CIRCULAR KNITTING MACHINE
A circular knitting machine includes lower bricks, guiding elements attached to the lower bricks and formed with a guiding groove extending like the profile of a peak, needles, upper bricks, hooks movably connected to the upper bricks. Each of the needles includes a rear edge, a front edge, a body extending from a head to a tail, and a fin extending from the body and being movable in the guiding groove of a related one of the guiding elements so that the needle is movable up and down relative to the guiding elements as the needle is movable around the guiding element. The head of each of the needles includes a first inclined edge extending downward from the rear edge, a second inclined edge extending toward the rear edge while extending downward from the first inclined edge, and a recess defined between the second inclined edge and the front edge.

1. Field of Invention
The present invention relates to a circular knitting machine and, more particularly, to a needle and guiding element of a circular knitting machine.
2. Related Prior Art
Referring to
The jersey 100 however cannot be knit by any conventional circular knitting machine. Therefore, there is a need for knitting a jersey such as the jersey 100.
SUMMARY OF INVENTIONIt is the primary objective of the present invention to provide a circular knitting machine for knitting a jersey with two patterns each formed amid a background formed on a related one of two sides so that the color of the pattern on the first side of the jersey is the color of the background on the second side of the jersey, and that the color of the background on the first side of the jersey is the color of the pattern on the second side of the jersey.
To achieve the foregoing objective, the circular knitting machine includes lower bricks, guiding elements, needles, upper bricks and hooks. The lower bricks are arranged along a circle. Each of the guiding elements is attached to a related one of the lower bricks and formed with a guiding groove extending like the profile of a peak. Each of the needles includes a head, a tail, a body extending from the head to the tail, and a fin transversely extending from the body. The body includes a rear edge and a front edge. The fin is movable in the guiding groove of a related one of the guiding elements so that the needle is movable up and down relative to the guiding elements as the needle is movable around the guiding element. The upper bricks are arranged along a smaller circle. The hooks are movably connected to the upper bricks. The head of each of the needles includes two inclined edges and a recess. The first inclined edge extends downward from the rear edge. The second inclined edge extends toward the rear edge while extending downward from the first inclined edge. The recess is defined between the second inclined edge and the front edge.
Other objectives, advantages and features of the present invention will be apparent from the following description referring to the attached drawings.
The present invention will be described via detailed illustration of the preferred embodiment referring to the drawings wherein:

The internal bank of the guiding groove 21 includes three sections. The first section 21d of the internal bank of the guiding groove 21 extends from another section of the lower side 24 of the guiding element 2. The second section of the internal bank of the guiding groove 21 extends substantially parallel to the second section 21b of the external bank of the guiding groove 21. The third section of the internal bank of the guiding groove 21 extends parallel to the third section 21c of the external bank of the guiding groove 21.
The guiding groove 21 includes an inlet 22 and an outlet 23. The inlet 22 is located near a leading end 26 of the lower side 24 of the guiding element 2. The outlet 23 is located near a tailing end 25 of the lower side 24 of the guiding element 2. The inlet 22 is defined by and between the first section 21a of the external bank of the guiding groove 21 and the first section 21d of the internal bank of the guiding groove 21. The inlet 22 is shaped like an inverted funnel for effectively guiding the fin 14 of a needle 1. The outlet 23 of the guiding groove 21 is defined by and between the third section 21c of the external bank of the guiding groove 21 and the third section of the internal bank of the guiding groove 21.
