Abstract

A spacer fabric with two fabric webs connected by spacer threads (21a, 21b), preferably produced on a circular knitting machine, is described. One of the two webs contains a basic knitted fabric produced only with one basic thread (19), while the other fabric comprises a basic knit fabric made of a main thread (11), which at least in selected rows of stitches (1, 4) additionally provided with at least one plating thread (12) is that in selected stitches (15) of these rows of stitches (1, 4) in addition to the main thread (11) is inserted and in between is afloat. In addition, a method and a knitting machine for producing such a spacer knitted fabric are described (FIG. 1).

Description

  • The 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 12th
  • Spacer fabrics consisting of two webs interconnected by a spacer thread are used, for example, for the production of sportswear such as training or warm-keeping suits, as well as inserts for the sole or sidewall region of shoes (e.g. DE 74 25 934 U1 . DE 28 50 823 A1 ). It is therefore desirable, inter alia, to give such spacer knitwear a cross-directional extensibility and elasticity dependent on the individual case, in order to thereby increase the wearing comfort.
  • In order to influence the extensibility of right / left knitted fabrics, it is known in particular in connection with plush sheets (eg DE 39 27 815 C2 . DE 197 07 053 A1 ) to incorporate into selected courses of a base knit at least one additional floats or plating yarn, which is partially processed into stitches and partly to floats. However, spacer knits 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 smaller needle pitches and large diameters of z. B. 26 '' and more. A disadvantage of such knitting machines is that the two webs must 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 can only be changed by the choice of yarn used and only in small limits.
  • outgoing thereof, the invention is based on the technical problem, a spacer fabric of the Initially designated genus to create its properties especially with regard to elasticity and elasticity can be changed within wide limits. Furthermore intended to provide a method and a knitting machine for making a such spacer knits are proposed.
  • to Solution to this problem according to the invention characterizing features of claims 1, 8 and 12 proposed.
  • The Invention has the advantage that the properties of on the needles of a needle bed produced web and so that the spacer knit as a whole by the election and the Type of integration of Plattierfadens much stronger can be influenced as yet. The application of a low stretchable thread material such. B. polyester has in connection with z. B. in the knitting 1: 1 incorporated floats As a result, one in the transverse direction (course direction) very low stretchable goods is obtained. The application of an elastomeric thread as a plating thread, however, leads to a very flexible Would. Therefore, by the number and the arrangement of the floats in the web produced with the needles of a needle bed Optionally, in conjunction with suitable yarn qualities very stable and abrasion-resistant or a largely elastic or an at least partially flooded goods be generated. With regard to the invention proposed Knitting machine also gives the advantage that comparatively minor structural changes known Knitting machines are sufficient to produce the new spacer knit to be able to, and no complete redesign required. This is especially true for the most preferred application a circular knitting machine.
  • Further advantageous features of the invention will become apparent from the dependent claims.
  • The The invention will be described below in conjunction with the accompanying drawings explained in more detail in one embodiment. Show it:
  • 1 schematically the structure of a spacer knitted fabric according to the invention;
  • 2 a schematic radial section through the essential parts of the invention for a circular knitting machine for producing a spacer knitted fabric;
  • 3 the inside view of a lock of a first needle bed of a knitting machine according to the invention; and
  • 4a and 4b schematically the needles and the castle tracks of six consecutive knitting systems of a knitting machine according to the invention for the production of the spacer knit after 1 ,
  • 1 schematically shows six courses 1 to 6 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 8th in each case the needles of a first needle bed, z. As a dial, and drawn in the lower area, long and short dashes 9 . 10 in each case the needles of a second, the first needle bed opposite needle bed, z. B. a needle cylinder, with the Rippnadeln 7 . 8th and the cylinder needles 9 . 10 z. B. differ by the height or position of their feet. Incidentally, the Rippnadeln stand 7 . 8th and cylinder needles 9 . 10 on gap, ie they are offset from each other by half a needle pitch relative to each other.
  • Next shows 1 that the rows of stitches 1 and 4 are formed with three threads, with a solid thread represented by a solid line 11 a first plating thread shown in dashed lines 12 and a second Plattierfaden shown in phantom 14 , The basic thread 11 Will on all existing cylinder needles 9 . 10 to a mesh 15 respectively. 16 processed. The first plating thread 12 with every second, z. B. odd-numbered cylinder needle 9 into the mesh 15 worked in and laid fast between them, which first floats 17 arise. The second plating thread 14 is with all the rest, z. B. even-numbered cylinder needles 10 into the mesh 16 incorporated and placed between these afloat, 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 formed basic knits, wherein the first plating thread 12 in selected stitches 15 and the second plating thread 14 in the remaining stitches 16 each together with the basic thread 11 is processed to two-thread mesh and is in between afloat. The rib needles 7 and 8th remain in the courses 1 and 4 in a non-knit position.
