My invention relates to coating machines and process of coating cylindrical objects such as wrapped cans with coating material such as varnish. p
It is the object of my invention to provide coating rolls adapted to'carry a layer of the coating material, which rolls are so constructed and mounted, and which rolls are operated at such a speed that cylindrical objects having depressed portions and annular grooves in their outer peripheries-will be coated with a smooth layer of the c0ating material.
In wrapping food stuffs and many other classes of material which are affected by moistureor air, it has long been known that cans which are wrapped with wet wrappers, which are afterward shrunk on by heat will have more thoroughly sealed joints than cans which are wrap with a plain unmoistened wrapper. It proposed to varnish the labels of wrappers and then shrink them onto can bodies, but this has not been practical as the varnishing prior to applying to the can bodies prevents the proper shrinkage of, the wrappers, and mars the appearance of the wrapped cans.
By the use of my novel process and by the use of machines incorporating the mechanical principle involve in the ensuing description, cans may be wrapped with moist wrappers. The wrappers can then be shrunk onto the cans by heat and as a final step a coating of varnish may be applied which will make a doubly leakproof package, and the varnish will be evenly distributed in any annular grooves or channels.
Referring to the drawings in which I have shown diagrammatically a suitable machine far carrying out my process:
Figure 1 is a diagrammatic section.
Figure 2 is a diagrammatic side elevation showing a simple type of drive for the varnishing rolls.
Generally indicated at 1 is the varnish pan. which may be mounted for vertical adjustment on a screw actuated bracket 2 extended through the frame 3 of the machine. A roller 4 which. may be called the feed roll, extends within the tank and thus carries on its outer periphery a coating of varnish such as is indicated at 5. The feed roller 4 may be rotatably mounted in the frame 3 of the machine and" although the roller must, of course, be rotated to feed varnish, in my preferred type of machine as further been" no independent drive for the .roller 4 is provided, a drive which may be controlled to rotate the feed roll at a predetermined rate i will not be objectionable.
There are two rollers hagng shafts 6 and 7and bodies '8 and 9 respectively, composed of rubber or other suitable varnish distributing materialf distributing In the diagram I have shown the shaft and roller 7 and 9 on the ri ht with respect to a line drawn upwardly mm the feed roller.
The shafts are preferably demountably mounted in the frame of the machine as by means of hingedbearing bocks 8 and 9?,- which allow the resilient rollers to be lifted out of their bearings and cleaned ofl' so as not to allow a coating of the varnish to surface of the rollers.
Fordriving the rollers and the feed roller .dry and harden on the smooth resilient outer I have shown the sprocket wheels 10 and 1 1 driven by'a chain12 which is driven by a pinion 13. The pinion is mounted on a shaft 14 which carries a large gear 15 which meshes with a gear 16 whichis mounted on the shaft of, a motor 17 which drives the machine. The small sprocket 10 which drives the roller 8 is preferably adapted to rotate. the roller 8 at about twice the speed of the roller 9 which is driven by the larger sprocket 7. The roler 9 bears against the feed :roller 4- and thus causes it to rotate within the varni sh tank. The roller 8 which rotates at the fastest rate bears. gently against the feed roller so that a light film of varnish will be distributed over its outer periphery. v
It will be noted that the two rubber rollers do ndttouch each other and the distance apart will be such that a cylindrical object will. fit between the rollers in the manner indicated by the can shown in dotted lines at 18. The speed of rotation of the can will then be governed by the speedof that .roller which is rotated at the fastest speed and the varnish. will thus be built up on the roller moving at the slower speed so that the layer of varnish which becomes coated on the can will be thoroughly pressed into any uneven annular channels or indentations which arepresent on the article to be coated.
While I have shown a simple form of of a ro ler against which the machine, it will be apparent that many modifications which will eliminate the necesslty for hand feeding of each article to be coated will readily occur to those skilled in the art. The method which I claim in combination with the machine of which I have shown diabe moved by gravity toward a line betweenthe rollers, it will be obvious that other posi tions of angular adjustment may be arranged which will not affect the principle involved.
Having thus described my invention, what 1 claim as new and desire to secure by Letters Patent, is
1. That process of coatingcylindrical ob.- jects which consists in rotating the ob ec ts by peripheral contact with a relatively rapid moving roller, and applyln a coating of material to the cylindrical obiects by peripheral contact with a relative y more slowly rotating roller.
2. That process of coatingcylmdrical objects which consists in rotat1ng the ob ects 3y peripheral contact with a relat vely rapidly rotating roller and distributing by peripheral contact with a relatlvely more slowly rotating roll, a layer of the coating on the cylindrical objects and supplying the coating on the relatively slow movingroller by surface engagement with a feed roller inserted in a source of supply.
3. In a machine for coating cylindrical objects, a lurality of coating rollers, a source of supp y for coatin rotating one of said ro lers at a certain speed, and means for rotating another at a lesser material, means for speed, means for a plying a relatively thick coating to that ro ler which rotates at the slowest speed and means for applying a relatively lighter coating to the roller moving at the fastest speed.
4. In a machinefor coating cylindrical objects, a plurality of coating rollers, a source of supply for coating material, means for rotating one of said rollers at a certain s eed, and means for rotating another at a esser speed, means for applying a relatively thick coating to that roller which rotates at the slowest speed and means for applying a relatively lighter coatin to the roller moving at the fastest spee said coating roller mounted in interspaced position so as to pro vide an mterspaced area between said rollers of sufficient size to provide retainment for a segmental portion of a cylindrical object to be coated. 4
5. In a machine for coating cylindrical objects, a lurality of coating rollers, a source of supp y for coating material, means for rotating one of said rollers at a certain speed, and means for rotatin another at a lesser speed, means for applyin a relatively thick coating to that roller which rotates at the slowest speed and means for applying a relativel lighter coating to the roller moving at the astest speed, said coating rollers having resilient outer peripheries.
6. In a machine for coating cylindrical obtively lighter coating to the roller moving atthe fastest speed, said coating rollers having resilient outer peripheries, and a feeding roller for coating driven by peripheral contact with the relatively slowly moving coating roller. ROBERT F. BECHT.
