Abstract

The invention relates to a circular knitting machine for multicolored plush. A plush sinker (113) is provided with at least two planes (90, 91) for kinking loop threads of different loop length. The knocking-over sinker (112) has a bill comprising at least two webs (96, 97) for restretching pile loops of different loop length. Plush knitted goods having plush loops of different heights and different colors can be produced by means of said circular knitting machine. Knitted goods being combined of epinglé and velour can thus be produced by shearing the longer plush loops.

Description

The invention relates to a circular knitting machine according to claim 1. Furthermore, the invention relates to a method for producing plush knit fabric having a basic knit formed by a basic thread and plush loops, according to claim 4.

It is known to provide knitted fabric with one or both sides protruding from the fabric base thread loops or handles. Such knitwear is called plush. If the loops protruding from the product base are left as closed handles, a so-called Epinglee surface is created. Likewise, it is possible to cut off the sweeping of the handles, so that standing out of the fabric reason individual filaments remain. In this case you get a so-called velor surface.

1. a) eine Reihe kreisförmig angeordneter Nadeln zur Bildung der Maschen und Henkel, deren Auf- und Abbewegung durch ein Nadelschloss entlang einer Nadelkurve geregelt wird;
2. b) eine Einschließ- und Abschlagplatine (im folgenden kurz Einschließplatine genannt) sowie eine Plüschplatine, wobei die Einschließplatine und die Plüschplatine parallel zueinander zwischen je zwei Nadeln angeordnet sind und eine zu den Nadeln waagerechte Hin- und Herbewegung ausführen können, die durch ein Platinenschloss entlang einer ersten Platinenkurve für die Einschließ- und Abschlagplatine und einer anderen Platinenkurve für die Plüschplatine geregelt wird;
3. c) Steuerelemente zur mustergemäßen Nadelauswahl, wobei die Auswahl einer Nadel dazu führt, dass diese der an ihrem momentanen Aufenthaltsort vorliegenden Nadelkurve folgt, während eine nicht ausgewählte Nadel in einer Grundstellung (Rundlaufstellung) verbleibt,
4. d) Fadenführungsmittel für die Zufuhr von einem Grundfaden sowie von mindestens zwei Henkelfäden zur Erzeugung der Plüschhenkel.

The production of plush knitwear can be done in particular in a circular knitting machine. Circular knitting machines of known type contain the following elements:

1. a) a series of circularly arranged needles to form the stitches and handles whose up and down movement is controlled by a needle lock along a needle curve;
2. b) an embedding and debarking board (hereinafter referred to as Einschließplatine) and a plush board, wherein the Einschließplatine and the plush board are arranged parallel to each other between two needles and can perform a horizontal to the needles reciprocating through a board lock along a first circuit board curve for the containment and debit board and another board curve is regulated for the plush board;
3. c) needle selection control elements, wherein the selection of a needle results in following the needle curve present at its current location while leaving a non-selected needle in a home position (concentricity);
4. d) yarn guide means for the supply of a ground yarn and at least two handle threads to produce the plush loops.

In such a circular knitting machine, it is possible to determine for a certain mesh of knit fabric produced via the controls, whether in this stitch with the first and / or the second thread filament, a plush should be formed or not. The production of a plush hook takes place only when the needle belonging to this mesh is selected by the control elements when the said loop passes the respective thread filament. By using different yarns for the handle threads, it is possible to produce plush loops of different color or yarn quality.

The height of the plush lounger sticking out of the fabric base is checked in the circular knitting machine with the plush board, over the upper edge of which the thread filament is held back while the needle draws a loop downwards out of the thread (so-called precoating).

Further details on the structure and functioning of circular knitting machines can be found, for example, in the book "Rundstricken - Theory and Practice of Mesh Techniques" by lyer, Mammel, Schäch - Bamberg: Meisenbach (1991).

The JP 07-042050 A shows a board with two levels. Furthermore, the document shows plush knitwear that Henkel has different length.

The EP 0 594 187 A1 shows a circular knitting machine with two different boards for producing plush knit fabric with a handle height.

The EP 0 757 124 A1 shows a circular knitting machine with a board that has two levels and plush knitwear, which has only one handle length.

Object of the present invention was to provide a plush knitwear and a suitable for their production circular knitting machine, the knitted fabric should have a novel, visually appealing structure.

