fOne-or more counter earns 96 are mounted on a part of 'the press ll'which moves in directtcorrelation to the lineal surface movement of the web 12.v Thus, for'example, a

,cam 96 may take the form of a protuberance on any drum or cylinderxwhich drives or is driven by the web Thus, 7 impulses for the counter may be taken fromvany active drawing or feeding roller which rotates in correlation to.

the web movement to reflect web length units, and this 1 structure .may be integral with the press or maybe an attachment, -The, impulse may be taken from .a point at the folder 32so as to get'a pluralor parallel count fora'number of webs simultaneously, and 'a break in any web"wil1 indicate that that count is tdbedisregarded.

adjusted to read in lineal distance preciselyequated to the paper contacting'periphery of the cylinder 28.- As

the press 11 operates and the web 12 travels therethrough,

j the counter 50 ,will add the'total length of the web;

The autopasteru'nit 17, ofzthe system 10 is locatedon the press 11 and is connected at its" terminals 100 and l 101 to: conductors l02'and 105, respectively. 'When the roll 14 becomes exhausted,' it will be connected, to the beginning of roll 1412 by autopaster- 16 which usuallyis 'electrically' operated byan impulsein circuitllt) which powers solenoid112 and shiftsrthe autopaster arm 116 to which'is'connected known structure such as 1 brush" powerssolenoid 114whosepawl armature 115 advances i the selectorswitch 108 ito-the ne'Xtposition so that con ductor 106 now feedsj conductori64b and; counter 50121 Thistwill continuein-like manner-for'the desired number of rolls 14. and counters 50in the group or'run. After... the group or run is completed, the results on the counters 50 may be-read and recorded and may be automatically printed, and thecounters'reset. This is accomplished by 7 manually closing the reset switch'97' which first completes the circuit to the printing solenoid 78 via conductors 102, 118 and 103; and/then completes the circuit to. the reset winding 74, insolenoid 72, via conductors 1 20 and 103,-as well as the circuittto the'selectorswit'ch 108 return solenoid 109 via'conductors 122. and 103-. When ener gized, solenoid 109 pulls armature 109 thereby disengaging pawl 113 which allows spring 124 to rewindrthe switch arm in switch 108 to its original-starting position.

The web .break detector unit; 15 of the system 10 is located on the press'll' and is counectedat its terminals 130, 131 and i132 Ito conductors- 102, 134 and 136,- respectively; Any number ofunits' 15-may be used, connected in series so that .the greatertlie number: of sensing points, the'less the probability ofa break to be undetected and/or the more nearlyaccurate will be 'the readings.

' Switch has an arm 161whi'chis fixed on shaft 107, as is thearrn 162 of switch 108,so that said arms move in unison. Therefore, inthe event of a web rupture, a circuit isrcompleted, through switchsl46, conductor 148,

switch 150, conductors 152 and 134,- arm 161,- conductor,

164, winding 88, and conductor 103. This pushes cradle arm :87; dow'nas previously described and switch 83 closes a circuit between conductor 102, indicatormeans '48, and conductor 103, activation will be in unison. lnflrepair,

usually the damaged section of'theaweb is cutout and theremaining free ends are joinedr This makes the reading on 'thatgparticular roll inaccurate v Because the rod 70 :(FIGUREj4) is frictionallyretained iii-shifted positions thereof,- the means 48 will stay lit, and ribbon 82 andrpane 84 willstay'injthe -.disregardfposition until reset switch 97 is closed. I

Turning now to the second embodiment 0t theirivention, as shown in FIGURES: 6 and 7, ,for the purpose of 6 0,

avoidingneedless repetition certain. of the parts corresponding tothefirst embodiment are'given the same reference characterswith the addition ,of 'a suflix, e. V

The second embodiment differs from the-*firstembodiment principallyi in provision of a singlecounter. without automatic reset, imanual resettingbeing-provided. E, a

- Thus after a reset (the closing of switch 971?), switch 156eis closed starting motor 1542; At theend of thefirst roll, the autopaster unit 17e'sends an impulse to solenoid 78; causing; the total .ithen appearing on they counter 50::

to print on 'tape-44ej a'nd this zwill repeat, at'each roll end; Ifra break has occurred, the print out will appear .in red, inKthe tapef'f44e and the indicated linear 1 distance between the 'red] number, and thejnextj preceding 'num-r berhwill3be;disregarded, ijAt' the end ofi the'run orlroll 1 75 group, switch '97 is againfc losed, whichiresets the sy s5 I The elewith automatic'reset, manual resetting being also avail-- able.

