METHOD AND MEANS OF TREATING PAPER.
Specification of Letters Patent.
Patented March 30, 1909.
Application filed June 14, 1907. Serial No. 379,031.
To all whom it may concern: Be 1t known that I, ALrnnn M. M EINCKI'I, 01' Winchester, county oi' Middlesex, State of Massachusetts, have invented an .improveformed, tun dried and calendered, the calender rolls acting upon the web alter it leaves the drying cylinders.
This invention has -l'or its object to interpose between the drying cylinders and the calender of a papenmaking machine or between the drying cylinders thereof, suitable ironing devices, which act to lay down the suriacefibers, first on one side and then on the other side of the web, without substantially compressing the web, before it enters the calender, the web, at such time, not being thoroughly dry. The iibers are. laid down and pointed in a direction opposite to the direction of movement of the web. The web, having its surface 'bers thus laid down, is in much better condition lo be engaged and acted upon by the calender rolls and by said .rolls to be substantially compressed.
The invention also has l'or its object that improvement in the art of paper making which consists in laying down the 'libers on the surface ol the web, without substantially compressing it, and subsequently substantially compressing the web having its surface fibers thus laid down.
Figure 1 shows in side elevation means embodying this invention for laying down the fibers on the opposite sides oi a web. Fig. 2 is a plan view of the ironing-devices shown in Fig. 1.. Fig. is an enlarged transverse section of one of the ironing drums shown in Fig. 2, taken on the dotted line 3-3. Fig. 4 is a modification showing more than one pair of ironing-devices. Fig. 5 is a modification showing the iro11ing-deviccs located between the drying cylinders.
As shown in Fig. 1, the web a, on leaving the drying cylinders 5, passes under a roll a, idle or positively driven, and then engages the ironing-devices (.Z, d, whereby it is iironed first on one side and then on the other, and
. then asses to the calender c which latter is of any usual or suitable construction and adapted to be operated in any usual or suitable manner. The ironing devices may, however, be otherwise arranged adjacent to the drying-cylinders, as for instance, in Fig.
5, they are shown as located between the drying-cylinders.
The ironing devices (Z, d, for the web, as herein shown, consist of hollow drums formed or provided with curved web-em gaging surfaces over which the web is drawn.
The drums may be heated by steam or otherwise, as for instance, steam pi es may be connected to the drums to deiver steam thereto. These drums are arranged at opposite sides of the web and so disposed relalive thereto as to dcllcct the web. But little deflection a ill be required to accomplish very eilicient results. As herein shown, the drums are arranged at dii'l'orent elevations and in such manner that the web is deflected in opposite ways. The drums d are adjustably connected to their end supports d, whereby they may be adjusted with respect to the web to deflect it more or less, as for instance, they may be provided with slotted cars (Z through which bolts pass which connect the drums with their supports. Furthermore, as shown, in Fig. 1, two drums are provided, yet so far as this invention is concerned any other number may be pro vided, as for instance, in Fig. 4, four drums are shown. The drums ma be arranged in any suitable manner, it on y being necessary that they shall be disposed with respect to the web so as to deflect it, in order that the Qt web may be drawn over them for the purpose of ironing it. By the arrangement herein show 11, the web is ironed first-on one side and then on the other and finally after leaving the ironing-devices passes to the calender, or as 9t shown in Fig. 5, to other drying cylinders. The web may be drawn over the,ironingdevices by the calender rolls, which will act to hold it taut, in enga elnent with the ironing-devices, and to feed der it while it is being thus fed along, or it may be otherwise held taut and drawn over said ironing-devices. It will be observed that as the web is not thoroughly dry when acted upon by the ironing-devices, such de 10!.
vices w ill act to lay down theffibers on the surface of the web, pointing them in a direction opposite to the direet1on ofmovement it and alsoto calen- 104 of the web, without substantially compress ing the web, so that when the web is subsequently presented to the calender rolls all the surface fibers will have been laid down, and when subse uently substantially compressed by the ca ender'rolls, a better finish between heated smoothing-rollers having brightly polished surfaces held in contact with each other; butsuch rollers operate to compress the Web between them and by so doing to lay down the fibres; whereas the ironing-devices, herein shown, operate to lay down the fibers on the surfaces of the web Without substantially compressing it.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent is j 1. The herein described improvement in the art of makin paper, which consists in laying down the bers on the surface of the partially dried but uncalendered web, without substantially compressing it.