This object is achieved by a circular knitting machine according to the subject-matter of claim 1 and by a method for producing plush knitted fabric according to the subject-matter of claim 4.

As explained above, the length of a plush hook is determined by the height of the top of a plush board. Conventional plush boards have only one for coining the handle thread Upper edge, so that the handle length (also called pole height) is the same size for all plush loops. In the plush board of the circular knitting machine according to the invention, on the other hand, two levels are formed on the plush board for the coiling of a handle thread, which are located at different altitudes and accordingly lead to different pile heights of the handle threads on the respective level. Which level is used for the Kulierung a Henkel thread, can be determined by the extent of the radial feed of the plush board. The plane to be used for coagulation must be advanced to the needle circle.

By using the plush board it is possible to produce plush loops of different pile heights. By using the plush board in a circular knitting machine, which can process at least two handle threads, plush loops of different heights can thus be produced from respectively different yarn material.

Furthermore, an enclosing and debarking board (hereinafter referred to as enclosing board) of the circular knitting machine according to the invention has at least two levels for retightening a handle thread. Such Einschließplatine is used in the circular knitting machine according to the invention to re-tension handle threads form plush loops of different pile height. The tensioning of the handle threads of plush loops is basically known and serves to guarantee a firm and uniform fit of the plush loops in the ground. To enable the re-tensioning the Einschließplatine is provided with a beak, which receives the plush loops of several earlier educated rows again and slightly re-tensioning, so that their anchoring in the ground is improved and the handle length is made uniform. The upper edge of the beak forms the plane for the tensioning of the plush loops, so that their altitude must correspond to the pile height of the plush loops.

In known Einschließplatinen usually only one level at a given height for tensioning the Plüschhenkel is available. In the case of the present containment board, on the other hand, there are at least two levels for retightening the handle thread, so that this containment board is also used during production a knit fabric can be used with plush loops of different pile height.

1. a) Nadeln zur Bildung von Maschen und Plüschhenkeln, deren Auf- und Abbewegung durch ein Nadelschloss entlang einer Nadelkurve geregelt wird,
2. b) eine Einschließ- und Abschlagplatine sowie eine Plüschplatine, welche parallel zueinander angeordnet sind und deren zu den Nadeln beziehungsweise zu der Nadelbewegung senkrechte Hin- und Herbewegung durch ein Platindnschloss entlang je einer Platinenkurve für die Einschließplatine beziehungsweise Plüschplatine geregelt wird,
3. c) Steuerelemente zur mustergemäßen Nadelauswahl, wobei eine ausgewählte Nadel der an ihrem Aufenthaltsort vorliegenden Nadelkurve folgt,
4. d) Fadenführungsmittel für die Zufuhr von einem Grundfaden sowie mindestens zwei Henkelfäden.

The invention relates to a circular knitting machine for the production of plush knitwear, which contains the following elements:

1. a) Needles for forming stitches and plush loops whose up and down movement is controlled by a needle lock along a needle cam,
2. b) an embedding and debarking board and a plush board, which are arranged parallel to each other and whose perpendicular to the needles or to the needle movement back and forth movement is regulated by a Platindnschloss along a respective board curve for the Einschließplatine or plush board
3. c) needle selection control elements, wherein a selected needle follows the needle curve present at its location,
4. d) yarn guide means for the supply of a ground yarn and at least two handle threads.

The circular knitting machine is characterized in that it includes a plush board of the type explained above. Such a plush board, due to its two levels of coiling a handle thread, allows a plush knit of different handle length (pile height) to be made, and the plush loops of different lengths may additionally differ in the material of the handle thread (i.e., yarn quality, color, etc.).

Said circular knitting machine further comprises an embedding and debarking board of the type described above, which has at least two levels for tensioning a handle thread. With such a Einschießplatine can be ensured that the different handle systems different pole height are all individually restrained and thus all are firmly anchored in the ground.

Finally, the invention relates to a method for the production of plush knitwear with a basic knit formed by a basic thread and plush loops. The plush knit fabric is characterized in that there are at least two groups of plush loops, the plush loops a group differing in handle height and type of thread from those of the other group (s). Due to the different pile height of the plush loops, this plush knit fabric has an aesthetically pleasing, structured high-low optic, which is additionally supported by the fact that the plush loops of different heights are formed of different materials, which may in particular include different colors.

