Definitions
- This invention provides a roller device for applying liquid means, which is of simple and economical construction, requires that only a number ofcomponent parts be stocked by a printer, and has means for precisely locating its liquid-applying surface.
- FIG. 1 is a front view illustrating one exemplary embodiment of a roller device of this invention particularly adapted for applying liquid varnish to associated sheet means;
- FIG. 2 is a cross-sectional view taken on the line 2-2 of FIG. 1 and particularly illustrating a radially expandable member comprising the roller device of FIG. 1 made of a resilient rubberlike material and having sleeve means fastened in position concentrically therearound in the form of a plurality of three annular bands each having an outer liquid-applying surface;
- FIG. 3 is a greatly enlarged fragmentary cross-sectional view particularly illustrating the manner in which the radially expandable member is urged tightly against an associated annular band to hold such annular band in position;
- FIG. 4 is an exploded view with parts in section and parts in elevation particularly illustrating the roller device of FIG. 1 with its plurality of three annular bands arranged in position concentrically around the radially expandable member and prior to fastening a central core member of such roller device in position within the radially expandable member;
- FIG. 5 is a greatly enlarged fragmentary cross-sectional view particularly illustrating the construction of the substantially unstretchable annular band arranged at the right end of the roller device of FIG. 1;
- FIG. 6 is a view similar to FIG. 1 and particularly illustrating the radially expandable member of FIG. 1 and its associated core components utilized together with a pair of identical annular bands each having a length which is different from the lengths of the annular bands illustrated in FIG. 1 and with such pair of annular bands being positioned at different axial positions along the radially expandable member.
- FIG. 1 of the drawings illustrates an exemplary roller device of this invention which is designated generally by the reference numeral 20 and such roller device is particularly adapted for applying liquid means such as a varnish to sheet means of any suitable material such as paper, cardboard, metal, and the like over controlled areas such as over elongated strips of predetermined widths.
- the roller device 20 has certain basic component portions which are stocked as standard reuseable items; yet the roller device has simple and economical liquid-applying surface means capable of being used with the reuseable standard items to define a roller device ofoptimum versatility.
- the roller applicator device or roller device 20 comprises a radially expandable member 21 which has continuous annular sleeve means in the form of a plurality of three annular bands 22 having different axial lengths and each being supported concentrically around the expandable member 21.
- Each sleeve means or annular band 22 has an outer liquid-applying surface 23 which in this exemplary application is particularly adapted for applying liquid varnish, or the like.
- the roller device 20 has means for expanding and holding the expandable member 21 against inside surface means or inside friction surface 24 of each annular band 22 and such means is designated generally by the reference numeral 25 and will be referred to as expanding means 25.
- the expanding means 25 is of optimum simplicity and enables the expandable member 21 to be expanded radially outwardly so that its outer periphery may be arranged at any one of an infinite number of radial positions and as will be described in more detail subsequently.
- the radially expandable member 21 is in the form of an elongated substantially tubular member having an outer right circular cylindrical surface 26, a pair of oppositely arranged ends 27, and a tapered inside surface 30 which in this example of the invention has a substantially frustoconical configuration, see FIG. 4.
- the expandable member 21 is preferably made of a resilient rubberlike material and its outer cylindrical surface 26 has a given diameter 31 with the expandable member 21 in its unexpanded position.
- the expandable member 21 is expanded and held by the expanding means 25 to a diameter designated by the reference numeral 32 in FIG. 3 to thereby urge the cylindrical surface 26 against the inside surface 24 of each annular band and hold each annular band 22 firmly in position on the expandable member 21.
- the expanding means 25 may be easily released or unfastened, in a manner to be subsequently described, whereby the resilient character of the material utilized to make the expandable member 21 assures that such member is restored to its original configuration having the diameter indicated at 31.
- the expanding means 25 comprises tapered means having an outside surface corresponding in configuration to the frustoconical inside surface 30 of the expandable member 21 and the tapered means in this example of the invention is shown as a substantially rigid tapered core member 34.

SUMMARY This invention provides a roller device for applying liquid means, which is of simple and economical construction, requires that only a number ofcomponent parts be stocked by a printer, and has means for precisely locating its liquid-applying surface.
Other details, uses, and advantages of this invention will become apparent as the following description of the embodiments thereof presented in the accompanying drawings proceeds.

FIG. 5 is a greatly enlarged fragmentary cross-sectional view particularly illustrating the construction of the substantially unstretchable annular band arranged at the right end of the roller device of FIG. 1; and
FIG. 6 is a view similar to FIG. 1 and particularly illustrating the radially expandable member of FIG. 1 and its associated core components utilized together with a pair of identical annular bands each having a length which is different from the lengths of the annular bands illustrated in FIG. 1 and with such pair of annular bands being positioned at different axial positions along the radially expandable member.
