Definitions
- This invention relates to an improved poly- meric product having a fabric layer means, and to a method of making such a polymeric product.
- a woven fabric structure that has been impregnated or coated with a polymeric means, such as a latex, has been used as an encapsulating or reinforcing member in endless transmission belts, such as a V-belt, and in other products, and has undergone a progression of change, principally directed toward the relationship of the warp fill angularity to the longitudinal axis of the belt.
- the warp or fill of the fabric was at right angles to the longitudinal axis; then the fabric was subsequently cut and turned on a 90° bias; then the fabric was subsequently cut and turned to a 120° bias; and then today the fabric comprises a seamless bias disposed at 120°.
- Each such change in the polymeric coated fabric was primarily directed toward improving product flexibility. However, it was found according to the teachings of this invention that during such changes the three-dimensional aspect of the plain weave of the fabric had not been altered. It is also well known in the art that improving structural flexibility or bending modulus of the polymeric coated fabric can be altered by decreasing yarn density (cover factor), decreasing twist of the yarn system, increasing the warp/fill angle, and/ or decreasing the number of cross-over points in the woven structure.
- a fabric means can be provided wherein the bias orientation is maintained while the third dimension function is eliminated. This is accomplished by utilizing polymeric means as the effective sole securement means between the threads of the fabric means so as to impart its flexibility characteristic to the securement means of the fabric means, whereby the resulting product has the desired structural flexibility or bending modulus.
- one embodiment of this invention provides a polymeric product having a fabric layer means provided with opposed sides, and at least one polymeric means secured to the fabric layer means.
- the fabric layer means comprises a first substantially planar layer of thread means disposed in superimposed relation with a second substantially planar layer of thread means, whereby the thread means of the first layer are not woven with the thread means of the second layer, the polymeric means effectively being the sole securement means securing the thread means of the first layer to the thread means of the second layer, and thereby imparting its flexible characteristic to the securement means between the thread means of the first and second layers.
- Another object of this invention is to provide an improved method of making such a product, the method of this invention having one or more of the novel features of this invention as set forth above or hereinafter shown or described.
- FIG. 1 is an enlarged, fragmentary, partially broken away, cross-sectional, schematic, perspective view of an improved polymeric product of this invention
- FIG. 2 is a cross-sectional view of an endless transmission belt construction utilizing the polymeric product of FIG. 1;
- FIG. 3 is a fragmentary view similar to FIG.
- FIG. 4 is a fragmentary perspective view illustrating another product of this invention utilizing the polymeric product of FIG. 1;
- FIG. 5 is a schematic top view of an improved method and apparatus of this invention for making the polymeric product of FIG. 1;
- FIG. 6 is an enlarged schematic side view of the method and apparatus of FIG. 5;
- FIG. 7 is a schematic view illustrating a certain portion of the method and apparatus of FIGS. 5 and 6;
- FIG. 8 is an enlarged, schematic, fragmentary cross-sectional view taken on line 8-8 of FIG. 7;
- FIG. 9 is a view similar to FIG. 8 and illustrates another embodiment of this invention.
- FIG. 10 is a view similar to FIG. 8 and illustrates another embodiment of this invention. Best Modes for Carrying Out the Invention

- the fabric layer means 21 of this invention comprises a first substantially planar layer 26 of thread means 27 disposed in superimposed relation with a second substantially planar layer 28 of thread means 29, whereby the thread means 27 of the first layer 26 are not woven with the thread means 29 of the second layer 28, but are secured thereto by the polymeric means 24, 25 in such a manner that the polymeric means 24, 25 effectively comprises the sole securement means securing the thread means 27 of the first layer 26 to the thread means 29 of the second layer 28, and thereby imparts its flexible characteristic to the securement means between the thread means 27 and 29 of the first and second layers 26 and 28.
- the resulting polymeric-coated fabric layer means or polymeric product 20 of this invention will have an improved structural flexibility or bending modulus than if the fabric layer means 21 had comprised a conventional woven fabric layer means, such as set forth in the aforementioned U.S. Patent Nos. 4,062,989 and 4,238,530, or had comprised stitched or needled structure as set forth in the aforementioned U.S. Patent No. 3,998,986, whereby these three U.S. Patents are being incorporated into this disclosure by this reference thereto.
