Description

The invention relates to a pulling comb for a straight knitting machine and a straight knitting machine as such incorporating such a pull comb. It also relates to a hooking plate of a pulling comb and a method of placing a wire, also known as a method of: assembling a wire, in a starting phase of knitting.

The conventional straight knitting machines comprise at least one front and rear needle bed, on which needles are arranged, and over which a cam carriage travels back and forth to actuate certain needles and thus to produce rows of needles. sts. The knit obtained is placed between the two needle beds and pulled down by a device based on rollers, called rollers, as and when it is knitted. A problem arises during the beginning phase of the knitting, since the latter does not yet have the 1: 5 length sufficient to present a portion disposed between the rollers for training. However, its downward pull is necessary in order to obtain efficient knitting with uniform stitches, and to prevent the knitting obtained from being placed in an incorrect position within the knitting machine, to be damaged or to cause a jam in the knitting machine. knitting machine.

The document FR2646176 proposes a solution in which a pull or mounting comb carries hooking or mounting needles that rise between the needle beds to grip the wire which has been arranged in a certain manner between the plates during a first time. passage of the cam carriage. Then, the comb descends progressively by causing the knit to reach its grip by the drive means. The mounting needles consist of two parts sliding relative to one another. The two parts comprise a hook or a protrusion 30 in their upper part, the protuberance of a first part .S531.12EN.37 DA deposition 2 delimiting a recess comprising the wire and the hook of the second part being able to slide towards the down to cause a release of this wire when necessary. This solution has the disadvantage of great complexity, each mounting needle having a complex structure. In addition, these mounting needles have their main hooks or protuberances oriented towards one of the needle beds of the machine, which requires a large separation of the two needle beds to allow the housing and movement of these mounting needles between the two needle beds. This large spacing of the two needle beds is a great limitation of the resulting knitting machine. In addition, this orientation to one of the two needle beds forms a non-symmetrical geometry, and the two needle beds can not be used indifferently to each other vis-à-vis these mounting needles, which represents another limitation of this solution.

Document US2007 / 0180864 proposes another solution in which the mounting needles comprise a lock making it possible to close or open a housing where the thread is positioned in the spout of the needle. When the mounting needles are in a low enough position, the spout is unlocked so that the thread it contains can be released automatically, thanks to the traction it receives and the orientation of the needle. However, this solution is not very effective because the wire is often stuck in the needle beak despite the opening of the lock, because this release of the wire is passive. In addition, all these needles have a beak oriented parallel to the beds in one direction, which represents an asymmetrical geometry. Overall, the knitted yarn is pulled with a component toward the center of the knit. With such a solution, on one of the two sides of the knit, the yarn is retained by the spout of the needle while on the other side, it tends to escape and must be retained by the lock. This asymmetrical construction is not ideal. It is a general object of the present invention to provide a straight knitting machine which has a solution for the beginning phase of knitting which is an improvement over the disadvantages of the foregoing solutions.

More specifically, a first object of the present invention to provide a pulling comb for knitting machine compatible with a very small spacing of the needle beds of the knitting machine. A second object of the present invention is to provide a pulling comb for knitting machine which allows a grip and then extraction of the imprisoned son with high reliability.

For this purpose, the invention is based on a pulling comb for a straight knitting machine comprising at least one hooking plate comprising at least one hook, extending mainly in a vertical longitudinal plane to have a small thickness in the direction transverse device, characterized in that it comprises at least one movable stripper relative to the at least one hooking plate so as to be able to extract a thread from the at least one hook. The pulling comb may comprise at least two gripping plates and a stripper between each gripping plate or comprise at least one gripping plate and a stretcher superimposed on each gripping plate.

The pull comb may comprise at least two hooks of substantially opposite orientation. The at least one attachment plate may comprise two hooks and the pulling comb may comprise a stripper capable of extracting a wire from two adjacent hooks of substantially opposite orientation.

The pulling comb may comprise at least two anchoring plates, each comprising two hooks of opposite orientation, oriented toward each other and may comprise a stripper disposed between each hooking plate.

