Description

Circular knitting method and loom for making

  knitted fabrics containing inserted fur threads.

  The invention relates to a method for manufacturing knitted fabrics, in particular those containing fibers incorporated by combing, on circular knitting machines, in

  which at least one fur thread is inserted,

  ment according to a drawing, in a basic knitted fabric made with at least one basic thread by the fact that one makes go out, on

  at least one drop, selected knitting instruments

  that the fur thread is placed in front of them and that this thread is then formed in loops, towards the center of the loom and around the anterior sides of the selected knitting instruments, by means of plates

  which are pushed from an external position into a posi-

  inner part, so that the parts of the wire

  fur seized by the plates, upon exit re-

  following delay of unselected knitting instruments,

  come behind them.

  The invention also relates to a circular knitting loom.

  milk for making knitted fabrics, especially those containing fibers incorporated by combing; in a basic knit fabricated with at least one basic thread, at least one fur thread is inserted, possibly according to a drawing; the loom has a needle cylinder

  carrying the knitting instruments, a crown

  tines with nose plates and at least one fall

  which includes an insert for the furnace wire

  rure, an insert for the basic thread, a ser-

  cylinder lock and a plate lock, the cylinder lock being made in such a way that unselected knitting instruments can be removed with

  lagging behind selected knitting instruments

  in the area of the fur thread insertion member, and the plate lock being made of

  so that the fur thread placed in front of the instruments

  selected knitting elements released is entered by the

  tines and is formed in loops towards the center of the mete

  tier, around the front sides of the trico-

  selected yarn, so that the parts of the fur thread seized by the plates during the delayed exit of the knitting instruments not selected, come

place behind these.

  Knitted fabrics with incorporated fur threads

  are also used as basic knits for fabrics

  knitted with fibers incorporated by combing, called artificial furs, by what can be made, using fur threads, very tight basic knits having a preselected stretch in the direction

  transverse, that is to say parallel to the rows of mail-

  (German patent DE-OS 28 04 068) In the manufacture of other fabrics, knitted, for example plain jerseys, also, it is possible, by the incorporation of fur yarns, to adapt the qualities of the fabrics to the intended use, or obtain specific processing possibilities

fabric.

  Knitted fabrics of this type are generally produced on standard circular knitting looms, using plates, which are used in a known manner to knock down and hang the stitches during the formation of the stitches and can be produced as it is. usual also in circular knitting machines for manufacturing knitted fabrics comprising fibers incorporated by combing

  (German patents DE-OS 28 17 130, 28 47 838).

  To incorporate the fur yarns, two methods are known in particular. One consists in bringing the fur yarn exclusively to work points or falls of the circular knitting loom provided for this purpose, by the fact that, on these falls , selected needles are

  lifted in picking position to grip the furnace wire-

  rure, and that they are then retracted On the other hand, it is possible according to the method of the aforementioned type (German patent DE-PS 21 63 89), using nose plates having two grooves arranged one above the 'other, and a beak above the upper groove, to lift the selected needles first at least in the picking position, on the other hand to leave the other needles in the passage position and to bring them out only with delay In doing so, the nose-plates pushed first into an internal position to hang the stitches of the basic thread, are gradually retracted into an external position, so that the fur thread can be placed in the needles' beaks selected outlets Then, the nose plates are pushed inwards so that their beaks grip the parts of the fur thread

  between the outgoing needles and form them into bou-

  keys to the center of the machine During the next exit

  te unselected needles, the fur thread is placed behind the back of these needles Finally, it is known, by analogously using the method cited last on circular knitting looms with normal plates, to advance d first all decks

  normal for the mesh fabric, and then

  continuation of the selected needles, then then to bring back all the stages, then to bring the weft thread so that it comes to be placed in front of the selected needles and in front of the grooves of the stages, then to advance again all the plates to form the fur thread in loops, and finally to bring out the unselected needles to arrange the thread

fur on their back.

  The procedures described are also used in the manufacture of knitted fabrics comprising fibers which are incorporated therein by combing (US Pat.