  • In the courses 2 and 5 comes with a basic thread 19 alone on all rib needles 7 . 8th knitted, creating stitches 20 arise. The courses 2 and 5 thus form a second web in the form of a smooth, with all Rippnadeln 7 . 8th formed basic knits.
  • In the courses 3 and 6 become spacer threads 21a and 21b processed. The spacer threads 21a . 21b may in principle be processed in any manner known per se in spacer knits. In the exemplary embodiment is provided, the spacer threads 21a . 21b consistently connect in the manner of tethers with the first and the second web. The spacer thread 21a is for this purpose z. B. in the course 3 from the odd-numbered cylinder and rib needles 7 and 9 each to a fishing mesh 22 . 23 processed while the spacer thread 21b in the course 6 z. B. only from the even cylinder and Rippnadeln 8th and 10 each as a catch mesh 24 . 25 is involved.
  • A complete section of the spacer knitted fabric thus consists of six courses, followed by further sections with stitches formed in the same way 1 to 6 connect. 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 U1 ). Further, it is possible between the with the spacer threads 21a . 21b formed rows of stitches each more than two rows of basic threads 1 . 2 respectively. 4 . 5 to be provided (eg DE 28 50 823 A1 ). In addition, it would be possible, the Fangmaschen 24 . 25 in the course 6 each with the same needles as in the course 3 to build.
  • For the purposes of the invention, it is important that selected courses (here 1 and 4 ) of the first web at least one in addition to a first basic thread 11 inserted, first plating thread 12 or 14 included, along with the first basic thread 11 to double-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 embodiment are for this purpose accordingly 1 two additional plating threads 12 . 14 in the knitting 1: 1 inserted. Alternatively, it would also be possible, instead of the 1: 1 pattern another pattern, z. B. 1: 2, 2: 2, 1: 3 od. Like. To choose or the first plating thread 12 in the cylinder needles 1 . 2 . 5 . 6 ... etc. and the second plating thread 14 in the cylinder needles 3 . 4 . 7 . 8th ... to 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.
  • That on the basis of 1 described spacer fabric is preferably produced on a circular edge knitting machine, in particular a so-called fine ribbing machine whose main components are shown schematically in FIG 2 to 4 are shown.
  • To 2 For example, 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 at its periphery with conventional, parallel to the machine axis webs 32 is provided. These form grooves between them, in which cylinder needles 33 , Preferably conventional cylinder needles are slidably mounted in the vertical direction. A the needle cylinder 31 surrounding cylinder lock 34 points at one 2 apparent knitting system including lock parts 35 on, which further explained below form Schlossbahnen, in which feet 36 the cylinder needles 33 are guided to give them the usual ejection and withdrawal movements.
  • Above the needle cylinder 31 is a standing opposite this, second needle bed in the form of a dial 37 arranged, preferably together with the needle cylinder 31 is rotatable about the machine axis and on its upper side usual, perpendicular to the machine axis arranged webs 38 having. These form grooves between them, in which rib needles 39 , Preferably conventional latch needles are slidably mounted in the radial direction. The rib needles 39 and the cylinder needles 33 are in the circumferential direction of the needle cylinder 31 offset relative to each other, preferably by half a needle pitch. Above the dial 37 is a ripple lock 40 arranged on the off 2 apparent knitting system, inter alia, with lock parts 41 is provided, which further explained below form Schlossbahnen in which feet 42 the rib needles 39 are guided to give them the usual ejection and withdrawal movements.
  • Finally, according to the knitting system 2 a on a bracket 43 attached thread guide 44 assigned to the cylinder and Rippnadeln 33 . 39 to supply the threads needed 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 for the ejection and withdrawal of the cylinder and Rippnadeln 33 . 39 required lock parts 35 respectively. 41 and thread guides 44 exhibit.
  • Circular knitting machines of the type described are known in the art, inter alia, from the above-identified publications (in particular DE 103 20 533 A1 ) is well known, which is why it is possible to dispense with further explanations here. However, it is clear that in the embodiment of the needle cylinder 31 representative of any self-arbitrary, first needle bed and the dial 37 Representing a standing opposite this, also known per se, second needle bed are shown.
  • 3 . 4a and 4b show an inventive design of the needles (here cylinder and Rippnadeln) of a first and second needle bed and the associated locks (here cylinder and Rippschlösser).
