Description

The invention relates to a method for the production of rib knit sections on tubular round finished knits on a flat knitting machine with at least two opposing needle beds, wherein for producing the right mesh on the visible side of the rib knit sections of the first knit level on the first needle bed are formed with all the needles of a group of needles for forming the stitch loops meshes and for the production of the left stitches on the visible side of the rib knit sections on the second needle bed with every other free needle stitches between the stitches for the second knitting layer supporting needles and the production of the Right and left stitching for the second knit fabric level is carried out in an analogous manner with needles of the second and first needle bed.

Such a method is from the EP 148 161 A2 the applicant for the production of tubular Rund-Fertiggestricken known. With this known method it is possible, without the use of a third and a fourth needle bed, to produce tubular round knitted fabrics in which each needle must form stitches in the plain knit area and patterns must be left and right stitches on each knitted fabric side.

While the known method has set itself the goal of producing individual, vertically limited rib sections in regular 1: 1 or 2: 2 patterns in a knit piece, the known method is not yet suitable in Form knitted garments produce that have arbitrarily wide ribs, which can extend from the fabric start to the knitting end, running vertically.

The present invention is based on the object, the known method such that it can be made with him round tubular knit fabrics with rib knit sections that are knitted in the field of rib knit sections in shape, so areas especially with a mesh reduction. A method of this kind is described in the EP-A-1 055 754 A2 of the applicant described.

According to the invention the object is achieved with a method of the type mentioned in the present invention that to reduce the tubular Rund-Fertiggestricks in the rib knit section the stitches of a link mesh group on the left and right side of the first and second knit level on adjacent needles directly then hung on the inside adjacent right-hand knit group, then hung to the stitches of the inside adjacent right-hand knit group, while the outside adjacent right-hand knit group is also hung around a corresponding number of needles inside, then courses for the first and second knitted fabric formed and then the loops of the outer right-hand knit group are transferred to the needles of the inner right-hand knit group so that the round-knit tubular knit fabric on the left and right sides of each knit level is separated by one rib, i. H. has been reduced by one link mesh group and one legal mesh group.

With the method according to the invention thus tubular round finished knitted fabrics can be produced with longitudinal ribs, in which a reduction must be carried out. Also, a mesh increase is of course possible in the method according to the invention, for which purpose standard methods can be used. Thus, using the method according to the invention, knitted pieces, for example pullovers with a ribbed structure, which have the appearance of flat knitting machines, are produced have knit pieces made with four needle beds and feel just like these. However, two-ply flat knitting machines are less expensive than four-ply machines and therefore more widely used.

The inventive method results in a uniform mesh appearance, since the reduction always takes place to a complete rib width.

The transfer of the left and right stitches to the needles of the inside adjacent stitch group can be done by means of transfer devices. It can be used as transfer devices separately from the needles mounted and drivable transfer elements. However, it is also possible to use as transfer devices slider of the needle needles, wherein the slide have two leaf-shaped spring elements which laterally comprise the hook of the needle needles. The use of separate transfer elements has the advantage that the capping operations can be performed overall faster than when using machines with special needles, in which a transfer of stitches is possible only on one needle of the opposite needle bed.

The transferring of the link meshes to be reduced to adjacent needles to the inside adjacent legal mesh group can also be done by means of the transfer devices. Another possibility is to perform these capping operations using needles of the opposing needle bed.

Hereinafter, an inventive knit fabric and preferred method for its production will be explained with reference to the drawing.

In Fig. 1 a sweater 1 is shown with rib-knit pattern, which is formed as a tubular Rund-Fertiggestrick on a flat knitting machine with two opposing needle beds and capping devices and transfer devices. In the example shown, the rib pattern runs on the torso 2, on the right sleeve 3 and on the left sleeve 4 in each case from the starting knitting row to the last knitting row. According to the method of the invention, the right-hand stitch groups 21, 31, 41 are formed on the needle bed of the visible side with each of the successive needles. The link mesh groups 22, 32, 42 are formed on the needle bed opposite the view side needle bed with only every other needle. For example, to create a rib knit with the appearance of a 3: 3 ripple pattern, the right stitches with groups of needles are formed by three needles in which each needle knits, and the stitch loops with groups of needles of six needles, in which only every second Needle knits. The rib structure can be arbitrarily selected, and the number of stitches and the number of stitches may be the same or different. The number of stitches is identical to the number of needles required for this. The number of links meshes requires twice the number of needles.

In the illustrated example, the pullover 1 in the section A widens the hosiery knit with an increase technique according to the prior art. In a section B, the hull knit is reduced with a mitigation technique according to the invention. The connecting lines 6 and 6 'of the right and left sleeves 3, 4 with the fuselage 2 are inclined in the example shown. The neckline 5 is formed as a round neck.

The Figures 2.1 to 2.3 show the course of stitches for the production of the ribbed knitwear pullover Fig. 1 with 3: 3 ribs in an area without mesh increase or reduction.