In a variant, the at least one hooking plate may comprise two hooks of opposite orientation, oriented towards the outside of the hooking plate and may comprise a puller superimposed on the at least one hooking plate.

In addition, the at least one stripper can be movable in translation from bottom to top relative to the at least one mounting plate.

The pull comb may comprise a plurality of catch plates and the at least one stripper may include a groove on each side edge extending in the vertical direction to receive a catch plate in each groove and guide the relative movement translation between the at least one stripper and the latches. This pull comb may comprise a multitude of strippers in the form of vertical bars having an upper end moving closer to the hooks so as to directly extract a wire hooked around one or more hooks.

The pulling comb may comprise a multitude of plates and strippers, the plates being integrally mounted in their lower part on the same support, and the strippers being integrally .S531.12EN.37 DA 5 deposit mounted on the same base, the base and the support being movable relative to each other and extending longitudinally, adapted to be positioned substantially parallel to a bed of a knitting machine.

The invention also relates to a straight knitting machine characterized in that it comprises at least one needle bed and a pulling comb as described above.

The pull comb may be capable of vertical downward movement, a stop blocking the downward movement of the at least one puller and inducing its relative movement from bottom to top relative to the at least one hooking plate.

The straight knitting machine may comprise a knit driving device comprising two belts driven in opposite directions, passing over two small-diameter knuckles located near the at least one needle bed so that the knit requires a comb-type pull. draw on a short length.

The distance between the hooks of the pulling comb may be compatible with several different gauges of the knitting machine. The straight knitting machine may comprise at least two needle beds and the pull comb may be adapted to traverse a space of width greater than or equal to a few tenths of a millimeter for the implementation of the formation of a warm-up network .

Alternatively, the relative movement of the at least one stripper relative to the at least one mounting plate can be obtained using at least one motor. Finally, the invention relates to an attachment plate for pulling comb characterized in that it comprises at least two hooks of opposite orientation, extending mainly in a longitudinal plane. vertical to have a small thickness in the transverse direction. These objects, features and advantages of the present invention will be set forth in detail in the following description of a particular non-limiting embodiment in connection with the accompanying figures in which: Figure 1 schematically represents a view of face of a pull comb in a pulling phase by comb of a knit according to an embodiment of the invention; Figure 2 schematically shows a side sectional view of a knitting machine in a make-up network forming configuration according to the embodiment of the invention; FIG. 3 schematically shows a side sectional view of a knitting machine in an intermediate position close to the extraction configuration of the yarn of the pulling comb according to the embodiment of the invention; Figure 4 schematically shows a side sectional view of a knitting machine in an extraction configuration of the yarn of the pulling comb according to the embodiment of the invention; Figures 5a and 5b schematically show front and side views of latching plates of the device of the invention in a formation configuration of a start-up network corresponding to Figure 2; 5 .S531.12EN FIG. 6a and 6b schematically show front and side views of latching plates of the device of the invention in a start-of-extraction configuration of the wire; FIGS. 7a and 7b schematically represent front and side views of latching plates of the device of the invention in a wire extraction configuration corresponding to FIG. 4; Figure 8 schematically shows a front view of latching plates according to a variant of the embodiment of the invention; Figure 9 schematically shows a front view of latching plates according to another embodiment of the embodiment of the invention; Figure 10 schematically shows a front view of latching plates according to another embodiment of the embodiment of the invention.

For reasons of clarification of the following description, we will call longitudinal direction x the direction parallel to the plane of the needle beds of the knitting machine, the vertical direction z that from the bottom upwards, perpendicular to the longitudinal direction, and the transverse direction y the direction perpendicular to the two previous ones. Similarly, we will use the same references and directions to describe the pull comb and its elements, regardless of the knitting machine, with reference to the position they are intended to occupy within a knitting machine in a phase. traction by comb. 2.5 The pulling comb 11 according to an embodiment of the invention, partially shown in front view in FIG. 1, consists of an alternation of gripping plates 13 and strippers 23, each gripping plate 13 lying on a large part of its 31) width, measured in the longitudinal direction x, integrated in a .S531.12FR. 37 DA deposition 8 groove 25 of each of its two adjacent strippers 23, so as to allow a relative translational motion by sliding the strippers 23 relative to the needles 13 at their connection by groove. All these elements 13, 23 are securely fixed at their base, by the support of plates 12 for the latching plates 13, and by the base 22 for the strippers 23, as can be seen in FIGS. 2 to 4, so that all the latches 13, respectively all the strippers 23, remain at an identical height and form an inseparable assembly, movable uniformly. This construction provides a relative mobility in translation of all the latching plates 13 and all the strippers 23, this relative movement being guided by the cooperation of the two sets of elements by their connection in the grooves, which the game is reduced to guarantee a well-controlled translation movement. Alternatively, any other mechanical connection 1: 5 to obtain this translational movement between these two sets can be considered.

