Definitions
- an air doctor device of the character described having an air emitting slot defined by elongated cooperating lip members, with adjustability being provided not only as between the lip members but also independently or mutually with respect to a backing roll or other surface on which a stream of air emitted through the slot is intended to impinge.
- each of the lipmembers is adjust- Patented June 14, 1960 ice able independently with respect to the surface ,to be doctored.
- a further object of this invention is toprovide, in an air doctor device of the character described, independently and individually adjustable lip members defining therebetween a slot for the emergence of an air stream to impinge upon asurface to be doctored, with each of .the lip members beingfadjustably movable with respect to the source of air in the air .doctor and including as a part of its adjusting mechanism asealing member forpreventing escape of air other except through the slot defined by the lip membersand as a stream to impingeruponthe surface to be doctored.

- an air doctor device ofl'the character'to'which lthisin'vention comprises an .elongated'pipe mountedgenerally as indicated in Rig. 1 with respect to a backing roll 11 ofa conventional paper coating machine, With'a'paper web having a coating thereon' to be doctoredbeing indicated at 12.
- the mounting of the air doctor'across the'coating machine is not shown in detail, and it may be satisfactorily supported at its ends as by endbosses. 13 'in suitable supporting brackets 'or 'means'such, for-example, asdisclosed in the above patent and pending application. 7
- The-pipe IO'forms'anair chamber closed by a flange 14' at each end, and one'orb'oth of the endtbossesfll which form parts of the flanges 14 is hollow for the introduction therethroughof a supplyof air under pressure to the interior of the-pipe 10.
- the air stream'from :the holes 15" is controlled by'a pair of elongated-and converging 'lipmembers and 21 which form'a nozzle defining'thereoetween a relatively narrow slot 22"fordirecting the stream of air to-impinge with'the required velocity and force on to the 'surface 12 to be doctored.
- the lower lip-member'20f' is shown as a generally'flat plate, but theupper' lip'member 21' includes a flange 23'integralwith or weldedtoa reinforcing strap.24 to whichthe lip member 21 issecured by a plurality of 'cap screws25, and bracing ribs 26 are welded to. thefiange 23.and.plate24 at spaced locations therealong.
- Thisupper lip assembly alsoincorporates means. for flexing the lip member zlyparticularly to assure accurate alignmenrof the-workingedge of the lip.
- Such adjusting means include-a-plurality of set screws 27 threaded through the 'plate' 24'--for: engagement with the lip 21,and such flexing-of the :lip is also facilitated by the groove 28 bores 32 in the pipe.
- V An air doctor device of extending longitudinally of its upper surface.
- the lip members 20 and 2.1 are mounted on the pipe generall y'in the positions shown in Fig. 1 and in such relationwith the .holes inpipe- 10 .as todirect the streamof airfrom these holes through jthe;slot 22 for impingement in the desired manner. and direction on the web surface 12to be doctored.
- themountings of the lip members and 2 1 in accordance with the invention incorporate special provision for adjusting and controlling the position of each of the lip'members with respect to each other and to the web surface.
- the lowerlip member 20 secured to the underside of the pipe 10 by a plurality of screws which pass freely through the bores 31 in thelipmember 20 and are threaded into receiving the full length of the lip 21 in retaining grooves 34 and 35 in the opposed surfaces of the lip member 20 and the pipe 10 to form afulcrum about which the lip member 20 can be rocked.
- Such rocking movement is effected and controlled by a plurality of set screws 36 which extend through the lip member 20 along its back edge for 7 adjustable engagement with the wall of pipe 10 and thus cooperate with the screws 30 in the rocking adjusting movement of the lip member 20.
- ' .1 is 'a dust seal.
- a similar adjustable mounting is provided for the lip member 21 and includes capscrews 40 passing freely 7 through the flange '23 into tapped bores 41 in the pipe10.
- the fulcrum rod 44 extends substantially the full length r of the lip member 21 in retaining grooves 45 and. in
- either or both of the lip members 20 and' zl may be ad- -f jus'te d with great accuracy to the proper relation with 1 other lip member and the surface 12 to bedoctored, ,7 and it will benoted that the mounting construction of the invention facilitates adjustment of the upper lip member- 21 into an overhanging relation with the lower lip member 20 by the preferred range of several thousandths 'of an inch in order to direct the flow ofair downwardly V 7 against the surface 12 and thereby to aid in keeping the i structions of the invention is that all adjustments are made from outside the pipe-10 and thus require minimum time and dismantling of'any of the associated equip- A rod 33 extends substantially.
