11 Claims.

' My invention relates to an apparatus for and method of coating fabrics. It has particular reference to the application of a coating of paint to a web of surface covering material. Surface covering material, such as felt base, is commonly covered witha more or less uniform base coat of paintof asuitable color before the decorative design is printed thereon. The purpose of the base coat is two-fold. It serves to prevent the color of the surface covering material from showing through the decorative design and it furnishes a base upon which the design may be readily applied. The base coat is applied to the web of surface covering material 5 by means of a doctor blade, and covers the entire top surface area of the web-of surface covering material. The paint used to formthe decorative design is applied over the base coat by means'of conventional printing blocks. If desired, the decorative design may be applied over only predetermined portions of the base coat, so that the base coat itself constitutes part of the completed pattern appearing on the upper surface of the web of surface covering material.

tices has been the lack of uniformity in the application of the base coat to the web of surface covering material. Stiff doctor blades have proved to be unsatisfactory because the unevenness of the felt base being coated resulted in thick applications of paint over the low spots and thin applications over the high spots. In many cases the paint would be entirely scraped, oil? the high spots. Thin doctor blades are capable of following the contour of the material being coated, but have the disadvantage of lack of a thin doctor blade is used is the condition of,

the paint being applied to the surface covering material. If the pain uniform consistency, on of the lumps may force the doctor blade up as it passes and allow an excess of paint to flow under the doctor.

It is an object of my invention to provide simple and economical means of regulating the application of a coating of paint to a fabric. It is a The chief disadvantage in the prior art prachas lumps or is not of further object of my invention to provide means and will be economical and eflicient in use.

Other objects of my invention will become apparent upon reading the annexed specification taken in connection with the accompanying drawings, in which,

Figure 1 is a perspective view of my apparatus,

Figure 2 is a fragmentary perspective view of a modified form of my doctor blade inverted and enlarged to illustrate its structural details,

Figure 3 is a fragmentary perspective view of 5 another modified form of my doctor,

Figure 4 is an end view of Figure 3, and

Figure 5 is an end elevation of a driving mechanism forimparting rotation to the doctor roll of Figure l. 2

In the drawings, the reference numeral 2 indicates a web of fabric, such as felt base, used to form a surface covering. The web of surface covering material is fed over a belt conveyor 3 mounted on therolls 4 and 5. The conveyor 3 is formed of a thick rubber belt to provide a resilient base for the web 2. The roll {is provided with a shaft 6 which may be driven from any suitable motor (not shown). The shaft 6 is rotatably supported by the uprights I secured to 30 the base 8 of the machine.- The uprights I are provided with bearings 9 through which the shaft 6 extends. The roll 5 is provided with a shaft l0 mounted in bearings H in supporting members l2. The shafts 6 and H] are provided 35 with sprockets l3 and I connected by a chain IS, the sprockets and the chain being shown in dotted lines, so that both rolls 4 and 5 are driven 1 at the same speed.

The uprights l are cut out as indicated at I6 40 to receive a pair of blocks l1 and I8 adapted to support a primary doctor IS. The doctor shown in Figure 1 is in the form of a roll, the surface of which is provided with'a helical groove 20; If desired, a plurality of concentric circular 45 grooves may be shubstituted for the helical groove 20. The doctor roll I! is provided with a shaft 2| which is supported in bearings 22 secured in the blocks l1 and I8. One end of the shaft 7| is squared, asindicatd at 23, to adapt 50 it to receive a wrench. A ratchet 24 is secured to one end of the shaft 2! outside the block Ill. The block I8 is provided with a pawl 25 adapted to prevent undesirable rotation of the doctor roll IS. The blocks I1 and" are adjustably secured- 55 in the uprights T by means of the screw threaded bolts 26. The bolts 26 are provided with square heads so that they may be engaged by a wrench. A hand wheel may be secured to the top of the screw threaded bolts 26 if desired.

Guide plates 21 are secured to the uprights 1 by means of brackets 28. The guide plates 21 conform to the contour of the roll 4 and serve to retain a bank of paint 29 on the web of surface covering material so that it does not spread past the edges of the web. The 'roll 4 is mounted slightly higher than the roll 5 so that a pocket is formed in front of the doctor l9. The pocket is sufficiently large to maintain the bank of paint in front of the doctor.

