Multi-function Circular Knitting Machine Introduction

Especially for circular weft knitting machine, circular knitting machine are required to have multi functions. A circular knitting machine can knit various products without being changed or spending too much time changing spare parts. On one hand, the categories of knitted products change frequently. For that, manufactures must adapt to the changes in the market constantly, providing products to meet the demand without putting into more equipments or funds. On the other hand, the prices of new type knitting machine are increasing. The machine being used to knit only one category cannot give full play to its investment benefits.

Multi-function circular knitting machine means that a type knitting machine can change into similar type machine rapidly through standardization, generalization of parts.

1.Exchange between single knitting machine and double knitting machine
In general, single knitting machine needs sinker to assist needle clearing and bending yarns into circular. However, it is difficult for conventional double knitting machine knitting rightly without sinker when it is used to knit single fabrics. Currently, there are two solutions. One is that double knitting machines are equipped with channeling triangle. When top needles are knitting, upper needles erect outside and return before yarn laying. The top needles are regarded as sinker pressing on the old loops of lower needles when bottom needles rising for clearing in case of old loops rising with needle. The other one is more effective solution. Double knitting machine is equipped with sinker to assist needles looping. So, when the machine is knitting double fabrics, the needles initiate automatically without dossal. The machine can recover knitting easily if press-off happens or large hole appears. When it is knitting single fabrics, the machine can utilize sinker to assist needle clearing and bending yarns into circular just like single knitting machine to realize the exchange between single knitting machine and double knitting machine.

2.Exchange of structure of single knitting machine
Based on different categories of knitted fabrics, single knitting machine is classified into single plain knitting machine, three wire wool knitting machine and single terry machine. Track, triangle and other parts have realized standardization and generalization. Parts on those types knitting machine provided by different manufacturers can be changed easily from one type to another type. An engineering technicians only spends 2 hours or 3 hours completing exchange.

3.Exchange of double knitting machine
Double circular knitting machine is generally classified into rib knitting machine and interlock machine. According to different structure of triangle, changing the position of triangle can converse rib or linter, rib composite tissue or linter composite tissue, such as Milano rib, polyester cover cotton and honeycomb mesh. Besides the exchange between rib and linter, multi-function double circular knitting machine can also exchange different tissues to change categories easily.

To adapt the conversion, multi-function double circular knitting machine is added with channeling triangle, besides conventional looping, tuck stitch and loose stitch. Sync or lag stitch cam is caused during looping. When channeling triangle is used for knitting single fabrics, stitch cam on cylinder uses sync or lag stitch cam to knit linter or wide rib.

4.Exchange of number and path
Using the same circular knitting machine can knit fabrics with different thickness for seasons. Changing number is meaningful for manufacturers. To meet the demands of fabric producers, manufacturers have simplified the exchange of cylinder and dial. For example, when transforming X-pattern track into V-pattern track, cylinder should be replaced from top. Now, the cylinder can be replaced from side without disassembling machine. Triangle and yarn guide do not need to be replaced, when interlock machine changed between E18~E28.
