APPARATUS FOR OPERATING 0N PAPER AND OTHER FABRICS.

Application mea Aprn 17, l1920. serial No. 374,636.

This invention relates to a new apparatus for operating on paper.

One object of the invention is the provision of improved means in the .production of paper that shall be stretchable in twov directions, that is, longitudinally and transversely. Another object of the vinvention is the production of such paper by forming crinkles crosswise of the paper after it has been corrugated lengthwise. Another object is to form in the paper such longitudinal corrugations and cross crinkles 'during the forward travel of the paper in the Web. Anotherobject is to operate on thev paper with no more moisture in it than is .properlyrequired to form the crinkles and thus reduce the cost of subsequently drying the paper. In some cases, the paper may be operated upon without the previous addition of moisture.` Other objects of the invention` will-appear from thei following description. u v

The invention consists ofthe structure and arrangement and in the steps of operation hereinafter set forth.

In the accompanying drawings, forming part of this specification, and in which like reference numerals .designate corresponding parts, the apparatus is shown in one of its various embodiments. v v

Fig. 1 is a central sectional elevation of a suction crinkling cylinder and associated parts.

Fig. 2 is a view of said cylinder, partly in section, withits associated doctor, lookinfr from above.

Fig. 3 is a diagrammaticview of the series -of corrugating rollsv shown in Fig. 1.

Referring to the .particular structure, as shown in the drawings, 1 is .a perforated suction cylinder mounted on a fixed tubular shaft 2 which is open to the interior by the openings 3. The open end of the shaft 2 connects with a pipe 4 leading to a suitable suction pump 5 which may be driven by an electric motor 6. The plpe 4 is provided. with `a relief valve 7 whlch may be operated to regulate the suction in the ipe 4. 8 is a suction box movably mounte on the shaft 2 and communicating therewith through the openings 3. It is held in place set screws provide for the circumferentialv adJustment of the suction box 8 so that the `\-area of pressure on the paper may be adteeth or serrations 13 which fit into the grooves 11 of the cylinder. Cooperating with the cylinder 1 is a set of corrugating rolls 14, 15, 16,17, 18 and 19. The paper on the cylinderpasses underneath these rolls in the order named. Roll 14 is provided on the shaft 2 by set screws 9 and 10. These with `a single bossv 20 arranged to enter the central groove of the cylinder 1. Roll 15 is provided with a'u middle boss inalignment with the boss 20 and with two additional bosses all similar to boss 20 and arranged to enterthe ,grooves on either side of that in which boss' 20 operates. The remaining corrugatingrolls are similarly provided with bosses, each roll having bosses in alignment with those on the preceding roll V.and two bosses in addition, the last roll 19 having as many bosses asV there are grooves in the cylinder 1. These corrugating rolls act to press the paper down into the grooves 11 and they a'ct upon'the paper progressively .from the middlev outward.-

21 is the web of paper passing through the apparatus. After it meets the doctor 12, it emerges aslthe web 22 provided with crinkles across its' surface vand with corrugations longitudinal thereof. The web 21, before entering the apparatus, may be in a Hat smooth state. In this case the corrugating rolls 14 and 19 progressively press it into the grooves 11 of lcylinder 1 and thereby form corru ations in it. The suotion ebox 8 causes t e paper to be held on the cylinder and in the grooves thereof by air pressure immediately in advance of and yat the 4doctor 12. Thisfv pressure on the paper or holding ofthe paper down on the cylinder resists the stripping action of the doctor. It also enables the paper to be suitably crinkled in a drier state than would be otherwise possible. If desired, the web 21, before being fed to the cylinder l, may previously have been provided with longitudinal corrugations. In this case, the corrugating rolls 14 to 19 may act merely to further set the. corrugati-ons so previously formed or they may act to increase the depth and sharpness of such corrugatlons. Furthermore, in cases Where the paper 21 has been previously corrugated, or in cases Where it is not desired'to form corrugations in theY paper, the corrugatingrolls 14 to 19, as elements cooperating directly wlth the crinkling cylinder 1, may be-dispensed with. Rolls 14 to 19 may be made of any suitableO material, yielding or otherwlse. They may be friction-driven from cylinder 1 or they may be driven from any other source of power. A l

23 is a tank cont-aining hot Water through which the paper may pass beneath submerging rolls 24 if it is desired to Wet the paper beforefit passes on toi the cylinder 1. Other means for moistening the paper maybe used.

' 25 is a guide roll for the paper on its Way to formed^in t e pa the cylinder 1.

lVhilel it is preferred that the 'supporting surface for the paper in cooperation with the corrugating rolls and in cooperation With the doctor or crinkle-forming abutment be in the form of a cylinder, the invention is not restricted to such formof supporting surface. Andvwhile it is preferred to use fluid pressure, and particularly'air pressure provided by a suction box, to hold the paper on the cylinder and in the grooves thereof, andl particularly immediately in advance of or at the doctor, the invention contemplates anyA means for Athus holding the 'paper or for applying pressure to the paper in cooperation with a grooved supporting surface'and a doctor or other crinkle-forming means. By crinkling paper that has been previously corrugated in accordance with this invention, the crinkles extend across the paper in zigzag-lines and therefore, of themselves, provide for a certain transverse stretchability of the paper.

Such transverse stretchability is increased b the longitudinal corrugations r. It will be seen that the present invention 'contemplates an extension or new applicationv of the invention set forth in my formen application Serial'No. 267,430, filed Decemv ber 19, 1918.