  United States of America Nos. 2,985,001 and 3,023,596).

  A disadvantage of these methods is that for

  incorporate the fur threads, or even complete scraps

  your are eliminated for the production of the fabric, or else the width of the fall must be enlarged because of the particular order of the plates and the needles, which reduces the number of possible falls on a given cylinder periphery, and therefore reduces production capacity. The object of the invention is to carry out the incorporation of fur yarns, with reliable attachment of the stitches of the basic yarn, without appreciably enlarging the width of the scraps. This object is achieved with regard to the method by the fact that at least part of the plates is advanced with delay with respect to the usual hooking movement and that the fur thread is placed in front so that it is seized by the turntables - which were advanced late

and that it's formed in loops.

  With regard to the circular knitting machine used to implement the method, the object of the invention is achieved in that the platinum lock has a portion serving to advance with delay at least a part of the platens and that the inserter for the fur yarn is arranged so that it is

  seized by the plates released with delay.

  The advantages of the invention are that for

  the insertion of the fur thread, it only requires a

  delayed attachment of at least part of the boards

  tines Because of this, the delayed release of knitting instruments passing under the loops of fur yarn may

  take place very shortly after the release of the instruments

  selected knitting elements and the insert of the fur yarn can be placed outside the area of the knitting instruments taken out.

  much of the deterioration of trico- instruments

  or caused by them so that the invention ensures reliable insertion of the fur yarn although

  the fall has only been negligibly widened.

  vention is particularly advantageous on circular knitting looms for manufacturing knitted fabrics comprising fibers incorporated by combing, given

  that, in such trades, the width of the fall is nota-

  considerably larger than on other circular knitting machines due to the insertion of the fibers forming the

  hair, and for this reason an additional increase

  keep the width of the fall to insert the fur threads or use scraps to insert the threads

  fur had a particularly disadvantageous impact

  tagger on the performance of such trades.

  The invention will be clearly understood on reading the description

  me to the invention; and Figures 9 to ll are sections through a circular knitting machine along lines IX-IX to XI-XI of the

figure 8.

  According to FIG. 1, a circular knitting machine for manufacturing a knitted fabric 1 with inserted fibers comprises a base 2, a needle cylinder 4 equipped with

  knitting implements, for example tri-needle

  rate 3 in the form of valve needles, and rotatably mounted

  tion and a plate crown 6 fitted with plates 5.

  Knitting needles 3 and platens 5 are ordered

  des in the usual way by cam elements, and on the periphery of the needle cylinder 4 are arranged at intervals several falls with at least one drawing device by means of which the knitting needles 3 are selected according to the drawing to insert the thread fur and / or to take or not to take

fibers.

  Each fall is also provided with a feeding device.

  fiber statement 8 which serves to bring to the needles selected to take the fibers, fibers having

  a particular characteristic, for example color.

  Each feed device 8 consists, for example of a drum 9 provided with a spike packing, to which the fibers are brought in the form of a wick using a pair of feed rollers 11 , and by a picking or combing roller 12 provided

  a pimple coating, by means of which the fibers pre-

  lifted on the drum 9 are presented to the needles

  knit selected to receive the fibers.

  A drive 13 of the feed rollers 11 is controlled using a control device 14 so

  there are always as many fibers transferred from the tam-

  bour 9 with a combing roller as required by the drawing.

  The normal plate 5 shown enlarged in FIG. 2 has a heel 15 intended to cooperate with cams of needles, a nose 16 forming a groove 17 and a felling edge 18, and it is used in a known manner to break down the meshes and to prevent the mesh fabric 1 from rising during the formation of the meshes In addition, such a plate also comprises a control edge 19 between the felling edge 18 and the heel 15, control edge whose

  height corresponds to the height of the heel 15 and the function of which

tion will be explained later.

  Circular knitting looms of the type described are known for example from the German patent DE-PS 1 202 509 and from the German patents DE-OS 21 15 721,

  23 43 886 and 25 24 491, to which we will refer exclusively-

lie here.

