Description

Textile surface product as well as process and Apparatus for making the same

The invention relates to textile fabrics Thread layer stitchbonding machines, e.g., a "Malimo" (TM) machine, and particularly relates to novel ones Malimoware and an apparatus and a method for producing the same. A special weft entry carriage is available for this purpose or sled provided, with the help of which previously unachievable patterns in the textile flat products mentioned can be achieved.

Textile surface products such as pad layer sewn-knitted fabrics show generally a flexible substrate, for example a layer or sheet of substantially parallel, protruding from Selvedge to selvedge extending textile weft elements or weft threads, which with the help of relatively fine knitting, knitting or sewing threads form an integrated structure are united. If the flexible substrate is a layer of textile weft elements, by controlling the spacing between the individual yarn elements a more or less open mesh fabric can be produced. Such textile fabrics and similar fabric structures achieved in the thread layer stitchbonding process can be made with machines in Malimo design Using methods and devices produced in accordance with one of the following US patents: 2,890,579, 3 030 786, 3 253 4-26, 3 274- 806, 3 279 221, 3 309 900,

Purely the economic success of a textile fabric is the ability to easily mass-produce one Base fabric in different patterns is extremely important. With Malimo machines you can make textile fabrics already produce at a relatively high speed compared to the production of fabrics. Dedicated for some time one of improving this desirable property through greater flexibility in the pattern "or in the design great attention, and not only with regard to the density, fineness and color combinations of the individual textile components as well as the distance between them and the deliberate omission of one or more of these elements but also with regard to the spatial design of the textile components in the textile fabric. There is a particular need on layered knitted fabrics or malimo fabrics with even greater versatility in the pattern, especially with regard to the creation of unusual visual impressions. With the invention allows a greater variety of patterns, because there can be several layers of weft yarn elements in total in the width direction or at right angles to the textile fabric at an angle and at different angles to the longitudinal direction. So far there has been no way of doing this with Malimo machines at economically justifiable production speeds To achieve effects.

The object of the invention is to create flat textile products such as those produced on thread layer stitchbonding machines which have greater flexibility in the patterning by the weft component.

The object of the invention is also to create a method and a device for producing textile fabrics

130018/0893

of the aforementioned Art.

To solve the problem on which the invention is based specifically referred to the attached product, process and device claims.

The invention is in novel thread layer stitch-knitted, for example Malimo ware realized with a unique pattern and aesthetic appearance that was previously unachievable. These textile Flat products are produced in a process and with a device, with the help of which the flexible substrate in the manufacture of the product in the form of two or more layers of parallel textile weft elements in predetermined Widths are arranged obliquely across the width of the product and superimposed on one another. This variant of the design of the flexible substrate can not be achieved when using conventional Malimo machines, whose design options the production of thread layer Uähgewirken are limited those of the flexible substrate in the form of a single layer of adjacent or consecutive tapes of only one Width and at a fixed angle (overall somewhat from a right angle to the feed direction to the stitch-forming Elements different).

Textile flat products produced on thread layer knitting machines according to the invention have in particular two or more superimposed weft layers of the same or different width, each consisting of one or more parallel, continuous textile elements or threads, which extend obliquely across the width of the product (doh . from selvage to selvage). The elements of one weft layer can run more or less non-parallel to the elements of another weft layer. Each flat textile product also has a single system of knitted thread ribs which extends in the longitudinal direction of the product, each rib containing a plurality of stitch-like stitch loops which are superimposed on one another.

Weft layers are in engagement and secure them against mutual displacement by stitches lec knitting thread on the back of the product and by the laying of the knitting thread routes on the front of the product. As a result, the weft layers superimposed on one another are tied into an integrated textile fabric structure, the weft thickness of which is twice as great or greater than that of conventional thread layer stitched fabrics. The knitting thread pierces the individual, obliquely arranged textile weft elements at a considerable number of arbitrary points in order to secure the individual components of the product even better against relative displacement.

The textile fabric according to the invention contains one Embodiment two superimposed weft positions, desirably at least a plurality of which contains textile yarn elements that are laid on the back of the product in relation to the other weft layer, for example, so that the rear or lower weft layer becomes a "background layer". The flat textile product preferably has three or more superimposed weft layers of textile yarn elements, at least one of which, for example, has a large number of textile yarn elements and is preferably arranged at the rear of the product in relation to the other weft layers. With textile structures, which appear like open-plan "Homespun" fabrics, like It is typical for curtain and decorative fabrics, the parallel textile elements that make up each individual weft layer "exists, have a greater or lesser distance from one another, to produce this effect. In addition, the invention provides a great variety of colored and / or different textured design patterns possible through the weft layers, which are arranged "undiluted" on a base layer or weft base are. With the invention, for example, a layer of one or more textile weft elements can be placed on top of the textile weft elements an underlying base layer instead of being mixed with these elements and thus in effect to be toned down.