The automatic reset circuit includes a switch 17i which is mounted on the platen 76i, andwhich closes the circuit. during downward travel of the platen 76 i after the printing impression has been completed. Switch 197i includes a pivotal coutactfinger 198i, swingable between two detents. The upper surfaceof finger 1198i has an insulating member which prevents contact of the conducting portion199i during upward travel. During downward travel the portion-199i wipes the relatively station- I wish it to be understood that I do not consider the invention limited to the exact details of structure shown and described in this specification, for obvious modificatons will occur to a person skilled in the art to which the invention pertains.

I claim:

1. A system for web length measurement for use with a continuous web treating machine having web feed means and means to interconnect web portions, comprising: measuring means on said web feed means supplying an impulse for a predetermined length unit of said web; a weblength unit counter; said measuring means actuating said counter; said means to interconnect being connected to said counter to stop the counter, whereby total continuous Web length may be read off said counter.

2. A system for web length measurement for use With a continuous web treating machine having web feed means ary contact point 200i, which is resiliently mounted on spring 201i.

Thus in the print when each roll is consumed, and the reading will be the length of, each roll as consumed .(except when the disregard circuit causes printing in a different color).

Turning to the fourth embodiment of the invention, as seen in FIGURES 11 and 12, for the purpose of avoiding needless repetition, certain of the parts correspondingjto theprior described embodiments are given the samereference characters withthe, addition of a suffix t f I Where the web speed is relatively fast and the counter reset time is not instantaneous, a loss in counting length may requirerapid shifting between two counters with the reset taking place in one counter during inactivity of the other counter. This is what the fourth embodiment I provides. 7

With the step switch 21 4t and the shifting switch 2102' in the position shown in FIGURE 12, the cams v961. act on switch. 1041 to intermittently close the circuit via conductors 642 and. 66t to actuate counter t.' A pulse "from the autopaster. unit: 1.7t, via conductors 212t' and 213i, energizes step relay 2141, which shifts the line voltage previously connected to winding 216t of switch 21% (viav conductor 240!) to winding 218i (via conductor 242t); causing switch210t. to move to the. right in said figure. j I i I -This does four. operations. Arm 2201, disconnects counter 50)." and connects counter 50btin circuit with switch 104t, and conductors 102L641? .andeet. Arm 222i moves to disconnect printer solenoid 78t from the circuit 102t, i, '101t, 118i, 119t, 103tto' connect solenoid 78b! via conductor 119bt. The contact 22423 is elongated-toallow sufficient timefor solenoid 78t to print, but by the time arm 222i reaches contact 2261, the pulse has discontinued and solenoid 78b't cannot print. Arm 228t, which'via conductors 1021f, 134t, 164t and 103t had completed the circuit from web break detector unit 151. to disregard winding 88t, now shifts to 164btto complete the circuit from unit 152 to disregard winding 88bit. Arm 230! (after arm 220i has decontacted conductor 64!?) closes the circuit 102i, t, to reset winding 74t by contacting the upper contact on the switch cam 231t (FIG- URE 12A), so that counter 50! maybe reset independently of the initiation ofoperation of counter 50kt.

W The next autopast'er pulse will travel to step relay 2142', causing it to sendthe line voltage to winding 2161?, via conductor 240t, thereby pulling shifting switch 2101 back to its original position in FIGURE IZ. On its trip backthe resilient pivotal finger 2321 on the end of arm 230:? contacts the lower conductive surface of switch cam 231t to provide resetting of counter 50bit.
