, The invention is particularly applicable to the manufacture or treatment of rubbered cords such as are used in the manufacture of cord tires, although the invention is not restricted to this. The rubbered cords referred to are convenientl first made of circular cross section and t on flattened so that the cross section is oblong. To flatten the cord it may be passed between rollers and received on a bobbin and during this operation ofi winding onto the bobbin it is particularly desirablezto maintain that portion of the cord which lies between the receiving bobbin and the rollers under a uniform tension. Similarly it is necessary sometimes towind the cord from one bobbin to another apart from flattening, and
when doing this it is required to keep the cord under uniform tension. Heretofore these winding operations have been effected by means, of a slipping clutch or belt employed for drivin the bobbin so that when the tension on t e cor'd being wound be flattening rolls) and take-up mechanism,-
that they exactly synchronize, and moreover the rate of take-up "increases as the bobbin becomes full. To maintain the tension on the cord'under treatment constant,
1 it' istherefore necessary to introduce some device which is extremely sensitive so that the least change of tension may be immediately rectified and thus what may be termed a uniform tension maintained.
According to this invention a friction drive for the bobbin or other suitable part of the machine is "used as before, but in conjunction with it mechanism is employed for varying the degree of pressure of one driving member against the other for the purpose of maintaining the tension upon the cord constant as it is fed through the machine. Preferably the mechanism employed with the friction drive is controlled by the tension put upon the cordas it is fed through the machinein such manner that it varies the degree .of pressure of one .drivi-ng member against the-other, and thus, by continually correcting any slight momentary varia tion of tension, maintains generally speaking a uniform tension on the cord.
According to one method of carrying out this'invention, the mechanism for controlling the friction drive comprises a jockeypulley, carried by a yielding support, and over which the cord is passed as it travels from .the flattenin rolls to the receiving bobbin. The yiel ing support is operatively connected with the friction drive so that ass-the length of cord feeding through the machine decreases or increases owing to variations in the rate of operation of the feed .rolls and the bobbin, the pulley will be displaced and correspondingly regulate the friction drive. The friction drive may comprise two opposed disks, .one of which is spring-controlled and ,the movements of the jockey-pulley may control the pressure of the spring so as to decrease the pressure of the corresponding friction member against the opposed member as further slip is required. With the same machine there preferably provided a gaging arm over by means of the cordand disconnecting the clutch stops the machine.
In the accompanying drawings :Figuie 1 shows diagrammatlcally a machine construoted according to one method of carrying out this invention,- and Fig. 2 shows 4 counterbalance-weight K the gaging finger J diagrammatically the same machine viewed from the right of Fig. 1.
' Like letters indicate like parts throughout the drawings. 7
The cord A on the supply bobbin B is of circular cross-section but after passing between the flattening rollers C its shape is altered so that the cross-section is oblong and it is then wound on to the receiving bobbin D. The bobbin B may be free upon its spindle but the bobbin D is driven by a frictlon clutch comprisin a driving disk E and a driven disk E 'lghe driving disk is fast upon a shaft E that may receive its motion by means of a chain and sprocket wheels from an intermediate shaft F. Free on the shaft F isa worm-wheel F that is driven by a worm G and on one side of the worm-wheel is a clutch-part F which cooperates with aslidin clutch-part F The shaft F carries one of the flattening rollers C and is geared by means of wheels H to a counter-shaft H which carries the other flattening roll C.
Secured to a rocking shaft J that is pivoted near the rollers C is an arm J 1 carrying a guide roller J 2 and gaging finger J The rocking shaft J has on it an arm J This arm is connected at J to an arm J. Another rocking shaft J 7 and an arm J 8 on this second rocking shaft has engagement with the clutch member F The rocking shaft J 7 also carries a third arm J 9 that is engaged by a spring-controlled or locking arm J having two notches J and J respectively. The cord as it leaves the bobbin B is assed over the guide roller J 2 and between 1t and It then passes between the flattening rollers C and is carried over a jockey-pulley K. The spindle of this pulley 1s carried by an arm K which in turn is supported b over a whee .L and has at its other end a The weight K is heavier than the pulley K so that it maintains a slight tension upon the cord. The wheel L is free on its spindle but has fast upon it a chain wheel L This wheel is connected by a chain L to a chain wheel L The wheel L carries a cam L and bearing a ainst the cam is an arm M. This arm is pivoted at M to a fixed support and has connection at M with the driven friction disk E that is free to slide on the shaft E A spring E acts to hold the friction disk E carried by a traversing arm N that is pivoted at N The arm 1s controlled by recip-. 'rocating mechanism N having a right and- I left-hand screw whereby the arm is moved a chain or cord K that lies.
backward and forward to feed the cord on to the bobbin. This mechanism is of a wellknown ty e and therefore does not require detailed escription, as it forms no part of the present invention. k
The operation of this machine is as folfeed rollers andthrough the medium of the rocking shaft J and its connection with the rocking shaft J 7 causes the clutch member F to be drawn away'from the member F This stops the whole machine and calls attention to the fault. The detent arm J 9 by means of its notch J holds the arm J normally in such position that the clutch F 2 F is operative, but when the clutch is disconnected the arm J 9 is moved into the If a knot or undue second notch J -and held in this position by the detent lever. Provided there are no knots or lumps the cord passes 'freely between the-gaging members and being flattened between the rolls passes over the jockey-pulley down to the bobbin D on to which it is guided by the traverse lever N and its guide pulleysN N The bobbin D however has to be driven in order that the cord may be wound thereonand requires to be driven at such a speed that it will always take up the cord as it is fed from the rollers. As the diameter of the bobbin is continually changing owin to the building up of the cord thereon it 1s necessary that some device for varying the speed of rotation must be introduced. An ordinary friction drive is very ineflicient for this purpose as such devices are very irregular 1n action and if the bobbin were driven by one of these the cord would be subjected to varying tensions, whereas it is desired that the tension shall be uniform. With the arrangement shown the tension on the cord is always maintained uniform, as an increased rate of feed on to the bobbin D, as for instance when the bobbin is partially full, causes more slack to be taken up between it and .the feed rolls and this draws down the that the bobbin D is driven more slowly. It will be seen that the adjustment is quite automatic and that the clutch E E? may be made extremely sensitive as a given displacement of the jockey-pulley K may be made to produce an esired displacement of the friction mem er Eby varying the ratio of the gearsL L and the shape of the cam L.
Instead of the wheel L obviously a counterbalance-arm may be employed, but the wheel is preferred as by using a chain or other comparatively heavy flexible connection between the jockey pulley K and the weight K, the weight of the chain may be made to approximately counter-balance the increasing ,or decreasing resistance oifered by the cam L lever M, and spring E". It will be seen that if the wheel L is rotating in the direction indicated by the arrow, the len h of chain is increasing on the right hand slde of the wheel andtherefore tends to aid the rotation of the wheel. On the other hand the cam L is offering increased resistance to this movement as owing to its eccentricity the lever M tends to rotate it in the opposite direction. The chain thus approximately counter-balances the increased resistance offered by the cam and when the direction of movement is reversed the length ,of chain on the right hand side of the wheel helps to counter-balance the tendency of the cam L to rotate in a counter-clockwise direction under the action of the lever M and treatment of lengths of material the combination of, a 'receivin bobbin, a driving member, a driven mem er having frictional engagement with the drivin that is operatively connecte with the receiving bobbin, means independent of said bobbin for feeding material thereto, andmeans controlled by the material as it isfed through the machine to .vary the pressure of one friction member against the other in proportion to any variatlon of tension on the material in the machine and for the purpose of correcting such variation,