According to this embodiment, each attachment plate 13 is in the form of an elongated flat bar, of less than 1 millimeter thickness in the transverse direction y, with a width close to one centimeter in the longitudinal direction. x and height slightly greater than ten centimeters in the vertical direction z. Each attachment plate 13, also called comb plate, comprises a head 14 in its upper part adapted to cooperate with a wire 9. For this, 2.5 the head 14 comprises two lateral arms 15 extending vertically and ending in a upper tip 17. In addition, the two arms 15 each form a hook 16 in their upper part, oriented towards the inside of the plate so that the two hooks 16 are oriented towards each other in a substantially opposite direction in the x direction of the platen width. The two hooks 16 have a geometry .S531.12FR.37 DA deposition 9 defined in a vertical longitudinal plane xz. A wire 9, positioned in these latching plates 13 during the formation of the start-up network forms a loop around two adjacent hooks 16 belonging to two different and neighboring fastening plates 13. A wire 9 can thus: be hooked into the hooks 16 of the latching plates 13. When the pulling comb 11 moves downwards, a knit 10 is thus driven downwards.

The strippers 23 are movably mounted in translation in the direction parallel to the catch plates 13, in a substantially vertical direction. Each stripper 23 is also in the form of a flat metal bar, however, having a thickness greater than that of the attachment plates, to include two grooves 25 extending over their entire height in a vertical longitudinal plane xz. The depth, measured in the longitudinal direction x, of the lateral grooves of the stripper 23, made at their side edge, corresponds substantially to half the width of a catch plate 13. Each groove of the stripper 23 incorporates a 13. Each spoiler 23 is thus symmetrically distributed in the transverse direction y on each side of the latching plates 13, which offers a symmetrical solution vis-à-vis the two needle beds 2 of the knitting machine. and the loop obtained with the wire 9 can thus originate indifferently from one of the two needle beds 2. Each stripper 23 has a head 24 in its upper part which ends in a point 27. The head 24 also has a surface 28 inclined, so to be less and less thick going towards the point 27 of the stripper. Thus, this point 27 of the stripper 23 is thin, of reduced width, and positioned closer to the surface of the latches 13 by its connection with little play with the plates, guaranteed by the grooves. Each stripper 23 fills a withdrawal function of the wire 9 included in the hooks 16 of the latching plates 13 by a movement from bottom to top, as will be detailed later, and can also be called wire extraction means or extractor. In the draw pull design of a knit 10, shown in FIG. 1, the tips 17 of the catch plates 13 are at a height greater than that of the tips 27 of the strippers 23, so that the head 14 of the latches 13 exceeds a few centimeters from the tip 24 of the strippers 23 to be able to receive the knit starting network and then cause the knit 10 without discomfort and without the bulk of the strippers 23.

Figures 2 to 4 show a schematic diagram of an embodiment of the invention in which a straight knitting machine incorporates a pull comb 11 as described above. The knitting machine comprises two needle beds 2 carrying needles 3. A space 4 between these needle beds allows a knit 10 to escape down during knitting. The machine is furthermore equipped with a drive device 20 for knitting 10 based on rollers, for example as described in patent FR 2 368 672. The driving device 5 makes it possible to drive the knit 10 downwards when it has a sufficient length, as is the case in the configuration illustrated in FIG. 4.

