MACHINE FOR COATING.
Specification of Letters Patent.
Patented Mar. 28, 1916.
Application filed December 17, 1914. Serial No. 877,642.
provement in Machines for Coating, and do hereby declare that the following is a full, clear, and exact description thereof.
My invention relates particularly to an improvement in apparatus for producing coated fabricsbut, more especially, woven fabrics carrying acoating or layer of a ings, in which the figure is a diagrammatic nitrocellulose composition.
The object of my invention is to provide an apparatus capable of producing a product of this kind in which the layer of composition carried by the fabric will be very effectively and securely anchored on the fabric, and in which the coating composition will adhere in an effective manner to the fabric.
More especially the object of my invention is to produce goods of the quality stated without the useof a special cementing coat and to provide the total thickness of the coating in one operation.
While my invention is capable of embodi ment in many different forms, for the purpose of illustration I have shown only one form thereof in the accompanying drawside elevation of an apparatus-made in accordance wlth my mventlon.
Referring to drawing I have provided a shaft 1 carrying a shell 1 on which the roll of goods is carried. The shaft is provided with any suitable device to insure that the goods being pulled off the roll will be taut. The goods pass from the shell 1 over two supporting rolls 2 and 5. Between these supporting rolls there is a doctor or smearon blade 4 in front of which is carried a body or plastic or paste 3. The goods thus treated pass into an evaporating chamber 6 in which the major portion of the solvent is evaporated and recovered. It is undesirable. to evaporate the entire amount of S01- ventas the coated oods when leaving the same pass to calen erin rolls 7, where it must be in a pliable con ition. The object.
of the calendering rolls 7 is to give the coated fabric a Imiform thickness and render the coating smooth. They need not be very large or heavy rolls as the plastic after coming from the drying chamber is prop erly coated and anchored to the -fabric but on account of the method of applying the coating in the form of a paste the goods are somewhat too rough to emboss, and the rolls 7 are used simply to smooth the plastic and give the desired uniformity of thickness. The rolls 7 may also be engraved so as to give an embossed pattern on the goods, thereby serving the double purpose of gaging and embossing the goods. I have also provided. a winder 8 which maybe so constructed as to wind up the finished product and keep the tension on the goods through the entire train of the apparatus.
In preparing coated fabrics by the wellknown coating machine, which consists of a doctor blade and a drying device, it is customary to obtain the desired thickness 'of coating by applying a number of successive layers or coatings and evaporating the solvent after each application. If a coating of the total thickness desired is applied at one time in order to reduce the number of operations, the product is not satisfactory because of pin-holes that are formed when the solvent is evaporated. I avoid by using a thicker, that is, pasty coating material and preferably pass'the coated material between calender rolls before all the solvent has been evaporated. The composition may be any 7 suitable nitrocellulose composition containing volatile solvents. It
. may also contain any suitable oil or pigment. This calendering operation reduces the coat- .a. pyroxylin coating to a fabric, a partial drier and pressure rolls for the coated fabric immediately beyond the drier.
2. In combination, means for applying a pyroxylin coating to a fabric, a artial drier and embossin pressure rolls or the coated fabric immeg iately beyond the drier. 3. In combination, means for applying a pyroxylin coating to a fabric, comprising a doctor and fabric-supporting rolls at either side thereof, a partial drier and \pressure rolls for the coated fabric immediately beyond the drier.
\ mmooe bossing' pressure rolls for the coated fabric 10 immediately beyond the drier.
In testimony that I claim the foregoing l have hereunto set my hand.
