Abstract

The invention relates to a spacer knitted fabric which is preferably produced by a circular knitting machine and comprises two material webs connected by spacer threads (21a, 21b). One of the two material webs contains a base knitted fabric that is produced with only one ground thread (19), while the other material web contains a base knitted fabric which is produced from one ground thread (11) and is additionally provided with at least one plating thread (12) in at least selected rows of stitches (1, 4). According to the invention, said plating thread is inserted in selected stitches (15) of these rows of stitches (1, 4) in addition to the ground thread (11) and floats therebetween. The invention further relates to a method and a knitting machine for producing such a spacer knitted fabric.

Description

Spacer knit and method and knitting machine for its production

The invention relates to a spacer fabric according to the preamble of claim 1 and a method and a knitting machine for its production according to the preambles of claims 8 and 12.

Spacer knits, which consist of two interconnected by a spacer thread webs are used for example for the production of sports clothing pieces such as training or warm-keeping suits and inserts for the sole or sidewall area of shoes (eg DE 74 25 934 Ul, DE 28 50 823 Al). It is therefore u. a. it is desirable to provide such spacer knitwear with cross-directional extensibility and elasticity depending on the particular case, thereby increasing the wearing comfort.

In order to influence the extensibility of right / left knitted fabrics, it is known in particular in connection with plush fabrics (eg DE 39 27 815 C2, DE 197 07 053 A1) to incorporate at least one additional floats or plating yarn into selected courses of a basic knit partly processed into meshes and partly to loops. Spacer knits, however, are not produced on plush machines, but generally on circular knitting machines (eg DE 103 20 533 A1), wherein one web is knitted with the needles of a needle cylinder and the other web with the needles of a dial. Knitting machines of this type, if the needles of the cylinder and the dial are gap, also referred to as fine ribbing machines, at least if they have smaller needle pitches and large diameter of z. A disadvantage of such knitting machines is that the two webs must each be made with all the needles of one or the other needle bed, which is why the transverse elasticity and transverse strain and other properties only by the choice of the yarn used and only in small limits can be changed.

Proceeding from this, the technical problem underlying the invention is to provide a spacer fabric of the type described at the outset whose properties are changed within wide limits, in particular with regard to elasticity and extensibility can be. In addition, a method and a knitting machine for producing such a spacer knit are to be proposed.

To solve this problem, the characterizing features of claims 1, 8 and 12 are proposed according to the invention.

The invention has the advantage that the properties of the web produced on the needles of a needle bed, and thus also the spacing knitted fabric as a whole, can be influenced considerably more than hitherto by the choice and type of integration of the plating thread. The application of a little stretchy thread material such. B. Polyester has in connection with z. B. in the knitting 1: 1 incorporated floats result in that in the transverse direction (course direction) very little stretchable goods is obtained. By contrast, the use of an elastomer thread as a plating thread leads to a very flexible product. Therefore, by the number and arrangement of the floats in the web produced with the needles of a needle bed in conjunction with suitable yarn qualities either a very stable and abrasion-resistant or a largely elastic or at least partially embossed by floats goods can be generated. With regard to the knitting machine proposed according to the invention, there is also the advantage that comparatively minor structural changes of known knitting machines are sufficient to produce the new spacer knitted fabric, and no complete redesign is required. This is especially true for the particularly preferred application of a circular knitting machine.

Further advantageous features of the invention will become apparent from the dependent claims.

The invention will be explained in more detail below in connection with the accompanying drawings of an embodiment. Show it:

Fig. 1 shows schematically the structure of a erfϊndungsgemäßen spacer knitted fabric; 2 shows a schematic radial section through the essential parts of the invention for a circular knitting machine for producing a spacer knitted fabric;

3 shows the interior view of a lock of a first needle bed of a knitting machine according to the invention; and

4a and 4b schematically show the needles and the lock tracks of six successive knitting systems of a knitting machine according to the invention for producing the spacer knitted fabric according to FIG. 1.

Fig. 1 shows schematically six courses 1 to 6 of a spacer knitted fabric according to the invention. In all courses 1 to 6 indicate in the upper area drawn, long and short dashes 7 and 8 respectively the needles of a first needle bed, z. As a dial, as well as in the lower area drawn, long and short dashes 9, 10 respectively the needles of a second, the first needle bed opposite needle bed, z. B. a needle cylinder, with the Rippnadeln 7, 8 and the cylinder needles 9, 10 z. B. differ by the height or position of their feet. Incidentally, the Rippnadeln 7, 8 and cylinder needles 9, 10 on gap, d. H. they are offset from each other by half a needle pitch relative to each other.

