Z Claims. (Cl. 91-53) This invention relates to smoothing devices. In the application of coatings of all kinds upon paper, textiles and the like, various methods of coating have been used such as by coating rolls, brushes, etc. In order to obtain the correct depth of coating, even appearance without brush marks, streaking or ribbing, various auxiliary devices havevbeen required such as doctors, brushes or rolls and combinations thereof.
One of the objects of this invention is to provide a device that will give a smooth even coating of uniform appearance without ribbing, streaking or other marks. Another object of the invention is to provide uniform thickness of coating may be had.
Still another object of the invention isto provide a smoothing device the pressure of which may be varied with precision dependent upon the 2o desired result.
A still further object of the invention is to provide a smoothing device for double coated material whereby the depth of coating and the uniformity and smoothness of the surface will be sides.
A still further object of the invention is to provide smoothing rolls for double coated material whereby a single adjustment will adjust the smoothiig device for both sides to give identical 39 results.
A still further object of the invention is to provide smoothing devices of simplified and unique construction whereby better results can be obtained than have heretofore been possible.
85 Referring to the drawings:
Figure 1 is anend view of a device embodying the principles of my invention.
Figure 2 is a viewin side elevation of Figure 1.
Figure 3 is a detail view of the smoothing dei vices showing the adjustment screws for lining up the rolls in proper relationship.
Figure 4 is a diagrammatic view showing the smoothing devices in adjusted position for increased pressure and a modified form with a plurality of notches.
In carrying out my invention I propose to provide on frame 2 adjacent the coating rolls 25 or other coating means the smoothing device which consists of carriages 1 having blocks 3 supported Blocks 3 are adjustable with respect to carriages l by means of handwheels 20, 21, secured to rotatable threaded shafts 22, 23.
as shown in Figure 2 then if `they are adjusted through gears 6, 6', to exert added pressure they will automatically be in proper position as the 10G material is merely bent around the cylindrical surface adjacent the notches 12 and 13 as shown in Figure 4. The adjustment of the smoothing devices to change their effect is by means of worm 14 mounted on a bracket on carriage 3 which 105 meshes with gear 16 on shaft 24 journaled in frames 4. Gears 27, 27', are also secured to shaft 24 and mesh with gears 6, 6', to rotate the smoothing devices 10 and 11. Worm 14 is turned by pin 2,8 through shaft 15.
The operation of the device is as follows:
It will thus be seen that I have invented a smoothing device of simple construction the action of which is easily regulated and which in operation eiectively smooths and renders uniform the coating both as to appearance and depth.
What I claim is:
1. A smoothing device comprising a pair of cylindrical rolls in parallel spaced relationship, means for passing the coated material between said rolls, means for simultaneously rotating said rolls about an axis whereby said rolls each apply predetermined pressure equally on opposite sides of the paper.
2. A smoothing device comprising a pair of cylindrical rolls in parallel spaced relationship, means for passing the coated material between said rolls, the surface of each roll having a notch lengthwise thereof, means for rotating said rolls about an axis whereby said rolls each apply predetermined pressure and means for adjusting said rolls whereby the coated material leaves the cylindrical surface of each roll at the notch regardless of the applied pressure.