  FIG. 3 represents a mesh fabric comprising

  fibers inserted by combing and fur threads

  The mesh fabric first has meshes which are arranged in rows 20 to 23 and in columns of mesh 24 to 29 and are constituted respectively by a basic wire 30 to 33 In the meshes of columns 24 to 26

  are introduced by combing bundles of fibers 34 sup-

  additional by means of the feeders 8, while the meshes of the columns 27 to 29 do not include these bundles of fibers and are maintained as they are,

  for example by the fact that in the circular knitting loom

  as shown in Figure 1, the knitting needles are

  ciées to the columns of meshes 27 to 29 are not selected-

  born to take fibers, but only to knit,

  or by the fact that we use a circular knitting loom

  cular in which the feeding devices 8 which are missing on some falls or on all falls are

see in Figure 1.

  In addition, in each row of stitches 20 to 23 of the knitted fabric according to FIG. 3 is inserted a fur thread at 38 forming a corrugation and represented by a strong line; this thread is inserted on the anterior side of the columns of mesh 24, 26 and 28, while, on the columns of

  intermediate meshes 25, 27 and 29, it comes in the form

  floated yarn core Mesh fabrics of this type are used

  naked (German patent DE-OS 28 04 068).

  The modifications to the circular knitting looms proposed according to the invention, in particular to a loom according to FIG. 1, in order to allow the insertion of the fur yarns in a knitted fabric according to FIG. 3 without significant loss of yield, will be described below

  with reference to Figures 4 to 6 To facilitate understanding

  gripping, we will not describe the parts that cause

  in known manner the insertion of fibers by combing.

  A circular knitting loom according to the invention is characterized

  térise in that selected turntables are made in the form of beak turntables Such beak turntables are known in many forms for manufacturing mesh fabrics having inserted fur threads (for example German patent DE-PS 21 63 89) According to the embodiment of Figure 4, such a nose plate 40 comprises on the one hand, as usual, a heel 41, a nose 42, a groove 43 and a felling edge 44, but in addition a beak 45 placed above the nose 42 which forms a second groove 46 for receiving the fur yarn

  in addition, the nose plate 40 is provided with a control edge

  of 47 which, in comparison with the normal plate of FIG. 2, is at a markedly greater distance from the heel 41 In the embodiment of FIG. 5, a plate with spout 50 is provided on the one hand, as habit, a heel 51, a nose 52, a groove 53 and a felling edge 54, and in addition, on the other hand, a beak 55 located above the nose 52, which forms a second groove 56 for receiving a fur thread In addition, the nose plate 50

  has a control edge 57 which, compared to the plati

  nes normal of Figure 2, is at a greater distance from the heel 51 The nose plates 40.50 are used in the ring gear 6 shown in Figure 1, alternating with the normal plates 5, for example in

  1: 1 ratio or in the 1: 1 sequence.

  FIG. 6 represents, seen one above the other and in developed projection, the arrangements of locks of a chute for fur yarns according to the invention; the lower cylinder lock, shown in developed projection, controls the hands 3, the upper platen lock, shown without its appearance in an arc of a circle, on the other hand controls the plates 5 and 40, or 50, the needles 3 and the

  5,40,50 plates moving in the direction of arrow v.

  By fall for fur yarn, here is meant a fall which, in addition to the normal basic yarn guide and the possible fiber feeding station, also comprises a member

  insert to insert a fur thread in addition.

  The lower cylinder lock has an air path

  guilles 61 which first has an ascending exit ramp

  Dante 62 to which a re-entry ramp is connected

  ash 64, to which the corresponding parts are connected

  of the following fall The knitting needles 3 alternately comprise long heels 65 and short heels 66 (see FIGS. 9 and 10); the needles fitted with short heels 66 are shown in black on

  Figure 6 The lower boundary of the road

  guilles 61 is formed by a cam of needles 67 which

  carries a recess 68 shown hatched in the area of the outlet ramp 62 and has substantially the shape of a parallelogram and which has, perpendicular to the plane of the drawing, a depth greater than the length of the

  short heels 66, but shorter than the length of the ta-

  long lengths 65 Consequently, the outlet part 69 of the needle cam 67 adjacent to the outlet ramp 62 does not

  can only act on long heels 65 and lift them.

