The working up of printed sheets in cutting machineswith automatic feeds of any kind encountered hitherto great difliculties in so far as it is practically impossible to maintain the printmg properly spaced with relation to edges of the several strips, labels and the like. If, therefore, sheets printed with strips or labels have to be subdivided in cutting machines by means of automatic 1o feed, it is possible to obtain, by means of the automatic feeds of known type, strlps and labels of accurately uniform size, but when the cutting line has to be adapted accurately to the printed matter, the known automatic 16 feeds fail, as they are adjustable only to one and the samesize, or can be ad usted to a different size only gradually by automatic adjusting of the feed. The cuts are made at accurately equal distance the one 20 from the other, or this distance is gradually increased or decreased, however not accurately along the lines determined by the printed matter.
The roblem has therefore to be solved, to
2 make ii possible to automatically interrupt the automatic feeding of the cutting material at any desired point, in order that the cutting material may be automatically subdivided into strips or labels of any desired chan ing size. For the solution of this prob em a locking element, for instance a ratchet pawl, is provided in the automatic feed, which maintains the power transmitting means as, for instance, a clutch of an automatic feed for the cutting material in the engaged position; until it is automatically disengaged by any means, whereby the power transmitting means of the automatic feed is disengaged and the feed interrupted.
4 The automatic disengaging of the locking element and therefore the interrupting of the feed can be effected in various manners. For instance marks may be printed on the sheets to be printed, situated at points,.at 4 which the subdividing cuts are to be made. At the automatic feeding of the material to be cut, the material passes with the marks under a light sensitive element, for instance a photo cell. If such a printed mark comes into the range of the light sensitive element,
this element is operated and excites an electro-magnet, which in turn disengages the locking element of the power transmitting means of the automatic feed. Instead of printed marks, current conducting marks, 55
characteristics or elements may be located on the sheet at the points, at which the out has to take place. The
material to be cut passes at the automatic feeding with these current conducting marks under two cur- 8 rent conducting feelers, which form the end poles of an electric circuit. If at the feeding of the material to be cut a current conducting mark arrives under the current conducting feelers, the electric circuit is closed,
and an electro-magnet is excited, which disengages the locking element of the clutch so that the automatic feed is interrupted. These current conducting marks need not be printed on the sheets; they may be arranged as adjusting marks on the band disk which effects the conveyin of the material to be cut, or on any other e ement travelling in proportion with the feeding'of the material to be cut, when they are adapted to be adjusted according to any desired cutting points, so that at the automatic feeding of the material to be cut it slides underneath two current conducting feelers or detectors and disengage thus electromagnetically the sists in that on a band disc stops are adjusted in accordance With the desired cutting points, which stops at the conveying of the pile of sheets, i. e. at the rotation of the band disc, move along a control lever and lift the same, whereby the disengaged mechanically.

On the table 1 of the cuttin machine, material 2 to be cut (Fig. 1) is yin the rear ed of which bears against a sad e 3, said sa dle ada ted to be moved forward and backward means of a band or cable 4 (Fig. 3), which operates in contact with a pulley 5. A worm 6 gears w1th the worm crown pulle 5, said worm adapted to be rotated in rig t hand or left hand direction throu h the intermediar of 0 en or crossed belts roin the fly wheel so t at the saddle 3 is moved forward or backward respectively. Above the material to be cut, which has nding to the desired cutting points' (Fig. 1), a li ht sensitive element 8 is arranged, under w ich the material to be out p :Q- A power transmittin means which, in the present embodiment o the in vention, consists in part of twov clutches 10 and 11 can be shifted for the forward and backward movement of the saddle by a hand lever 9. The clutch 10 for the forward movement of the saddle can further be enged by means of a roller lever 12, actuated E; a cam 13'of a crank spurwheel 14. If the forward clutch 10 is engaged by means of the hand lever 9 or automatically by the roller lever 12,. the fork lever 15 engaging the clutch is secured in its engaged position by a locking element 16' pressed by the action of a spri 17 against said fork lever 15, and the feed of the cutting material continues as long as this locking element 16 secures the fork lever 15 in its position. If the locking element 16 is disengaged, the fork lever returns into its inoperative position by the action of a spring 19 and disenthe forward clutch 10, so that the conveying of the cutting material is stopped.
The operation of the machine is as follows:
After the material 2 to be out has been placed on the rear table of the cutting machine and the li ht sensitive element is enagetl as regards ei ht, so that it rests lighton the surface 0 the material to be cut Fig. 2), the forward clutch 10 is engaged by and b means of the hand lever 9, secured in t is engaged position by the locking element 16 and the material 2 to be cut is automatically fed by the saddle 3 on the table (Fig. 32.