In row R1, the stitches of the link mesh groups of the back fabric side are transferred to their opposite needles. Subsequently, in rows R2, the groups of left and right stitches of the back fabric side are formed on the front and back needle beds. Thereafter, in rows R3, the link mesh groups of the back fabric side are hung back onto the needles of their mesh bandage. Row R03 now shows the stitching of the back fabric side after making a course. The right-hand knit groups comprise three needles: from left to right, these are needles 1-2-3, 10-11-12, 19-20-21, 28-29-30, 37-38-39. The link mesh groups comprise six needles, of which only every other stitch forms. From left to right these are the needles 5-7-9, 14-16-18, 23-25-27, 32-34-36. In the rows R4 to R6, the preparation and forming of a stitch row for the front fabric side is now shown. In row R4, the stitches of the lefthand knit fabric groups of the front fabric side are transferred to their opposite needles, and then in rows R5, the groups of left and right laces of the front fabric side are formed on the front and back needle bed. Subsequently, in rows R6, the left-hand knit groups of the front fabric side are hung back onto the needles of their knitted fabric. Row R06 shows the mesh of the front fabric side after forming a course. The needle groups of the right and left meshes are identical to the back Knitted side (R03). In contrast to the R03 series, the links are formed with the needles 4-6-8, 13-15-17, 22-24-26, 31-33-35.

The knitting process R1 to R3 and R4 to R6 is repeated until the number of knitting rows required for each knitted fabric is formed.

The chosen representation of the knitting sequence corresponds to a knitting machine with which a row of knitting can be formed during a carriage movement. It is self-evident that in multi-system machines, the individual knitting rows shown can be summarized.

The Figures 3.1 to 3.8 now show the reduction process on the left and right front and back of the pullover 1 Fig. 1 in section B according to a first method of the invention.

The looping operations from needle to needle (R1 to R7) take place in the looping operations required for the actual reduction process of the left stitches. In the actual reduction process, the stitch transfer from the needle to a transfer element to a needle (R8 to R11, R18 to R21) occurs.

In row R1, the left stitches of the mitigating rib portion of the left front side and the right back side of the fabric are transferred to their opposite needles. Subsequently, in row R2, the rear needle bed is offset by one needle to the right. The innermost links meshes are transferred to their opposite needles (8 to 9, 32 to 31). Thereafter, in row R3, the rear needle bed is shifted to the right by another needle. The meshes that have now become the innermost links mesh are transferred to their opposite needles (6 to 8, 34 to 32). In row R4, the back needle bed is again offset by one needle to the right. The last links meshes are transferred to their opposite needles (4 to 7, 36 to 33). In series R5 the rear needle bed has been moved to its basic position. The extreme left stitches of the mitigating rib portion of the left back and right front of the knit are transferred to their opposite needles. Thereafter, the back needle bed is shifted one needle to the left, and the left-back and right-front stitches turned to the leftmost stitches are transferred to their opposite needles (7 to 6, 33 to 34) before the back needle bed in row R7 by two more needles to the left and the two left-hand stitches of the left back and the right front of the knit are transferred to their opposite needles (5 to 7, 6 to 8, 34 to 32, 35 to 33).

Row R07 shows the situation in which the loop stitches of the link meshes required for the actual reduction of the rib area are completed. The left stitches on the left and right back sides of the fabric are located on the needles 7-8-9 and 31-32-33 of the back needle bed and thus directly next to a stitch group. The left stitches of the left and right knit front sides participating in the rib reduction are located on the needles 7-8-9 and 31-32-33 of the front needle bed and thus directly next to a stitch group.