  On the other hand, the short heels 66 are not grasped by this outlet part 69 and continue to circulate along the lower delimitation of the recess 68, first in the circulation position until they arrive on a exit part 70 which delimits the recess 68 on the left in FIG. 6 and constitutes an exit ramp similar to the exit ramp 62 This exit part 70 lifts the short heels 66 until they reach

  the straight portion 63 of the needle path 61 and conti-

  strip their way into it with long heels 65.

  The purpose of the recess 68 is to provide two outlet parts 69 and 70 distant in the peripheral direction of the needle cylinder and to cause the needles provided with short heels to come out with a delay, that is to say later than

the other needles.

  Instead of selecting the needles by short and long heels, it could be done according to the path of needles 61 by means of heels arranged in a different way or additional heels, or by means of known selection devices, so that the knitting instruments

  selected are output based on the layout of the par-

  tie exit 69, on the other hand that the knitting instruments not selected are taken out according to the layout of

the exit 70 section.

  As further indicated in FIG. 6, an insertion member 71 for the fur thread is associated with the ramp 62 so that a fur thread is placed in front of the long-heeled needles 65 already fully or partially extended out, while the beaks of the short heel needles 66 not yet out or not yet out above the nose plates 16, 42, 52 do not receive the fur thread, but pass under it In addition, a body insertion of base thread 72 is associated with the re-entry ramp 64 so that all the needles 3 can receive a thread after passing the straight portion 63 Between the insertion member 71 and

  the insertion member 72, it is also possible to have a drum

  comb of comb 12 (Figure 1) The lower cylinder lock shown in Figure 6 is thus a means for bringing out knitting instruments to place the fur yarn in front of them and for delaying out knitting instruments not selected for

  place the fur thread behind these.

  The upper plate lock comprises, according to FIG. 6, a plate path 73 which is formed by two cam elements 74 and 75 and is designed to receive the heels 15 of the normal plates 5, and the heels 41 of the nose plates 40; in this case, the heels 15 and 41 have - substantially the same shape and the plates 5 and 40 are used

  preferably in alternation, that is to say in the sequence 1: 1.

  The arrangement is designed such that, in the direction of rotation of the needle cylinder, a nose plate is each time followed by a short heel needle 66 and each plate 5 is followed by a long heel needle 65, although other arrangements are also possible. As can also be seen in FIG. 6, the heels 41 of the nose plates 40, during movement from right to left,

  are first moved away from the needle cylinder 4, that is to say

  say radially outward, by a portion 76 of the outer edge of the cam 75, then supported by a portion 77 of the cam 74 and again pushed radially inward However, the heels 15 of the plates normal 5 are, of course, also brought outwardly by the portion 76 of the cam 75 Then, the control edges 19 of the normal plates 5 however reach the area of action of a portion 78 of the inner edge of the cam 75 rising inwards, so that their heels 15 are lifted by the internal edge of the cam 74 and do not reach the zone of action of the portion 77 thereof, as indicated on FIG. 6 for a normal plate 79 The outer edge of the cam 75 has in this zone a recess large enough to prevent the heel 15 from mounting on the cam 75 and prevents control by means of the control edge 79

  and of the portion 78 The portion 77 is here arranged behind

  the portion 78 in the direction of the arrow v so

  that all 4 È beak stages are advanced with a re-

  late compared to normal decks 5 in their position

radially inner.

  The control edges 47 of the nose plates 40 cannot act alternately with the portion 78, since their distance from the associated heel 41 is greater than

  the distance between the control edge 19 and the heel 15.

  The portions 77 and 78 are first followed in the direction of the arrow v by a substantially straight portion 80 of the plate path 73 corresponding to the portion 63, and a portion 76 is again connected to the portion 80. the portions 77,78 and the portion 80, and the following portion 76, a portion acting for example on the heels 15,41 of all the plates 5,40, which

  portion pulls all the plates radially outwards

  laughing in an intermediate position.

