Description

The present invention relates in the first place to a footwear

  you jersey formed by the transfer of the stitch (mesh openwork).

  It is known, in particular from Italian Patent No. 991 190 of

  the Applicant, to manufacture a sock of this type on a trico-

  a single-cylinder machine which has the particularity of having, in the slots of its cylindrical needle needle bed, normal needles with latches which alternate with special punches with a profiled point in order to be able to take a loop of mesh of a needle for the

  transfer to an adjacent needle. Controls and selectors

  properties make it possible to obtain the entire circumference of the

  you mesh effects of various kinds.

  In some cases, it is also desired to obtain color drawing effects on the same stitch transfer sock sock. These color drawing effects can be realized on

  parts of the single knit leg which are integrated in the design of

  appears in openwork knit, by embroidering on these simple mesh leg parts one or more colored threads that are superimposed on the thread of

  background. In this case, however, a supernatural

  which can not be performed on the circular loom for socks, but must be performed on an embroidery machine. In addition, the color drawing is related to the worked mesh design which must present

  appropriate features in simple stitches.

  The purpose of the present invention is therefore to make a mesh sock perforated by the transfer of the point with effect of color drawing on a portion of the leg made of mesh

  in which not only the color drawing can be

  seen on any part of the leg, regardless of the pattern of stitches made by transfer of the stitch, but in addition the sock

  can be entirely made on a monocylindrical loom for shoes

  setts, of known construction, avoiding a

  on an embroidery machine.

  This goal is achieved with the sock following the present

  vention, which is characterized in that its openwork mesh design is interrupted in a specific part of a single stitch area which exhibits color drawing effects produced by at least one different colored faded thread with respect to the strand , this zone having limited dimensions both in the circumferential direction and in the

  the meaning of the length of the leg of the sock.

  The advantage of the sock according to the invention is that the stitch-piercing stitches develop over the entire circumference of the sock itself and that the single-stitch area which interrupts the openwork stitch can

  to be carried out independently of the drawing thereof.

  Containing only one limited area of smooth or simple meshes with color drawing effects, there are no longer long

  floating yarn on the back of the sock, which could be

  when threading it.

  The sock according to the invention can be entirely made

  on a circular knitting and monocylindrical craft designed for the manufacture of socks, arranged for the production of stitched mesh socks by transfer of the point, for example the

  described in the aforementioned Italian Patent No. 991,190, with

  in the slots of the needle bed, alternating therewith, cams for controlling the upward and downward movement of said punches, and a system for selecting needles and punches to obtain the desired mesh pattern;

openwork by transfer of the point.

  In order to allow such a machine the manufacture of the

  sock according to the invention, said machine is provided with a device

  auxiliary device composed in substance of means capable of canceling, in a pre-established zone and during the manufacture of the leg of the sock, the selection made by said selection system for

  the formation of the pierced mesh by transfer of the point, of such

  that in said zone, simple meshes are formed; at least one wire guide for feeding the machine with one or more wires of

  color or colors other than that of the ground wire, a retractable cam

  table adapted to determine the lifting of the needles at a height sufficient to allow them to take said colored thread, a second selection system to select the needles which must seize the colored thread and to render inoperative the punches in said area simple mesh formation, and finally means for canceling the selection made by said second system

  of selection for all needles and punches which do not

  These means for canceling the selection made by the first system for selecting needles and punches are advantageously composed of additional selector levers of the system itself, capable of acting on heels. determined provided on the sub-needles to form

  drawings of both needles and punches belonging to the-

  said pre-established zone in which it is desired to form six-sieve meshes.

  In order to allow the manufacture of socks which have the single mesh zone alternatively in diametrically opposed portions of the leg, two groups are advantageously provided.

  diametrically opposed needles and punches, with sub-needles

  having heels at different levels, and two pairs of additional selector levers adapted to act respectively on said heels at different levels, these pairs of selector levers being controlled by a device whose work cycle has a duration

  corresponding to two work cycles of the machine. Thus, this provision

  tif is able to control, during a work cycle of the machine,

  a group of levers of said pair and, during the next cycle, the

group of levers.

  It is obvious that if, during the formation of the zone in identical meshes, one wishes to obtain effects of drawing in vanished wire,

  needles interested in this area should be able to be selected

  freely to carry out the color drawing, by the said

  cond system of selection, while the punches interested in the

  same area will have to be rendered inactive anyway.

