S.440. On which plate are single plate knits produced?
C.440. Single plate knits, as the name suggests, are knits obtained only on the front plate or only on the back plate.
S.441. One of the most important settings in electronic flat knitting machines is machine speed. If the speed is low or fast, how will it affect the production, knitting and auxiliary elements of the machine?
C.441. The most important setting in electronic flat knitting machines is the machine speed setting. If the speed is set low, the production capacity will also decrease. However, even if it is operated too fast, the knitting and auxiliary elements of the machine may be damaged..
S.442. One of the most important settings in electronic flat knitting machines is the arbor setting. What are the consequences if the wrong setting is made?
C.442. Arbor setting is very important in the production of single plate knits. If it is done incorrectly, it will cause defects on the surface of the single plate weaves. Small meshes appear in one loop of the piece knitted with one tight and the other loosely adjusted arbor, and larger meshes appear in the other loop. The image of the part looks like stripes.
S.443. Electronics According to which factors the settings differ in flat knitting machines, explain?
C.443. In flat knitting machines, the settings vary according to yarn fold, machine fineness and knitting type. If it is necessary to knit one single plate and the other full needle in the same yarn ply on the same machine, the loop length setting of the single plate knitting should be higher, this difference varies according to the thickness of the machine. Since the loops are connected side by side in single plate knitting, the distance between the loops becomes shorter. When adjusting the loop lengths, comparison is made with the sample at hand.
S.444. Electronics In flat knitting machines What is the effect of the roller draft setting on the formation of the weave, please explain?
C.444. Roller draft setting is very important in the formation of the weave. Shooting should be regular in single plate knits. Otherwise, the roller draft differences that may occur become more evident in single-plate knits. The draft varies according to the thickness of the machines, the number of working systems in the knitting and the characteristics of the knitting.. For example, if we think that we knit a tight gauge knit with a single system on a 12-number machine, we get a 1,5 – 2 mm knit with one movement of the head. If we use too much draft here, this excess roller draft value will damage the fabric and needle tongues. When we consider the opposite situation; When you knit an open gauge knit with a 3 number machine and 2 systems, we can obtain 2-2,5 cm knitting in one head movement. In such a case, a low roller draft value may cause the knitted fabric not to shrink and accumulate on the needles. Our knitting and needles are damaged. Considering these, an average attraction value is given. This shrinkage value can be increased or decreased during the knitting process by controlling it manually and visually while knitting. In addition, with the help of the pressure rollers on the roller, we can increase or decrease the drafting effect by giving the desired pressure to the desired area of the knitting area.
The main roller of flat knitting machines is covered with rubber. Prints are hard plastic. In addition to the main draw during knitting without changing the print settings, there are also side draws that are applied only to the edges of the weave. These shots vary according to the manufacturers.
S.445. Electronics In flat knitting machines Which machine element pulls the knitting from the needles to the main roller?
C.445. Comb
S.446. Electronics In flat knitting machines, by which method is it brought down from the knitting needles to the main roller?
C.446. From the knitting needles to the main roller, it is brought down by knitting with waste yarn or piece fastening method.
P.447. How to produce Corded Knitted Fabric, what kind of settings are made, what are the reasons, please explain?
C.447. Ribbed braids are obtained by knitting on the front and back plate. However, during this knitting process, the back plate opposite the knitting needles on the front plate does not knit, in the same way, the needles on the front plate corresponding to the knitting needles on the back plate do not knit.. However, in solid needle roving knitting, only the needles on the front or the back of the plate knit, and certain needles do not knit. On the other hand, all the needles on the opposite plate are knitting. The pattern program of the roving knitting, which is prepared in the pattern computer, is loaded into the machine through the appropriate method.
While working on the sample, the length adjustment should be made exactly according to the number of may and needles.. Since there will be more stretching than width in corded knits, it is usually done over the number of rovings when adjusting. Length adjustment is made over the number of may.