  Due to this configuration of the turntable lock,

  the plates 5 and the nose plates 40 can be moved

  created differently, although they have their heels

  , and 41 in the same place It is thus possible to order

  der the plates 5 in the optimal way for the formation of meshes, and on the other hand to order the plates with beak

  optimally for the insertion of the fur thread.

  The command is the same when using the turntables

  spout 50 instead of spout plates 40 The operating mode

  The operation of the method and the circular knitting loom of the invention, according to FIG. 6, is as follows: due to the distribution of needles into needles with long heel 65 and short heel 66, for example in the ratio 1: 1 , the long heel needles 65 alone are first exited in the region of the recess 68, while

  that the short heel 66 needles enter the recess

  ment 68 in passage position and only exited by

the exit 70 section.

  Thanks to the precise adjustment of an insertion member 71 for the fur yarn, it is obtained that this is placed each

  times on the body of the long heel needles 65 which comes

  come out and open up and as a result these

  guilles continuing to exit, certainly slides under the valve of these, but remains placed on their anterior side; on the other hand, the short heel needles 66 pass under the fur thread and-are only taken out afterwards. It follows that the fur thread comes to be placed on the anterior side of the long heel needles 65 and on the posterior side of the needles with short heel 66 and is thus placed while undulating

  alternately in front of and behind the needles.

  When the needles continue to circulate, they first arrive in the area of the combing drum 12 shown only in FIG. 1, to take fibers there in the usual manner, then in the area of the thread insertion member. base 72 which places a base thread in their beaks, and then in the area of the withdrawal ramp 64, which brings in all the needles 3 in order to form stitches in the usual manner with the base thread The fibers and the thread fur are inserted simultaneously in the knit

  as shown in Figure 3.

  The placement of the fur thread on the back of the short heel needles 66 is aided by the use of the nose plates 40 (or 50), which are used in the 1: 1 ratio in the crown with plates 6, in the manner following: According to FIG. 6, the normal plates 5 as well as the nose plates 40, 50, are moved away from the needle cylinder 4, towards the outside, in the usual manner, by the portion 76 of the plate lock acting on their

  heels 15 or 41.51, in order to form the Pen-

  during the formation of the meshes in the following fall, the control edges 19 of the normal plates 5 arrive

  first in the portion 78 area, so that the plates

  normal tines 5 are advanced towards the axis of the

  needle cylinder and that with their grooves 17, they ac-

  hook the stitches previously formed When going out

  next tie, in particular long heel needles 65, the normal plates 5 thereby fulfill their function

  usual and prevent the fabric from rising with the needles

  This is shown in Figure 7 as an example

  for two normal plates 82 and 83 and a three-way tool

floor 84 with long heel.

  Since the control edges 47,57 of the noseplates 40.50 are at an appropriate distance from their heels 41.51 and therefore cannot have any interaction with the portion 78, the noseplates 40 remain 'first in the retracted position, as shown in Figure 7 for a plate with beak 85 During the movement of normal plates 5, a fur thread 86 is brought above the noses 42,52, however in front of the beaks 45 , 55

  nose plates by means of the insertion member 71. The fur thread 86 is brought so high and so far outside

  that this thread 86 does not obstruct the opening of the valves of the needles provided with a long heel 65, for example of the needle 84 At the same time as the needles with long heel 65 are raised, the nose plates are pushed forward towards the axis of the needle cylinder, given that their heels 41, 51 now arrive in the area of the portion 77 of the lock of platinums, as represented in FIG. 7 by a plate with beak 87 Therefore, the thread of fur 86 arrives in their upper grooves 46 and is advanced in the shape of a triangle, as shown in FIG. 7, between the long heel needles 65 already out, for example the needle 84 and a needle 88, in the direction of the axis of the needle cylinder At this instant, the short heel needles 66, for example a needle 89, have already reached the exit part 70 of the cylinder lock, so that when they ascend they arrive in the delimited triangular zone by the fur thread 86 and that this thread 86 is arranged so on their back Finally, fibers are incorporated by combing in a known manner not shown in Figure 7 and a basic thread is

  Previously brought all the decks, especially the

  beaked tines, can be pulled outwards by means

  of the portion 81 in an intermediate position for ter-

  thus undermining the formation of the meshes and slackening the wire

  of fur 86, as shown in FIG. 7 for a plate

  beaker 91 For the rest, the felling edges 44.54 and the hooking grooves 43.53 of the beaker plates 40.50 participate in the formation of the meshes with the basic wire in a manner analogous to the mode operating edges

  felling 18 and hooking grooves 17 of the standard plates

males 5.