1 shows that the rows of stitches 1 and 4 are formed with three threads each, with a main thread 11 shown in solid lines, a first plating thread 12 shown in dashed lines and a second plating thread 14 shown in phantom. The background thread 11 is at all times existing cylinder needles 9, 10 processed into a mesh 15 and 16 respectively. The first plating thread 12 is filled with every other, z. B. odd-numbered cylinder needle 9 incorporated into the mesh 15 and placed in between afloat, whereby first floats 17 arise. The second plating thread 14 is with all the rest, z. B. even-numbered cylinder needles 10 incorporated into the mesh 16 and placed between these fast, causing floats 18 arise. Overall, therefore, form the courses 1 and 4, a first web in the form of a smooth, with all cylinder needles 9, 10 basic knitted fabric, wherein the first plating thread 12 in selected stitches 15 and the second plating thread 14 in the remaining stitches 16 are each processed together with the main thread 11 into two-thread stitches and therebetween lies afloat. The Rippnadeln 7 and 8 remain in the courses 1 and 4 in a non-knitting position.

In the courses 2 and 5 is knitted with a ground yarn 19 alone on all Rippnadeln 7, 8, whereby stitches 20 arise. The courses 2 and 5 thus form a second web in the form of a smooth, with all Rippnadeln 7, 8 basic knitted fabric.

In the courses 3 and 6, spacer threads 21a and 21b are processed. The spacer threads 21a, 21b can in principle be processed in any manner known per se in spacer knits. In the embodiment, it is provided that the spacer threads 21a, 21b consistently connect to the first and the second fabric web in the manner of tuck stitches. The spacer thread 21a is for this purpose z. B. in the course 3 of the odd-numbered cylinder and Rippnadeln 7 and 9 each processed to a tearing mesh 22, 23, while the spacer thread 21 b in the course 6 z. B. only from the even cylinder and Rippnadeln 8 and 10 each as a tether mesh 24, 25 is involved.

A complete section of the spacer knit thus consists of six courses, followed by further sections with similarly formed courses 1 to 6 follow. However, the order in which the various courses follow each other is largely changeable. For example, the first course can be formed with the Rippnadeln and the second course with the cylinder needles (eg DE 74 25 934 Ul). Furthermore, it is possible to provide more than two rows of base threads 1, 2 or 4, 5 between the stitch rows formed with the spacer threads 21a, 21b (eg DE 28 50 823 A1). In addition, it would be possible to form the tuck stitches 24, 25 in the stitch row 6 with the same needles as in the stitch row 3, respectively. For the purposes of the invention, it is important that selected courses (here 1 and 4) of the first web contain at least one first plating thread 12 or 14 inserted in addition to a first thread 11, which together with the first thread 11 results in two-thread stitches 9 or 10 and floats 17 or 18 is processed. As a result, as already mentioned above, both the character and the properties, in particular the elastic properties of the spacer knitted fabric, can be chosen largely as desired. In a hitherto considered best exemplary embodiment, two additional Plattierfäden 12, 14 in the knitting 1: 1 inserted for this purpose according to FIG. Alternatively, it would also be possible, instead of the l: l pattern another pattern, z. 1: 2, 2: 2, 1: 3 or the like, or the first plating thread 12 into the cylinder needles 1, 2, 5, 6, etc., and the second plating thread 14 into the cylinder needles 3, 4 , 7, 8 ... insert. The structure patterns that can be produced in this way are manifold and can be selected depending on the requirements made in the individual case.

The spacer fabric described with reference to FIG. 1 is preferably produced on a circular-edge knitting machine, in particular a so-called fine-ribbed machine, the most important components of which are illustrated schematically in FIGS. 2 to 4.