Preferably, the plush knit fabric is further processed in that the higher plush loops are sheared off, so that arise from each plush loops two projecting from the fabric bottom end threads. Such shearing results in a surface called a velor. Since according to the invention only the higher plush loops are sheared, the lower plush loops remain unopened as loops and form a so-called Epinglee. Overall, the plush knitwear thus has in its structure a mixture of velor and Epinglee, wherein the two underlying thread systems materials may differ in their nature and in particular color.

In FIG. 1 To illustrate the phrase used is a section of a circular knit fabric shown schematically. In the center of the illustration, a single stitch 20 is shown highlighted in black as a building block of the knitwear. The loop 20 consists of a stitch loop which is held at its two lower ends (the feet) by the stitch head of the preceding loop stitch and whose loop head in turn holds the feet of the subsequent stitch. This results in a total of a dimensionally stable mesh. The mesh is divided into wales 23 in the horizontal direction (running direction of the thread) and wales 24 in the vertical direction.

The continuation of the mesh forming threads is indicated for a circular knit by a dotted continuation line 21 for a first thread and a solid continuation line 22 for a second thread. It can be seen that the threads rotate in a spiral manner. To accelerate the knitting process and, where appropriate, for pattern formation, two or generally even more threads may form parallel, nested spirals, as shown in FIG FIG. 1 the example of two threads 21, 22 is indicated.

In FIG. 2 an enlarged section of a plush knitwear is shown schematically. The lower row of stitches shown here consists of three basically parallel threads, namely the background thread G, through which the basic knit or the fabric base is formed. Parallel to this run two different handle threads F1 and F2, which may consist in particular of different material with different colors. The handle thread F1 (dotted line) follows from the left to the right in the first stitch the background thread G, but then forms on the connecting piece between the first stitch and the second stitch (so-called board mesh) a loop that is to be imagined from the ground upwards projecting and is referred to as a so-called Plush handle 32. The formation of such plush loops is basically known and leads to an Epinglee structure. Subsequently, the first threading thread F1 follows the background thread G in parallel in the second stitch and in the third stitch.

The second thread F2 (dashed line) runs from left to right in the first stitch also parallel to the ground thread, then continues parallel to the background thread G to the second stitch, through which it follows the ground thread G in parallel. Between the second stitch and the third stitch, it forms a plush looper 31. Following this plush looper 31, the handle thread F 2 again follows the ground thread through the third stitch.

Of importance in the meshwork Fig. 2 is that the first Plühenhenkei 32 and the second Plush handle 31 have different handle lengths (pile heights) and that they additionally consist of different threads F1 and F2, which may differ, for example, in their color. As a result, creative freedom is opened, which allow an aesthetically pleasing high-low structure of plush knitwear with Epinglee different pile height and different color.

Furthermore, it is possible to shear the knitwear in a post-processing and thereby cut open the loops of the longer plush loops 31 along a parting line 33. As a result, the initially closed plush loops 31 are projecting from the basic knit monofilaments, which form a so-called velor structure. The knitwear is thus an epinglee a first color combined with a velor of a second color (or yarn quality).

In FIG. 3 is schematically outlined the operation of a circular knitting machine. Evident is the basic course of the base thread G and two handle threads F1 and F2, which belong to a first so-called system group X. This means that these three threads are processed in a course with each other, as for example in FIG. 2 is shown.

In the FIG. 3 From the right coming threads G, F1, F2 run a total of spirally along the tubular circular knit. That means that the three threads on the left end of FIG. 3 Step into the background and spiral to the right edge of FIG. 3 run back where they arrive at the corresponding points marked G. F1 and F2.

The threads G ', F1' and F2 'of a second system group take an analogous course. The two parallel and helical thread systems G, F1, F1 and G ', F1 and F2' thus correspond to the two individual threads 21 and 22 FIG. 1 , Further thread systems to other system groups are indicated by dots.

Furthermore, in FIG. 3 schematically indicated that the respective threads G, F1, F2 and G ', F1' and F2 'to thread feeders 40 and 41, where the corresponding materials are stored on bobbins and from where they fed to the respective processing site on the circular knitting machine via a yarn guide become.