  In addition, it should be emphasized that for the formation of the

  color drawing, should work only the needles which

  also to the formation of the part in simple stitches; for all the other needles and punches on which the selector levers of said second selection system can also act, this selection must be canceled, and this is obtained by providing on their sub-needles a particular heel on which is operated a selector lever corresponding of the second selection system during all the time of the formation of the simple mesh with color drawing. This last selector lever can be controlled by the phase drum of

the machine.

  In order to better understand the characteristics and benefits

  of the present invention, reference will now be made to the

  nexé, in which: FIGURE 1 schematically shows a sock made according to the present invention;

  As can be seen in Figure 1, sock A according to the

  present on a part B of his leg a zone C in which

  the mesh worked by transfer of the stitch (perforated mesh) is interrup-

  stinks and in which one has a simple mesh with effects of drawing in color. This zone C is limited both in the circumferential direction and in the longitudinal direction of the leg of the sock A. As will be seen later, the invention provides for making this sock entirely on a circular monocylindrical loom for socks. , and it is furthermore planned to manufacture alternately on this trade

  socks which have an area C on one side and also on the diagonal side

opposite of the jamibe.

  FIG. 2 shows on a greatly enlarged scale a piece of mesh fabric taken for example from part B of the sock A of FIG. 1. To the left of FIG. 2, the effect of knitted or perforated mesh is recognized by transfer of the dot with the mesh obtained with a background X, while on the right we see a part of the area C in single stitches with effects of color drawing obtained thanks to Y yarn whose color differs from that of the background wire X and who is

superimposed on this one (vanishing).

  To be able to produce such a sock on a circular monocylindrical loom for socks, it is necessary to use the

  means described below with reference to Figure 3.

  In the first place, the machine must be capable of

  meshwork worked or perforated by transfer of the point. For this purpose, it may comprise, for example, special punches 10 which, in the

  slots in the cylindrical needle bed (not shown),

  tarnish with pawl needles 11.

  The punches 10 comprise sub-needles 12 which are attached to them and which transmit the movement directly to them, both upwards and downwards, from the sub-needles of drawing 13

  and sub-needles 14. Each sub-needle 12 comprises only one tab.

  lon on which can act the cams 15, 16, 17 and 18 of the mechanism

  ism. The sub-needles 14 themselves each have a heel which can slide on the ring 19 of the mechanism and on which the cams 20, 21, 22, 23 and 24 can act. On the drawing sub-needles 13 can

  act instead of the selector levers of a first selection system

  tion, generally designated 25. When one of these levers is actuated and meets at its level a sub-needle bead 13,

  it is pressurized and presses the corre-

  14, which has the effect of preventing the heel of this

  It should be noted that in the rest position, as shown in FIG. 3, the under-needle 14 is separated from the sub-needle 12 by a distance "d" equal to the height. h "cams 20, 22 and 24; each movement executed by the sub-needle 14,

  amplitude equal to "h", therefore has no influence on the movement

punching 10.

  Each needle 11 comprises a sub-needle 26, a sub-needle

  drawing needle 27 and a sub-needle 28. Each needle 11 has a heel on which can act the cams 29 to 34 of the mechanism. On the drawing sub-needles 27 can act the selector levers of the selection system 25, and the sub-needles 28 slide with their heel on the ring 19 as the sub-needles 14 of the punches,

  and they are controlled like these by cams 20 to 24.

  The organs described so far and their mode of operation

  all of which are known per se, for example according to the Italian Pat. No. 991,190 of the Applicant, and they are capable of producing, with a background wire whose feeding is ensured in the form of a wire 35, a fabric tubular mesh stitch transfer work (mesh openwork). It is therefore unnecessary to describe in detail this mode of operation, which can be summarized as follows:

  When it is desired to ensure that the perfect stitch

  by a needle determined with the assistance of the cams 29, 30 and 31

  transferred to the neighboring needle, the underprivileged

  guille of drawing 27 of this particular needle and the sub-needle 13 of the punch next to the right (looking towards the outside of the

  cylindrical needle needle) are under pressure from a separate lever

  reader 25, so that these sub-needles allow the corresponding sub-needle 28 and 14 to mount on the cams 22, 23

  and 24, and that the needle and punch considered be trained

  respectively uphill and downhill by the cams 32 to 34 and 16 to 18,

  to execute the desired transfer of the point.