  To continue to explain the described mode of operation of the circular knitting loom, we now refer

in Figures 8 to 11.

  FIG. 8 schematically represents a top view of part of the crown of needles and plates; the needles 3 with long heel-65 are represented in clear and the needles 3 with short heel 66 are represented in black The insertion member 71 represented in FIG. 7 as well as the fur thread 86 brought by it are visible on the drawing The movement of the hands and the stages is carried out as for figure 7 according to an arrow W The parts of the stages represented hatched or in black on the top view result from the side view represented

  bottom right on Figure 8.

  Figures 9 to 11 show sections through the metal.

  circular knitting tier according to the invention, along lines IX-IX to XI-XI of Figure 7 and show the relative position of the hands and the stages at different

  places of the crown of hands and plates.

  According to FIG. 8, a needle 92 with a long heel is located

  precisely at the place where the fur thread 86 is grasped.

  The section in FIG. 9 shows that this needle 92 is in the process of mounting and that its valve is already open In

  its beak is hooked the mesh formed at the fall before-

  tooth forming part of the mesh fabric 93 which is pulled in a known manner The long heel 65 is guided by the extended part 69 For reasons of clarity, the nose plate

  according to the needle 92 has been omitted in FIG. 8.

  The normal plate 94 immediately preceding the needle

  92 is, according to FIG. 8, in a light position

  rement radially inwardly pushed, so that the mesh 93 is in known manner in its groove 17 and can not go up The needles and plates located before the needle 92, and in front of the normal plate 94 in the direction of rotation, have been omitted on

  Figures 9 to it for reasons of clarity.

  Before the normal plate 94 there is, according to FIGS. 8 and 10, a needle 95 with a short heel, and before it a nose plate 96 according to FIGS. 4 or 5 The needle 95 has not yet started to rise because its heel 66 is too short to be able to mount on the outlet part 69 Consequently, the head of the needle 95 is still below the upper edge of the nose of platinum 42 On the other hand, the nose plate 96 lying in front of it has been almost

  fully advanced towards the cylinder axis at ai-

  guilles For this reason, the fur thread 86, under which the beak plate 85 is first passed at the location of the insertion member 71, was however placed behind the latter, during the advance of the needle-nose plate 96, and in the groove 46 thereof, then pushed forward in the direction of the axis of the needle cylinder far enough to be placed securely in the back of the next needle 95 For this reason, the fur thread 86 is already pushed by the nose plate 96 far enough towards the center of the loom so that, when the needle 95 comes out which will only take place after, with delay, it comes place itself securely behind this needle, and that needle 95 rises securely from the loop of fur yarn formed

by the plate 96.

  According to Figures 8 and 11, it is located before the plate

  with beak 96 a needle 97 with long heel 65 and a normal plate

  male 98 The needle 97 is fully extended because its heel 65 is already sliding on the straight portion 63 of the path

  of needles, and plate 98 is also fully advanced

  We also see in Figures 8 and 1h that the fur thread 86 is in front of the needle 97 below its valve because it was placed in front of the needle 97 to

  the place with which the needle 92 is associated in FIG. 8.