In FIG. 3 Furthermore, the needles 10, which run parallel to and perpendicular to the threads, of a so-called system group X are shown schematically. The system group X consists of a basic system G1, whose needles make the knitting of the basic thread G, and two handle systems H1 and H2, which entangle the first thread filament F1 and the second thread filament F2 in the associated stitch row.

In the FIG. 3 shown system group X is to the left and right by on a circular path (so-called needle circle) arranged further system groups continued to think. The right adjacent system group (not shown) serves to entangle the three threads G ', F1' and F2 '.

In FIG. 4 two needles 10a, 10b and two Einschließplatinen.12a, 12b and two plush boards 13a, 13b are shown in perspective. Such a changing sequence of needles and sinkers is to be imagined in the circular knitting machine on the needle circle 18 running all around, so that each wale is processed by exactly one needle.

The needles 10a, 10b and the sinkers 12a, 12b, 13a, 13b, on the one hand, together with the knitwear, perform a circular movement along the needle circle 18, which in FIG FIG. 4 indicated by the arrow 1. During this circular motion, the needles 10a, 10b additionally move up and down (double arrow) to catch, if necessary, the thread 50 passing through a stationary thread guide 51 and to compress over the upper edges of the insertion plates 12a, 12b, that is to say a loop from there form. This loop can then be pulled in particular by the last mesh formed by the needle 10a or 10b, whereby the latter stitch is cut off and from the thread 50, a new stitch is formed. Such a loop formation from the thread 50 takes place only when the needle 10a or 10b has been expelled in accordance with a pattern-dependent control program for catching the thread 50. On the other hand, if a needle remains in the so-called concentric position, the thread 50 is not caught by it and runs as a float along the corresponding wale.

The Einschließplatinen 12a, 12b and the plush boards 13a, 13b can be reciprocated perpendicular to the needles 10a, 10b (double arrow), so as to provide on the needle circle the respectively required edge height for supporting the thread 50 or the knitted fabric 52. Each one Einschließplatine and a plush board are guided parallel in a circuit board channel.

Below is with the help of FIGS. 5 to 10 described the specific embodiment of a circular knitting machine, with which the in FIG. 2 illustrated knit fabric when using a plush board 113 according to FIG. 21 and a containment board 112 according to FIG FIG. 22 can be produced. The illustration applies to the basic explanation of the production of two-tone plush and takes place thus using Einschließplatinen 12 or plush boards 13 according to the prior art.

The machine selected to make the combined Epinglee velor knit is a right / left circular knitting machine with electronically controlled single needle selection. Such a machine is used to make jacquard patterned right / left shear plush knits. A special feature of this knitwear is the special processing of several handle threads (plush threads) within a basic thread row. The handle threads are entangled by selected needles to plush loops. If the needle is not selected, the thread filament forms a float, which is cut away in the equipment of the knitted fabric.

The stitching and plushing of a row of stitches takes place in each case within a system group of the circular knitting machine. One basic and one to five handle systems each form a course. The number of handle systems of a system group is determined by the number of plush colors to be processed. The Plüschhenkel- and stitching is done by a Doppelplatinentechnik, in which each board channel leads a plush and an embarkation and debarking board.

FIG. 5 shows in the lower part a side view of the operating side of the so-called cylinder lock of the circular knitting machine. The cylinder lock surrounds the circular knitting machine once circular and is divided into individual segments 17. The segments contain on their (in FIG. 5 not visible) inside so-called lock channels, in which a needle 10 is guided with a corresponding foot to follow the vertical course of the lock channel, which produces the desired up and down movement of the needle 10.

The leadership of the needle is out FIG. 6 more understandable, which is a cross section along the line VI-VI of FIG. 5 shows. There, a needle 10 can be seen, which is mounted in a vertical channel of the cylinder 19. The cylinder 19 rotates during the work of the circular knitting machine, taking with it the needle 10 and the knitwear hanging therein. Opposite the rotating cylinder 19, the cylinder lock is fixed, which consists of the needle lock N1 and the control board lock S2. In the above-mentioned castle channel at the Inside the needle lock N1 hooks the needle 10 with a foot and is thus moved in the relative movement between the cylinder 19 and cylinder lock in accordance with the vertical course of the lock channel up and down.

