PAPER MAKING MACHINE Application filed February 26, 1930. Serial No. 431,416.
This invention relates to paper making machines.
It has for its object to construct an improved form of ironing apparatus for acting on the web after it has passed through some of the calendering rolls.
An object of the invention is to provide a simple and easily adjusted means which will produce a smooth polished finish on the n Web. I11 order to get such a finish, it is necessary: first, that there be a smooth surface to do the ironing; second, that the process be conducted at about 800 degreesFahrenheit; and third, that the web be sub- 1:, jected to a rubbing action. The methods heretofore employed for finishing a. paper web do not comply with the requirements as set forth and result in a poorly finished product. flu The invention in its illustrated form consists of a driven roll covered with some soft material, as felt, which carries the web; a concave, hollow shoe highly polished on the inner surface which abuts the web, through 2.; which shoe a heating medium as steam, air, gas, or electricity can be circulated to effect the ironing; and a mechanism capable of adjustment to provide any desired pressure between the shoe and the roll. so In the drawings which illustrate my in vention, Figure 1 is a side elevation of a calendering section of a paper making ma chine with one of the improved ironing devices attached thereto. Figure 2 is a front :5 elevation of the same calendaring machine. Referring to the drawings1 designates the frame of the calendering section of a paper making machine. Mounted in the frame of the machine in the usual manner are the rolls 2 around which the web (1 passes. A roll 3 tapering slightly towards the ends is covered by felt 4. This roll is mounted in the bearing 5 and it serves to carry the web past a hollow shoe 6 and also as a bearing surface against which the hollow shoe presses. This shoe has the intake and exhaust pipes 7 for carrying the heating medium which, in the present instance, is preferably steam. The temperature of the shoe is preferably about 800 degrees Fahrenheit. The face 8 of the shoe is concave and highly polished for ironing and glossing the web. The shoe is supported in place by mechanism comprising ears 9 on the back of the shoe, connected by pins 10 to arms 11 mounted on pivots 12. Brackets 13 are secured to the frame of the calendering stack by bolts 14. The upper parts of these brackets have holes through which the springs 15 and also the plungers 16 pass. Adjusting screws 17 which have knurled heads serve to hold the plungers 16 against the spring .so that any desired pressure may be obtained between the shoe 6 and its co-operating roll 3.
In operation the web is passed through some of the calendering rolls 2, from which rolls it passes to the felt covered roll 3. After the web passes between the covered roll and the heated polished face of the shoe, it returns to the remaining rolls in the calendering stack. The heated smooth face of the shoe pressing against the web and the sliding action of the shoe on the'web polishes and glosses the Web. As the degree of ironing and glossing depends on the pressure and heat applied, the varying of the adjusting screw 17 and of the quantity and temperature of the steam supplied to the shoe produsges the desired effect in the finished paper we While I have illustrated and described in detail one embodiment of the invention, it is to be understood that changes may be made therein. I do not, therefore, desire to limit myself to the specific construction illustrated 55 but intend to cover my invention broadly in whatever for-m its principles may be utilized.
I claim:
1. A paper making machine, comprising a web carrying roll, a heated hollow shoe cooperating therewith to iron the web, and means for applying said shoe to the web under pressure. 7
2. In combination, a calendering stack, an isolateddriven roll and a burnishing and smoothing device co-operating with said roll.

6. In combination, a oalendering stack, an isolated driven roll, a hollow shoe, said shoe having a concave face for co-operating with said roll, and means for heating said shoe, said shoe having a polished metal face for ironing.
7. In combination, a calendering stack, an isolated driven felt covered roll,a hollow shoe, said shoe having a concave face for 00- operating with said roll and means for heating said shoe, said shoe having a polished metal face for ironing.
8. In combination, a calendering stack, an isolated driven felt covered roll, a hollow shoe, said shoe having a face for co-operating vylith said roll, and means for heating said s 0e.
9. In combination, a calender'ing stack, an isolated driven felt covered roll, said roll having a diameter which tapers slightly towards the ends, a hollow shoe, said shoe having a smooth, concave face for co-operating with said roll, and means for heating said shoe.
10. In combination, a web carrying roll, a smooth, concave, hollow shoe co-operating therewith, and means for securing said shoe against said roll at any desired pressure.
11. In combination, a calendering stack, an isolated driven roll, a burnishing and smoothing device co-operating therewith, and means for securing said device at any desired pressure against said roll.
12. In combination, a calendering stack, an isolated driven roll, a shoe co-operating therewith, said shoe having a rear projection, a pivoted member co-operating with said projection, and means for holding said member and shoe at a constant pressure against said roll.
13. In combination, a calendering stack, an isolated driven roll, a shoe co -operating therewith, said shoe having a rear projection, a pivoted member co-operating with said projection, a spring, plunger, and adjusting screw co-operating with said pivoted member, and a stand co-operating with said adjusting screw and spring, said stand, adjusting screw, spring pivoted member all cooperating toxhold said shoe at a constant variable pressure against said driven roll.
In testimony whereof I have afliXed my signature to this specification.
