Process for the production of an active ingredient on circular knitting and knitting machines, as well as Machine for performing this procedure.

The invention relates to a method for producing a Active ingredient on circular knitting and knitting machines for stockings, especially on two-, four- or multi-system circular knitting machines and knitting machines with two, four or more feed stations, usually in the same around the needle cylinder Are spaced from each other.

The present invention thus relates to a method of manufacturing a for example perforated and knitwear that looks like an inlay on circular knitted fabrics and

B09818 / 0773

-Knitting machines, e.g. for the production of stockings, Here the invention relates in particular to a Such a process, which is carried out on Rundvd rl ·: - and knitting machines for men's or men's stockings or socks with "two or more thread feed stations can be exercised.

The invention also relates to a machine for carrying out this method.

In general, making inlaid knitwear involves making a fabric with guided stitches using threads of different parbs, in such a way that mesh areas are obtained, which are of different colors and which can be combined with one another in a suitable manner.

The usual processes for the production of inlay-like active substances, e.g. stockings for men and children, on the runa knitting and knitting machines here invariably provide that the machining with an alternating rotating movement of the needle cylinder for the individual colored zones is carried out, with a predetermined number of needles and a single one from pail to case Thread feed or a thread of a single color is used, while the other thread feeders are excluded (in

the Ans-steepness) remain.

It follows from this that the creation of a mesh product of this type with the "known methods" either because of the reciprocating movement of the needle cylinder or is also very slow because the zones with colored Stitches are made one at a time, i.e. one at a time.

The aim of the present invention is to provide a method and a machine for the manufacture of inlaid-like active ingredient with a reciprocating rotary motion of the bathing cylinder on circular knitting and knitting machines to create for men’s or children’s stockings or socks, with whose help all pad feed stations at the same time Fabrication and formation of stitches can be used by putting all available hadels on the cylinder of the. Machine used during each alternating stroke of the cylinder itself.

Another object of the present invention is to provide a method and a machine for the manufacture of marquetry To create active substances in which all different colored threads simultaneously "^ on certain needle sectors of the cylinder are inserted into the mesh, in this way a complete series of meshes either during the going stroke as well as during the return stroke of the back and forth

5098Ϊ8 / 0773

to generate forthcoming movement of the cylinder itself.

Another object of the present invention is to produce an active ingredient "in which all zones or sectors of different parbe are at the same extent, which corresponds to the cylinder's needle rim, and this for the purpose of creating meshes during all levels in both directions of the cylinder on the one hand and on the other hand at the same time, the working hours and consequently also the manufacturing costs to be reduced significantly.

For the above purpose, according to the invention, the new Process characterized in that it consists of the following steps:

a) the needle cylinder is actuated to carry out an alternating rotary movement at least via one Angle of 36o ° starting from a dead center or from Turning point of rotation;

b) threads of different colors are fed to all feed stations at the same time;

c) it is made unchangeable and for each feeding station and during all reciprocating strokes of the cylinder at least half of the number of! rebuke the cylinder is ineffective (transfer to healing) ;

509818/0773

d) it is left unchangeable and for each feeding station and during the entire reciprocating process Movement of the cylinder work the rest of the cable of the! Rebuke of the cylinder (transfer to the Setting);

e) one makes optionally active and / or inactive (inactive) at least a part of the above in the effective Position (on-position), each Feeding station opposite! Rebukes to a certain pattern with regard to the marquetry and get stakes;

f) one lets all rebukes of the cylinder work at the same time, those in so many consecutive bectors are subdivided by! censures as there are feeding stations are in such a way that each sector of! blame the thread fed to the corresponding feed station in Incorporated stitches.

A circular vdik and knitting machine to carry out the new process is characterized in that a pair of lock parts is attached to the rejection cylinder of the machine for each feed station is assigned, 'which are symmetrically arranged and inclined to one another in opposite directions, in order both during the outgoing stroke and during the decreasing stroke of the cylinder to act and to control this.

In Fig. 1 to 6 and 9 of the accompanying drawings, the reference numeral 1o indicates the needle cylinder of a circular knitting and knitting machine for the production of stockings, the four thread feed stations A 1, A ₂ , A 1, A, evenly distributed along the circumference / are assigned, each of which is fed with a thread 1, 2, 3, 4 in the usual way or with the aid of thread guides, which are not shown further, these threads 1, 2, 3, 4 having different colors. Each thread feed station A ₁ , Ap, A ^, A ^ is assigned a pattern drum 11, 12, 13, 14, which is provided with pins which are arranged according to a pattern in order to control a plurality of selector levers 15, which are on the teeth of the selectors 16 act on the cylinder 1o in order to move more or less strongly the needle carriers 17, which are assigned to the activation (setting) or the deactivation (opening) of the needles 18 for the formation of the loops.