  • For making the courses 1 and 4 of the spacer knit 1 are the grooves of the needle cylinder 31 according to 3 alternately (1: 1) with cylinder needles 46 and 47 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 the lower foot 48 but a medium (deep) foot 50 have that between the lower foot 48 and the upper foot 49 the cylinder needles 46 is arranged. Similarly, the grooves of the dial are 37 according to 4a with rib needles 51a . 51b each with a lower foot 52 and alternately a middle foot 53a or an upper foot 53b exhibit.
  • A cylinder lock 50 ( 3 ) for one for making the courses 1 and 4 suitable knitting system A ( 4a ) is according to the invention with lock parts 55 to 58 provided, the three castle tracks for the three feet 48 . 49 and 50 form. The cylinder lock designed in this way 54 replaced according to the invention in 2 illustrated, known cylinder lock 34 ,
  • One from the castle part 58 formed castle track for the feet 49 the cylinder needles 46 contains, in particular 4a shows a rising section 59a which moves into a knitting position (position II in 4a ), when they reach one in the hook of any cylinder needle 46 located stitch over the tongue on the shaft of the cylinder needle 46 slipped. Another expulsion of the cylinder needles 46 gets through the lower foot 48 prevented, with a lower edge of the lock part 56 interacts.
  • To the section 59a closes a section 60a on, through which the cylinder needle 46 initially withdrawn to the extent that, for example, in one position G1-G1 ( 4a ) one of a yarn guide 61 supplied, the basic thread 11 to 1 corresponding basic thread in the cylinder needle 46 or whose hook is inserted.
  • To the section 60a closes a section 62 along which the cylinder needles 46 is not further lowered so that they are approximately in a position P1-P1 ( 4a ) a the first plating thread 12 ( 1 ) can accommodate corresponding Plattierfaden of a schematically indicated yarn guide 63 is supplied. The foot 49 After that, under the guidance of the foot 48 and the lock part 56 into a canal 64 ( 3 ), in the castle part 58 is incorporated, and is guided by this, that he at another, in the direction of movement or knitting direction v following yarn guide 65 does not pick up any thread by the cylinder needle 46 for example, before passing this yarn guide 65 is sufficiently deep withdrawn. Finally the foot arrives 49 the cylinder needle 46 on a section 66a the associated castle track, along which the cylinder needle 46 is withdrawn to a deepest, the tee position corresponding II-II position to form a mesh with the recorded ground yarn and the first plating thread. The leadership along the section 66a is preferably done with the help of one with the lock part 56 associated or subsequent deduction 67 ( 3 ). This process is repeated for all cylinder needles 46 ,
  • The from the castle part 57 educated, feet 50 the cylinder needles 47 assigned Schlossbahn corresponds to one in 4a dotted area indicated above for the feet 49 the cylinder needles 46 described Schlossbahn, in particular with regard to their sections 59b . 60b and 66b , For a better understanding is the castle track for the feet 50 in 4a However, represented much lower than this is actually the case. As the cylinder needles 46 and 47 in the needle cylinder 31 each next to each other and not, as in 4a is shown, are arranged below one another, 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. Also, in 4a the three yarn guides 61 . 63 and 65 shown again in the area of the lower Schlossbahn. It can be seen that the castle track for the feet 50 essentially only by the feet 49 that distinguishes a section 68 and a section following in the direction of knitting v 69 having. The section 68 serves the purpose of the cylinder needles 47 after picking up the basic thread from the thread guide 61 so deep into an intermediate position that they pass the thread guide 63 does not pick up the first plating thread presented by it, but its hook still remains open. On the other hand has the section 69 the task, the foot 50 and thus the cylinder needle 47 again so high that they drive past the thread guide 65 the supplied by this, the plating thread 14 in 1 corresponding plating thread in addition to the main thread receives (position P2-P2 in 4a ). For safe guidance of the cylinder needles 47 in this area are the sections 68 . 69 preferably accordingly 3 through one in the lock part 57 trained channel 70 realized in the feet 50 with the help of the lock part 56 and the lower feet 48 be steered, which also with the cylinder needles 47 available.
  • Overall, this results in 3 and 4a in that the main thread in the knitting system A is all the cylinder needles 46 and 47 is fed while the first plating thread only in the cylinder needles 46 and the second plating thread only in the cylinder needles 47 is inserted, which is the 1: 1 distribution after 1 equivalent.
  • The lock of the second needle bed, in the embodiment so the Rippschloss 40 ( 2 ), points for in 4a shown feet 53a and 53b the rib needles 51a . 51b in knitting system A only one castle lane 71a respectively. 71b on top of a non knitting of rib needles 51a . 51b corresponds so that they remain idle in system A.
  • In knitting system A thus becomes the course 1 to 1 educated.