130016/0398

In addition to the aforementioned plurality of superimposed Sc ^v .T 31 layers, the flexible substrate "can optionally be a pre-knitted or pre-woven fabric, an elastomeric foam layer, a fibrous non-woven layer (e.g. a non-woven, spun, fiber composite) or any other continuous layer or flexible structure which can be pierced with a knitting, knitting or sewing thread and thereby attached to the other components of the textile fabric "without the strength being significantly impaired. For this purpose, methods according to the above-mentioned publications can be used which are known to the person skilled in the art in the field of the production of thread-layer hitch-knitted fabrics.

Generally speaking, the device according to the invention provides an improvement over known thread layer seaming machines, from which it originates and which, like this one, has mechanical stitch-forming elements, as they are on paden-layer knitting machines are common. These stitches and stitches forming elements and their mode of operation are known to the person skilled in the art. This includes, for example, a comb-like sinker bar and a comb-like thread bar that jointly delimit an elongated space or a work area and between which the textile surface product is created 'will. It also includes a device for feeding a flexible substrate to the work area and a row of hooks or beard of equipped point needles, as well as corresponding locking wires. In combination with a number of thread guides or knitting thread guides these elements work together in such a way that the threads Pierce the substrate when it moves back and forth between the sinker bar and the thread bar across the work area will. By working in this way, the thread becomes a single system in the longitudinal direction, i.e. more in the machine direction Knitting thread ribs created, each of which has a large number of mesh-like stitch routes along the length of the surface product e.g. in chain stitch or half-tricot stitch design. In particular, the invention provides an improvement in the manner in which the feeding device is used to deliver the flexible substrate to the work area the machine to manufacture the product

to be led. This device has two or more, preferably three or more comb-like or reed-like carriages or sledges in the same or different widths, preferably from 10.16 "to 4-5.72 cm (4" to 18 inches), each synchronously can be moved back and forth with the other car or car. Through this becomes a weft ply of predetermined width selected from a group of one or more parallel, continuous Textile elements are made between two parallel endless rows of hooked blank units (so-called Weft eint raghaken) in -sealing essentially transversely to the direction of movement the weft insertion hook (i.e. across the feed direction the weft positions to the work area) moved back and forth. With the well-known machines in Malimo design, only a double shot transfer can be simulated (by using the Machine runs slowly and the firing carriage runs quickly). With the invention, however, it is possible to actually have several weft positions to lay, so that new decorative effects of the textile surface product result. This is made possible by the inventive device with Xiehrfachwagen and independent Drive.

If textile fabrics are to be produced, in which the a layer of warp elements is superimposed on a flexible substrate consisting of several layers, the machine can be provided with any feed device for warp elements, which together with the flexible substrate and this superimposed one or more chain elements in total feeds in the longitudinal direction. The warp elements are then replaced by the above System of knitting thread ribs in the working area of the machine combined with the substrate. As examples of such procedures for the supply of warp elements, reference is made to US Pat. No. 3,672,187, 3,677,034 and 4,144,727. It should be noted, however, that the presence or absence of warp elements or other textile components and their distribution or design on the textile surface product are not critical features Represent the present invention, in the type of flexible substrate of the textile sheet product as well as the

130016/0898

Means for attaching the same can be seen.

The method according to the invention provides for the "multitude of weft layers of the flexible substrate to be fed to the elongated work area for the production of the textile flat product with the multitude of comb-like weft insertion carriages. and moved forward, whereby a separate layer of the weft elements is fed to the moving rows of hooked board units in a direction substantially transverse to the direction of feed of the substrate to the work area. Simultaneously, the hooked board units move in the direction of feed of the substrate to the work area the comb-like carriages or carriages are timed by means of appropriate gears so that they are moved synchronously with one another, whereby any number of laying patterns of the flexible substrate can be achieved n weft insertion hook is relocated (ie the one furthest upstream of the stitch elements in the work area) is afterwards the rearmost or lowest weft position. The weft position or weft positions subsequently or downstream placed or laid on the weft insertion hooks is superimposed on the previously laid weft position or the weft positions already laid. In the practical implementation of this idea, for example, one or more textile weft elements of a given structure and / or color can be laid using a downstream weft entry carriage so that these elements form a background or base layer of textile elements with different colors and / or different structures are transferred from an upstream arranged weft insertion carriage, are superimposed, d _e h. that they lie on these elements and are not mixed with them (that is, not diluted by them). In addition, e.g. '. the upstream weft insertion carriage can be moved back and forth between the rows of weft insertion hooks at a given speed, which is coupled to the linear speed of the weft insertion hooks

