"Mesh take-up mechanism for having an automatic edge transfer device equipped V flat knitting machines "

The present invention relates to a stitch take-up comb for flat knitting machines, which preferably with an automatic device for picking up the edge stitches and a magazine comb for transferring them are equipped. A machine of the aforementioned type is for example in the Belgian patents 67S 851 and 781 778 of the Applicant described.

In practice, the caliber of the Mass equipped with a loop engaging mechanism knitting machines do not generally lasts for more than Ik pins / in "The Cotton knitting machines but often have a caliber Mass of 16 needles / inch. In these cases, the edges ¹ must be knitted according to the size IU and then transferred to combs of the size IS zn. This requires the use of specialized _personnel's the "but nowadays increasingly rare ⁵ and more expensive - is *

The ¹ present invention is now set the task of creating a mechanism _{9 of} the ⁵ see is suitable around the edge

to pick up meshes on a machine of a certain caliber and then easily transferring them to a magazine comb of a different caliber size.

For this purpose, according to the invention, an essentially The mesh pick-up comb consisting of the following parts is used: several pencil support blocks arranged in a row, each of which carries one or more pivot pins; Means to decrease or increase the distance between these blocks; and Means to pivot the aforementioned pins in one or the other of two predetermined angular positions and to close in this position To block.

The characteristics and advantages of the system according to the invention are evident from the detailed description below a machine according to the invention, which takes place on the basis of the accompanying drawings, where

Figure 1 shows a front view of a machine according to the invention schematically;

Figures 2 and 3 show two top views of the stitch pickup comb according to the invention in two characteristic positions schematically reproduces; and

Figures H and 5 show the stitch pickup comb according to the invention shows schematically with its accessories in two characteristic positions.

The machine according to the invention shown in the accompanying drawings has two fonts 1 and 2, as well as with an automatic device for picking up the edge stitches and transferring them to a magazine comb 3 fitted. This device essentially consists of • - 409885/0344

a mesh take-up cairan H with its guide and control mechanism and a mesh transfer comb 5.

At the end of the knitting of an edge, all stitches are transferred to the rear font 1 and then through the Aufnähmekamm U added, which they by shifting the edge presented to the aforementioned magazine comb 3. The stitches are finally carried out by the transmission comb 5 from the pins of the Transfer the comb U onto the pins of the comb 3.

It is a device of known construction and mode of operation.

The receiving comb 4 consists of the one according to the invention System of several pencil support blocks 6, which are resiliently are connected to one another by U-shaped stops 7; These stops are mutually offset and are located with one another in engagement. Each stop 7 is on the one hand attached to the corresponding block 6 with a screw 8, for example, and acts on the other hand together with the fixed end of the adjacent stop, and vice versa. The outer blocks are provided with half stops 7 '.

Suitable means, here schematically in the form of Compressed air cylinders 9 reproduced are used for opening and closing the comb. On picture 2 the comb is in his reproduced closed position. The blocks 6 touch each other. The distance d, between the cooperating parts two adjacent stops 7 corresponds to a step of the coarser of the two relevant caliber dimensions. So if the comb is open (Figure 3); the distance between two adjacent blocks is also d,.

409885/0344

Each block 6 carries several pins 10, which are pivotably arranged on the block with their lower end 11, the distance d ₂ between two successive pivot axes corresponding to a step of the finer of the two relevant caliber masses.

With the comb 4 described above, two are involved

Combs 12 and 13 provided with intermediate parts, which are attached to the end of the levers It and 15. One (14) of these levers are pivotally mounted on a shaft 16 carried by support 17, while the other (15) about the axis 18 below the Comb 4 can swivel.

The aforementioned supports 17 clamped on a shaft 19 also carry the comb 4. The angular position of the aforementioned Lever 14 is according to the programming of the machine with a suitable device, for example with several compressed air cylinders 20, controlled. Similarly, the angular position of the lever 15 with the compressed air cylinders 21 or other suitable Means, controlled, which act by means of the rods 23 on the control levers 22 articulated on the shaft 19. The teeth or intermediate parts of the comb 12 correspond to the coarser of the two caliber dimensions.

The effect of the above-described mechanism according to the invention can essentially be described as follows. After the last row of an edge has been knitted, the stitches hanging on the needles of Fontur 1 are closed through the Comb 4 located in the position was added, the intermediate parts of the comb 12 engaging between the pins 10. the The row of stitches is now removed. Blocks 6 are now moving closer

409885/0344

together under the influence of the cylinder 9, while the intermediate parts the comb 13 replace this in its rest position (Fig.4) moved comb 12, while the blocks 6 move together under the Influence of the cylinder 9. As a result of the moving together of the blocks 6 and the activation of the comb 13, the comb 4 now has the finer caliber mass corresponding to that of the magazine comb 3, so that the transfer can now take place on the latter.

Then the comb 4 opens, while the comb 12 opens the place of the ridge 13 occurs. As a result, the receiving comb 4 is ready to start a new cycle.

Of course, that according to the invention is limited System in no way based on the embodiment described above, explained by the accompanying drawings, but it comes for the most diverse modifications, additions and adaptations of the same within the scope of the invention in question. That's how they are Number of blocks 6 and the number of pins on each block vary widely between widely spaced boundaries. In addition to the transition from the caliber dimension 14 to the dimension 16 in the exemplary embodiment described above, there are also many other transition ratios in question, such as 10/12, 12/14 and 16/18. This means a great reduction in the number of different, at the size of the caliber to be provided for programming the machine.

The comb 4 can have a recess in its center for the simultaneous knitting of two cuffs, for example according to that described in the applicant's Belgian patent 781 778 Have procedures.

Furthermore, the aforementioned combs 12 and 13 can consist of one or preferably of several parts.

409885/0344

In addition, the area of application of the mesh is limited In no way does it take part in the present invention on the automatic takeover and transfer of edge stitch courses. It is readily apparent that the comb according to the invention is also suitable for semi-automatic and completely automatic transmission processes for machines other than edge knitting machines.

The above-described exemplary embodiment of the system according to the invention relates to the transition from a coarser one to a finer caliber, although this system can of course be used equally well suited for the opposite case, i.e. for the transition from a finer to a coarser caliber. In addition, two combs according to the invention can also be used in one and the same process in order to maintain an even greater difference can be used between the caliber weights.
