Abstract

Process to treat tubular textiles completely in one work process comprises determining distribution and position angle of products through product diameter. The distribution (2) and position angle (3) of the products are determined through the product diameter. On the basis of the angle, the aggregate rows (9,10; 13,14) of the planes (8,12) are arrangement symmetrically in themselves and asymmetrically in relation to each other.

Description

The present invention relates to process engineering and methodology and thereby to machine technology for the finishing and finishing of the "strip, edge- and contour-free tubular fabric "in various textile processing processes. So far, no process and thus no machine technology is known in the textile industry with which a tubular product continuously in a circular shape according to patent claims 2,3 and 4, edged without stripes, stripes, contours and thus products according to claim 5 could be produced.

The invention is based on the object, the process and the machine technology apply that this eliminates the disadvantages known from the prior art, body-size-compatible clothing in all common clothing sizes without side seams, the optical elimination of the disadvantageous spiral of the knitted fabric after the assembly enables cut waste to be reduced and additional ready-made, design, offers design-related (e.g. continuous designs) and creative advantages.

State of the art:

The invention relates mainly to the finishing and finishing of the hose manufactured textile structures, preferably knitted fabrics from the circular knitting machines. Due to the technical versatility of the new technology, flat products can also be manufactured Textile structures (woven, rustled and non-woven goods) were formed into a tube Procedures apply.

There are different forms of textile processing Tubular goods. Fig. 2 represents a cut and open tubular product, Fig. 3 a flat / smooth tubular product and Fig. 4 represents a circular tubular fabric. In today's technology Known methods mainly use goods according to Fig.2 and Fig.3. Because of the disadvantageous edge rolling behavior of the cut tubular goods, the Circular knitwear processed as flat tubular goods, which processing requires in most cases There are two process gears for the front and back of the material However, there is a turning device in some processes (e.g. roughening, sanding) Possibility to continuously edit the front and back.

Maengel conventional process engineering:

Taking into account the wet, dry equipment and the printing house, the Processing in tubular form compared to open processing form of knitted textile goods is more efficient and economical technology. However, this type of processing is due to the known processing problems have decreased significantly in recent years must go through each process twice with the front and back, where the disturbing edge and contour streak cannot be avoided. (Fig.5) The processing of the front and back sides increases operational and internal transport costs significantly.

The technical and technological conditions can be the first and the second Goods flow may be different and unequal equipment and printing effects These adversely affect the look of the goods and further processing in the assembly. Another disadvantage comes with the spiral of the knitted fabrics only after the assembly The print history, print quality and coloring are not correct in the print shop With open tubular goods (Fig. 2), it is necessary to manage the goods and to remove the Edge rolling of an expensive paper holding technology Problems are additionally used glue that washed out at the expense of ecology In the production of open goods, the untreated side edges are between 2-5 cm. These edges automatically represent material waste. The side seams or higher Proportion of cutting waste up to 25% in the assembly cannot be avoided Tubular goods were used in the textile industry as spreader bars or treatment methods for aqueous medium developed. DE 2949876 is such a spreader for tubular goods with a central carrier for several arranged inside, held outside Known spreadable adjustable supports with longitudinal elements known over the circumference, on which attached rollers are located transversely to the direction of travel of the tubular goods

This system is only used to keep the tubular goods wide two adjacent roles in the transverse plane cannot be avoided and leave one precise refinement and finishing process in the specified technique not to..Im Treatment medium with water (e.g. washing, bleaching, mercerizing) and with hot air (e.g. Drying, fixing) this system only ensures that the tubular goods are held more securely a security.

EP 0 297 039 A1 in turn is a washing device for fixed tubular goods This system is also used for a wet medium.

Description of process engineering and methodology

The application and methodology of the process is carried out on the cylindrical guide body by means of shearing, roughing, sanding, scorching, embossing, printing, etc. 15-16-17. This technique was based on a circumference division methodology. The diameter of the tubular goods to be processed and the textile effect to be expected determine the division factor (AF) and the associated division angle (α _AT ) The required textile application effect (VE) per pair of rows (E1, E2, E3 etc.) requires at least two rows of units arranged symmetrically one above the other on the circular circumference of the tubular goods (unit rows A and B). These rows of units A and B, which are placed one above the other, must have the same spacing and relationship to one another in terms of symmetry. The asymmetrical arrangement of rows A and B is determined by the angle of arrangement (α _AN ), which is the angle of division (α _AT ). The distance between the rows of units is mainly determined by the dimensions of the technology used and can be variable. The functional interaction of the symmetrically and asymmetrically arranged units on a circular textile fabric on the guide body fulfills the comprehensive completion of the process application over the entire scope. At the interfaces or the contact points (BP), (= zero point of the arrangement angle (α _AN ) of the unit pairs [1A (3) with 1B (4)] and [1A (5) with 1B (6) etc.] the Rows (A) and (B) on the surface of the circular tubular goods are completed to complete the contour-free and marking-free processing. The only decisive and decisive factor here is continuous textile processing of the circular tubular goods using the technique shown and in a single operation Explanation, structure and mode of operation of the illustrated invention based on an example of execution with an 8-fold division (AF) and the corresponding drawings depending on the raw material used (yarn), the quality of the goods (type of binding) and properties (equipment ung) vary greatly from one another and must be determined according to the nature of the goods as operational know-how.