  On the other hand, when a particular needle must not yield

  mesh stitch to the neighboring needle, it is necessary to prevent this needle from

  the determined and the neighboring punch perform movements that

  carry the transfer of the point. This is achieved by preventing His sub-

  needle 28 and the sub-needle 14 of the adjacent punch can be mounted on the cam 22; their drawing sub-needles 27 and 13 respectively must therefore each have, at a certain identical level, a heel, and the corresponding selector lever of the selection system 25 must be placed in advance (thanks to a normal drawing drum, no

  represented), so as to press on said heel when the sub-components

  needles 27 and 13 pass in front of the selector lever. It is right to

  point out that the drum acts, via small

  cities or cards that can be inserted at will in pre-drilled holes

  seen on its circumference, on a certain group, designated in 25a, selector levers of the selection system 25. In this way, it is

  possible to produce a desired pattern of openwork meshes by trans-

  point, a drawing that can be recognized and represented

  as an example and illustration in Figure 1.

  To allow to interrupt on a given height B and a limited circumferential area C this mesh design

  or perforated, the present invention provides.

  in this area, the planned selection of needles and pointers

  In other words, it must be avoided that the needles and punches concerned by this zone can make the movements necessary to transfer the point,

  and make sure that these needles form a simple or fine mesh.

  This condition is obtained by providing, on the sub-needles of

  sin 27 and on the sub-needles 13 of this group of needles and punches, appropriate heels located at a fixed level (which differs for the needles from the level of the heels of the punches) and

  by providing in the selection system 25, at the corresponding levels

  examples (shown as examples 7 and 8 in Figure 3) of the

  appropriate selectors. If these levers are pushed during

  duration of the formation of the determined height zone B of the shoe

  However, it is obvious that throughout this period, program-

  meshwork will be canceled for all needles and

246581 3

  all punches relating to zone C whose formation will take place

  consequently in simple or fine meshes. The group of these two

  selector is designated 25b.

  However, a second group of two separate levers is

  readers designated 25c (for example at the levels indicated in 9 and 10), able to act on appropriate heels provided on the sub-needles 27 drawing and 13 respectively of a second group comprising a

  the same number of needles and punches found on the foun-

  in a zone diametrically opposed to the

  group of needles and punches interested in the formation of the-

  zone C. This arrangement makes it possible to form the simple mesh zone

  thin or thin in diametrically opposite parts of the leg of the socks. A suitable device, which will be described later with reference to FIGS. 4 and 5, makes it possible to control alternately during successive cycles of manufacture of the socks, the group of selector levers 25b and the other group of selector levers 25a, so that the single-stitch area is formed alternately

  on one side and the opposite side of successive socks.

  The device in question comprises a console 36 attached to the

  hosiery craft. In this console is mounted in rotation an armature

  37 which carries on one side a toothed wheel 38 in engagement with another toothed wheel (not shown) integral with the phase drum or distribution of the loom, while on the other side the shaft 37 carries a pinion 39. The latter meshes with a gear wheel 40 carried by

  a second shaft 41 also rotatably mounted in the bracket 36, parallel to

  This toothed wheel 40 is made integral with a drum 42 bearing in diametrically opposed and axially offset zones two cams 43 and 44 adapted to act respectively.

  on levers 45 and 46 which articulate on the console 36. These le-

  45, 46 may act in their turn on the respective souls of

  two flexible cables 47 and 48, one of which controls the two separate levers

  readers who make up group 25b and the other two levers

  readers which constitute the group 25c of the selection system 25.

  The transmission by the toothed wheels 38, 39, 40 is carried out so that the drum 42 performs a complete revolution for two

  complete turns of the drum of phase or distribution of the trade.

  Since, according to the invention, it is desired not only to interrupt in a given zone C the transfer-worked mesh

  point and form simple stitches in this area, but also

  in the same area C with single stitches drawing effects in

  color, the machine must have at least one feed point 50 -

  in wire having a color different from that of the ground wire provided by the wire guide 35. In addition, it is necessary to provide an additional cam 51

  able to act on the heel of the sub-needles 28 to lift the

  guilles on a height to enable them to grasp the wire provided by the feed point 50, and a second system of selector levers, generally designated 52, for the selection of the needles which must grasp said wire supplied by 50. The cam 51 is

  retractable so that it can be released from the heel of the under-

  guilles 28 in the parts of manufacture of the sock where

  does not form a single-stitched area with drawing effects in

their.

