referring now to fig1 , there is shown a large round baler including a support 12 , a baling chamber 14 and a wrapping arrangement 16 . the larger round baler 10 is used in agriculture or in the trade and is applied for the manufacture of cylindrical bales which are wrapped at the end of the baling process with wrapping twine 18 and are thereby held together . large round balers are known in themselves sufficiently , for example , as part of the model series john deere 575 so that details need not be described here . the support 12 is composed of a chassis , a tow bar and the like , but is represented in the drawing by side walls , 20 , that enclose the baling chamber 14 at its eds . the walls 20 are connected by struts 22 with corresponding walls on the other side , so that the baling chamber 14 is configured as a stable structure . te wrapping arrangement 16 is also retained between the walls 20 and around its circumference by rolls 24 , of which only a single one is shown . nearly twenty of such rolls 24 extend in the direction of the struts 22 and are arranged in a circular pattern that permits a first , lower gap or slot for the inlet of the crop to be baled and a second , upper gap or slot for the inlet of wrapping twine 18 in each case into the baling chamber 14 . in the present embodiment , the baling chamber 14 is configured as fixed in its size , but this is not mandatory . rather , the baling chamber 14 could be of variable size and / or be enclosed by belts and / or bar chains . in the baling chamber 14 , a bale , not shown , is maintained in constant rotation , so that at the end of the baling process wrapping twine 18 is introduced between the rolls 24 and is grasped by the bale and carried along . the wrapping arrangement 16 provides the supply of the wrapping twine 18 into the baling chamber 14 , its sideways guidance on the circumferential surface of the rotating cylindrical bale and its separation as soon as it has been wrapped around the bale with wrapping twine 18 , all of this is sufficiently known and shell therefore be described only to the extent that this is necessary for there understanding of the present invention . in the present embodiment the wrapping arrangement 16 contains two twine dispensing arms 26 , that insert wrapping twine into the baling chamber 14 from above the roll 24 , as pictured . instead only a single twine dispensing arm 26 could be provided . each twine dispensing arm 26 can assume three positions , namely , a rest position , a wrapping starting position and a cutting position into each of which it is guided by a motor . in the rest position , the twine dispensing arm 26 extends approximately parallel to the longitudinal direction of the rolls 24 . in the wrapping starting position , that corresponds to the position shown in fig1 , the wrapping twine 18 is guided into the upper slot between the rolls 24 so that it drops downward into the baling chamber 14 and is grasped there by the rotating cylindrical bale and is carried along . it is important that the wrapping twine 18 hangs downward far enough so that it can be grasped . therefore the free end of the wrapping twine 18 hanging downward must not be bent or become entangled with the twine dispensing arm 26 . in the cutting position , the twine dispensing arms 26 extend approximately perpendicular to the longitudinal axis of the rolls 24 and are in an operating position with the cutting arrangement 28 . in this position , the wrapping twine 18 is held fast so that it is in contact with the circumferential surface of the cylindrical bale under increased tension , and is subsequently torn off or cut off . due to the high tension , the cut end section tends to recoil and to move uncontrollably . the twine dispensing arm 26 is provided with a guide component 30 that guides the wrapping twine 18 over part of its length and thereby prevents it from performing an uncontrolled movement that can lead to it not reaching the slot in the baling chamber 14 . although this danger is greatest with a twine dispensing arm 26 extending horizontally or generally in the horizontal direction , the guide component 30 can also be helpful with a more erect arrangement of the twine dispensing arm 26 . regarding the configuration of the guide component 30 , reference is made to fig2 through 6 , each of which shows the otherwise free section of the twine dispensing arm 26 with guide component 30 in an end section of the wrapping twine 18 . according to fig2 , the guide component 30 is configured as a link chain that is attached to the underside of the tube - shaped twine dispensing arm 26 by a clasp 32 . in this case , the guide component 30 contains five links 34 of which the first , upper link is clamped between the clasp 32 and the twine dispensing arm 26 and the remaining four links hang downward . the wrapping twine 18 is threaded through the lower links 34 so that the wrapping twine 18 is caught during the recoiling after the cutting process and cannot wrap itself around the twine dispensing arm 26 , for to do so it would have to carry along the guide component 30 , that is , the heavy chain . according to fig3 , the guide component 30 is configured as a bow , that extends downward and is provided at its lower end with a flexible collar 36 . the bow may consist of metal or plastic and be attached with screws , clamped or snapped in place or attached with adhesive . the solution according to fig4 differs from that according to fig3 in that in place of the collar 36 , a hose 38 is snapped on . the hose 38 can be fastened with a clasp or a clamp , no shown , by means of adhesive or in some other manner . depending on the energy of the wrapping twine 18 that can be expected during its upward recoiling , the hose 38 should be supported by steel inserts or otherwise configured sufficiently stiff . basically , a water hose of one inch diameter could be appropriate . fig5 reveals a variation in which a plastic - coated steel cable is fastened at the upper end y means of a cable clamp 40 to the free end of the twine dispensing arm 26 and is provided with a loop 42 at its lower end through which the wrapping twine 18 extends . finally , fig6 shows an embodiment in which a helical spring is used as a guide component 30 . this guide component 30 is fastened to the twine dispensing arm 26 by means of a carriage bolt 44 . all embodiments have in common that the guide component 30 extends only over a part of the length of the wrapping twine 18 hanging downward , for example , over a quarter of its length . having described the preferred embodiment , it will become apparent that various modifications can be made without departing from the scope of the invention as defined in the accompanying claims .
a twine dispensing arm of a wrapping arrangement for a large round baler is provided with a dispensing end defined by a component which , at the time when twine wrapped about a bale is separated from a length of twine carried by the arm , prevents a length of recoiling twine from becoming entangled or incorrectly oriented for a subsequent wrapping cycle .