According to Fig. 2, a conventional circular knitting machine includes a first needle bed in the form of a needle cylinder 31, which is preferably rotatably mounted about a machine axis and provided at its periphery with conventional, parallel to the machine axis webs 32. These form between them grooves in which cylinder needles 33, preferably conventional cylinder needles, are mounted displaceably in the vertical direction. A cylinder lock 34 surrounding the needle cylinder 31 points to a knitting system u shown in FIG. a. Lock parts 35, the more detail below lays Schlossbahnen form, in which feet 36 of the cylinder needles 33 are guided in order to give them the usual ejection and withdrawal movements. r

Above the needle cylinder 31 is a standing opposite this, the second needle bed arranged in the form of a dial plate 37, which is preferably rotatable together with the needle cylinder 31 about the machine axis and on its upper side usual, arranged perpendicular to the machine axis webs 38 has. These form between them grooves, in which rib needles 39, preferably conventional latch needles, are mounted displaceably in the radial direction. The Rippnadeln 39 and the cylinder needles 33 are offset relative to each other in the circumferential direction of the needle cylinder 31, preferably by half a needle pitch. Above the dial 37 a ripple lock 40 is arranged, which is provided on the knitting system shown in FIG. 2, inter alia, with lock parts 41, which form further below explained lock tracks, in which feet 42 of the Rippnadeln 39 are guided to these the usual Austriebs- and deduction movements.

Finally, the knitting system according to FIG. 2 is associated with a thread guide 44 fastened to a holder 43, in order to supply the cylinder and ripple needles 33, 39 with the threads required for stitch formation.

Incidentally, it is clear that along the circumference of the needle cylinder 31 and the surface of the dial 37, a plurality of the described or similar knitting systems may be arranged, each of which required for expulsion and withdrawal of the cylinder and Rippnadeln 33, 39 lock parts 35 and 41st and thread guides 44.

Circular knitting machines of the type described are the expert u. a. From the above-mentioned documents (in particular DE 103 20 533 Al) generally known, which is why there is no need for further explanation here. However, it is clear that in the embodiment of the needle cylinder 31 are representative of any arbitrary per se, first needle bed and the dial 37 representative of a standing opposite this, also known per se, second needle bed.

3, 4a and 4b show an inventive design of the needles (here der- and Rippnadeln) of a first and second needle bed and the associated locks (here cylinder and Rippschlösser).

1, the grooves of the Nadelzy Linders 31 shown in FIG. 3 alternately (1: 1) with cylinder needles 46 and 47 are occupied, which have arranged at different locations feet. The cylinder needles 46 have a lower foot 48 and an upper (high) foot 49, while the cylinder needles 47 also have the lower foot 48 but a middle (deep) foot 50 interposed between the lower foot 48 and the upper foot 49 of the cylinder needles 46 is arranged. Similarly, the grooves of the dial 37 of FIG. 4a are provided with rib needles 51a, 51b each having a lower leg 52 and alternately a middle leg 53a and an upper leg 53b.

A cylinder lock 50 (FIG. 3) for a knitting system A (FIG. 4a) suitable for producing the courses 1 and 4 is provided with lock parts 55 to 58 according to the invention, which form three lock tracks for the three feet 48, 49 and 50. The cylinder lock 54 designed in this way replaces the known cylinder lock 34 shown in FIG. 2 according to the invention.

A lock track formed by the lock member 58 for the feet 49 of the cylinder needles 46 includes, as particularly Fig. 4a shows, a rising portion 59a, which leads to a knitting position (position II in Fig. 4a), upon reaching one in the hook of any cylinder needle 46 mesh has slid over the tongue on the shaft of the cylinder needle 46. Further expulsion of the cylinder needles 46 is prevented by the lower leg 48, which cooperates with a lower edge of the lock member 56.

The section 59a is adjoined by a section 60a, through which the cylinder needle 46 is first withdrawn to such an extent that, approximately in a position Gl-Gl (FIG. 4a), a base thread supplied by a thread guide 61 and corresponding to the background thread 11 according to FIG in the cylinder needle 46 and the hook is inserted. The section 60a is adjoined by a section 62 along which the cylinder needles 46 are not further lowered so that they can receive a plating thread corresponding to the first plating thread 12 (FIG. 1) in a position Pl-Pl (FIG. which is supplied by a schematically indicated yarn guide 63. The foot 49 then passes under the guidance of the foot 48 and the lock member 56 into a channel 64 (Fig. 3) which is incorporated in the lock member 58, and is guided by this, that it at another, in motion or knitting direction v following thread guide 65 receives no thread by the cylinder needle 46, for example, sufficiently deep pulled back before passing this thread guide 65. Finally, the foot 49 of the cylinder needle 46 reaches a portion 66a of its associated track, along which the cylinder needle 46 is withdrawn to a deep, the tee position corresponding position H-II, to form a mesh with the picked ground yarn and the first plating yarn , The guide along the section 66a is preferably carried out with the aid of a trigger part 67 connected to or following the lock part 56 (FIG. 3). This process is repeated for all cylinder needles 46.