A source 0 light 36 mounted in the housing of the light sensitive element 39 (Figi1 6) throws through a gap 37 and throug a prism 38 a narrow ncil of light raiiiys u n the movin pile. e light thus re ecte is intercepte by the light sensitive element 39. As long as this reflected light falls ontothelight sensitive element 39, the grid 41 in the amplifier valve 40 (Fig. 7) is positive and current flows through the amplifier valve and maintains open a contact through the intermediary of a relay 42 inserted in the circuit of the amplifier valve (Fig. 7 As soon as however a mark a arrives in the range of the light gap on the material to be cut, when the material to be cut is sliding under the light sensitive element, the light gap' is darkened and no light can reflect an more. At this instant no reflected lig t strikes the light sensitive element and the grid 41 of the amplifier valve 40 becomes negative and thrott es the anode current of the amplifier valve. The relay 42 becomes thereby currentless and the contact 43 closes. B the closing of the contact 43 the circuit of the electro-magnet 18 is closed, and the electromagnet excited pulls back the lockin element 16, which secures the forwar clutch 10in the engaged position, whereby the clutch 10 is disengaged and the automatic feeding of the pile interrupted. The moved masses of the automatic feeding mechanism are thereby arrested by a brake 20 (Fig. 3). By the closing of the contact .43 the circuit of the electromagnet 21 is closed at the same time, and this electroet is excited, so that it disengages the magn loc ing lever 22, which has held the light -thus actuated throug .the gearing ofthe machine, crank 44 and pull rod 45 of the knife, so that this knife operates'to out at the point indicated by the mark a.'(Fig. 1). When the knife is ascending, a cam 27 on the crank spur wheel 14 returns, shortly before the knife arrives in its highest position, the light sensitive element 8 throu h the intermediary of an elbow lever 46 am the connecting rod'28 into its operative position, in which it is secured by means of the locking lever 22. At the same time the forward clutch 10 is engaged by the abutment cam 13 of the crank spur wheel 14 and by the roller lever 12 and secured in this engaged position by the locking element 16, so that the material to be cut begins again its forward movement. The knife is stopped in its highest position by a contact cam 29 on the crank spur wheel 14, which strikes a trip 29 to open the switch 29 and thus interrupts the circuit for the electromagnetic clutch 26 and disengages the same. (Figs. 3 and 7). When the saddle 3 arrives in its extreme forward position, a switch, operated by mechanism generally identified by the letter A, against which the saddle 3 strikes, interrupts all circuits so that all driving mechanisms are stopped. The saddle 3 is returned into its initial position by oscillating the hand lever 9 to the left, whereby the backward clutch 11 is engaged. The brake 20 is released by the engagement of the two projections of the fork levers l5 and 30 (Fig. 3
The interruption of the automatic feed, i. e. the disengaging of the locking element 16, can be obtained by any well known current conducting means instead of the marks a, on the points where the cut has to take place. Metallic inks are for instance used for printing these marks. In this case two juxtaposed current conductor feelers 32 (Figs. 4 and 8) may be arranged above the printed sheet instead of the light sensltive element 8, said feelers forming the end poles of an electric circuit and sliding on the pile 2. As soon as such a current-conducting mark arrives under the feelers 32 at the automatic feeding of the material 2 to be cut, the electric circuit is closed and the two electromagnets 18 and 21 excited which, on the one hand, disengage the locking element 16* so that the conveying of the material to be cut is interrupted and, on the other hand, pull back the locking lever 22 whereby the feelers are pulled back by the spring 23 and removed from the plane of movement of the knife (Fig. 8). The engaging of the electromagnetic clutch 26 and thereby the starting of the movement of the knife and the reengaging of the feeding mechanism and stopping of the knife movement are effected in a similar manner as at the use of the light sensitive element 8.
It is further possible, to obtain the disenaging of the locking element 16 mechanically. With this object 111 View, abutment cams 33 are arranged on the band pulley 5, adjustable according to the desired cutting points (Fig. 5), said cams striking at the.
automatic conveying of the cutting material, i. e. at the rotation of the band pulley 5, against a controlling lever 34 lift the same. By the lifting of this control lever, the locking element 16 is pulled back through the intermediary of a pull rod 35, and the feeding, as described, is interrupted. The engaging and disengaging of the electromagnetic clutch 26, as well as the re-en aging of the forward clutch 10 are efiecte in the same manner as described above.