  • In knitting system B the 4a is the Rippschloss with usual, leading into a knitting position Austriebsabschnitten 72a respectively. 72b and subsequent, leading to the tee position withdrawal sections 73a . 73b provided analogous to 3 On the feet 52 and 53a . 53b act. This will cause all the rib needles 51a . 51b on the knitting system B is selected for knitting so that it is one of a yarn guide 74 fed, the basic thread 19 to 1 pick up the appropriate basic thread (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 in 4a for clarity, are arranged one behind the other, which is why the two Schlossbahnen a the distance of the feet 53a . 53b have appropriate distance from each other.
  • The cylinder lock has only one track section in the knitting system B. 75a . 75b for the feet 49 . 50 which is essentially a non-knit position for the cylinder needles 46 . 47 corresponds so that they remain idle in system B. This results in knitting system B, the row of stitches 2 to 1 ,
  • In the knitting system C the 4a becomes the spacer thread at a position AF1-AF1 21a to 1 corresponding spacer thread by means of a thread guide 76 fed. For this purpose, the cylinder lock has one each with a Austriebs- and deduction section 77 . 78 provided castle track, the feet alone 49 the cylinder needles 46 assigned. The expulsion section 77 leads to a catch position, so that the spacer thread 21a corresponding 1 only every second cylinder needle in catch position (ie here the cylinder needles 46 ) is supplied. The same applies to the Rippschloss. This has in the knitting system C one with each a Austriebs- and deduction section 79 . 80 provided castle track, the feet alone 53a the rib needles 51a is assigned, so that only these from the thread guide 76 Record supplied spacer thread in catch position. This results in the knitting system C, the row of stitches 3 of the 1 ,
  • According to 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 Systems B, so that a re-description is not required. In the knitting system D thus results in the course 4 and in knitting system E the course 5 of the spacer knit 1 ,
  • In the sixth knitting system F, the spacer thread becomes 21b to 1 corresponding spacer thread by means of a thread guide 81 supplied (position AF2-AF2). In contrast to the knitting system C, the cylinder lock here has one each with a Austriebs- and deduction section 82 . 83 provided castle track on the feet alone 50 the cylinder needles 47 acts, wherein the Austriebsabschnitt 82 leads to the fishing position. Accordingly, the Rippschloss in the knitting system F a leading into the fishing position Austriebsabschnitt 84 and a deduction section 85 on, the feet alone 53b the rib needles 51b assigned. This results in the knitting system F, the row of stitches 6 of the spacer knit 1 ,
  • As an alternative to the procedure described, it would be possible to use the spacer thread in the knitting system 6 in the same way as in the knitting system 3 appeal. In this case, the spacer fabric would consist of a plurality of sections consisting of the three courses 1 to 3 to 1 are formed.
  • When Base and Plattierfäden can in principle all Yarns commonly used in knitting technology. If z. B. both for the basic thread as well as for the plating thread uses a polyester yarn, then results a spacer fabric whose one web in the transverse direction very is little stretchy and their extensibility z. B. only one tenth its what, what with a usual Rippware is reachable. In contrast, z. B. elastomeric threads than Plating threads used, especially in combination with A basic thread made of cotton, then results in a transverse direction particularly elastic web. This can be contrasted to usual spacer knits, in which a plating thread if necessary in addition to the basic thread all cylinder or Ribbed needles can be fed, goods with a completely create a new character. By choosing in particular the elastic properties and / or the number and arrangement of the floats are as well 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 first of all with regard to the use of two plating threads 12 and 14 , For example, it would be possible to omit one of the two plating threads. In this case, z. B. one of the thread guides (eg. 65 ) are missing and the railway section 69 be omitted. Apart from that, the selection means by which the cylinder needles 46 . 47 for receiving the first or second plating thread 12 . 14 and the cylinder and Rippnadeln for receiving the spacer threads 21a . 21b be selected, largely arbitrary. In principle, all agents can be used, as are well known in particular for the production of Jacquard patterns. Instead of the 2 alternatively, a 1: 1 selection could alternatively be a selection in the sense of a 1: 2, 2: 2, 1: 3 pattern or the like for the plating threads 12 . 14 be made, for example, that in the Nadelzylindernuten after a cylinder needle 46 two or three cylinder needles each 47 be 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 that the basic threads 11 and 19 existing webs not with all, but only with selected cylinder and / or Rippnadeln produce, 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 rotating locks. It would also be conceivable, the courses 1 and 4 to 1 with appropriate design of the various components with the dial and the rows of stitches 2 and 5 Finally, it is understood that the various features can also be used in combinations other than those described and illustrated.