The supporting members |2 have a pair of brackets 30 secured on their upper edge. The brackets 30 support a cross bar 3| to which a secondary doctor 32 is secured. The secondary doctor consists of a thin, flexible metal blade arranged at an angle to the web of surface covering material in flexed position with its exposed edge facing in the direction of travel of the web of surface covering material so that it spreads out the paint to form a coating of uniform thickness on the web as shown in Figure 1.

The operation of my coating apparatus is as follows: The paint to be applied to the web of surface covering material is placed directly in front of the primary doctor l9 and is confined by the guide plates 21 within limits defined by the edges of the web of surface covering material. As the web of material is fed under the primary doctor by the conveyor 3 a predetermined amount of paint is fed therewith through the grooves in the surface of the doctor roll. The primary doctor l9 does not spread the paint over the web of surface covering material. Its only function is to regulate the amount of paint to be applied to the surface covering material.

The amount of paint applied to the web may be regulated by adjustment of the vertical position of the blocks l1 and |8 in which the shaft 2| of the doctor I9 is mounted. When any surface of the doctor roll I9 becomes worn the do tor may be rotated so as to present a new surface to the web of surface covering material. If desired, I may provide means connected to the motor for imparting a continuous rotary motion to the doctor. A suitable driving means for imparting rotation to the doctor roll I9 is shown in Figure 5 and comprises a sprocket 5|) secured to shaft 6 and a similar sprocket 5| secured to shaft 2| upon which the doctor roll I9 is mounted. Sprockets 50 and 5| are connected by a chain 52 and motion is imparted to the roll l9 upon rotation of the shaft 6. Such rotation will prevent uneven wear on the surface of the doctor. The rate of rotation of the doctor will be relatively slow so as not to affect the distribution of the'paint over the web of surface covering material.

The bank of paint lying in front of the doctor l9 wets the entire upper surface of the web of surface covering material. The doctor roll l9 fits so closely against the web of surface covering material passing over the conveyor belt 3 that no paint can pass between the doctor roll and the web of surface covering material except that which passes through the grooves 20. The ridges of the doctor roll scrape the paint off the portions of the surface covering material not directly under the grooves. This causes the formation of-a plurality of continuous paint ridges 33 of uniform cross sectional area spaced equi-distantly across the width of the web of surface covering material. The cross sectional areas of the ridges of paint are equivalent to the cross sectional area of the corresponding grooves in the primary doctor. The primary doctor insures a uniform quantity of paint, and uniform distribution of the paint in front of the secondary doctor, so that the only requirement of the secondary doctor is that it smoothes the paint which passes thereunder.

The secondary doctor 32 engages the paint ridges 33 and smooths them so as to form a smooth uniform base coat covering the entire upper surface of the web of surface covering material. This smoothing action is accomplished easily because even those areas of the surface covering material which lie between the ridges of paint have been previously wetted by the paint in front of the primary doctor. The primary doctor allows the paint to pass only through its grooves, but the portions of the web of surface covering material from which the paint is removed by the'primary doctor retain the moisture imparted thereto by the paint. The presence of this small amount of moisture in the surface covering material facilitates the adherence of the paint to the entire upper surface of the web of surface covering material when the paint is spread and smoothed by the secondary doctor. The web of surface covering material is then capable of receiving any suitable decorative coating.

In Figure 2 I have-shown a rigid doctor blade 34 in the form of a flat bar which may be substituted for my primary doctor IS. The doctor 34 contains a plurality of slots 35 so that it may be secured to a suitable cross bar. The slots are preferably elongated so that the position of the doctor blade may be adjusted with reference to the cross bar to which it is secured. The cross bar would be mounted in a pair of blocks similar to the blocks l1 and l8. The bottom surface of the doctor 34 is provided with a plurality of grooves 36.

In Figures 3 and 4 I have shown another modification of my doctor. In this case the grooves 31 for the passage of the paint are formed by adjacent convolutions of a wire 38 wrapped around the roll 39. The end of the wire 38 is secured to the roll'39 by having its ends bent into suitable openings 40.