According to the present invention, a pair of lock parts 19, 2o is provided for each stitch system corresponding to each thread feed A .., A _{2, A ^, A, according to FIG.} that they act on the needles 18 for the formation of the loops during the outward journey or during the return journey of the alternating movement of the cylinder 1o and control these needles 18. Similarly, there are also

509818/0773 _ _q _

For each mesh system a lock part 21, which engages the feet of the needle carrier 17, and a lock part 22, which engages the J ¹ UBen of the selectors 16, are provided, both ropes 21 and 22 are approximately triangular or have such a profile that they control the adjustment movement of these elements during all alternating or reciprocating movements of the cylinder.

In addition, each of the rocking levers 15, which of the Pattern drums 11, 12, 13, 14 are controlled to work on the teeth of the selectors 16 to act, two gate projections 23, 24, which are bent in opposite directions and according to Fig. 9 to the cylinder Io in an approximately tangential direction in order to access the above-mentioned selectors in each case during the stroke in one direction of the cylinder or during the return stroke in the opposite direction to act.

The machine constructed in this way is therefore suitable to process the threads of the four feed stations both during the stroke in one direction and during the Stroke in the opposite direction of the reciprocating motion of the cylinder. This back and forth movement takes place at least over a complete revolution or over 360 ° starting from a dead center M according to FIG. 1 up to this Dead center itself or vice versa.

509818/0773 - io -

Assuming this, it is found that the rounding and knitting machine for stockings is also provided with per se known thrust or thrust organs, which are also used by the Pattern drums are controlled to predetermined ladelselek-. to make gates on the cylinder ineffective or to transfer them to the exhibition depending on the respective requirements. The following now describes the method for achieving an inset or inlaid effect Knitted fabric according to the present invention in detail described.

The "method according to the invention provides the following steps:

a) the needle cylinder 1o is actuated to carry out an alternating rotary movement for at least 36o ° starting from the dead center M or it is allowed to rotate in the opposite direction carry out;

b) at the same time the differently colored threads 1, 2, 3, 4 are brought up to the corresponding pad feed stations A .. A ₂ , A ₇ , A.;

c) one makes ineffective or excludes from work (transfer to the off position) - unchangeable for each feeding station and during all alternating movements of the cylinder 1o with reference to the dead center H - at least half of the

509818/0773 - 11 -

!! adorn the cylinder, accordingly (opposite) " half of the circumference of the respective feeder ti ngs stat ion itself adjacent cylinder;

d) one leaves - unchangeable for each feed station and during all the reciprocating movements of the cylinder 1 o with respect to the dead center M - the other Half of the! Reproaches of the cylinder work or be effective (transfer to the on position) in the Half that corresponds to the circumference half that of the respective Feed station is diametrically opposite;

e) a fabric with a pattern corresponding to that programmed with the machine's pattern drums has been to achieve, leave at least a portion of those in working position, everyone Feed station opposite threads are effective and / or ineffective or in the entry and / or exhibition pass over;

f) all needles of the cylinder are allowed to work at the same time, which is divided into so many consecutive sectors are available as feed stations for the thread are such that each row of stitches has as many differently colored sections as there are Number of threads fed simultaneously.

The reciprocating rotary movement of the needle cylinder and the simultaneous feeding of threads to all feeding stations is found in a "known manner" as in the usual circular knitting or knitting machines for stockings instead.

The transfer to the off position of one half of the! Rebukes on Cylinder with respect to each thread feed station is made with the help of the pattern drum that of the corresponding feed station opposite, and caused by the mediation of a suitable number of exclusion levers, their training and their Features correspond to those of the selector lever 15 for the pattern. This disabling the needles for each half of the circumference of the cylinder 1o happens with respect to each thread feed Step by step, to the extent that the needles themselves are guided past the sample drum of the thread feed station be, and this soxvohl during the forward stroke as well as during the return stroke of the cylinder, such that for each individual thread feed station the threads that are effective are always those that are 13o circumference of the cylinder opposite that of the feeding station with respect to the position of the cylinder is adjacent at dead point M. Obvious is the exclusion of needles from work corresponding to each thread feeding station instantaneous and confined to the feed station itself; in fact, those of a feeding station can

Complaints on their part are excluded from work or activated opposite to the subsequent feed station. In the scheme according to Pig. 1 shows the sectors S ₁ , S ₂ , S *, S ^ of active or activatable threads in the respective feed stations A ₁ , A ₂ , A-, Αλ, each corresponding to a circumference. Like from Pig. 1, the needle sector S ₁ , which corresponds to the feed station A ₁ or is opposite, is assigned to the circumferential half of the cylinder which is opposite to that associated with the feed station in question with reference to the. Location of the cylinder at the dead center M of its reciprocating movement is adjacent. The needle sections S ₂ , S ^, S, for their part, are _{compared with the corresponding feeds A 2} , A ~, A.

In Pig. 4 shows the same scheme in a linear development, with full lines showing the sector of the inactive (in the off position) needles and broken lines showing the sectors of the active needles or needles to be activated at each feed station A ₁ , A ₂ , A , · A, are shown. With regard to the particular selection or selection of the needles that can be activated and the needles that have been rendered ineffective, it follows that at the dead point M of the reciprocating movement of the cylinder, no needle that could be opposite any feed is active or effective. Like Pig. 1 can realize so if the cylinder is in the dead center of its reciprocating movement and is about a hub

509818/0773

to begin or reverse a movement, the needle sectors that can be made operative, all of the feed stations concerned arranged opposite while in the. the needles from the areas adjacent to these feeds Work excluded.-are (in off position). In this way there can be no stitching at any of the feed stations during the reversal of the movement of the cylinder.