- the polymeric-coated layer means 20 of this invention can be readily utilized by itself, or with another polymeric product, by having one of the opposed outer surfaces 30 or 31 thereof secured to a surface of the polymeric product for the same purpose and in a manner similar to other prior known polymeric-coated fabric layer means.
- the copending U.S. Patent application of Delmar D. Long one of the co-inventors of this invention, Serial No. 350,969, filed February 22, 1982, wherein an additional tacky layer is provided on the polymeric-coated fabric layer means for such securement purposes.
- this copending U.S. patent application describes the various uses of polymericcoated fabric layer means, and a method and apparatus for making the same, which is similar to this invention, as will be apparent hereinafter, this copending U.S. patent application is being incorporated into this disclosure by this reference thereto.
- the polymeric product 32 comprises an endless power transmission belt of a typical "V" type, wherein a polymeric body 33 thereof has a substantially trapezoidal crosssectional configuration defined by a pair of opposed flat parallel top and bottom surfaces 34 and 35, with a pair of angled side surfaces 36 and 37 disposed therebetween.
- the belt construction 32 has the conventional tension section 38, compression section 39, and load carrying section 40 disposed intermediate the tension section 38 and the compression section 39 in a manner well known in the art, the sections 38, 39, and 40 being made mainly of polymeric material.
- the opposed angular surfaces 36 and 37 of the belt body 33 are each adapted to have a friction layer, which comprises a fabric that is impregnated with a polymeric composition, and which is secured thereon by such friction layer either being disposed only on the surfaces 36 and 37 thereof, or by having the entire outside surface of the belt body 33 wrapped with the friction layer.
- a friction layer which comprises a fabric that is impregnated with a polymeric composition, and which is secured thereon by such friction layer either being disposed only on the surfaces 36 and 37 thereof, or by having the entire outside surface of the belt body 33 wrapped with the friction layer.
- the belt construction 32 illustrated in FIG. 2 has the belt body 33 thereof completely wrapped by a strip of a polymeric-coated fabric layer means 20 of this invention, so that the opposed ends 40 and 41 of the layer means 20 are disposed and secured in overlapping relation, such as on the top surface 34 of the belt body 33 as illustrated in FIG. 2; this is conventional in the belt making art.
- the layer means 20 of this invention for forming the belt construction 32 of FIG. 2
- either the side 30 or the side 31 thereof can be disposed in contact with the outer surfaces 34, 35, 36, and 37 of the polymeric body 33, and it is believed that the improved flexible characteristic of the polymeric product 20 will permit the polymeric product 20 to more readily conform to such surfaces 34, 35, 36, and 37, so that during a subsequent heat curing or vulcanizing of the belt construction 32, after the layer means 20 has been wrapped on the belt body 33 in a manner well known in the art of making belt constructions, the polymeric product 20 will be secured to the belt body 33 throughout its entire outer surface area.
- the outer surface 30 or 31 of the layer means 20 of this invention provides the contact facing of the belt construction 32 at the driving or driven insides 36 and 37 thereof, as is conventional in the art, while the fabric layer means 21 provides the desired reinforcing characteristic to the belt construction 32 and at the same time provides an improved flexibility thereto because of the effective flexible securement between the thread means 27 and 29 of the first and second layers 26 and 28.
- the polymeric-coated fabric layer means 20 of this invention has been previously described as forming an outside surface of a belt product, it is to be understood that the layer means 20 of this invention can provide not only an outside surface thereof, but also in addition thereto, or in lieu thereof, can form part of an inner layer of the belt product if desired.
- FIG. 3 wherein another polymeric belt body or product 42 of this invention is provided, and comprises a pair of polymeric layers 43 and 44 respectively having facing sides 45 and 46 being secured to each other by a strip 47 of the layer means 20 of this invention that is disposed intermediate the polymeric layers 43 and 44 and is secured thereto during a subsequent heating, curing, or vulcanizing of the belt body 43 in a manner well known in the art of making belt constructions.