2.5 This driving device 5 essentially comprises two endless belts, of rubber or of similar material, driven by two tubular drums in their lower part and passing on two referrals in their upper part, for example constituted by simple cylindrical bars of metal of small diameter. This configuration makes it possible to arrange the drive device 5 as close as possible to the needle beds 2 and to reduce at best the length of knitting required before being driven by the rollers. The knit 10 is engaged between the belts immediately below the mesh formation zone by the plates. Between each of the drums and bends is a frame, consisting of a prismatic block extending over the entire length of the drums and having a cylindrical surface groove through which it is supported by sliding on the drum, and a second groove serving from level to references. The blocks have laterally two planar faces serving as a guide to the rectilinear paths of the belts. The drums of the belts 10) are driven in opposite rotation, which not only has the effect of driving the belts, but also of driving the frames in this rotation, so that they tend to come to rest against the against each other, with their strap, by pinching the knit which is then drag-dragged downward. Alternatively, any other drive device 1.5 could be used.

The operation of the pull comb 11 will now be detailed. The beginning phase of the knitting can be divided into three phases.

First, Figure 2 illustrates the formation of a make-ready network, which consists of the distribution of a wire 9 in the hooks 16 of the pull comb. In this step, the pulling comb 11 is positioned in its highest position, so that the hooks 16 of its catch plates 13 pass through the space 4 between the two needle beds 2, up to a height greater than that of these two needle beds 2. In this position, it is well adapted to the recovery of a wire 9 between its hooks 16, to obtain a configuration as illustrated in Figures 5a and 5b. In this configuration, the strippers 23 remain in a low position under the space 4 of the needle beds, which makes it possible to reduce the size of the part of the pulling comb positioned in the space 4. between the beds.

After completion of this start-up network, the pull comb is capable of driving a knit 10 downwards. Towards the end of the knit pulling period of the knit 10, as illustrated in FIG. 3, the pulling comb 11 descends downwardly from the rollers, causing the knit 10, which continues to be knitted from conventionally by the needles 3 disposed on the needle beds 2. After the release of the rollers of the latches 13, the stroke of the draw draw comb 11 is deflected slightly laterally. In this configuration, the knit 10 is already mainly driven by the rollers.

FIG. 4 illustrates the phase of release of the knit 10. In this phase, the base 1: 5 of the strippers 23 rests on a stop 6 while the support 12 of the catch plates 13 continues its descent. This configuration induces a relative translational movement between the strippers 23 and the plates 13. The latter 13 descend while the strippers 23 remain at a constant height imposed by the stop 20 6. Thus, the tip 27 of the strippers is slipped into the loop formed by the wire 9 present in the hooks 16 of the latches 13 to extract this loop 9 out of the hooks 16, resulting in the final extraction of the knit 10 of the grip of the pulling comb 11. A stop 7, at which the upper part of the pulling comb is positioned in this phase, prevents the end of the freed knit from moving in the wrong direction where it could lock, for example laterally, and forces it to refocus under the machine. Then, the knit 10 is simply driven by the rollers 5 and down to the center of the machine, and the starting phase 30 of the knitting is completed. The pulling comb 11 which has been moved laterally at the end of the stroke is then retracted and does not hinder the stroke of the knit 10.

Figures 5 to 7 illustrate more precisely the geometry of a portion of the end of the pulling comb 11 and its different configurations in the comb pulling phase of the knit.

FIGS. 5a and 5b illustrate in particular two adjacent latching plates 13 in the high position and a stripper 23 in the low position. A wire 9 is positioned in these plates 13 and forms a loop around two adjacent hooks 16 belonging to two different neighboring plates. Each groove of the stripper 23 incorporates a hooking plate 13. The stripper 23 is thus symmetrically distributed in the transverse direction y of each side of the attachment plate 13. The assembly 1: 5 of the upper part of the comb of draw 11 thus has a symmetry with respect to a longitudinal median plane xz and the loop obtained with the wire 9 can thus originate indifferently from one of the two needle beds 2.

