Appncatioii mea December 12,1931.v serialv No. 580,711.
My invention relates to certain improvements in FourdrinierV paper-making machines.
One object of my invention is to provide means for taking up considerable slack of the making wire of thel machine so that when the wire is slack it can be readily removed laterally from the machine and it ris desired to replace the wire with a new wire, which can be also placed in position, and the slack of the wire can be taken up sufficiently to make the wire taut.
A further object of the invention is to provide two take-up mechanisms, one actuated from a single operating means.'
A still further object is to so design the take-up mechanism that one of the take-up rolls will balance the other take-up roll. Y
The making wire of a F ourdrinier papermaking machine must be replaced at frequent intervals by new wire. These wires are endless and it has been the usual practice to adjust the breast roll or remove the roll entirely so as to allow enough slack in the wire that it can be readily removed and a new wire placed in position. This is a very delicate operation as the least little imperfection in the wire makes it useless in making paper, especially high grade papers.
By my invention the rolls over which the wire passes are not adjusted or removed, and
the slack of the wire is taken up by mechanism located under the machine and which bears upon the return run of the wire.
In the accompanying drawing:
Fig. l is a side view of a paper-making machine, illustrating my invention;
Fig. 2 is an enlarged view of part of Fig. 1, with the slack take-up mechanism in position when the wire is tightened and ready for the making of paper; and f Fig. 3 is a view similar to Fig. 2, showing the slack take-up mechanism in position to allow considerable slack in the wire, so that the wire can be readily removed from the machine without removing the breast rolls or other parts of the machine.
l are standards which support the frames 2 and 3 of theFourdrinier machine. The
machine is divided into two sections, the first vmounted on the floor.
section 4 being the paper-forming section and the section 5 being the suctionboX. section for removing surplus ywa'ter'from the formed paper. 6 is a seriesofrollers which support the wire 7, whileI the paper isfbeing formed. 8 is the breast roll at the forward end of vthe machine and 9 is the'couch roll jaround which the wire-'passes after leaving ythe suction boxes.
10, 11 and 12 are guide rollsfor the return run of the Wire. The guiderolls 11 and 12 are mounted in bearings depending from-the frame 2, while-the guide` roll 10 isl supported on suitable bearings 13 is the take-up yof the ordinary type mounted on arms 14 which CE.j
are raised and lowered by ashaft 15 geared 7 vto the` arms and-provided with a hand-wheel.
v16- and v17 are the take-up rolls forming part of 4my present invention. The roll 17 is vmounted'in bearings 18 on arms 19 carried by -a shaft 20 mounted in bearings 21, and secured vtothe shaftis an arm 22 connected by a rod. 23 to an arm 24 on a shaft 25. Secured -to the shaft'25 are armsA 26 carrying bearings 27 forrthe roll 16. The two lrolls are very heavyv and by the construction described abovethe one roll balances the other, so that v-it takes -comparatively little power to shift Vthe rolls to take up the wire orto slacken it.
The arms 22 and 24 and the connecting rod 23.are at the back of the machine.`
Qn the shaft 25 is toothed lsegment28, which meshesr with the pinion 29 on, a shaft V30. On this shaft is a Worm-wheelV 31, with which meshesa worm I32 l,onaf longitudinal I operating shaft 33 mounted in suitable bearings on the frame 3 at the'back'I of the machine. At the opposite end of the shaft is a beveled gear-wheel 34, which 'meshes iwith a beveled gear wheelf35 ona transverse operating shaft 3 6, on which is av hand-wheel 37 at the frontend of the machine. By the above construction,4 when-the roll V16 is raised to slacken the wire,` ther'oll 17 is lowered to increase `the slack inthe wire as shownv in F ig.'3, and when the roll lfi's lowrolls are'operated simultaneously in opposite directionsy on turning the handwheel 37 of the operating shaft 36, the motion being imparted through the shaft 33 and wormwheels, pinion 29 and segment 28. The takeup roll 13 can be lowered when it is desired to place additional slack in the wire and can be raised until the desired amount of tension is secured. My improved apparatus is very simple and is quickly operated and provides sufficient slack in the wire to allow the Wire vto `be readily removed from the machine and a new wire placed in position.
I claim:
l. The combination in a Fourdrinier paper making machine, of a making wire; means for guiding the wire throughthe machine; two take-up rolls arranged to move in opposite directions for either taking up the slack or providing slack inthe making wire and means for operatingthe two take-up rolls in unison.
2. The combination in a Fourdrinier machine, of a paper-forming section; a suction boX section; a roll at either end of the machine a making wire arranged to pass around the two rolls and over the forming section and the suction boxes; two take-up rolls arranged to move in opposite directions for either taking up the slack or providing slack in the making wire; and means for operating the two rolls in unison.
3. The combination in a Fourdrinier machine, of a making wire; means for supporting the wire in the machine; two take-up rolls; two shafts; arms on each shaft on which said take-up rolls are mounted, each shaft having a second arm and a rod connecting the two last-mentioned arms; an operating shaft having a hand-wheel; and gearing between the hand-wheel and one of the firstmentioned shafts, so that on turning the hand-wheel in one direction the one take-up roll will be raised and the other lowered, and when the hand-wheel is turned in the oppo- .site direction the movement of the rolls will be reversed.
4. The combination in a Fourdrinier machine, of an endless making wire; means for guiding the wire through the machine; two transverse shafts; arms on each shaft; a takeup roll carried by the arms of each shaft; a short arm on each shaft; a rod connecting the two short arms; bearings for said shafts; a toothed segment on one of said shafts; a pinion meshing with the segment; a shaft 0n which the pinion is mounted; a worm-wheel on said shaft; a Worm meshing with the worm-wheel;a longitudinal shaft on which the worm is mounted; an operating shaft; beveled gearing between the operating shaft and the longitudinaly shaft; and means for roll is lowered the other roll is raised to take up the slack in the wire, and when the movement of the operating shaft is reversed the first-mentioned roll is raised and the other 1,885,1eeVA roll lowered to allow the wire to become slack.
5. The combination in a Fourdrinier paper-making machine, of a making wire; means for guiding the wire through the machine; two take-up rolls located under the machine and arranged to take up the slack on the return run of the wire; two transverse shafts spaced apart; two arms 0n each shaft, one of said rolls being mounted on one pair of said arms, the other roll being mounted on the other pair of said arms; Van arm on each shaft at the back of the machine; a rod connecting the two last-mentioned arms; a transverse operating shaft having a handwheel at the front side of the machine; and .means connecting the said operating shaft to one of said transverse shafts, said means being located at the rear side of the machine, so that when the operating shaft is turned in one direction the rolls will be actuated in unison to take up the slack of the wire and when the shaft is turned in the opposite direction the rolls will be moved so that sufficient slack will be provided in the wire to allow it to be removed from the machine.