- the layer means 20 of this invention can provide a hose construction (generally indicated by the reference numeral 48 in FIG. 4) by having an elongated strip 49 of the layer means 20 of this invention helically wrapped and secured in overlapping relation in a manner well known in the hose construction art to provide the hose construction 48, together with or without additional wire reinforcing means as desired.
- the polymeric-coated fabric layer means 20 of this invention can provide part of a printing blanket, gasket means, etc., whereby it can be seen that the layer means 20 of this invention can be utilized as a product itself, or with other products not disclosed in this application, because it is believed that the same is readily adapted to be utilized where any such polymeric-coated fabric layer means is presently being used, or where such a polymeric-coated fabric layer means could possibly be used..
- the first layer 26 of thread means 27 of the polymeric-coated fabric layer means 20 comprises a plurality of threads, strands, yarns or the like disposed generally parallel to each other, with any desired pattern of spaces or non-spaces therebetween, and being disposed at an angle relative to the longitudinal axis of the layer means 20, such as being at an acute angle to the longitudinal axis 50 as illustrated in FIG. 1.

- any desired angle between the thread means 27 and 29 of the layers 26 and 28 can be provided, as desired.
- the thread means 27 and 29 of the layer means 26 and 28 could comprise any one suitable material, or could be blends of suitable materials, with the thread means 27 and 29 being uniform, dissimilar, or any desired combination thereof as desired.
- the polymeric means 24, 25 can comprise any suitable polymeric material, such as a latex, with the material of the layers 24 and 25 being like, similar or different, as desired.
- the polymeric means 24, 25 provides the sole securement between the thread means 27 and 29 of the layers 26 and 28 so as to add its flexible characteristic to such securement means, so that the layer means 20 will readily conform to the particular shape in the final product thereof, whether the same is formed into the hose 48 of FIG. 4, the belt configurations of FIGS. 2 or 3, or other products as desired, as well as add its flexibility to the final product together with the reinforcing characteristic of the fabric means 21 thereof. While it is believed that the polymeric-coated fabric layer means 20 of this invention can be made by any suitable method and apparatus, one such method and apparatus is generally indicated by the reference numeral 51 in FIGS. 5, 6 and 7, and will now be described.
- the method and apparatus 51 includes a tenter frame 52, similar to the tenter frames of the aforementioned U.S. patents and application, that is adapted to be moved in any suitable manner from left to right in FIGS. 5 and 6, and to have the two layers 26 and 28 of thread means 27 and 29 laid thereon at the desired angle so as to be disposed in the stacked relation illustrated in FIG. 1.
- the thread means 29 for the layer means 28 can be fed in beam fashion from a supply 53 thereof into an area 54 wherein the same are cut and laid across the tenter frame 52 from one side 55 thereof to the other side 56 thereof, and are held thereon by the conventional tenter pins 57, so that each thread means 29 extends from one side 55 of the tenter frame 52 to the other side 56 thereof at the desired angle relative to the longitudinal axis 58 of the tenter frame 52.
- another beam of the thread means 27 can be fed from a supply 59 thereof into the area 54 so as to have the thread means 27 thereof cut and laid across the tenter frame 52 on top of the thread means 29 at an angle relative thereto, so that each thread means 27 extends from the side 55 of the tenter frame 52 to the side 56 thereof at the desired angle relative to the longitudinal axis 58 of the tenter frame 52.
- the thread means 27 and 29 can be cut and laid on the tenter frame 52 in either a continuous or intermittent manner, as the superimposed layers 26 and 28 can then be indexed in a continuous or intermittent manner from left to right through the remaining portion of the apparatus 51 to have the polymeric means 24 and 25 applied thereto in much the same manner as provided by the methods and apparatus set forth in the aforementioned U.S. patents and copending U.S. patent application.
- the tenter frame 52 can be slightly outwardly stretched in the area of the reference numeral 60 in FIGS. 5 and 6 to make sure that the thread 27 and 29 are disposed in a taut relation as the same pass between suitable coating means 61 and 62 that are respectively disposed on opposite sides of the tenter frame 52 to respectively apply the polymeric coatings 24 and 25 in a liquid manner to the respective sides 22 and 23 of the fabric layer means 21, so that the coatings 24 and 25 will not only be secured to those sides 22 and 23, but also so that the coatings 24 and 25 will exude into the fabric layer means 21 to secure the thread means 27 and 29 thereof together when the coatings 24 and 25 are subsequently dried by the drying apparatus (generally indicated by the reference numeral 63 in FIGS. 5 and 6).