The lock groove 57 formed by the lock member 57 associated with the feet 50 of the cylinder needles 47 corresponds except for a punctured in Fig. 4a indicated area of the above for the feet 49 of the cylinder needles 46 Schlossbahn, especially with regard to their sections 59b, 60b and 66b. For better understanding, however, the cam track for the feet 50 in FIG. 4a is shown substantially lower than this is actually the case. Since the cylinder needles 46 and 47 in Nadelzy cylinder 31 each side by side and not, as shown in Fig. 4a, are arranged below each other, the lower castle track is actually separated only by a distance from the upper castle track, the distance of the feet 49 and 50 corresponds to each other. In addition, the three yarn guides 61, 63 and 65 are again shown in Fig. 4a in the region of the lower castle track. It can be seen that the lock track for the legs 50 differs from that for the legs 49 substantially only in that it has a section 68 and a section 69 following in the direction of knitting v. The portion 68 serves the purpose of the cylinder needles 47 after the Recording of the basic thread from the yarn guide 61 deducted so deep into an intermediate position that it does not receive the first plating thread presented by this when passing the thread guide 63, her hook but still remains open. In contrast, the section 69 has the task of expelling the foot 50 and thus the cylinder needle 47 again so high that they in passing the thread guide 65 receives the supplied by this, the plating thread 14 in Fig. 1 corresponding plating thread in addition to the main thread (position P2- P2- in Fig. 4a). For safe guidance of the cylinder needles 47 in this area, the sections 68, 69 are preferably realized according to Fig. 3 by a formed in the lock part 57 channel 70, in which the feet 50 are guided by means of the lock member 56 and the lower feet 48, which also are present at the cylinder needles 47.

Overall, it thus follows from FIGS. 3 and 4 a that the ground yarn in the knitting system A is fed to all the cylinder needles 46 and 47, while the first plating yarn is inserted only into the cylinder needles 46 and the second plating yarn is inserted only into the cylinder needles 47. which corresponds to the 1: 1 distribution of FIG.

The lock of the second needle bed, in the exemplary embodiment thus the Rippschloss 40 (Fig. 2), has for the feet 53a and 53b shown in Fig. 4a of the Rippnadeln 51a, 51b in the knitting system A only one lock track 71a and 71b, the one Not knitting the Rippnadeln 51 a, 51 b corresponds, so that they remain idle in the system A.

In the knitting system A thus the course row 1 according to FIG. 1 is formed.

In the knitting system B of FIG. 4 a, the ripple lock is provided with customary ejection sections 72 a and 72 b leading into a knitting position and subsequent withdrawal sections 73 a, 73 b leading into the knock-off position, analogous to FIG. 3 on the feet 52 and 53 a. 53b act. Thereby, all the rib needles 51a, 51b on the knitting system B are selected for knitting so as to be one of a

Thread guide 74 supplied, the basic thread 19 of FIG. 1 corresponding Grundfa- pick up (position G2-G2) and process into stitches.

Incidentally, as with the cylinder lock for the system A, that the Rippnadeln 51a, 51b actually with the same radial distance from the machine axis side by side in the dial and not, as shown in Fig. 4a for clarity, are arranged one behind the other, which is why the two Schlossbahnen have a distance corresponding to the distance of the feet 53a, 53b from each other.

The cylinder lock has in the knitting system B only one track section 75a, 75b for the feet 49, 50, which essentially corresponds to a non-knitting position for the cylinder needles 46, 47, so that they remain inactive in the system B. This results in the knitting system B, the row of stitches 2 of FIG. 1st

In the knitting system C of FIG. 4a, at a position AF1-AF1, a spacer thread corresponding to the spacing thread 21a according to FIG. 1 is fed by means of a thread guide 76. For this purpose, the cylinder lock on a each with a Austriebs- and deduction section 77, 78 provided Castle track, which is assigned to the feet 49 of the cylinder needles 46 alone. The expulsion section 77 leads into a catching position, so that the spacer thread 21a according to FIG. 1 is supplied to only every second cylinder needle (that is to say here the cylinder needles 46) in the catching position.