130018/0818

54 058

so that a massive or evenly dense subsurface effect is achieved. The second "or downstream Weft insertion car can then be arranged at any other speed independently of the first or upstream Carriage over the distance between the rows of weft insertion hooks be moved back and forth. In this way, the textile weft element or the weft elements of the top weft layer essentially not parallel to the textile elements of the underground weft layer be arranged across the width of the sheet product. As a result of the direction of movement of the Weft insertion hooks at right angles, i.e. in the transverse direction The reciprocating motion of each weft entry cart stands out the resulting textile fabric according to the invention by a plurality of superimposed layers of essentially parallel, continuous, textile elements that extend diagonally across the width of the product. Ever After the synchronization of the weft insertion carriages, the elements of a weft position can be more or more on the resulting product run less non-parallel to the elements of at least one other layer.

Using the method and the device according to the invention a new thread layer stitch-bonded fabric is produced on a thread layer stitch-bonding machine, e.g. a Malimo machine, which is a flexible substrate in the form of two or more each other superimposed weft layers, each consisting of one or more parallel, continuous textile elements, which are extend obliquely across the width of the product, and has a single system of knitting thread ribs, which extend into Extend the longitudinal direction of the product, and of which each rib has a plurality of mesh-like stitch tours that with the overlaid weft layers are in engagement and these against relative displacement by stitches of the knitting thread secure the back of the product and by stitching the knitting thread turns on the front of the product. The procedure and the device according to the invention provides, the weft layers in the oblique direction between and in engagement with two parallel

len endless rows of hooked blank units with Using the help of a corresponding number of comb-like Viagen, each of which can be moved back and forth in a synchronized manner, and thereby each independently a weft position between the rows of board units back and forth in the direction at right angles to these transport, the rows of board units simultaneously in a direction substantially parallel to the feed direction of the substrate can be moved to the working area of the machine.

The following is the invention with further advantageous details explained in more detail using schematically illustrated embodiments. In the drawings shows:

In Pigο 1, a selvedge-to-selvedge portion is a textile sheet product 1 shown, which has a continuous base layer in Porm of a weft layer 2 and an upper Has design layer in the form of a weft layer 4. How out Pigο 3 shows, the weft layers 2 and 4 are superimposed on one another and by means of a single knitting thread 5 made of mesh-like stitch ribs which extend along the length of the product 1, combined into an integrated, unitary structure. Each rib consists of a multitude of mesh-like ones Stitch tours that are in engagement with the superimposed weft layers 2 and 4 and these against mutual displacement to back up. The knitting thread 5 can be in a known Porm

Chain stitch or half tricot stitch design, of which the latter is preferred if the textile fabric additionally contains warp elements running in the longitudinal direction. These warp elements are not a feature of the flat product shown in the drawings. Only a few such warp elements 6 can be worked into the textile fabric in the vicinity of the edges 7 in order to give the selvedge greater strength. The weft layer 2 consists of a multitude of continuous, parallel textile yarn threads 8 which extend back and forth across the width of the product 1, slightly diagonally or in an oblique direction, ie not at right angles to the longitudinal axis of the product. Similarly, the weft ply 4 consists of a multiplicity of other continuous, parallel textile yarn threads 9, which extend back and forth across the width of the product 1 in a more diagonal or oblique direction than the textile yarn threads 8 of the weft ply 2. The number of adjacent textile yarn threads 8 of the weft layer 2 and the distance between these threads, which are laid with each lifting movement of their associated, upstream weft entry carriage, is coordinated with the stroke frequency of the weft entry carriage and the speed of the weft insertion hook to the working area of the thread layer stitching machine , so that the weft layer is relocated in such a way that the impression of a solid or continuous background is created on which the relatively narrow strips of the weft layer 4 are laid. In this way, an attractive zigzag pattern effect of the weft layer 4 is achieved, which is offset from the contrasting weft layer 2 forming the background. In this regard, the stroke rate is dependent, that is, the reciprocating movement of the upstream carriage for Textilgarnfäden 8 of the movement of the weft insertion hook and stub elements of the yarn layer-knitting machine, while the stroke frequency, d _o h. the reciprocating movement of the downstream carriage for the textile yarn threads 9 is independent of this movement.

