It being understood that-pipev and the channels coni'iectedthereivith are under exhaust tension diaphragms 78, 79 are at rest as shown an ai) main valves 70, `71 are seated by atmospheric pressure closing openings 68, 69 and permitting air to enterboth pneumatica 36, 7 (Figi 1i) throughopenings 72, 73, channels 66, 67 and ducts 50, 51, all respectively. 25 Said diaphragme` 78, 79 are at rest because bothsidesof each thereof are subject to the samejtension; ontheir upper sides thi- ou h channels 64 and 61 and on their lower si es f throu hvchannels and 62 and openings 84, $0 85u11 channels 80,81 all respectively. Also, diaphragms 88 89 and valves 86, 87 are at rest as; Shown said Fig. 5 because said diaphragms are under equal tension on both sides thereof respectively through channels 64,' 62 andibleed @ holes 92, 93.

If'now a porti-on of web W narrower than the distance between the outer edges of o nings 24 and 25 passes thereover (Fig. 7l),e it will permit air to enter both of those passages and thence to the underside of both diaphragme 88, 89 whereby, by means alrea y described, valves 70, 71 will both be raised allowing tension to act on both pneumatics 36, 37. Said pneumatics being thus in equilibrium under tension no endwisc shifting of rolls 2, 4 will occur, any more a than when said pneumatics were in equilibrium under atmospheric pressure. If now said narrow portion of web W deviates widthwise'from its normal and symmetrical 90 path of Filg. 7, as for instance to the right as shown in ig. 8, inner guide opening 26 will be uncovered ( outer guide openings 24, 25 remaining uncovered) thereby admitting air through duct 46, channel and opening 108into chamber 106 below diaphragm 104, causing said diaphragm to rise abruptly, driving valve 98 upwardly, thus closing passage`97 against the entrance of air from chamber 95, duct 45 and uncovered guide opening 25, to chamber 91. Thereupon the exhaust from 'channel 62 throu h .bleed hole 93 will equalize the tension on sboth sides of diaphragm S9 allowing the air pressure in n channel 83 to drive valve 87 downwardly, closing Ythe passage from said air4 channel 83 to channel 81I and opening the passage from exhaust channel 62 to said channel 81. Diaphragm 79 is thus under equal exhaust tension on both sides thereof and the air pressure from above will drive main valve 71 downwardly, closing the passage from exhaust channel 61 to channel 67 and admitting air through opening 73, channel 67 and duct 51 to pneumatic 36 destroying the equilil iium of tension previously existing in pneumatics 36 and 37 and permittin the exhausttension in pneumatic 37 to,fco apse that pneumatic, thereby pullin rod 19 and rolls 2, 4, carrying web W, to t e left (Fig. 160 1), whereby said web is restored to its nor-- mal path of travel -covering both guide openings 26, 27V as in Fig. 7 and said pneumatics 36, 37 are again in equilibrium under Y tension. v