FIGS. 6ab and 7ab illustrate two states of the wire extraction phase 9 of the grip of the pull comb 11. As illustrated in FIGS. 6a and 6b, after a bottom up movement of the stripper 23, its point 27, V-shaped upwardly, whose tip is truncated to not damage the wire 9, is positioned at the wire 9 which forms a loop around the hooks 16 of the attachment plate 13. This tip 2: 5 27 is thin, of reduced width, and positioned closer to the surface of the plates 13 since the connection between the plates 13 and the strippers 23 has little play. Thus, it inevitably moves under the loop of wire 9 presents around the hooks 16 when it continues its upward stroke relative to the plates 30 hooking 13. Indeed, continuing their descent, the hooks 16 .S531.12EN.37 DA deposition 14 of the plates 13 end up occupy a position of lower height at the point 27 of the stripper, inside the grooves 25 of the stripper. As the width of the stripper 23 is greater than the distance separating a hook 16 from the adjacent hook 16 of the adjacent plate, the loop of wire 9, wound around these two hooks 16, which is driven by the spike 27 of the stripper 23, widens sufficiently to escape the hooks 16 of the plates 13, as shown in Figures 7a and 7b. The yarn 9 and all the knit 10 is thus extracted from the pulling comb 11. This operation is carried out simultaneously on all the plates 13 of the pulling comb 11, by the same relative movement from bottom to top of the strippers 23.

In the embodiment described above, the solution thus has the following advantages: 1: 5 -the gripping plates 13 pass through the space 4 between the needle beds 2 in the direction of their thickness, ie their smallest dimension, and are adapted to a very small space 4, which allows to consider a very close positioning of the needle beds 2, up to a few tenths of a millimeter only. This advantage is achieved in particular by the fact that the hooks 16 of the plates are oriented in a vertical longitudinal plane xz and have a small thickness in the transverse direction y; -As the strippers occupy a low position at the time of formation of the start-up network to subsequently perform 2.5 upward movement relative to the plates, they do not encumber the upper part of the pull comb which is arranged between the needle beds; the latching plates 13 have two hooks 16 symmetrical with respect to a vertical median plane yz transverse to the 3 latching plates 13. This makes it possible to hang a loop of wire 9 .S531.12EN.37 DA depot 15 around two hooks of different orientation, which form a set in the shape of a harpoon. This solution allows a wire 9 to be maintained effectively and identically on each lateral side of the knitting machine; the use of a stripper 23 to grip the wire 9 and extract it from the hooks 16 of the hooking plate 13 ensures a reliable extraction of the knit 10 and avoids the jamming of the machine by improper release of the knit and / or damage to the knit fabric due to unwanted and undesirable pulls undergone in poor release situations; the combination of the pulling comb 11 of the invention with the drive device 5 described above, positioned as close as possible to the needle beds, makes it possible to reduce this drawing pulling phase as much as possible and the distance to be traveled by the pull comb before pulling the wire. This therefore reduces the length of knitting that is performed with this principle of specific traction at startup. This length may be equal to about 60 millimeters, is in any case less than 70 millimeters. This represents a great advantage because the transfer of the draw pulling traction 11 of the knit 10 to its traction by the drive device 5 in the subsequent knitting regime induces visible differences in the knitted stitches. It is therefore important to reduce the size of the knit obtained in the beginning phase of pulling by comb in order to avoid obtaining a non-aesthetically shared knit in two important areas of different stitches; the relative movement between the strippers and the plates is simply mechanical, does not require an engine, which represents a simple and economical solution. However, it is possible to imagine any other relationship between the two parts and the relative movement using one or more engines. Of course, the invention is not limited to the geometries of gripping plates 13 and strippers 23 described above.