In row R8, the rear needle bed is moved to its basic position. The left and right stiches of the rib area of the right front and the left back of the knit involved in the abatement process are transferred from the needles to corresponding transfer elements (31-32-33, 37-38-39, 1-2-3, 7- 8-9). Then, in row R9, the back needle bed and the back transfer elements are offset by three needles to the left. The stitches of the right front and the left back of the knit on the transfer elements are transferred to their needles in the front and back needle bed (28-29-30, 34-35-36, 4-5-6, 10-11-12 ). As a result, the links meshes involved in the reduction process are attached to the needles of their knit center adjacent right stitches Service. In row R10, the left and right stitches of the ribbing portion of the left front and right back of the knit involved in the mitigation process are transferred from the needles to their associated transfer members (1-2-3, 7-8-9, 31-32- 33, 37-38-39). Subsequently, the rear needle bed and the rear transfer elements are brought into their basic position. The stitches of the left front and right back sides of the knitted fabric on the transfer elements are transferred to their needles in the front and back needle bed (4-5-6, 10-11-12, 28-29-30, 34-35-36 ). As a result, the links meshes involved in the abatement process have been hung on the needles of their inner adjacent stitches (row R11). In row R12, the stitches of the back-knit fabric stitching groups are transferred to their opposite needles before the back-knitting fabric row R13 forms the first course after the rib stitching-down process on the front and back needle beds. In row R14, the link mesh groups of the back fabric side are hung back onto the needles of their mesh and in row R15 the stitches of the left mesh groups of the front fabric side are transferred to their opposite needles. In row R16, for the front knit side, the first row of stitches is formed on the front and back needle bed after the reduction operation of the rib stitches on the front and back needle beds, before the rows of stitches on the front fabric side are hung back on the needles of their stitching in row R17. Subsequently, the right-hand stitches of the ribbing portion of the right front side and the left back side of the knit fabric involved in the reduction process are transferred from the needles to their associated transfer elements (row R18). In row R19, the rear needle bed and the rear transfer elements are shifted six pins to the left. The stitches on the right front and left back sides of the fabric are transferred to their needles in the front and back needle beds (28-29-30, 10-11-12). As a result, the legal meshes involved in the reduction process are attached to the needles of their knit center adjacent right stitches Service. In row R20, the right-hand stitches of the reducing portion of the left front and right back sides of the knit fabric are transferred from the needles to their respective transfer members (4-5-6, 34-35-36). Subsequently, in row R21, the rear needle bed and the rear transfer elements are brought into their basic position. The stitches of the left front and right back sides of the fabric are transferred to their needles in the front and back needle bed (10-11-12, 28-29-30). As a result, the legal meshes involved in the reduction process have been attached to the needles of their inner adjacent adjacent stitches. The complete knit has been reduced on the left and right front as well as on the left and right back by one rib area (three left and three right stitches).

The Figures 4.1 to 4.4 show a further variant of a method according to the invention for reducing tubular Rund-Fertiggestricken with rib structure. In the case of the capping operations of the left meshes required as preparation for the actual rib reduction process, in this process variant the stitch transfer from needle to transfer element to needle takes place. The actual rib reduction process is identical to that in the Figures 3.1 to 3.8 (R8 to R11 and R18 to R21) described.

In row R1, the knitting edge center and outermost stitch loops of the mitigating rib portion of the right front and left back of the knit are transferred from the needles to their associated transfer members (FIGS. 33 to 35, FIGS. 5 to 7). Subsequently, in row R2, the offset of the rear transfer elements about a needle to the left and the front transfer elements around a needle to the right. The left stitches of the right front and the left back of the knitted fabric on the transfer elements are transferred to their needles in the front and rear needle bed (32 to 34, 6 to 8). In row R3 the front and rear transfer elements are brought into their basic position. The outermost links mesh of the rib area involved in the mitigation the right front and the left back of the knit are transferred from the needles to their associated transfer elements (34, 6). In row R4, the rear transfer elements are offset by one needle to the left and the front transfer elements by one needle to the right. The left stitches of the right front and the left back of the knitted fabric on the transfer elements are transferred to their needles in the front and rear needle bed (33, 7). Thereafter, in row R5, the front and rear transfer elements are returned to their home position. All of the left stitches of the mitigating rib area of the left front side and the right back side of the fabric are transferred from the needles to their associated transfer elements (4-6-8, 32-34-36). In row R6, the rear transfer elements are offset by one needle to the right and the front transfer elements by one needle to the left. The left-hand stitches on the left front and the right-hand back sides of the fabric are transferred to their needles in the front and back needle beds (5-7-9, 31-33-35). Subsequently, the front and rear transfer elements are returned to their basic position (row R7). The knit edges of the middle and outermost left stitches of the mitigating rib portion of the left front side and the right back side of the knit fabric are transferred from the needles to their respective transfer elements (FIGS. 5 to 7, 33 to 35). In row R8, the rear transfer elements are offset by one needle to the right and the front transfer elements by one needle to the left. The left-hand stitches of the left front side and the right back side of the fabric on the transfer elements are then transferred to their needles in the front and rear needle bed (6 to 8, 32 to 34). Subsequently, the front and rear transfer elements are returned to their basic position in row R9. The outermost links meshes of the rib area of the left front side and the right back side of the knit fabric participating in the reduction are transferred from the needles to their associated transfer elements (6, 34). In row R10 are located on the transfer elements links meshes of the left front and the right back of the knitted fabric on their needles in the front and rear needle bed (7, 33).

Row R010 shows the situation after completion of the preparatory mesh capping operations required for the actual reduction of the rib area. The left stitches on the left and right back sides of the fabric are located on the needles 7-8-9 and 31-32-33 of the back needle bed and thus directly next to a stitch group. The left stitches of the left and right knit front sides participating in the rib reduction are located on the needles 7-8-9 and 31-32-33 of the front needle bed and thus also directly next to a stitch group.

Then, now in the Fig. 3.1 to 3.8 described reduction process (R8 to R11 and R18 to R21) are performed.