In Fig 2 a _o from reaching selvage to selvage portion of a textile product 10 is shown comprising a

130016/0898

has a continuous background in the form of a weft layer 11, a weft layer 12 as a design intermediate layer and a top weft layer 13 as a design layer. The weft layers 11, 12 and 13 are superimposed on one another and connected to a single knitting thread system of one of the types mentioned above and combined to form an integrated, unitary structure, the knitting thread laying engaging the superimposed weft layers and securing them against relative displacement. The weft layer 11 consists of a large number of continuous parallel yarn threads and corresponds overall to the ^{weft layer 2 already described with reference to I 1} Ig ₀ 1, which "forms the background, so that again the impression of a solid or continuous background is created on which the. relatively narrow strips of weft layers 12 and 13 are laid in order to produce the desired overall effect of a diamond pattern,

The weft layers 12 and 1.3 consist of the same or different Multitudes of continuous textile yarn threads with the same or different colors and / or structures, which extend over the width of the textured surface product 10 and extend forward, in each case in a more diagonal or oblique direction than the yarn elements of the background TDiI-denden Weft position 11 and under the same or different Angles in relation to each other. In this way, the stroke frequencies of the carriages for the weft positions 12 and 13 are each independent of the stroke frequency of the carriage for the weft position 11 forming the background and can also be independent of one another be or not, the last-mentioned ratio being dependent on the one desired to be achieved with the two weft layers 12 and 13 figurative pattern depends.

According to I ¹ Ig. 4, a thread layer knitting machine 20 has a work area 21 for creating a padenlage liähgewirks and a feed device 22 for the substrate, which carries a flexible substrate, for example in the form of a plurality of "continuous textile weft yarn elements 23, which by means of a here

The feed device 22 for the substrate is typically two parallel, the person skilled in "known endless rows of hook-shaped Sinker units or weft insertion hooks'. Optionally, a feed device, not shown here, for warp yarn elements be provided, which together with the substrate and superimposed thereon, a plurality of overall length extending in the longitudinal direction Warp elements feeds which are combined with the substrate in the work area 21.

The work area 21 in which the textile fabric is manufactured is, typically has a comb-like sinker bar and a comb-like needle bar, between which a Elongated space or work area limited across the width of the machine for the manufacture of the product is. A row of whipped or hooked pointed needles, each with a locking wire associated with it, is for penetration into the weft elements 23 of the substrate and into the optionally provided warp elements in cooperation with a row of guides for yarn threads 24 are provided with which a large number ribbed stitch chain stitches are formed, which combine the individual components of the product and Tie together in a unitary 'non-woven textile structure 25.

In the embodiment shown in FIG. 4, the inventive Apparatus three 'comb-like weft insertion carriages 26, 27 and 28, the weft yarn elements 23 from an eyelet board 29 obtained and the yarns on oppositely arranged rows of weft insertion hooks dispense by moving between the rows in a direction substantially transverse or perpendicular to the direction reciprocated herden, in "which the rows the substrate to Work area 21 lead. The weft insertion carriages 26, 27 and 28, which are one downstream, one in the middle and one upstream "'is arranged car, contain" each one comb-like reed or sheet 51, with the help of which a multitude weft yarns to be entered separately from one another at intervals

will hold to the weft insertion hooks "of the rows of the feeder 22 to be submitted. It lsi; advantageous if two presser feet are provided on both sides of each trolley for this purpose with which the weft yarn elements 23 with the rows of hooks to be printed in engagement. The presser feet are with a pest control device for the end of the movement path, e.g. coupled with buffers or stop links to that of the row of hooks to lift the adjacent presser foot and the opposite of the "row Lower the presser foot when the carriage presses the yarn over the hook. Said coupling can expediently be made by means of a rack and pinion transmission. It An adjustable end stop member can also be provided in order to set the exact position for actuating the presser foot.

According to the invention, the weft insertion carriages 26, 27 and 28 are independently controllable in order to deliver the weft yarns in three separate layers to the weft insertion hooks. Appropriately, the weft insertion carriages 2S ₁ 27 and 28 can be moved back and forth by means of timing belts (not shown here) and with the help of rollers 30 on guide rods 31 j which are attached to support members, for example support members 32. The timing belts are driven and guided by chain wheels, which in turn are rotatably mounted in the vicinity of the support members 32. Each drive sprocket is expediently driven by a drive chain, the movement of which can be controlled by means of devices which are obvious to the pachmann in view of the present disclosure. A suitable drive device for driving each weft entry carriage in a reciprocating motion basically has, for example, a Uockenarm attached to a drive wheel for a vertically reciprocating horizontal rod, the movement of which is coupled to a rotatable shaft via chains and sprockets not shown here .