In addition, the combination of symmetric orientation hooks with respect to a vertical transverse plane yz has the advantage of effectively maintaining the wire. This advantage could be obtained by other embodiments, for example by choosing plates having a single hook, each receiving a wire, whose orientation is inverted on each side of the machine so that the hooks are all oriented. towards the outside of the machine on both sides of the machine. Another solution, still using hooking plates with a single hook, would be to alternate the orientation of the adjacent hooks of the neighboring hooking plates to be able to have a looped wire on these two adjacent hooks forming a harpoon, a The extinguisher is then housed between these two 1.5 adjacent latches. As a variant illustrated in FIGS. 8 to 10, each plate 13 could have two hooks 16 oriented towards the outside of the plate, respectively via two distinct arms 15 or a single arm. In such a variant, the wire 9 forms a loop around these two hooks of the same plate. Thus, the strippers 23 are no longer necessarily positioned between two adjacent fastening plates 13 but a stripper 23 can be positioned centrally and superimposed on each attachment plate 13, as shown in Figures 9 and 10. The movement relative of the two elements can be obtained via a vertical central groove 19 extending over substantially the entire height of each latching plate 13, in which are housed unrepresented through elements of the strippers, so that have little play and ensure a translational movement maintaining the tip 27 of the strippers to the closest to the surface of the latches. According to another variant, each hooking plate may comprise two hooks of the same orientation. Other variants may be obtained by the combination of the solutions presented above, for example using hooking plates with four hooks, each carrying at least one superimposed stripper and / or a stripper disposed between the plates.

Any mounting plate 13 having a spout, hook or any other form allowing the attachment of a wire could be suitable, from the moment when the hooking means wire is mainly oriented in a vertical longitudinal plane xz, in order to keep a smaller thickness in the transverse direction y. However, nothing prevents to imagine a hook with a three-dimensional shape, also having an extension in the transverse direction y, for example conical or cone portion, to further improve the attachment of a wire. This solution may be an alternative embodiment of the invention in knitting machine configurations having two needle beds separated by a sufficient spacing. But according to the invention, the hooks 16 of the attachment plates have their maximum size in the longitudinal direction x and / or the vertical direction z, in the vertical longitudinal plane xz.

The illustrated solution comprises a multitude of fastening plates with two hooks; however, these hooks could be mounted on a single body or a single plate. Finally, any solution comprising at least one plate and at least one hook is possible without departing from the concept of the present invention.

In addition, the stripper can have any other form allowing its movement relative to the latching plates to arrive at a 3D extraction of the wire of the plates. For example, its upper end 27 deposit may have a rounded shape, as shown in FIG. 10, or a V shape having two tips, as shown in FIG. 8. More generally, this end will have any non-cutting shape to avoid damaging the wire. Preferably, this extraction S of the wire loop 9 of the hook of the plate is obtained by a direct action, a direct contact of the stripper on the wire. Finally, the wire has been advantageously represented as forming a loop around two hooks to allow easy grasping by the stripper. However, any other arrangement of the wire may be considered. This solution is advantageous on a straight double-needle knitting machine. Nothing, however, prevents its implementation on a knitting machine with a single needle or more than two needle beds, for example four or six. The elements of the pull comb will preferably be metal but may also be optionally rigid plastic.

The invention also makes it possible to implement two methods of forming a start-up network on the latching plates 13.

According to a first method, the initialization thread of the knitting, generally having a particular elastic property, is first placed between the needles 3 of the knitting machine, according to a distribution allowing it 2: 5 to form a predefined network of knitting machines. a needle to the other, with parts thus crossing the space 4 between the needle beds. When this network of wire 9 is established, the pulling comb 11 which was in a low position is then mounted to arrange its plates 13 between the needle beds 2 at the wire 9 predisposed. Then, the pulling comb is lowered and in this downward movement, its plates 13 then drive the wire whose grating 1: 5 .S531.12EN.37 DA has been provided to match the geometry of the hooks 16 13. For this, it is expected that the thread passes from one needle to the other at the hook which must grasp it. In addition, according to an advantageous embodiment, the geometry, in particular the width of the hooks of the plate and of the assembly of the pulling comb, can be provided to correspond to a multiple of several different gauges of knitting machines, the gauge representing the distance between needles 3 mounted on the beds. Thus, the same pulling comb 11 is adapted to several different gauges of knitting machine. 1 ') According to a second method of formation of the start-up network, the pulling comb 11 can first be positioned in a high position in which the hooks 16 of its latching plates protrude above the level of the needle beds 2. Then only, the thread 9 is brought and 1.5 directly knitted with on the one hand some needles 3 of the needle beds 2 and on the other hand with the latches 13, to obtain its grip by the pull comb 11 .