The same applies to the Rippschloss. This has in the knitting system C, each with a Austriebs- and deduction section 79, 80 provided castle track, which is associated solely with the feet 53a of the Rippnadeln 51a, so that only they receive the supplied from the yarn guide 76 spacer thread in fishing position. This results in the knitting system C, the row of stitches 3 of FIG. 1st

According to Fig. 4b corresponds to the formation of the cylinder and Rippschlosses in the knitting system D of the system A and in the knitting system E of the system B, so that a re-description is not required. Thus, in the knitting system D the course of stitches 4 and in the knitting system E the course of stitches 5 of the spacer knitted fabric according to FIG. 1 are formed. In the sixth knitting system F, a spacer thread 21b according to FIG. 1 corresponding spacer thread is fed by means of a thread guide 81 (position AF2-AF2). In contrast to the knitting system C, the cylinder lock here has a lock track provided with a respective expulsion and withdrawal section 82, 83, which acts solely on the feet 50 of the cylinder needles 47, with the expulsion section 82 leading into the catching position. Accordingly, the Rippschloss in the knitting system F a leading into the catching position Austriebsabschnitt 84 and a take-off section 85, which are associated solely with the feet 53b of the Rippnadeln 51b. This results in the knitting system F, the row of stitches 6 of the spacer fabric of FIG. 1st

As an alternative to the described procedure, it would be possible to insert the spacer thread in the knitting system 6 in the same way as in the knitting system 3. In this case, the spacer fabric would consist of a plurality of sections, which are formed from the three courses 1 to 3 of FIG.

In principle, all yarns customary in knitting technology can be used as base and plating threads. If z. B. a polyester yarn used for both the main thread as well as for the Plattierfäden, then there is a spacer fabric, which is a web in the transverse direction very little stretchy and their extensibility z. B. is only one-tenth of what is achievable with a standard Rippware. In contrast, z. B. Elastomerraden used as Plattierfäden, especially in combination with a basic thread of cotton, then results in a transverse direction particularly elastic web. As a result, in contrast to conventional spacer knits, in which a plating thread can possibly be supplied in addition to the basic thread all cylinder or Rippnadeln produce goods with a completely new character. By choosing in particular the elastic properties and / or the number and the arrangement of the floats also numerous levels of elasticity can be realized.

The invention is not limited to the described embodiment, which can be modified in many ways. This applies initially in terms of Use of two plating threads 12 and 14. It would be possible, for example, to omit one of the two plating threads. In this case, z. For example, one of the thread guides (eg 65) is missing and the track section 69 is omitted. Apart from that, the selection means by means of which the cylinder needles 46, 47 for receiving the first or second plating threads 12, 14 and the cylinder and dial needles for receiving the spacer threads 21a, 21b are selected are largely arbitrary. In principle, all agents can be used, as are well known in particular for the production of Jacquard patterns. Instead of the 1: 1 selection shown in FIG. 2, a selection in the sense of a 1: 2, 2: 2, 1: 3 pattern or the like for the plating threads 12, 14 could alternatively be made, for example in the Nadelzylindernuten after a cylinder needle 46 each two or three cylinder needles 47 are used (or vice versa). Corresponding selection possibilities are found in knitting machines with electromagnetic or electrical selection means for the needles. It would also be conceivable to produce the webs consisting of the ground threads 11 and 19 not with all, but only with selected cylinder and / or Rippnadeln, so that already result from flooding patterns. Further, instead of latch needles any other known in knitting technology needles, in particular z. B. pusher (compound) or tip needles are used, the term "insertion of threads in the needles" that technique is understood, which is required in each case to process the supplied threads by means of existing in individual cases knitting tools to mesh. In addition, it is clear that instead of the described circular knitting machine, other knitting machines with two opposing needle beds can be used for producing the spacer knits according to the invention, for example flat knitting machines, double cylinder machines, interlock machines (analog needle selection provided) or circular knitting machines with stationary needle cylinders and dials and revolving locks. It would also be conceivable to make the courses 1 and 4 of FIG. 1 with appropriate design of the various components with the dial and the courses 2 and 5 with the needle cylinder. Finally, it is understood that the various features also in combinations other than those described and illustrated can be applied.