Fig. 2 provides the mostly used cut / open tubular goods for wide treatment Tubular goods / width (1) and rolled edges as problem areas (2). Fig.3 shows a flat or Smooth tubular fabric for direct tube treatment. In this case, tubular fabric is used presented to the machines in a sheet-like manner, treatment takes place on the front and back, i.e. At least two passages would be required. Fig. 4 symbolizes the circular tubular fabric circular processing, on which the claim is based. Figure 5 shows edge and Contour defects in a bird's eye view (1) and the front view (2) on a tubular fabric in processing according to Fig. 3 As untreated, unprinted, uneven areas in the longest direction (marked areas).

In the drawings (Fig. 6 and Fig. 7), the systematics and principle of the circular circumference division method are illustrated using examples. The circumference of the circular tubular goods is, depending on the finishing process or the pressure effect, with the intended division factor (AF- in the example 8-fold) (2) to determine the distribution (α _AT ) (1) and arrangement angle (α _AN ) (3), from which the dimensions and diameter of the unit technology can be determined later. The factor with which the number of to be used is a variable size, which is determined by the diameter of the tubular fabric and the expected textile effect. Distribution factors between 8-18 times per scope and more will usually be used. The formula is simplified: Splitting / arrangement angle = 360 degrees / splitting factor AF, AF = (number of intended units per pair of levels) Splitting / arrangement angle = 360 degrees / 8-fold = 45 degrees

18 is a schematic representation of the goods management, process and Machine technology on the basis of the patent claims. The tension-free, presented flat tubular goods - dotted - (1) with a first Preload (3) is fed to the inlet-take-off roller pair (4). At this point, the Tubular goods the next tension required for production (5).

The textile material, which had previously been used as a double-layer flat tube product, was Deflection roller (6) and a frusto-conical inlet wide opener frame (8) on the cylindrical Inlet body (12) and the opened goods (7) are transported over it cylinder-like inlet wide opener frame (8) and the cylindrical inlet body (12) are connected with each other. At the infeed body, tapering bodies (9) arranged. Support or transport rollers (10) lie against these bodies from the outside. which has a profile adapted to the shape of the tapered body both the support in the balance as well as the transport of goods are guaranteed.

The entire inlet body is in the idle state on four pairs of rollers (9 and 10), which are fixed to the frame (11) on the circumference of the inlet body. The pairs of rollers (9 and 10) are 4-fold on the circumference at an angle of 90 degrees At this stage, the goods are given their complete circular shape for final processing
Depending on the required diameter, transport rollers can be adjusted inwards and outwards and can be adapted to any diameter. Between the insertion body and the guide body there is a space for the installation of knitted fabric guards on the outside or web controls for a straight course of the thread ), which is held in suspension by the inlet body through the connecting pieces (14). The guide body gives the goods their final, circular shape and a further final tension depending on the type of fabric and diameter size before the process. This means that the final circumferential tension required and determined for machining has been reached. However, the empirical operating values should be specified here. The technology (Figs. 15-16-17) clearly shows the technology - and roughing tables etc.) are located in the housings intended for this purpose and in the interior of the guide body. Storage with minimal manual, usually sufficient adjustment options for these counterparts takes place in the housing .Alternatively, the counterparts can be spread via a central support inside the tubular goods and can be set separately for each level using guide elements. The required production tension for the goods is ensured on the one hand by the fixed diameter of the cylindrical guide body (16) and on the other hand by the spreading adjustment device.

By gently clamping the goods through the pair of rollers (9 and 10) and Surface adhesion of the material to the coated guide body is shifting of the textile material, thus the possible sources of error due to sideways sliding, locked out. By means of aggregate technology (15) depending on the diameter of the goods horizontal or vertical positioning is adjustable, takes place in the form described textile process. After the textile processing process on the guide body, the Goods (17) again over a wide opener frame (19) a tension regulating idlers supplied with rotary tensioner (21 and 22) to the pair of goods discharge puller rollers (23) The machine can also have units (dryers) etc. installed in the intermediate space (20) become. The goods speed at the inlet (4) and outlet (23) is normal However, regulation of the speed of goods according to requirements is in the form of Pre- and post-race possible.
