A protruding shank 35 is disposed above the head 31. A cutting edge 351 is disposed at the front end of the shank 35, and the shank 35 is brought close to the shank 35. Appropriate position of the blade 351 is moderately bent in the direction of the slab 2, so that the blade 351 of the dicing blade 3 can be more closely attached to the slab 2, and the blade edge 352 of the blade 351 is turned from the top to the bottom. The end of the shank is formed with a vacant space 36 between the shank 35 and the head 31; the shank 35 of the dicing sheet 3 corresponds to the nose 25 of the slab 2, and the guide groove of the dicing sheet 3 34 and raw grams The guide grooves 24 of the sheet 2 are of the same width, and the legs 33 of the cut sheet 3 are slightly wider than the legs 23 of the raw sheet 2; the inner surface of the upper braided triangle 4 is provided with protrusions and curved The irregular track 41 is provided with a positioning groove 42 on the front portion of the track 41, and a positive and negative block 43 is mounted on the outer end surface of the tail section 41 of the upper braiding triangle 4; A sliding slot 441 is defined in the extension plate, and all the yarn blocks 45 are installed in the sliding slot 441.

With the above-mentioned components, when the creation is in operation, the syringe 1 is connected to the sprocket 14 in a rotating state, and the movement of the knitting needles 12 is controlled by the knitting triangle 6 provided on the inner surface of the lower saddle 7. The action of the upper and lower hook yarns can be performed, and the slabs 2 and the cut yarns 3 are placed in the sliding grooves 141 of the scotch disc 14 with the sliding portions 22 and 32 at the bottom ends thereof, and are set. The track of the braided triangle 4 on the bottom end of the upper base 5 falls into the guide grooves 24, 34 of the slab 2 and the cut yarn 3, enabling the driving of the slab 2 and the cut yarn 3 The action of the rear displacement.

When the creation of the creation of the knitting action, please refer to the eighth figure is a schematic diagram of the continuous action of the creation. First, when the hook 121 of the upper end of the knitting needle 12 in the cylinder 1 is ascended to the upper position of the nose 25 of the slab 2, the slab 2 and the dicing sheet 3 are kept attached to each other. The front running, that is, the cutting edge 352 of the cutting yarn 3 does not exceed the blocking portion 252 of the nose 25 of the raw sheet 2 and the guide ring tongue 251. At this time, the knitting needle 12 is hooked by the hook 121 from top to bottom. When the yarn is lowered to the lower end surface of the hook groove 26 of the slab 2, a new loop 8 is formed, and at the same time, the old loop 8 formed by the previous weaving is set on the slab 2 The guide ring 251 of the nose 25 is matched with the blocking portion 252 to define the old loop 8 to ensure the tightness and identity of each loop 8 after knitting, thereby enabling the hair to be flattened after cutting. In the foregoing process, the cut yarn sheet 3 does not participate in the work, and only follows the synchronous operation of the raw sheet 2, at which time the raw sheet 2 and the cut sheet 3 are moved to the position of the extension plate 44 of the upper braided triangle 4 ( Please refer to the seventh figure). Since all the yarn blocks 45 are provided on the extension plate 44, and the inner end surface of the cutting yarn block 45 is provided with a wedge-shaped convex portion, the outer end of the track 41 will be made. The distance from the inner end surface of the dicing block 45 is gradually reduced, and the leg 33 of the dicing sheet 3 is slightly wider than the leg 23 of the slab 2, whereby the dicing sheet 3 travels to the track 41. At the same time, by the pushing of the cutting block 45, the cutting piece 3 will be forced to move forward abruptly, and at the same time, the leg 23 of the slab 2 is not narrow with the cutting yarn. The block 45 forms an interference which still maintains a predetermined trajectory, so that a relatively shearing effect is formed between the dicing sheet 3 and the slab 2 so that the guide ring 251 of the slab 2 can be placed The loop 8 is cut (i.e., the blade edge 352 on the cut sheet 3 advances beyond the blocking portion 252 of the nose piece 25 of the slab 2 and the guide ring tongue 251) to form the wire end 81, and then the needle 12 is formed. The slab 2 and the cut yarn 3 are immediately reset, waiting for the knitting operation of the next cycle.

The shearing action of the cut yarn piece 3 opposite to the slick sheet 2 is such that the shank 35 of the cut yarn piece 3 is appropriately bent in the direction of the slab 2 at a position close to the blade 351, so that the cut piece is cut. The blade 351 of 3 is more closely attached to the slab 2, so that a better shearing effect can be produced, and since the blade edge 352 of the blade 351 of the dicing blade 3 is inclined downward, during the process of cutting the loop 8, With the cutting of the crepe sheet 3, the blade 352 will form a "linear" cutting effect on the loop 8, which is more stable than the conventional "dot" cutting, and due to the cut sheet A vacancy 36 is formed between the shank 35 and the head 31, and the gap of the vacancy 36 is larger than the hook groove 26 of the slab 2, so that when the dicing sheet 3 and the slab 2 are combined and woven During the knitting operation of the needle 12, during the formation of the loop 8, the loop 8 has a process of pulling down the hook 121 of the needle 12, which avoids the gap between the loop 8 and the cut sheet 3. Friction is created to ensure smooth running of the entire weaving process.

It is worth mentioning that the cutter bar 35 of the aforementioned cut yarn piece 3 has an angle of inclination of the blade edge 352 at the front end from the top to the bottom, and is continuously studied, experimentally and adjusted by the creator, and is 20 to 55 degrees. The range is the tilt angle of the best shearing effect.

By the above-mentioned structure and operation mode, the present invention can surely achieve the high-efficiency work done by knitting the terry cloth surface and the shearing, and can make the length of the yarn after the shearing uniform, reduce the loss, save the cost, and facilitate the creation. Higher economic efficiency, and since the upper braiding triangle 4 is provided with the positive and negative masses 43 and the cut yarn block 45, the positive weave knitting can be arbitrarily changed by adjusting the position of the forward and reverse masses 43. The type of the reverse wrapping, and by adjusting the position of the cutting block 45, the cloth surface shape of the shearing or non-cutting can be selected, so that a variety of different types of knitting effects can be achieved by mutual blending, which is one of the original creations. Great feature.
