WET-WEB CARRIER FOR PULP AND PAPER. MACHINES.
Application filed April 1,
, Carriers for Pul and Paper Machines, of
which the following is a specification.
My present invention relates to web picking and web carrying means for all kinds of papel-making machines, or other ma- Mchinos which are designed to handle plastic pulp in a web or sheet.
The objectof this invention is to provide web picking and web supporting and carrying'means which will withstand greater strains, and wear longer, than will the usual papermakers felts now utilized forl such purposes. In the accomplishment of my object I make use of a strong, resilient, cushioning base provided with a covering of woven fabric, "preferably of wool, or with a plurality of wool yarns laid on the base in anydesired attern.
Myl improved we -picking' and web-carrying means is illustrated by the accompanying drawings, in which:
Fig. ,l is a diaI am of. a pulp or paper machine equippe in accordance with this invention; Fig. 2 is a plan view of a portion of one of my improved web-carrying means; Fig. 3 is a cross-section of the same; Fig. 4 is a plan and Fig. 5 is a crosssection of one form of my invention.
The same reference characters refer to the same parts throughout the views.
Referring to the drawings, B represents the cushioning base which may be of any suitable resilient material, such as rubber.
This base may be either solid or perforated, and either plain or reinforced, as for instance by having a suitable fabric incororated therein. To the lto vof the cushioning base B, is laid, an strongly at tached thereto, a covering C of woven fabric or of awplurality of yarns laid in any desired pattern, as for exam le, the yarns c, c, laid side hy side lengthwise of the base as illustrated in Figs. 2 and 3. This covering may be secured to the base in any suitable manner, as for example, by the use of a strong adhesive, or bybeing rolled or otherwise pressed into the surface of the rubber while it is in a plastic state.
My invention is intended to supersede the use of all kinds of woven felts such as are 1924. Serial No. 703,368.
now used in the manufacture of pulp and paperfor the purpose of handling the web of pulp while in almoist state, and which are known in the artas paper makers feite. My
invention is adaptable to all uses to which such felts are put-from the initial removal of the web of wet'pulp from the web form* ing device, t'o `its delivery tothe dryers.
When my improved web-carrier to be used for initially removing the web ef pulp from the web forming cylinder of a cylinder machine, or for carrying the plastic web from the web forming wire of a Fourdrinier machine, to and through the press rolls, the cushioning base is to be perforated for the purpose of permitting the free escape of.
water from the web when it is acted upon by those rolls. The covering which is laid on and attached to this cushioning base (which is to take the place of the usual drainage felt) will be composed of a plurality of smoothly laid yarn, or a smoothly woven and laid fabric. Thesurface of either type of covering being given a surface finish which will produce the desired finish on the web being produced.
When my improved web carrier is to be used in Vplace of what is known as a pick up felt, one purpose of which is to pick the web of jmoist pulp olf of the drainage felt and delivervit through the press rolls to the dryers, the cushioning base will be without perforations and the covering will be composed of a plurality of smoothly laid yarns, or a smoothly woven and laid fabric, in
. either case the surface will not be napped.
While I now prefer to make use of a covering composed of a plurality of individual yarns, a woven fabric may he substituted on either the solid or the perforated cushion base; the finish given the working face of the fabric depending on the class of service for which it is to be used.
A web picker, Aor a drainage type of web carrier, constructed in accordance with my invention is comparatively inexpensive to manufacture, and will withstand wear for a much longer period than will the usualA papermakers vfelt designed for the same service. Making use as I do of a cushioning base which lends itself to easy reinforcement, it is a simple matter to so construct my improved web carrier that it will withstand lnore than the usual strain to which it will be sub'ected in the service -for which it is designe and I am thus enabled to greatly reduce the cost by reducing the amount of Wool which is normally required to produce the usual wet web carrier or papermakers felt. l t Perhaps the greatest advantage of my irnproved Wet web carriers lies in the fact that .they are free from virtually all of the defe'cts which are inherent in the usual papermakers felts used for the same purposes.
prevent any appreciable' change in therelative positions of the yarns forming the 4 covering, or any appreciable change in the porosity or available drainage through the carrier. In the usual felt carriers a change in the relative positions of the yarn forming the fabric, such as takes place when such a carrier does not run true, will change the effective porosity of the carrier.
I claim:
` 1'. In pulp and paper machines the com.- bination of a web forming device, press rolls, and conveying means adapted to conresilient'materiah' such as rubber, having a covering of yarns attached to the surface thereof.
2. In pulp and paper machines the combination of a web forming, device, press rolls, and conveying means adapted to convey the Wet web of pulp from the "web forming dc- 'vice to and between the press rolls said means including a perforated endless base of a resilient material, such as rubber, having a covering of yarns attached to the surface thereof.
3. A Wet web carrier for use in p'ulp and paper machines, comprising an endless base of resilient material, such as rubber, with a covering of yarns securely attached to the surface thereof.
4. A Wet Web carrier for use in pulp and paper machines, comprising a perforated endless base of'a resilient material, such as rubber, with a covering of yarns securely attached to the surface thereof.
5. A Wet Web carrier for use in pulp and paper machines, comprising a lperforated endless base of a resilient material such as rubber with a Woven fabric securely attached to the surface thereof. l
In testimony whereof I have affixed my signature.