The adjusting in this way up and down movement of the needle 10 is in FIG. 5 above the cylinder lock by the so-called cylinder needle curve or short needle curve 66 shown. It can be seen that the cylinder lock in the circumferential direction of the circular knitting machine can be summarized in functionally independent system groups X. Each system group X starts with a basic system G1, which is followed by one, two, three or more handle systems H1, H2, H3, ..., depending on the number of handle colors. A system group with two handle systems is in FIG. 5 while a system group X with a handle system H1 in FIG FIG. 7 and a system group X with three handle systems H1, H2, H3 in FIG. 8 is shown. Accordingly, with the cylinder needle curve of FIG. 7 monochrome plush, with the cylinder needle curve of FIG. 5 two-tone plush and with the cylinder needle curve of FIG. 8 tricolor plush.

The basic system G1 is assigned to the processing (entanglement) of a basic thread G. In the handle system H1, the processing of a first handle thread F1 with a first color and correspondingly in the second and optionally third handle system H2 or H3, the processing of a second or third handle thread with a second or third color. In each system group, the base system and the handle systems together form a plush stitch row, each stitch of the row preferably containing a handle (cf. FIG. 2 ).

2. b) das Auswählen, Steuern und Führen der Steuerplatinen 11.

The needles 10 and the Einschließplatinen 12 and plush boards 13 pass through in FIG. 5 Cylinder lock shown from right to left in the direction of arrow 1. The in the FIGS. 5 and 6 cylinder lock shown fulfills two complementary tasks with respect to the needles 10, namely

1. a) controlling and guiding the needles 10, and
2. b) selecting, controlling and guiding the control boards 11.

Exercise a) is performed in the upper lock area, the needle lock N1, while task part b) in the lower lock area, the control board lock S2 is performed. In the systems G1, H1 and H2, the needle lock N1 and the control board lock S2 fulfill the following functions in detail:

Basic system G1, area control board lock S2:

Lock area for guiding the control boards 11 in concentricity. The control boards pass through the lock in a concentricity position and are prepared for pattern selection on the following handle system H1.

Basic system G1, needle lock area N1:

The basic system G1 initially has a stitch knitting area G1.X in the needle lock N1 in the direction of the machine, followed by a needle discharge and needle feed area G1.1. Both areas G1.X and G1.1 are combined in a basic system G1.

Mesh Abrasion Area G1.X:

The knitted fabric area G1.X is the end area of each system group X. In this area, the stitches and stitches of one course prepared in the foregoing system group X are completely formed and chipped.

Needle ejection and needle feed area G1.1:

The Nadelaustriebs- and Nadeleinzugsbereich G1.1 is the beginning of a system group X. All needles are raised in knitting position and capture during their retracting movement of the main thread. The stitches of the basic thread series are prepared by pre-emulating the basic thread for grinding. The needles are pulled off only on catch on the needle. The old stitch is not cut off, it remains on the closed tongue of the needle.

Handle system H1, area control board lock S2:

Lock area for selecting, guiding and controlling the control boards 11 in the concentricity or knitting position. The control boards lift the associated needles 10 in the knitting position or leave them in the concentric position.

Handle system H1, range needle lock N1:

Lock area for guiding and controlling the needles 10 in concentric or knitting position. Needles raised in the knitting position grasp the handle thread of color 1, form a handle and are pulled off until caught on the needle. Concentrated needles form a float with color 1.

FIG. 9 shows in the lower left part of the supervision on the operating side of a board lock for system group X from FIG. 5 , The board lock is divided into individual segments 16, which on their inside (not shown) have grooves that in the upper part of FIG. 9 shown course corresponding to the board curves 69, 71 have.

As from the right in FIG. 9 shown cross-section along the line IX-IX can be seen, the Einschließplatine 12 and the plush board 13 are guided with corresponding extensions in the grooves or castle curves 14 for the Einschließplatine or 15 for the plush board. As a result, they execute a movement perpendicular to the needle or to the needle circle 18, 18 '. This (in relation to the rotating cylinder) radial movement of the boards 12, 13 takes place when the juxtaposed boards move in the direction of arrow 1 through the segments 16 of the board lock.