While preparing the needle area on the plate, the needle values on the left and right edges are checked from the program. It is checked whether there is a piece of knitting in this needle range.. Since there is no drafting system that pulls the knitting we call comb up to the main roller in the old type machines, a different piece of knitting is attached to the needles with 2-3 needle intervals to ensure that the new knitting is pulled. Thus, the knitting area is prepared. In new type machines, the starting and ending needle spacing is directly lowered to the main roller with the help of a comb, and the knitting area is prepared.
The shuttles running in the pattern program of the roving knitting are checked. Positioned close to the knitting area. The purpose of positioning close to the knitting area is to increase the production speed by allowing the head of the machine to return without going beyond the knitting area in turns.
As in all weaves, the gravitational force should be applied equally to all parts of the weave in corded weaves.. Otherwise, sagging and deformities can be seen in the knitting.
In corded knits, the yarn layer is determined according to the thickness of the knitting sample. After the machine thickness is determined according to the condition of the yarn layer, the yarns are tied according to the shuttles to be used on the program.. In the adjustment of the loop lengths, the settings are made by taking into account the machine thickness and the yarn layer. In corded knitting, the front plate and back plate are given the same value may setting. In addition, the positions of the needles on the front and back plate should be adjusted in corded knitting. The positions of the needles should only be adjusted so that they are head-to-head during cord knitting. With this adjustment, the yarn transition intervals of the knitting area on the front plate and the knitting areas on the back plate are equal to each other. The zero position of the needle plates and the reciprocal positions of the needles are shown below. In the zero position of the needles, the thread transition length between the back plate and the front plate on the left is shorter, and the thread length between the needles on the right is longer. Due to this difference, an even image is not formed in the knitting. However, in the case on the left side and the needles are opposite, it is seen that the thread transitions are equal. It is necessary to pay attention to this situation when knitting the knitting..
The needles cannot be adjusted mutually in corduroy knitting with full needles. In corded knits without a full needle, the needle plate should be adjusted as the needle position on the left side below.
In order for the surface of the roving knitting to appear smooth, the arbor settings should be adjusted equally on the knitting machines. In addition, it should be ensured that the yarns are fed with equal tension to the knitting area by using firniers. When the yarns fed at equal tension and the may settings are written correctly in the program, samples can be knitted without any problems.
These are the settings that need to be made in order for the machine to work flawlessly during the knitting of the corduroy. These settings can be edited on the program. The working speed of the machine may be faster in corded knitting than in solid needle knitting. Because the speed can be increased as the number of needles working at the same distance decreases. Care is taken to ensure that the settings are at the most appropriate value for the machine and the product.
The pattern program of the roving knitting is first tested by the pattern computer program. Then the tested program is loaded into the machine. After it is loaded on the machine, this time it is tested on the machine and the correctness of the program is checked and the sample is made ready for knitting.
The knitting process of the roving knitting program, whose test process is completed, is done.. In order for the machine to start knitting after the command is entered, the knitting process is started by lifting the arm of the machine. During the knitting process, the formation of the knitting is monitored and controlled at the machine.
The test piece, the knitting process of which has been completed, should be compared with the sample and corrections should be made if any.. In roving knitting, the weave is gathered in the transverse direction due to the opposite effects of the rovings. In this case, the test piece is ironed so that the measurement can be taken correctly, the surface tensions are fixed and the piece is kept at a constant width. After the ironing process, the number of wicks is checked to adjust the width on the piece. The roving count of the front plate loop bar and the back plate loop bar counts as one roving. Piece length is measured when the piece is rested, ironed or washed in open space.
The second test covers the process of applying all the changes made on the first test piece to the program and performing a test run again.
Q.448. In which plates are roving braids produced, please explain?
C.448. Ribbed braids are obtained by knitting on the front and back plate. However, during this knitting process, the back plate opposite the knitting needles on the front plate does not knit, in the same way, the needles on the front plate corresponding to the knitting needles on the back plate do not knit.. However, in solid needle roving knitting, only the needles on the front or the back of the plate knit, and certain needles do not knit. On the other hand, all the needles on the opposite plate are knitting.
S.449. How should the gravitational force be in corded knits?
C.449. As in all weaves, the gravitational force should be applied equally to all parts of the weave in corded weaves. Otherwise, sagging and deformities can be seen in the knitting.