  It should be noted here that the selector levers

  form the group designated in 52a of the second selection system 52 a-

  lie on the heels of the drawing sub-needles 27 and 13 which

  at the levels corresponding to those to which the

  selector tongues which constitute the group 25a of the first selection system 25. To control the selector levers which form the group 52a, there is provided a normal drawing drum (not shown)

  Programmable thanks to removable dowels.

  It should also be emphasized that only the needles

  contribute to the formation of the single stitch area must inter-

  come into the formation of color drawing, and that these needles alone must be interested in the selector levers that form the group 52a of the selection system 52. On the other hand, all the others

  needles and all other punches must be rendered inactive.

  This is obtained by providing on the sub-needles 27 and 13 of all these needles and heel punches, for example at the level designated in 6 on

  Figure 3, and further providing for the selector lever therein

  the selection system 52, designated 52b, a control that keeps the lever depressed during the formation of the simple mesh area but with color drawing effects. This control can be advantageously provided from the live drum or

distribution of the trade.

  It is also necessary to put in the rest position the punches

2 46 581 3

  adjacent to the needles in the area where the stitches are formed

  simple with color drawing effects, to prevent their under-

  14 to climb on the cam 51. This condition is satisfied by

  it has two selector levers 52c included in the selection system 52, which can act on the heel at the level 8 or 10 of the sub-needles 13 of the punches 10 included in said zone and keeping these levers lowered throughout the formation of the zone in simple stitches

  C or diametrically opposite zone).

  It is obvious that even the selection made by the second

  selection system 52 is "negative", in the sense that the sub-needles

  the 27 needles 11 which do not have to seize the colored thread at

  feed point 50 must be depressed by one of the selec-

tors.

  For the rest, the formation of color drawing by thread goes

  established according to the method well known to specialists and which

  request no further explanation.

  As it appears in the light of the description below,

  In the two selection systems 25 and 52 provided in accordance with the present invention, there are two selector lever systems: a) The levers 25a which serve to select the needles provided for the formation of stitch-stitched meshes (in the system 25); - the levers 52a and 52c which serve to select the needles provided to form the color drawing and neutralize the respective punches (in the system 52);

  In these two selection systems, these levers are

  sent by a drawing drum of the programmable type.

  b) - The levers 25b, 25e and respectively 52b which cancel

  the two aforementioned types of selection.

  In the selection system 25, these levers are controlled

  by the device shown in FIGS. 4 and 5, and they select

  the needles and punches corresponding to the area

simple stitches.

  In the selection system 52, this type of levers is

  the machine's phase or timing drum to select needles and punches that do not belong to

the area in simple stitches.

  The sock according to the invention has qualities which can be summarized as follows: - Possibility of developing the knit mesh (openwork) on all the needles, since it is possible to form the single mesh area independently of the mesh pattern openwork, and then resume the formation of the stitched mesh by transfer of the point; - The fact of forming a single color drawing in the area of

  stitches, instead of two specular designs, brings the advantage

  to avoid long floating threads on the underside of the sock, which would then need to be cut in each row of stitches

  being able to put on the sock itself, but leaving

  knit a very short piece of yarn, which risks spinning stitches; on the contrary, by forming a single design, this drawback is eliminated, since the floating wires are very short and

can avoid cutting them.

  The sock according to the present invention, as described above and shown by way of example in FIG. 1, has a smooth-mesh zone C with color drawing effects which interrupts the openwork meshes, which , after this

  interruption, continue on the entire leg of the sock. This-

  during, it is understood that the present invention also covers

  a sock in which, after stitching

  openwork, the remaining part of the leg is made of simple stitches

  ples. In addition, it is also possible to make the entire part B of the leg in single stitches and to achieve the effect of color drawing in the only limited area C.

  Finally, it should be mentioned that the realization of a

  according to the invention should not be regarded as being strictly

  related to the type of circular sock loom described above. Indeed, the sock can be manufactured on any loom for socks, capable of forming openwork meshes, provided to install on this craft means to interrupt, in a pre-established area, the formation of these meshes openwork and to form in the same zone simple stitches with

color drawing.