The sectors of the active or activatable needles S,., S ₂ , S, S ^ are gradually fed with the thread of the corresponding feed stations A ₁ , Ag »A ^, A ^ as the needles themselves pass these feed stations . Essentially, the beginning of the loop formation takes place when the cylinder has executed at least one fourth revolution from the beginning of each stroke, see FIG. 1, ie when the first active or activatable needles pass the corresponding feed stations.

The needles of sectors S ₁ , S ₂ , S ^, S, can in turn be excluded and / or activated for the execution of a knitted fabric with a predetermined pattern programmed on the pattern drums 11, 12, 13, 14.

The above selection takes place with the aid of the selector lever 15 controlled by the sample drums and two arms 23,24 own that on the selectors during the outgoing stroke

509818/0773

and act accordingly during the return stroke of the needle cylinder. The selection takes place in the usual way with indentations or reductions and elevations or elevations in in such a way that the number of needles for the formation of the loops is increased or decreased, but for all! "all" in such a way that with each stroke of the cylinder a complete Row of meshes is generated.

The pairs of cam members 19, 2o acting on the needles opposite each feed station make it possible to raise the needles for receiving the threads and to work them into the loops of these I ¹ ad s during all the reciprocating strokes of the cylinder for continuous formation of knitted fabric.

In? Ig. 3 and 8 of the drawing is an example of an inlaid type looking fabric with inserts of four colors 1, 2, 3, 4 shown, according to the present method and below Use of a circular knitting and knitting machine with four feed stations can be achieved, which is provided with the above-described enclosed devices. The achievable pattern can and the inlaid-like zones can be combined as desired by using the pattern drums in suitably the processing sections or individual work operations combined.

In Figs. 5 and 6 there is shown the scheme of the activated needle for the production, for example, of a complete row R of the inlaid knitted fabric, as is done in Pig. 3 and 8 is shown. The needles activated (in the process of being set) are the whole. Perimeter of the cylinder assigned, and they are divided into sectors C ₁ , C ₂ , C *, C, which are almost the same size and which are assigned to the four feed stations for the different colored threads. In particular, the sewing sector 0 ... _{will pick up the thread A 1 of} the feed station A ₁ , and at the same time the needle sectors Cp, C ^, C, will pick up the threads at the corresponding feed stations A ₂ , A ^, A. As soon as the formation of a single section of the course has been completed, the other sections are also finished in such a way that the complete course R is obtained, which is formed from four sections or zones 1, 2, 3, 4 of different colors. Proceed in this way for all courses, increasing the number of needles in some sectors and decreasing the number of needles in other sectors, as shown in Fig. 7 of the accompanying drawing, in which the diagram of the The action of the needles to form a row R is shown. In this Fig. 7 it is in fact possible to note that, for example, the number of needles of the sectors C ₁ and C ₅ ^{1 is} greater than the corresponding sectors of the course R (Fig. 5), while the number of needles of the Sectors C ₂ 'and C ₄ ^{1 is} smaller than that of the corresponding sectors for the formation of the row R.

On every pall, everyone takes criticism of the cylinder for incorporating it in stitches of the thread fed to the four feed stations in order to always and invariably complete courses resulting from the successive expansion of the row sections of different colors, respectively be generated. These course sections of different colors are obviously connected to one another so that a continuous, uninterrupted knitted fabric is produced and obtained in which a prescribed pattern is periodic repeatedly as shown in FIG.

The connection zones between the above sections can be a Any shape, perforations, bevel dislocations, any Alignment with each other, etc. have, which is achieved by a suitable and known programming of the work controlled by the sample drums.

In the above description, particular reference is made to a circular knitting machine with four systems or feeders. management stations, it is however readily clear that the above-described procedure can also be used for machines with less or can be used with more feeds, only the concept must be retained unchanged, that double lock parts for the control of the blame and double tax means for the the selection levers or selectors for the preparation of knitted fabrics be provided throughout the reciprocating movements of the cylinder.

In addition, it is possible to produce goods with a number of loads of different colors that are greater than the number of Infeed stations or systems, simply by calling the at any or all of the infeed stations each or from case to case in the stitch incorporated thread with at least one other thread exchanges with the help the normal change of the thread guide, as it takes place and occurs on the usual machines. .

Finally, the machine can also be provided with means that work together with the sample drum for the purpose of and the sequence of the patterns regardless of the To vary or change the rotation of the drum itself.

In particular for the above reasons, the invention according to the present application allows an efficient production of inlay-like looking knitted goods with inserts on circular knitting and knitting machines for the production of stockings with a high Production efficiency and with such characteristics that the products are also of high quality from an aesthetic point of view are.
