COATING MACHINE.
Application filed February 10, 1926. Serial No. 83,392.
My invention relates to coating machines, and particularly to that classof machine used in coating book papers, wall papers and some classes of fabric.
the coated surface.
The number of brushes and the quality of the coating preparation used has a decided bearing upon the quality of the finish of the material.
The principal object of my invention is to eliminate the rotary or vibrating brushes, and immediately after the material leaves the coating head of the machine I provide smooth face rolls for the purpose of distributing the coating preparation over the surface of the material being coated, and to produce an ironing effect upon the coated surface of the material, for the purpose of producing grade finish thereon. Other advantages and details of the a high invention will be more fully disclosed hereinafter and as illustrated in the accompanying drawings, in which:
Fig. 1 is a side elevation of my improved coating machme showing a web of material passing therethrough to receive a coating on both of its sides, and
Fig. 2 is a fragmentary side elevation showing a web of material passing therethrough to receive a coating on but one of its sides.
Referring to Fig. 1, a side frame of the ma chine is illustrated at 1, it being understood that such frame is duplicated at the opposite side of the machine, and 2 illustrates a supporting frame located at the receiving end of the coating machine, being provided with bearings 3 for the reception of a spindle 4 on which is mounted a roll 5, of the material to.
be coated.
The material passes from the roll 5 in the form of a web a, passing over a roll 6 journaled in a bearing 7 forming a portion of vertical extensions 8 of the frame 2. A roll 9 is rotatably mounted in a forked bearing 10 in the upper end of the extension 8, adapted to bear upon the web a as it over the roll 6.
and is passes An angularly disposed table 11 is provided adjacent the delivery side of the roll 6, and is supported by arms 12 projecting from the frame 2. As the material passes from the roll 6 and over the table 11, it is engaged by a festooning apron 13 adapted to move in a direction whereby the material is carried toward the frame 1 of the coating machine.
The apron 13 passes around a roll 14 rotatably mounted in bearings 15secured to the frame 2. The opposite end of the apron 13 passes around a roll 16 mounted in bearings 17, adjustable within brackets 18 secured to the receiving end of the frame of the coating machine. The festooning apron may be driven from any suitable source of power,and
at any speed desired with respect to the roll 6 to form festoons of the desired proportions. The web a, upon leaving the festooning apron 13, passes in a substantially vertical direction around a roll119 rotatably mounted on the frame 1, and between rolls 20, 21, 22 and 23 whose position m ay be varied with respect to the vertical, lane of travel of the web a for the purpose 6 applying tension thereon, and from the roll 23 the web passes over a 1 01126 rotatabl mounted on the frame 1. As shown in ig'. 1, the material is to receive a coating on both sides, and for this purpose spray nozzles 30 and 31 are positioned at either side of the line of travel of the web a, the web passing from the roll 26 between feed rolls 32 and 33 rotatably mounted in bearings 34 and 35 respectively, said bearings being vertically adjustable within the frame 1.' The rolls 32 and 33 co-operate to distribute the coating preparation evenly over the surface of the material.
The spray nozzles 30 and 31 are suitably connected by piping 36 to a pump 37 which in turn is connected by a pipe 38 to the bottom of a tank 39 adapted to contain the coating preparation and to receive the surplus thereof as the web a passes between the rolls 32 and 33, the tank 39 being open at the top for such purpose.
As the Web a leaves the coatin head of the machine, passing between the ro ls 32 and 33, it is engaged in the present instance on the bottom surface by a smooth face roll 40, positioned immediately adjacent the delivery side of the rolls 32 and 33. The web a is nextengaged by a smooth face roll 41 upon its upper surface and thereafter successively by 60 I flow of coating material is closed off from 'the spray nozzle 30 by any suitable means.
rolls 42, 43, 44, 45, 46 and 47 alternately engaging the web a on its upper and lower surfaces.