DESCRIPTION OF ILLUSTRATED EMBODIMENTS Reference is now made to FIG. 1 of the drawings which illustrates an exemplary roller device of this invention which is designated generally by the reference numeral 20 and such roller device is particularly adapted for applying liquid means such as a varnish to sheet means of any suitable material such as paper, cardboard, metal, and the like over controlled areas such as over elongated strips of predetermined widths. The roller device 20 has certain basic component portions which are stocked as standard reuseable items; yet the roller device has simple and economical liquid-applying surface means capable of being used with the reuseable standard items to define a roller device ofoptimum versatility.
As seen particularly in FIGS. 2 and 4 the roller applicator device or roller device 20 comprises a radially expandable member 21 which has continuous annular sleeve means in the form of a plurality of three annular bands 22 having different axial lengths and each being supported concentrically around the expandable member 21. Each sleeve means or annular band 22 has an outer liquid-applying surface 23 which in this exemplary application is particularly adapted for applying liquid varnish, or the like.
The roller device 20 has means for expanding and holding the expandable member 21 against inside surface means or inside friction surface 24 of each annular band 22 and such means is designated generally by the reference numeral 25 and will be referred to as expanding means 25. The expanding means 25 is of optimum simplicity and enables the expandable member 21 to be expanded radially outwardly so that its outer periphery may be arranged at any one of an infinite number of radial positions and as will be described in more detail subsequently.
The radially expandable member 21 is in the form of an elongated substantially tubular member having an outer right circular cylindrical surface 26, a pair of oppositely arranged ends 27, and a tapered inside surface 30 which in this example of the invention has a substantially frustoconical configuration, see FIG. 4. The expandable member 21 is preferably made of a resilient rubberlike material and its outer cylindrical surface 26 has a given diameter 31 with the expandable member 21 in its unexpanded position. The expandable member 21 is expanded and held by the expanding means 25 to a diameter designated by the reference numeral 32 in FIG. 3 to thereby urge the cylindrical surface 26 against the inside surface 24 of each annular band and hold each annular band 22 firmly in position on the expandable member 21. The expanding means 25 may be easily released or unfastened, in a manner to be subsequently described, whereby the resilient character of the material utilized to make the expandable member 21 assures that such member is restored to its original configuration having the diameter indicated at 31.
The expanding means 25 comprises tapered means having an outside surface corresponding in configuration to the frustoconical inside surface 30 of the expandable member 21 and the tapered means in this example of the invention is shown as a substantially rigid tapered core member 34. The core member 34 has a frustoconical outside surface 35 which corresponds to and is adapted to be received within the frustoconical surface 30 of the radially expandable member 21 and the core member 34 is adapted to be moved from the position illustrated at 36 in FIG. 4 and slid axially within the radially expandable member 21 to serve the dual purpose of supporting the member 21 and radially expanding such member depending upon the amount that the core member 34 is axially slid within the expandable member 21. It will also be appreciated that once the core member 34 is fastened in position relative movement cannot take place between such core member and the expandable member 21.
The expanding means 25 also comprises thread means in the form of a threaded portion 40 provided adjacent the small diameter end of the frustoconical male or outside surface 35 of the core member 34 and comprises flange means in the form of an annular flange 41 which is adapted to engage an associated end 27 of the expandable member 21. The expanding means 25 also comprises a threaded nut 42 which has female threads provided therein which are adapted to be threaded over the threaded portion 40 so that upon inserting the core member 34 within the tubular expandable member 21 the frustoconical outside surface 35 engages the cooperating frustoconical surface 30 of the expandable member 21 and upon tightening the nut 42 over the threaded portion 40 with the annular flange 41 being urged against its associated end 27 of the expandable member 21 the net effect is to provide a central support for the expandable member 21 while simultaneously radially expanding the cylindrical outer surface 26 against the inside surface 24 of each annular band 22 and tightly hold each band in position.
During the process of manufacturing the expandable roller 21 and the annular bands 22 it will be appreciated that these parts will be made within established tolerance limits; however, the unique construction of the roller device of this invention enables the member 21 and the inside diameters of the annular bands 22 to be made to comparatively wide tolerance limits. Nevertheless, because the member 21 may be easily expanded to an infinite number of radial positions so that it may have any desired diameter of an infinite number of possible diameters all component parts of the roller device 20 are useable and may be made more economically in mass production quantities.
The core member 34 of the roller device 20 of this invention also has shaft means shown as a pair of oppositely arranged right circular cylindrical shaft portions 44 provided at opposite ends thereof. The shaft portions 44 are adapted to rotatably support the core member 34, expandable tubular member 21, and hence the entire roller device 20 with its annular bands 22 in a manner which is well known in the art. The shaft portions 44 of this example of the invention are shown as being made as an integral part of the core member 34.
The exemplary roller device 20 has a drive means in the form of a toothed drive gear 45 which is suitably fixed to the core member 34 adjacent an associated shaft portion 44. The gear 45 drives, i.e., rotates, the roller device 20 and may be engaged by an associated driving gear which meshes therewith in a known manner. The toothed gear 45 is merely presented as an example of a device which may be utilized to rotate the roller device 20; however, it is to be understood that any suitable known device may be utilized to rotate such roller device.
