Patented June 14, 1949 COATING MACHINE FOR FLEXIBLE SHEET MATERIALS Joseph Ettl, Brooklyn, N. Y., assignor to Rogers Industries, Inc., New York, N. Y., a corporation- Application July 3, 1946, Serial No..681 ,376
6 Claims. (01. 91-50) This invention relates to a gluing or strip coating machine and an object of this invention is to provide a machine which will efficiently apply an adhesive to vellum, cardboard, sheets of paper, etc.
an excess deposit of glue on the opposite side of the material being coated. This excess glue spoiled the material and necessitated the entire stoppage of the machine to clean the feed rollers.
In the mechanism herewith disclosed, only a single adjustment is required. This single adjustment provides a safety feature, the prevention of depositing excess adhesive onto the feed rollers. The coating roller is made to move from both the supply roller and the feed rollers simultaneously when an increased or decreased amount of adhesive is required on the coating roller.
Furthermore, in practice it has been proven that the amount of adhesive deposited on the coating roller depends upon the distance between the supply roller and the coating roller, andthat when the amount of adhesive on the coating roller is increased, that the surface of the coating deposited upon the coating roller increases in roughness of the surface of the adhesive.
In other words, heavy ridges are formed in the coating surface, depending upon the consistency of the adhesive, the said ridges being higher than the normal adjustment of the coating would ordinarily indicate.
In order tocompensate for this unevenness of the coating surface, I have positioned the axis of the supply roller at a sixty degree angle below the horizontal line passing through the axis of the coating roller and I have positioned the median line between the feed rollers at a thirty degree angle above the said horizonta1 line.
This arrangement of the roller positions causes a greater opening to be formed between the feed rollers and the coating roller than thempening between the coating roller and the supply roller for an equal amount of horizontal movement of the coating roller to or from the set position of th supply roller.
With the above and other objects in view, the invention will be hereinafter more particularly described, and the combination and arrangement of parts will be shown in the accompanying drawings and pointed out in the claims which form part of this specification.
Reference will now be had to the drawings, wherein like numerals of reference designate corresponding parts throughout the several views, in which:
Figure 1 is a side elevation of my improved coating machine.
Figure 2 is a cross-sectional view, the section being taken as on line 2--2 in Figure 1.
Figure 3 is an enlarged assembly view of a fragmentary portion of the machine showing a preferred arrangement of the relative positions of the coating roller, supply roller, feed rollers and coating adjustment means. a
. In the illustrated embodiment of the invention, the numeral l0 indicates a gluing or coating machine comprising a receptacle ll having upright side walls l2.
Rotatably mounted in the walls l2 in sealed bearings I3 is an adhesive pick-up roller .or supply roller I 4. The sealed construction of the bearings I3 makes it possible to mount the bearings below the level of the adhesive and fully immersed in the adhesive, and to mount the supply roller M with about four-fifths of its diameter immersed in the adhesive.
The side walls l2 also provide bearings fora,
coating roller l5 carried by a shaft IS. The shaft I6 is rotatably mounted in rectangular guide blocks I! which are slidably mounted in guideways l8. Theguideways extend through the side walls l2 so as to form openings for the shaft l6.
Each side wall l2 also provides a rectangular guideway 20 which is in angular relation with each of the guideways l8. A bar 2| is secured to the wall l2 by screws 22 and covers each guideway 20.
A carrier 23 is slidably mounted in each guideway 20 and provides bearings for material feed rollers 25. Fixed in the carrier 23 by a pin 26 is a threaded member 21 which passes outwardly through an aperture in the bar 2 I. A coil spring 28 is mounted on-the threaded member 21 intermediate the carrier 23 and the bar 2| and urges the feed rollers in direction of the coating roller l5.
A threaded nut 29 on the member 21. serves for moving the feed rollers in a direction away from the coating roller. After adjusting the feed rollers 25 they remain set during operation of the in the direction of the supply roller i4 and the feed rollers 25.
Rotatably mounted in the side walls I! is an adjustment rod 31 having a threaded end portion 38.
An adjusting dial 39 is secured to the rod 3'! by a pin 40. The dial 38 is calibrated as shown at H.
- A pointer 42 is secured to a side wall I2 of the receptacle ii and extends in overlapping relation with the dial 38 and indicates the set position of the dial. A nut 43 threaded on the end portion 38 serves to lock the dial 39 in set position. It is to be noted that the hub of the dial has a slot M through which the pin 40 passes outwardly. The slot 44 extends through the hub and provides clearance space for movement of the pin therein. As best shown in Fig. 3, the adjustment rod 31 has cam means 45 formed near each end of the rod by eccentrically turning out portions thereof in alinement with the walls I2. Cam blocks 46 are slidably mounted in an extension 30' of the aperture 30. 'The cam blocks 46 are in alineme t with the cam means 45. Adjusting screws are threaded in the cam blocks 45 at one end and-in engagement with the slidable blocks II at the opposite end.
Each screw 41 has apertures 48 in which an elongated pin may be inserted for adjusting the screw with relation to a cam block 46. It will thus be seen that the springs urge the bearing blocks I! and the coating roller i5 in directionof the supply roller 14 and the feed rollers 25, whereby a single adjustment of the coating roller 15 causes movement of the coating roller l5 to or from both the supply roller i4 and the feed rollers 25 simultaneously. I
I provide a heating chamber 50 for oil below the supply roller H for heating the supply roller. For the purpose of effectively circulating the oil in the heating chamber 50, I provide a shaft 5| having right-hand and left-hand rotors 52. The
pinion gear which meshes with a gear 56 driven by a, motor (not shown). The gear is secured to the supply roller shaft 51. Secured to the shaft i6 is a gear 58 which meshes with pinion gears I8 secured to reduced end portions of the feed rollers 25. Rotation of the ear 56 causes rotation of all the gears and the rollers actuated thereby.
It is to be noted that the axes of the supply roller i4 and the feeding rollers 25 are positioned on the same side of a vertical plane passing through the axis of the coating roller l5.
In accordance with the patent statutes, I have described and illustrated the preferred embodiment of my invention, but it will be understood that various changes and modifications can be made therein without departing from the spirit of the invention 'as defined by the appended claims.