Each of the rolls 40 to 47 are provided with a shaft 48 journalle'd in a bearing bracket 49 slidably mounted on a pillar 50, forming part of the frame 1 of the machine. The
bearing bracket 49 in each instance is provided with an extension 51 on which is mounted a motor 52 of the reversible variable speed type, and the armature shaft of each of said motors is provided with a pulley 53 adapted to receive a belt 54 which passes around a pulley 55 secured to the shaft 48 of each of said rolls. The bracket 49 is also provided with an extending lug 56 having a threaded aperture into which extends a jack-screw 57 rotatably mounted at 58 in theframe 1 of the machine.
It will be understood that the bracket 49, pillar 50 and the jack-screw 57 in each instance are duplicated at the opposite side of the machine and in order to turn both of the jack-screws 57 simultaneously, and thereby raise and lower and maintain the respective roll in a substantiallyhorizontal plane, each of the screws 57 is provided at its lower end with a worm wheel 59, which mesheswith a worm 60 secured to a transverse shaft 61 rotatably mounted in bearings secured to the frame 1. At one end of the shaft 61 is provided a hand wheel 62 by means of whichthe shaft may be rotated.
The rolls 4()47 are adapted to be adjusted to receive a coating on both sides from the spray nozzles 30 and 31, and in this particular instance the rolls 4047 are rotated in a counter-direction to that of the movement of the web a. In this manner the ironing effect above mentioned is successfully obtained.
As shown in Fig. 2, the web a is adapted to receive a coating on but one of its faces, the web being led over the roll 26 and under a roll 26 rotatably mounted in bearings secured to the frames 1, 1, adjacent the roll 33 ter of rotation of said roll. In this manner the web a is carried below the spray nozzle 31, and thereby receives a coating on but one of its surfaces, it being understood that the In this case, where the web a receives a coating on but one of its sides the rolls 40, 42, 44 and 46 are driven in a direction cons1st-- ent with that of the travel of the web a, while the rolls 41, 43, 46. and 47 are driven in the counter-direction thereto, for the purpose of producing the ironing effect upon the coated surface and providing a support for the web adjacent its uncoated surface.
In each instance, after the web leaves the roll 47 it is engaged by a brush 65 on its upper surface and a brush 66 on its lower surface. These brushes are adapted to give a final finish to the coated surface before it is discharged from the coating machine. Each of the brushes 65 and 66 is secured to a transverse bar 67, mounted at each of its ends in a 'slidable bearing 68, adapted to a guideway 69 secured to the frame 1. The bar 67, with its respective brush, may be adjusted vertically by means of a screw 70, passing through :1 lug 71 on theguideway 69 and being rotatably mounted in the bearing 68, whereby, upon rotation of the screw the bearing 68 secured thereto may be moved relative to the guideway 69, and the pressure of the brush upon the surface of the web a varied to any desired extent.
As the web a passes from the brushes 65 and 66 it is engaged on its lower side by a felt roll 75. The roll 7 5 is mounted in a manner similar to the rolls 40 .47 in an adjustable bearing 76 provided with a bracket supporting a motor 77, by means of which the felt r0117 5 ma be rotated.
The bearing (.6 is provided with a second bracket 78 adapted to support a water pan 79 into which the lower side of the roll projects. As the roll 75 is rotated within the pan 79 a certain amount of water is carried by the roll 75, upward, against the lower surface of the web a for the purpose of moistening the web, in order that it may be more efficiently handled by the succeeding machinery to which it passes from the coating machine.
In order to control the amount of moisture carried by the roll 75 to the web a, I provide a scraper board or wood doctor 80 adjustably mounted on the pan 7 9 in such a manner that the pressure of the wood doctor 80 upon the surface of the roll 75 may be minutely controlled. For this purpose the wood doctor is provided with end bearings 81 adapted to receive a threaded end 82 of the shaft 83 having at its opposite end ahand wheel 84, by which said shaft may be rotated. The threaded end of the shaft is rotatably mounted in bearings 85, 85 formed on a. bracket 86 secured to the pan 79.
The roll 75 and pan 79 may be adjusted I claim:
