Description

THREAD SUPPLY DEVICE DESCRIPTION S The object of the invention is a device for feeding yarns, especially elastomer yarns. Especially in knitting machines and machines for knitting, in the production of elastomer yarns these can not be extracted from the bobbins of a bobbin case.

Due to the longitudinal extensibility of the elastomer yarns, it is more necessary to drive the bobbins, in such a way that the yarns feed the knitting stitches with a yarn tension that is reduced and constant over time. For the drive of the wire coils, devices are used exist in large numbers in the corresponding knitting machines or knitting machines. The devices are provided in knitting machines or knitting machines as separate units and fixed with the corresponding jaws in a frame section of the machine. the machine provided for it. These devices are supplied for existing knitting machines, if needed, as an accessory and mounted on them. This must be done in the simplest and fastest way possible. For document DE 32 33 fi69 C2, there is a known P5 device for feeding elastomer fibers for knitting machines or knitting machines, having a housing to be fixed in the frame of a machine and enclosing an interior enclosure. The casing is traversed by two actuating cylinders, each of which is arranged horizontally and parallel to spaced distances from each other. Each drive roller comes out on both sides of the housing. Bearings are provided in the housing for the rotational mounting of the drive rollers. A toothed belt pulley with a vertically oriented shaft is used to drive the drive cylinders. It works by means of a conical wheel drive provided in the inner enclosure of the housing and a toothed belt in both drive cylinders. The pulley for the toothed belt mentioned above, arranged on the outside of the housing, is used for driving the entire device and is in conjunction with a toothed belt, which drives the pulleys for toothed belt of several devices arranged in the knitting machine or for knitwear. The housing has flat surfaces with openings, which are traversed by the drive cylinders. In the assembly of the device the drive cylinders are passed through these openings. For the utility model with the publication number TW 167 394 a device is known for feeding elastic threads with which two parallel discharge cylinders, spaced one from the other, mounted on a holding body, configured Solid each of them in a pair of ball bearings. The thickness of the solid body corresponds approximately to the thickness of the two ball bearings arranged directly next to one another. Each of the drive cylinders is formed in one piece with a toothed belt pulley, which is disposed laterally together with solidly configured support. A toothed belt runs on the toothed belt pulleys of both drive cylinders and is used to drive them. Due to the tension of the driving toothed belt, which runs on one side, and the narrow contiguous assembly of the drive cylinders by the ball bearing, the alignment of the drive cylinders is limited. By the utility model TW & 2 606 a thread feeder device for the supply of elastomeric yarns having a split housing is known. Two drive cylinders are provided in the wire feeder device, each of which ends at both ends of the housing, which are separate and parallel and rotatable in the housing. For this, each drive cylinder is provided with a support device, a bearing cap and a belt pulley arranged in the immediate vicinity. The housing is divided along a plane, the drive rollers being perpendicular thereto. One of the two parts of the housing has two cylindrical housings open on one side, which can accommodate the support devices on which the actuating cylinders are seated. The housings are provided on the edge side, each with three threaded holes for housing the bearing caps. A toothed belt for the synchronized drive of both drive rollers runs laterally next to the support elements through the pulleys for the belt. The toothed belt is covered by the other part of the casing, which does not contain another means of support. The above limitations apply to this device. In addition, the bags for housing the support devices have been configured in one piece and must be constructed with the corresponding precision. Yarn feeler devices are needed in large numbers in knitting machines and knitting machines. Therefore, it is intended to have wire feeding devices in the required quality at the most advantageous price possible. Furthermore, it is intended that the yarn feeding devices can be assembled and disassembled in the simplest possible manner. As a result, the basic object of the invention is to construct a wire feeder whose support and drive cylinders are maintained in good alignment with each other and which allows simple assembly and fabrication. This object is achieved by means of a device for feeding wires with the features of claim 1. The device for feeding wires has two support cylinders, of which at least one is driven. The support rollers are arranged at such a distance from each other that the minimum distance between their peripheral surfaces is smaller than the outer diameter of the tube of the reel to be unwound. In operation the coil, from which the elastomer thread has to be removed, is located on the support cylinders that run in the same direction. By separating the housing in two parts along a seal, which passes through the recesses, the housing is subdivided, in the mounting position, into at least one upper part and one lower part. This means that the seal passes through or over the edge of the openings from which the support cylinders exit from the housing, of which at least one is driven. The support cylinders can be placed directly from the joint or provided with support elements in the recesses, which have an opening accessible from the joint. The part of the housing, lower in the use position, is formed in such a way that it is possible to place support elements and transmission elements with the handle open in the lower part of the housing. In this way, assembly is possible, that is, assembly of the device through the introduction of the corresponding parts in the lower part of the housing from the joint. For the complete assembly and for fixing the position of the support and drive cylinders of the support elements and of the transmission elements in the housing, the other part of the housing is simply placed ^ ie, the upper part. The lower part of the housing is used in assembly as mounting aid. No auxiliary devices are necessary for securing any part in the corresponding housing or the like. A construction system of two covers of the casing, with the separation along a joint, through said openings, also allows, in a particularly simple way, to create bearing seats insensitive to the tolerances for the supporting elements . The corresponding bearing seats have been configured in both parts of the housing. In this way, a bearing seat is always limited on the one hand to the upper part of the housing and on the other hand, on the other side of the housing. In this way it is possible to fasten the corresponding support elements between the upper and lower part, without it being necessary to manufacture the necessary bearing seats with excessive precision. The possibility of manufacturing with tolerances not too narrow is created, which is economically more advantageous than a production with very small tolerances. This allows cost advantages.

The recess or the bearing seat formed by a cup-like recess, having an opening through the joint, can be present. In other words, the opening of the recess is in a surface that forms the joint, from which the recess extends to the wall of the housing. The housing parts in this manner are essentially free of undercut and can be manufactured from simple and inexpensive injection parts. A simple housing shape is maintained if the joint is located, at least in sections, in a plane that is aligned parallel, both to the axis of rotation of the first actuating cylinder and also parallel to the axis of rotation of the second cylinder. drive. This section is found in the casing cylinders, especially in this area. It is also possible to configure the flat gasket as a whole, which further simplifies the casing molds. The support elements housed by the parts of the housing can be protected outwardly by means of gaskets which act against fouling. In addition, these sealing devices prevent wear, dust or lubrication means from leaving the housing towards the outside, and to penetrate the dust and dirt from the outside into the housing. The housing with the aforementioned configuration can be easily manufactured from plastic, especially as an injected part. The precision of the housing parts ñ injected is sufficient for the intended purpose, so that these parts, thanks to their provision of the joint in the area of the support elements can be used without reworking work. The supporting devices for holding the support elements are preferably provided in the recesses provided in the housing parts, in which the support means with the closed housing have been fastened. In order to achieve not only a radial fixation of the support elements, but also with reduced clamping forces, recesses are preferably configured as a housing. These represent side walls, which fix the support elements in both axial directions. The housings are accessible, however, from the joint, in such a way that the support elements, when assembling the device can be simply placed in the housings. The recesses of the housing parts are preferably configured differently. While the recesses of one half of the housing house, without play, the support elements and thereby determine their position, the recess of the other half of the housing can be configured in such a way that the support elements have a certain play. in the direction of the board. The depth of the corresponding recess or housing is, however, guided in such a way that the support element finds its seat in the recess. In this way, it is furthermore achieved that the support element finds a firm seat in the support device formed by the recesses disposed facing one another. However, it is also possible to join the parts of the housing with a certain tolerance. They must be positioned exactly, in relation to each other, in such a way that adjustment pins or other comparable adjustment elements are not required. The fastening of the support elements is particularly insensitive with respect to production tolerances and thus with respect to the fastening of the support elements. These hold the support elements without play in the housing. The elastic elements can be configured as one-piece sections of the housing part. One embodiment, in which the assembly, that is to say the assembly of the device can be carried out in a particularly simple manner, has a housing, which is configured in such a way that the support cylinders and the transmission means are fixed between them in a single part of the casing in relation. This allows, in the assembly, place all the parts in a part of the housing and mount them in this way, whereby the device is completely assembled by the placement of the second part of the housing. The device can be configured in such a way that the support cylinders only go to one side of the housing. Several spools of yarn can be simultaneously housed and unwound if the support cylinders exit from both sides of the housing. The support cylinder can be configured as a single piece as well as several pieces. In the embodiment of several, the support cylinder has a central part, in which parts of the cylinder have been inserted on both sides and secured by means of fixing screws. In the realization of a single piece, a good concentric running of the support cylinders is achieved in a simple manner. This is important for the uniformity of the yarn supply. In another embodiment, the transition means fits between two bearings, in which the support cylinder is mounted. In this way a uniform load of the bearings is achieved, which allows a precise work of the device. The transmission element is preferably a combined transmission toothed belt-toothed belt. For this purpose, it is provided between a drive shaft, exiting with one end of the housing, and supporting a belt pulley at this end, and a conical wheel gear on a primary shaft rotatably supported in the housing. This has a conical wheel joined together with the drive shaft, which can engage with one of the two conical wheels fixed by screws of the primary shaft. The direction of rotation of the primary shaft is possible by selecting the gear that meshes with the conical wheel of the drive shaft. As a force transmission element, a belt is used between the primary shaft and the first of the support cylinders on the primary shaft. A belt, a toothed belt, a flat belt or the like can be used as a belt. If belts are used, especially toothed belts, no tensioning means are necessary to maintain the tension of the belt. A toothed belt is advantageous, which works without slippage, in such a way that the first bearing cylinder has a defined number of revolutions. A second toothed belt can be used as a force transmitting means between the first support cylinder and the second support cylinder. With respect to an embodiment with only one toothed belt, which runs above the primary axis, the belt running through the first and second support roller has an advantage that higher angles of hugging are achieved, such that with tension With a reduced belt, there is no fear of jumping and thus the unsynchronized running of the support cylinders. In addition, metal or plastic chains can be used for the drive. The connection of the housing parts to each other can, for example, be carried out with simple fastening elements by shape connection. These are bolt joints or also retaining joints. The retaining connections have the advantage that the assembly by a suitable design is particularly simple and that the retaining means can be formed in one piece with the parts of the housing. The retaining means may be retaining tabs or other retaining recesses provided in the housing, which fit into the recesses of the other part of the housing. The housing parts can also be joined together by bonding material, that is, by gluing or welding together, which results in robust housing designs. Centrifugal elements, such as switches or the like, can be provided in the yarn supplying device for the control of the bobbins or the running of the yarn. These sensors can be fastened in the rail provided in the housing, which is provided with fastening elements for the coils to be unwound. The sensors are connected by electrical conductors to an electrical connection device, which is arranged in a fixing device provided for fixing the housing in the frame of the machine. The electrical conductors are formed by metal straps placed in the housing, which, for example, are fixed by retaining stops in the housing. The metal strips extend through the joint, whereby in the joint the corresponding elastic contact elements are provided, which cause an electrical contact when placing the housing parts on top of each other. In one embodiment of the invention, an adjustable device is provided for axially fixing the coils on the support and drive rollers. This is preferably the rail mentioned above, fixed in a part of the casing, in which slides that can be set discretionally with a stop. The slide is fixed by a clamping screw, which can also be fixed during the operation of the wire supply device. An exemplary embodiment of the invention is shown in the drawing, in which: FIG. 1 is shown, a thread feeder device with a box divided into two pieces for elastomeric yarn for use in machines for knitting or knitting, in one piece perspective representation, figure 2, the wire feeder device according to figure 1 with the housing open, in schematic representation and simple perspective, figure 3, the wire feeder device according to figure 1, with a coil, in representation in schematic perspective, Figure 4, the axes and transmission elements housed in the housing of the wire feeder device according to Figure 1, as well as two bearing and drive cylinders used in the coils shown, in Figure 3.

Figure 1 shows a wire feeder device 1 for elastomeric yarns, but without coil to be unwound. The thread feeder device 1 is provided for a machine for knitting or knitting, in which several wire feeder devices of the same type have been fixed. The yarn feeder devices 1 then each accommodate one or more spools and unwind them at a predetermined speed, so that the elastomer yarn is supplied to the knitting stitches with constant yarn tension. The wire feeder device 1 has, seen in plan, an L-shaped box, whose cross section is approximately square with rounded corners. In the shorter L-shaped housing 3, an insert 5 is formed with a clamp 6 for attachment to a machine frame (not shown). Casing 3 is split by a gasket &; and has a lower part of the housing 10 and an upper part of the housing 11, each of which is formed as a piece of plastic injected in one piece. The seal fi is in a plane, which cuts the housing 3 approximately in half. If necessary, at least one housing part 10 can be provided with a sealing element, for example a joint formed in one piece. On each side of the box 3 two support cylinders 13, 14 emerge; 13 ', 14', kept separate and parallel, which are used for the accommodation and operation of the coils to be unwound (figure 3). A yarn spool of this type is placed in such a manner, with its peripheral surface in the horizontal use position and with the support cylinders 13, 14; 13 ', 14' rotating on each axis of rotation 12, 12 ', that with a rotation of the support rollers 13, 14; 13 '14' rotates on its own coil axis. The distance between the support cylinders 13, 14 is smaller than the outer diameter of a coil body carrying the coil. This also applies to the support cylinders 13 ', 14'. Parallel to the support cylinders 13, 14; 13 '14', but separated from these, a rail 15, which is supported by a support 17 from the housing part 10, is arranged in the service position below the housing 3 and as shown in FIG. 3, it is used to carry a coil limiter 19. This coil limiter has a slidable slide on the rail 15 and can be locked by means of a clamping screw configured, for example, as a knurled screw 20, from which it exits upwards. imitably perpendicular to the rail 15 a limiting barrier, to such an extent that it maintains in its axial direction a coil disposed on the support cylinders 13, 14. A corresponding slider is fixed to the section disposed below the support cylinders 13 ', 14 ' The coil limiter 19 allows a simple adaptation to the different widths and numbers of coils. The support cylinders 13, 14; 13 '14' pass through an inner enclosure 23 limited by the housing and visible, for example, in FIG. 2, in which transmission means for driving the support cylinders 13, 14 have been arranged. The transmission means 25 they join, for example, a drive wheel 27 visible, for example, in FIG. 1, with the support cylinders 13, 14; 13 '»14. The drive wheel 27 is mounted by an axle in the vertical use position, that is to say perpendicular to the support rollers 13, 14; 13 '14' and driven by rotating drive belts, provided on top of the machine for knitting or knitting. The driving means 25, which are used for the transmission of force from the drive wheel 27 to the support rollers 13, 14, as well as the support of the support rollers 13, 14; 13 '14' in the housing 3, can be seen in figure 2. On the short side of the internal enclosure 23 configured as L-shaped housing 3, a rotating primary shaft 29 is mounted, which carries a conical wheel 31. This is found as shown in Figure 4, meshed with a conical wheel 32, which in turn is mounted in a fixed manner on the shaft driven by the drive wheel 27. At both ends has been mounted the rotating shaft 29 by means of ball bearings 34, 35, housed in ecstasies 36a, 36b of the housing or of the part of the housing 10, 11 which is explained below that form the holding devices for the bearings On the long side of the box 3, other housings 36c, 36d as well as 36e, 36f are provided to receive the ball bearings 41, 42, 43, 44. The notches 36c, 36d are arranged in such a way that they provide a shaft 4-6 which supports the support cylinders 13, 13 'on each side (FIG. The axis 46 and the support cylinders 13, 13' are arranged parallel to the axis 29. The axis it supports a pulley for toothed belt 4 -fi, which is driven by a toothed belt 50 by a toothed belt pulley 52 mounted on the shaft 29. Similarly, an axle is mounted on the bearings 43, 44- 54-, which on the end sides carries the support rollers and lß drive 14, 14 '. The shaft 54 is provided with a toothed belt pulley 55, which is driven by a toothed belt 57 by the toothed belt pulley 4-6 mounted on the shaft 46. As shown for a greater simplicity not in Figure 2, but only in figure 4, another conical wheel 56 can be provided in the shaft 29, which allows an inversion of the direction of rotation of the axis 29. For this purpose, the conical wheels 31, 56 have been arranged displaceable on the shaft 29 and made to engage further with the conical wheel 32. The recesses 36a to 36f provided in the parts of the housing 10, 11 for receiving the ball bearings 34, 35, 41, 43, 44 uniformly with the only difference that the housing 3 in the recesses 36c to 36f it is open to the outside, and otherwise closed. Representing all the recesses, a recess designated 36 is shown in FIG. 5, which is formed in the corresponding wall of the housing parts 10, 11. In the lower part of the housing 10 it is arranged starting from the seal 6 a housing 61, whose radius corresponds to the outer radius of the bearing to be accommodated in the housing 61, for which the ball bearing 4-1 has been represented by way of example. The width of the recess, measured transversely to the wall, corresponds to the width of the ball bearing 41 measured in its axial direction. Laterally, that is to say, referred to the ball bearing 41 in axial direction, the limited housing 61 is formed by the flat-shaped faces 63, 64, arranged parallel to each other, which cover the ball bearing 41 up to the inner ring opening. In the upper part of the housing 11, a corresponding housing 66 is formed and arranged in such a way that it encloses the housing 3 without steps in the housing bag 61. The housing 3 contains, as shown in FIGS. 6 and 7, 69, 70 for a connection between the sensors or switches provided in the feeder device 1 and the electrical connection elements 72 arranged in the jaw area 6. The conductor 70 is connected to ground and to the rail 15. The conductor 69 goes from terminal 6 to a connection for disconnect switch not shown. Both the conductor 69 and the conductor 70 are formed by metal strips, which have been placed in the casing 3 and are held by projections 74 formed integrally in the parts of the casing 10 and 11. The conductors 69, 70 they are guided through the seal 6, the metal strips forming the conductors 69, 70 are interrupted by the seal 6, and end in elastic tongues 76 and 77. The elastic tongues 76 and 77 are elastically pre-stressed and thus ensure a closure electrical contact. To contact, no welding work is necessary. The connection of the conductors 69, 70 in the corresponding conductors of the knitting machine or knitting machine is carried out in the jaw area 6 by means of plug or terminal connections, without special measures when the feeding device 1 is fixed on the machine of knitted or knitted fabric. The device described up to this point functions in the following way: The feeder device 1 is installed by means of the clamp in a frame of a knitting machine or knitting machine. A toothed belt, which drives several feeder devices of the same type 1, is placed on the drive pulley 27. On the support cylinders 13, 14, 13 ', 14-' coils are placed, indicated in figure 3, with the yarn to be unwound . In driving the drive pulley 27 by the toothed belt, but not shown, the transmission element 26 transmits the movement directed to the support cylinders 13, 14, 13 ', 14', in such a way that a thread 60 You can unroll with a speed and the precise direction. The assembly of the feeder device 1, starting from the different loose components, is as follows: In the part of the lower housing 10, as shown in FIG. 2, the transmission elements 25 and ball bearings 34- are placed, 35, 41, 42, 43, 4-4, after which it is placed in the housing part 11 is secured in the housing part 10. For these, screws or retraction means (not shown) can be used. In detail, the shaft 29 is provided with a conical wheel 31 and the toothed belt pulley 52, the toothed belt 50 is placed on the toothed belt pulley 52 and the shaft 29 with its ball performances 34, 35, and placed in the recesses 36a, 36b. Next, the shaft 46 is provided with the pulley for mounting the ball bearings 41, 42 and placing the toothed belt 50, 57 the ball bearings 41, 42 are placed in the recesses 36c, 36d. The support cylinders 14, 14 'are suitably mounted. The whole process can be carried out without auxiliary means and without special tools. It is simple and can be done by untrained personnel. When the upper part of the housing 11 is installed, the wire feeder device 1 is assembled. The parts of the housing 10, 11 are injection parts, which have all the necessary fixing devices for accommodating the same with them. pieces to be joined, as projections formed in a single piece or recesses provided therein. In particular, the recesses 36 are formed in such a way that they can accommodate the ball bearings, without grinding work, and that the ball bearings when mounting the parts of the housing 10 and 11 are held firmly. For this, in addition to the described housings 61, 66 alternative bearing seats 64a, 64d are provided, which are shown in figures 6 to 12. In the embodiment shown in the figure &; all the bearing seats 694a are set equal, instead of the structures 36a to 36b of the housing. In the part of the housing 10, a bag 65 is provided, whose depth coincides with the diameter of the bag bearing 41, which is drawn in this case in representation for all bag bearings to be placed. On the bottom side, the half-round housing bag 65 has been configured, so that the bag bearing 41 is free of play on the bag 65. Axially the bag 65 is unlimited by other faces not shown, which maintain the bearing of bags 41 in the axial direction without appreciable clearance. The housing part 11 is formed in the flat gasket 6 and has no cut-out. It maintains the bag bearing 41 in the bag 65. However, it has been configured as all embodiments of the bearing seat 64a (, bae) between the housing parts 10, 11. The advantage of the above embodiment resides in the ease of assembly. The bag bearings are fixed laterally after being placed in the corresponding bag 65, so that the assembly is also easily carried out, if the toothed belts 50, 57 must be tensioned (FIG. 2). The bearing seat 64a is also manifestly insensitive to inaccurate assembly of the parts of the carcass 10, 11 in relation to one another. The allocation of the housing parts 10, 11 is not important for the bearing seat 64a. The seal 6 limits the bearing seat 64a on one side and also forms its closure.

In Figure 9 another embodiment of a bearing seat 64b is shown. In this embodiment, notches or pouches 66, 67 are provided both in the part of the upper case 11 and also in the part of the lower case 10. The pouch 66 of the lower part of the case 10 is shaped This is illustrated by the fact that the radius of the bag bearing 41, represented here again in representation of the others, slightly changes the radius of the outer ring. The bag 67 provided in the upper part of the housing 11 has a flat bottom 66, which rests on the outer ring of the ball bearing 41. The separation from the bottom 66 to the deepest point of the housing 66 corresponds to the outer diameter of the bearing balls 41. The recesses or housings 66, 67, which in all the bearing seats again have side faces, limit the seal 6, which passes through the center of the ball bearing 41. In this bearing seat 64b a displacement is possible. of the parts of the housing 10, 11 relative to one another, without affecting the bearing seat 41. In this way, production tolerances can be compensated. In FIG. 10, another bearing seat 64c is shown, which allows a resilient bearing of the ball bearing 41 and thus ensures a greater insensitivity to the tolerance. In the housing part 10, a housing bag 91 is formed which differs from the recesses and pockets described above of the housing part 10 because it houses the ball bearing as a prism. For this purpose, it has accommodation pockets 91 with two bearing surfaces 93, 94, essentially at right angles to one another, which are formed flat, in which the outer ring of the bearing is located in line. A housing bag 95 provided on the upper part of the housing 11 has a flat, but elastically shaped bottom on which the ball bearing 41 rests. The bottom 96 is elastically deformed by the ball bearing 41. The bearing of balls 41 the bearing seat 64c is housed in three points. The bottom 96, formed elastic, guarantees a secure seating of the ball bearing 41 also with large tolerances. The elastic flexibility of the bottom 96 can be maintained by means of a corresponding lenticular notch 97, which is disposed at a small distance from the bottom 96 in the housing part 11. If necessary, an elastic element 96 can be provided in the recess 97. Figure 11 shows a modified embodiment of a bearing seat 64d. In the housing part 10, a housing bag 101 is formed, which houses the ball bearing 41 as a prism. For this purpose, the housing bag 101 has two abutment surfaces 103, 104, which are essentially at right angles to each other, in which the outer ring of the bearing rests at two points. Due to the bulging of the bearing surfaces 93, 94, the ball bearing 41 rests on the bearing surface 93c with somewhat larger areas. A housing bag 105 provided in the housing part 11 has a pumped bottom 106, on which the outer ring of the ball bearing 41 abuts. The ball bearing 41 is housed in the bearing seat 64d at three points. The radius of curvature of the bottom 106 projects beyond the diameter of the outer ring of the ball bearing 41 clearly. In this way an insensitivity to tolerance is achieved. Finally, FIG. 12 shows a bearing seat 64e which resembles the bearing seat according to FIG. 9. A recess 107 provided in the housing part 10, however, has a larger external diameter of the recess 66. that of the exemplary embodiment according to FIG. 9. A recess 106 is provided in the housing 11, which has a greater depth than the recess 67. The ball bearing 41 in the bearing seat 64e is supported by a ring toric 111 in the notches 107, 106. The O-ring 11 forms an elastic element, which holds the ball bearing 41 in the bearing seat 64e largely compensating the manufacturer's tolerances. The O-ring fits into a groove of the recess 107, provided if necessary in the bottom, not shown. A toric ring can also be provided in all other previously described embodiments of the feeder device 1 as an elastic or compensation element. The diameters and depths of the corresponding bearing seats 46a to 64e will be properly determined. Disregarding the embodiment described above, both the support cylinders 13, 13 'and also the one-piece support cylinders 14, 14' can be configured. In this way it is also possible to configure the support cylinders 13, 13 '; 14, 14 'in one piece with the pulleys for toothed belt 46, 55. This achieves a good concentric running, easy assembly and reduced manufacturing costs. In addition, embodiments are possible in which the housing part is combined according to FIGS. 9 to 12, with any other part of the housing of FIGS. 4 to 12. A feeder device for supplying elastomeric yarns in the machines for generating goods. knitted or knitted has a split shell, in which the supporting cylinders have been mounted rotatable, parallel and separated. The housing encloses an interior enclosure, which houses the transmission elements for the actuation of at least one of the support cylinders. The transmission elements transmit the force from a drive wheel, which is fixed to a shaft that leaves the housing in at least one support cylinder. The support cylinders are mounted by ball bearings, which are held by the seats of the bearings provided in the housing. The seats of the bearings have been formed in the parts of the housing configured in one piece, which are preferably manufactured runs through all the seats of the bearings, in such a way that the ball bearings are clamped between the parts of the Case. The ball bearings are also fixed by fixing the housing parts together.