The system groups X on the board lock and on the cylinder lock must always have the same system layout opposite one another, so that needles and boards can interact synchronously in the desired manner. FIG. 9 thus sets the example FIG. 5 in which a two-color plush of a base system G1 and two handle systems H1, H2 is produced.

The function of the board locks in relation to the system group X is as follows:

Basic system G1:

Plush and entrapment boards are retracted from the needle circle during the complete formation of the stitches and handles (end area G1.X). In the needle feed area (starting area G1.1), both boards are advanced to the needle circle to prepare the basic mesh line.

Handle Systems H1, H2, H3:

The containment boards pass through these systems in a slightly retracted position and remain functionless. The plush boards are in the advanced position to the needle circle and form the plush loops. The functions of the handle systems H1, H2, H3 are identical.

In FIG. 10 For the system group X, the needle cam 66, the board curve 69 of the Einschließplatine 12 and the board curve 71 of the plush board 13 are shown in parallel. From the compilation, the following explained interaction of the elements will be apparent.

The stitching and stitching of a row of stitches takes place within the system group X, which consists of a basic system G1 and two handle systems H1, H2. The different needle positions I to X refer to the FIGS. 11 to 20 and correspond to the mesh and handle forming process on the individual systems.

Evident is the needle curve 66, which describes the head of the needle 10 in the direction of movement 65 with respect to the lower stitch edge 60 of the Einschließplatine 12. Underneath is the curve 69 of the containment board 12 (containment throat). The arrow 68 marks the direction of movement of the containment boards with respect to the needle circle 67. The bottom diagram shows the curve 70 of the plush board 13 (vertical press-off edge). The arrow 70 marks the direction of movement of the plush board with respect to the needle circle 67th

Also shown are the upper tee edge 61 and the containment throat 62 of the containment board, the upper tee edge 64 and the lower tee edge 63 of the plush board 13, and the direction of travel 1 of the needles and sinkers in the circumferential direction.

The needle and sinker functions in the stitch and loop forming operations on the various systems are as follows:

Basic system G1, starting area G1.1:

All needles are driven out in the knitting position, pick up the basic thread and are pulled in until they catch on the needle (needle positions I to III).

Handle system H1:

Needles for color 1 are driven out according to the pattern in the knitting position, take up the plush thread (color 1) and are pulled in until the catch on the needle. Concentrated needles form a float (needle positions IV to VI).

Handle system H2:

Needles for color 2 are driven out according to the pattern in the knitting position, take up the plush thread (color 2) and are retracted until caught on the needle. Concentrated needles form a float (needle positions VII to IX).

Basic System G1, Abrasion Area G1.X:

All needles are fed into the final stitching position. All stitches in a course are finished (needle position X).

The production of bicoloured plush is in the individual phases in the FIGS. 11 to 20 shown. Here are a Einschließplatine 112 and a plush board 113 use.

The functional area of the plush board 113 is in FIG. 21 shown in more detail. Evident are the two parallel planes 90, 91, which offers the plush board 113 on its upper side, in order to be able to use this to mold a handle thread. Which of the levels 90, 91 is used for the Kulierung, can be controlled by the radial feed of the plush board 113.

The containment and deburring board 112 includes as shown FIG. 22 as known Einschließplatinen a knock-off edge 98, via which the knocking off of the finished stitch takes place, and an upper edge 95, over which the thread is gekuliert. However, unlike conventional plush containment boards, the containment board 112 includes a split nose with the parallel lands 96 and 97. These lands serve to retighten plush loops of previous stitches. Since plush loops of different pile height are knitted according to the invention, the re-tensioning takes place via the edge 96 or 97 which is suitable for the respective pile height.

Of course, the production of Plümasmaschenware with more than two handle systems is possible, the plush board in this case accordingly many of the planing levels and the Einschließplatine corresponding to many webs would have to retighten.

According to the FIGS. 11 to 20 is a system group X in a circular knitting machine according to the invention in the following steps:

Needle position I, Fig. 11 (basic system G1, starting area G1.1, ground thread):

Basic position of needle 10, containment board 112 and plush board 113.

The needle is in a concentric position. The needle head is flush with the lower stitch edge 98 of the containment board 112. In the needle head, the last formed two-ply stitch of base and thread filament hangs. The plush board is advanced to the needle.

Needle position II, Fig. 12 (Basic system G1, middle range G1.1, basic thread):