As previously indicated in the expandable member 21 is preferably made of a resilient material which may be in the form of a rubberlike material, or the like, and upon utilizing the expanding means 25 to expand the expandable member 21 radially outwardly the expansion causes annular portions of the right circular cylindrical outer surface 26 to frictionally engage the inside surfaces 24 of the annular bands 22 and frictionally hold such bands against axial movement. As the member 21 is expanded against the comparatively unstretchable bands 22 portions of member 21 adjoining opposite side edges 46 of each annular band 22 bulge outwardly and as shown at 47, see FIG. 3. The bulging of member 21 as shown at 47 assures that each annular band 22 is held more firmly in position and against axial movement relative to the expandable 21.
As mentioned earlier each annular band 22 is in the form of the substantially unstretchable band which is constructed so that its outer liquid-applying surface 23 is particularly adapted to apply a given liquid on an associated article, such as a sheet means, which is to be coated with liquid. Further, as seen particularly in FIG. 5 of the drawings, the inner portion of each band 22 is preferably made of an unstretchable material which may be reinforced with suitable cords 52 to prevent circumferential elongation.
The annular bands 22 may be made by conventional methods such as those used in the manufacture of drafting aprons and other textile sleeves and the cord members 52 may be spirally wound in a known manner so that each annular band 22 is sufficiently reinforced to assure circumferential elongation will not occur. The thickness, indicated at 53, of each annular band 22 is determined based on the intended use of each band 22 and such thickness generally takes into account the effective thickness of the resilient expandable member 21. In addition, the materials selected for the expandable member 21 and the annular bands 22 take into account the resiliency which is desired for the liquid-applying surfaces 23 of the annular bands 22.
The thickness 53 of each annular band 22 is generally the same as the depth of groove means that would ordinarily be provided in a similar roller applicator formed by conventional techniques. The outside diameter 31 of the radially expandable member 21 of this invention is also made so that it will be roughly the same as the original diameter of a conventionally formed roller applicator device minus twice the thickness of the annular band 22.
The exemplary roller device 20 is shown as having a plurality of three annular bands 22 of different axial lengths arranged concentrically therearound and each having a length which is substantially less than the length of the expandable member 21. However, it is to be understood that the length of each band, number of bands, and arrangement of such bands 22 axially along the elongated member 21 may be varied in any desired manner and depending upon the application of the roller device 20. lt will also be appreciated that a particular roller device may also be provided with a single annular band having an axial length which is equal to or substantially smaller than the length of the particular roller device.
The versatility of the roller device of this invention is highlighted in FIG. 6 of the drawings, which illustrates a roller device which is designated generally by the reference numeral 20M for convenience and represents a modification of the roller device 20 with only difference being that only a plurality of two equal width annular bands are provided concentrically around the roller device 20M. The remaining component portions of the roller device 20M have been given the identical reference numerals as in the roller device 20 and to highlight the difference in only the two annular bands such bands are each designated by the reference numeral 22M and each band 22M is provided with an outer liquid-applying surface 23M.
From the above description it will be apparent that the roller device 20 of this invention has optimum versatility and the method utilized in making such roller device assures provision of a roller applicator device which has a readily changeable liquid-applying outer surface. Thus it is only necessary for a printer to merely stock sleeve means or annular bands similar to the annular bands 22 and 22M and when it is desired to change the outer liquid-applying surface of a particular roller device for a given application it is merely necessary to loosen the nut 42 and move the core member 34 axially relative to the expandable member 21, causing the frustoconical surface 35 of the core member 34 to move away from the frustoconical inside surface 30 of the member 21 whereby the resilient character of the expandable member 21 causes the right circular cylindrical surface 26 to be restored to its original diameter 31 as illustrated in FIG. 4.
With cylindrical surface 26 restored to its original diameter, it is then a simple matter to position along the cylindrical outer surface 26 of the member 21 and again tighten the nut 42 whereby the new annular bands are held in position by friction and the bulging action as indicated at 47 in P16. 3. The positions of the annular bands 22 being used for a particular application may also be readily adjusted along the outer cylindrical surface 26 merely by loosening the nut 42 and then again tightening such nut with the annular bands at their new positions.
The core member 34 may be made of any suitable comparatively inexpensive material such as a hard plastic or a metallic material. Also, to further reduce costs, a printer may stock members 21 which can be expanded to comparatively larger diameters whereby such printer may also carry unstretchable bands of different diameters, within predetermined limits, whereby roller applicators of different outside diameters may be readily available to the printer by stocking a bare minimum of component parts.
As previously explained, the roller device of this invention may be made very inexpensively because its components can be made to looser tolerances without detriment to the overall performance of such device. To further minimize operating costs associated with the device of this invention marking means may be provided on the outer periphery of the right circular cylindrical surface 26 of the expandable member 21 to aid in the precise placement of the annular bands 22. The marking means may be in the form of circumferential lines and once a job has been started it would not be necessary to completely change the set up of the machine if it is desired to change the location at which a strip of liquid, such as varnish,
is being applied against an associated sheet; instead the bands would be precisely shifted with the aid of the marking means.
