This invention relates to multiple roll calenders, particularly such as are intended for use in rubber manufacture. Gne'object of the invention is to provide an adjustment for calender rolls adapted to calenders having any desired number of rolls. A further ob ject is to provide novel and simple means for adjusting the spacing, of any adjacent pairof calender rolls without affecting the ad-' justment of the remaining rolls. Referring to the drawings: 1
Fig. 1 is a diagrammatic vertical section through a fourroll rubber calenderv embodying my invention, and I Fig. 2 is a diagrammatic view showing the application of the invention to a six-roll calender. v Referring to the construction shown in Fig. 1, the calender rolls are mounted upon a frame 10, there being one of these frames at either end of the calender as is usual. Jenn naled for rotation in these frames is a roll 11, the axis of which remains fixed. Above this fixed roll is mounted a roll 12 journaledin boxes 13 made vertically adjustable by means of screws 14. At the bottom of the calender is a roll 15 journaled in boxes 16 vertically adjustable by screws 17. The adjustment of these latter two standard manner. Mounted above roll 15 is a roll 18 journaled in boxes 19 having arcuate faces sliding in ways 20 in the frames. The surfaces of the boxes 19 and of the ways 20 are formed on arcs having as an approximate center the axis of roll 7 15. By means of screws 21 and 22 the position of each box 19 can. be varied and maintained in adjusted position in the ways 20.
As the calender shown is suitable for the manufacture of so-called weftless cord fabric I as well as for the production of rubber sheets,
a comb 23 has been shown together with a roll 24 adapted to receive a sheet of cords 25 arranged in a spaced relation and press them against a rubber sheet upon roll11. In operrollsmay be made in any .serial no. 294,646.
ation a-feed'tof rubber 26 is placed between rolls ll and 12 anda feed 27 between rolls 15' and 18. The upper two rolls form therubber from feed 26' into a sheet 28 while the lower two rolls form the rubber from feed 27'into a sheet 29,-thetwo sheets thus formed being joined into one composite sheet,together with cords25 if desired, between the: rolls 11 and 18. it will be understood that the rolls may be rotated in the direction of the arrows by any suitable orstandard gearing, the nature otwhich is not affected by the method of adjustment forming my present invention.
It will be observed that-the roll 18 is offset from the" line of centers ofrolls 11 and 12.
This is desirable although not absolutely necessary asit permits the adjustment of journal boxes 19 in ways 20 to have a greater effect in varying the spacing of rolls 11 and 18 than'would be the'case were the rolls all in line. 1- The adjustment of the spacing between rolls 11 and 12 and betweenrolls 15 and 18 is accomplished in the usual manner by screws 1 1 and 17 respectively. B01118, however, being moved by the adjusting screws 21 and 22 in an arcuatepath having as an approxlmate center the axle of roll 15, does not in its movement ofadjustment vary the spacing between itself and roll 15, but only the spacing betweenitself androll 1-1, By this means, which requires a minimum of calender parts, the spacingb'etween any two adjacent rolls may be varied without chang ing the adjustment between-any other two rolls. p
In Fig. 2-1 have shown diagrammatically the'application of my invention to a-cal'en der having six rolls.
number .of rolls than this will be apparent to those skilled in the art. In the example of Fig. 2 the roll 31 is fixed. That is to say, its axis is non-adjustable.
The application of the invention to calenders of greater or less V The roll -32 is vertically adjustable inthe standard mancenter the axis of roll 83.
ner. Roll 33 is likewise vertically adjustable in the standard manner. Roll 34 is adjustable upon an are having as an approximate Roll 35 is similarly adjustable about the approximate center of roll 34 and roll 36 is adjustable about the approximate center of roll 85. The ad justment of any adjacent pair of rolls in this construction can be carried on without attecting the spacing of any other pair of rolls. i i
In both the four and six roll constructions I have spoken-of certain of the rolls being capable ofadjustment in an arcuate path having asan approximate center the axis of an adjacent roll. the center of this coincident with the but due to the fact self has a slight It is preferable to keep arc as nearly as possible axis of the adjacent roll, that the adjacent roll itpath having as an approximate center the axis of an adjacent rubber sheeting roll.

transverse movement of adjustment it will be impossible to maintain Y the desired relation with mathematical exactness at all times. Since, however, the thickness of the rubber sheets generally produced is only a matter dredths of an inch, thecoincidence of the centers Will be so close that the movement ofthe arcuately adjustable roll will produce no appreciable effect uponits spacing from the roll about whose axis it swings. I
Having thus described my invention, I claim: 1. A rubber calender having a'plurality of rubber sheeting rolls one of which has a fixed axis,
the axis of one adjacentroll, means for adjusting transversely the axis of a roll remotefrom the fixed roll, and means for adjusting the axis of the roll between thefixed roll and theremote roll in an are having the axis of theremote roll as an approximate center.
2. A rubber calender comprising a plurality of rubber sheeting rolls at least one of said rubber sheeting rolls being constrained for transverse movement inan arcuate path having as an approximate center the axis of an adjacent rubbersheeting roll.
3. A four, roll calender having the axis of one intermediate roll fixed, means for adjusting the adjacent end roll toward and away from the fixed roll, means for adjusting the remote end roll transversely of its axis, and means for adjusting the second intermediate roll in an arcuate path having as an approximate center the axis of the remote end roll.
a 4. A four roll calender; having the line of centers of the upper two rolls substantially vertical and the line of centers of. the bot tom two rolls substantially vertical but offset from the line of centers of the upper two rolls, means for adjusting the top roll vertically, means for adjusting the bottom roll vertically, and means for adjusting one of the intermediate rolls in an arcuate path of a very few hunmeans for adjusting transversely