- the heating means 63 can comprise any suitable structure, the same comprises a heated air, oven-like member through which the layer means 20 passes from left to right, so that by the time the layer means 20 exits the heating means 63, the coatings 24 and 25 have been sufficiently dried so that the same will hold the thread means 27 and 29 in their assembled and encapsulated manner.
- suitable cooling means 67 can be provided to cool the layer means 20 before the same is wound into a supply roll 68 thereof.
- the supply roll 68 has a web 69 of material wound with the layer means 20 intermediate the coils thereof so as to prevent sticking of the coils of the layer means 20 in the supply roll 69 thereof if desired, as is well known in the art.
- coating means 70 and 71 can be respective ⁇ ly provided for the thread means 27 and 29 to apply a polymeric coating 72 to only the sides 73 and 74 of the thread means 27 and 29 which will be disposed facing each other in the manner illustrated in FIG. 9, so that the polymeric means 72 will provide sufficient adhesive means to hold the thread means 27 and 29 together as the same pass through the coating means 61 and 62 in the apparatus 51.
- the coatings 24 and 25, together with the coating 72 form the polymeric means that secures the thread means 27 and 29 together in the final product thereof.
- the layer means or polymeric product 20 of this invention could have a cross-sectional configuration that looks like the structure illustrated in FIG. 9 without having the additional coatings 24 and 25 applied therto, as the polymeric means 72 will still provide the effective sole securement means for securing the layers 26 and 28 of thread means 27 and 29 together.
- the polymeric applying means 70 and 71 can be so constructed and arranged that the same will completely coat the thread means 27 and 29 with a polymeric material 75 as illustrated in FIG. 10, so that when the thread means 27 and 29 are disposed in superimposed relation on the tenter frame 52, the resulting structure will have the appearance as illustrated in FIG.
- the coatings 24 and 25 can be subsequently applied thereto by the coating means 61 and 62 if desired.
- the coatings 24 and 25, together with the coatings 75 form the polymeric means that secures the thread means 27 and 29 together in the final product thereof.
- the coatings 24 and 25 need not be provided for forming the layer means or polymeric product 20 of this invention, as the polymeric material 75 will provide the only polymeric material thereof and will provide the effective sole securement means for securing the thread means 27 and 29 together in the manner previously set forth, and as illustrated in FIG. 10.
- the polymeric-coated fabric layer means or polymeric product 20 of this invention that comprises a fabric layer means 21, provided with opposed sides 22 and 23, and at least one polymeric means 72, 75, 24 and/or 25 secured to the fabric layer means 21;

Abstract
La couche de tissu (21) possède des côtés opposés (22, 23) et au moins une partie polymère (24, 25, 72, 75) fixée à la couche de tissu. La couche de tissu (21) comprend une première couche sensiblement plane (26) de fils (27) disposés de manière superposée par rapport à une seconde couche sensiblement plane (28) de fils (29), de sorte que les fils (27) de la première couche (26) ne sont pas tissés avec les fils (29) de la seconde couche (28). La partie polymère (24, 25, 72, 75) est le seul moyen de fixation effectif qui rattache les fils (27) de la première couche (26) aux fils (29) de la seconde couche (28), et confère ainsi sa flexibilité à la fixation entre les fils de la première et de la deuxième couches.The fabric layer (21) has opposite sides (22, 23) and at least one polymer part (24, 25, 72, 75) attached to the fabric layer. The fabric layer (21) comprises a first substantially planar layer (26) of threads (27) arranged superimposed with respect to a second substantially planar layer (28) of threads (29), so that the threads (27) of the first layer (26) are not woven with the threads (29) of the second layer (28). The polymer part (24, 25, 72, 75) is the only effective fixing means which connects the wires (27) of the first layer (26) to the wires (29) of the second layer (28), and thus confers its flexibility in fixing between the wires of the first and second layers.