  The invention is not limited to the examples described, but many variations can be made to it.

  instead of flapper needles other knitting needles

* ter or other knitting aids

  tubular or sliding guilles, hooks, special needles or the like In addition, the fur thread need not be placed in front of and behind the needles in the 1: 1 ratio. Any which placement by appropriate use of short heel needles and long heel needles and / or turntables and beak turntables In addition, it is not necessary to provide on each fall an insertion member for a wire

  fur, since it is often common and desirable

  ty to introduce the fur thread only both,

  three or four rows of stitches.

  tion 71, it does not matter, as shown in FIGS. 6 to 8, that the fur thread 86 is already gripped by the long heel needles if these are still at any point on the output part 69 or already on the rectilinear portion 63 What is important is that these needles have already come out far enough, during the placement of the fur thread so that, during the next advance of the nose plates, the latter cannot slide on the needle noses and reach the rear side of the needles Similarly, the exact position of the outlet part 70 is indifferent You only need to be sure that the short-heeled needles are running under

  the weft thread when they pass the insertion member 71.

  It is the same for the position of the portions 76, 77 and 78 of the plate lock provided for advancing or withdrawing the normal plates 5, and the nose plates 40, 50, since it is only necessary to have l '' assurance that the nose plates come out with sufficient delay compared to normal plates so that they pass safely under the fur thread, and that during the next advance of the nose plates, it will surely be gripped by their mouthpieces

45.55.

  Instead of the described combination of normal decks

251285 X

  and with turntables, we can also foresee

  of the normal plates according to FIG. 2 In this case, for example, all the normal plates will advance with delay relative to the usual gripping movement for example using the portion 77 of FIG. 7, and on the other hand , the fur threads will be brought so that, when advancing the normal plates, they are placed in their usual grooves In this case, when the selected needles exit, it is the other needles that prevent the fabric from meshes to go up In this embodiment, only one advance with delay

  plates are sufficient to safely place the fur thread.

  It is also possible to provide two-part plates with normal movable or pivoting parts and beak parts. The normal part could have a

  shape corresponding to the plate of Figure 2; by con-

  tre, the beak part could have a shape corresponding to the plate of FIG. 4 or of FIG. 5; however, the grooves 43,53 and the felling edges 44,54 can be eliminated. In each groove of the plate crown, the two parts of the plate could be placed next to each other so that they can move and control them with an arrangement of locks corresponding to the lock of plates of FIG. 6 The advantage is that, in comparison with the number of plates of FIG. 6,

  we have twice as many normal parts and

  instead of being arranged in the crown

  turntables, the turntable parts could also be

  be in or near the needle cylinder grooves

  or above knitting instruments 3, and they can

can also be pivoted.

  Instead of providing different distances between the control edge 19 and the heel 15 of the normal plate, or between the control edge 47, 57 and the heel 41, -51 of the nose plate, the heels of the two groups of plates could also have different heights and be controlled in a known manner by cams of different heights Similarly, the arrangement of the heels at two different locations and their guidance on two paths of the

  plate lock is possible Other forms of plate

  beak tines are also possible Among the embodiments shown in the drawing, the beak stage

  has the particular advantage that, compared to the pla-

  beak 40, because of its throat 56 located lower, it requires a shorter exit from the needle, -which is advantageous when using? valve needles of short length In addition, the nose 52 is significantly shorter than the nose 42, which makes it possible to reduce the stroke of the plates Finally, it is possible, contrary to FIGS. 4 and 5, to place the bottom of the groove higher 46.56 at a greater distance from the heel 41.51 than the bottom of the groove 43.53 This would have the advantage that, when advancing the noseplates 40.50, the mesh fabric is certainly hooked in the gorges 43.53 but is not as strongly stretched as it is depicted from

  exaggerated in Figure 7 for the nose plate 87.

  In addition, one can obtain the delayed exit of the needles

  selected with other means than-high heels

  different heights, for example with at least two heels

  arranged in different planes, or using a dis-

  selection positive that raises selected needles

according to exit 69.

  Finally, the invention is not limited to circular knitting machines for making knitted fabrics with fibers incorporated by combing, but it can also be used with circular knitting machines for knitted fabrics with a fleece of threads. blanket or binding, or on other circular knitting machines in which the fur yarns are inserted in a basic knit simply as effect yarn, for example as yarn with dyed buttons, or the like, which does not behaves

no fibers incorporated.
