 13. For rotat' ing carriers 10 and 11 in unison, I provide those carriers with equal gears 16 and 17 respectivel and which gears are driven from canal gears 18 and 19 similarly fixed to heat 20 and 21 respectively, carrying cutter head 7. Gears 18 and 19 in their turn are driven by gears 22 and 23 respectively, fixed to shaft 24 rotatably mounted in bearings in side frames 14 and 15. On cylindncal portion 9 of cutter head 6 and disposed between said cutter head and carrier 11, is fixed gear 25; also fixed to the-inner end of fixed stud 13, is gear 26 equal in size to gear 25. Said gears 25 and 26 are actu ated by intermediate gear 27 turning freely on stud 28 fixed to head 11. Thus, when carriers 10 and 11 are rotated in clockwise direction on the common fixed axis of studs 12 and 13, Fig. 2, head 6 will be rotated in anti-clockwise direction on the common eccentric axis of its ends 8 and 9, and, as its gears 25 and 26 are of the same size, said cutter head 6 will be maintained throughout its planetary movement in a constant angu larrelation to the fixed parts of the machine. Cutter head 7,. being similarly mounted and actuated, will, during its planetary mo ement, maintain a similar i constant angular relation to the fixed parts of the machine and said cutter heads will, therefore, move and be maintained in parallelism with each other.
On either side of cutter heads 6 and 7,
Fig. 2, and normal to the common plane through the fixed axes about which those cutter heads move in circular orbits, I provide tables '29 and 30 over which a web or sheet may be fed between cutter heads and 7. To the right of said cutter heads, Fig 2, I provide feed rolls 31 and 32 for advancing the web toward the cutters in said heads, and on the left side I provide rolls 33 and 34 for removin the leading end of the web after it has been severed by my improved mechanism. Said two pairs of rolls are provided with the usual gears to cause them to properly coact and said gears are of such a character as to cause rolls 31 and 32 to have the same surface speed as the of advancement of the cutters during their coaction, and rolls 33 and 34 are driven at a slightly increased speed so as to take away the severed portion of the blank more rapidl than the speed of travel of the web.
tter heads 6 and 7 are provided with coacting cutters respectively While said cutters may be of any of a variety of characters, I preferably fix to the upper face of cutter head 7 a flat horizontal cutter 35, having a cutting edge 36 parallel with the axis of said cutter head. Adjacent to cutting edge 36 and preferably in the same plane as the upper face of cutter 35, I pro vide head 7 with a table-like portion 37 for purposes hereinafter described.
Cutter head 6 is provided with cutter 38 for coaction with cutter 35, and said cutter 38 is seated at its upper edge against abutment 39 in said cutter head. Said cutter is, however, free to yield sidewise in one direction against the pressure of springs as 40. Cutter 38 is provided at one end thereof beyond the line of cutting, with a downwardly reaching born 41 having a beveled face for engagement with one end of cutter 35, whereby, as said cutter 38 is about to pass into engagement with cutter 35, it is guided to accuracy of position therewith by the engagement 0 said horn 41 with the end of said cutter 35. By this ment a slight inaccuracy of coaction between cutter heads 6 and 7, due to backlash of gears or to any other cause, is corruted, and cutters 38 and 35 are always guided into coaction in predetermined relation. Cutter head 6 is preferably provided with a pair of resser feet 42 and 43, the former located to the right, and the latter to the left, of cutter 38, Figs. 2, 4 and 5. These preser feet are urged downwardly against sto s in said head by springs as 44, and are cient for gripping the web against the upper face of cutter 35 and table-like portion 37 of head 7, on opposite sides respectively of cutter 38, just prior to the coaction of that cutter with out ter 35, Fig. 4. Said resser feet thus retain the web in control during the cutting operation. After the cutting has been completed,
