Abstract

Knitting machines for producing flush fabrics include latchless cylinder needles in the cylinder, latch needles located on the needle dials, and a cutting unit. The annulus formed by the flush yarn is knitted directly to the fabric formed by the ground yarn to form a longer flush on the fabric surface. By varying the dimension of the needle dial, the spacing between the circumferential edge of the needle dial and the cylinder needle can be increased, so that the flush seal caught on the hook of the cylinder needle can be elongated by the latch needle, resulting in longer deflection. Finally, the knitting is cut by the cutting unit to form a longer flush flush fabric.

FIELD OF THE INVENTION The present invention relates to circular knitting machines, and more particularly to knitting machines for the manufacture of flush fabrics with longer flushes.

In general, plush fabrics are produced by knitting machines, also called artificial wool knitting machines. Techniques for using circular knitting machines to produce flush fabrics are known in the art. For example, US Pat. No. 6,735,987 has latch needles and a number of sinkers located in a cylinder, where a number of sinkers are horizontally located on the needle dial and to form a longer shift. They will interact with each other to keep plush threads at the front edge of the sinker.

U.S. Pat.Nos. 6,128,930, 6,094,944 and 5,463,882 basically include latchless cylinder needles located in a cylinder, latch needles located in a needle dial, and a cutting unit, and they interact To produce a flush fabric. The deflection is formed on the hooks of the latchless cylinder needles, which are cut by two sinkers that have blades on the front side and slide on both sides of the cylinder needles to form a flush.

In US Pat. Nos. 6,128,930 and 5,463,882, the length of the flush is determined by the distance between the hook of the cylinder needle and the needle dial edge. In general, the flush fabrics produced by such techniques have a flush length of about 3 mm. Toys and dolls are made from artificial fur or felt, which cannot be realized with a 3mm flush length. To increase the flush length, the hook between the needle of the cylinder needle and the needle dial edge must be larger. This can be accomplished by increasing the diameter of the cylinder. In addition, a sinker ring that holds the blades around the cylinder should also have a larger diameter. As a result, the relative position and dimensions of the blade and the cylinder needle must be changed. This results in a larger gap between the blade and the cylinder needles, making it difficult or impossible to cut off the ring.

It is therefore a first object of the present invention to provide a knitting machine for producing flush fabrics, in particular a flush knitting machine for producing flushes up to 12 mm in length.

According to an embodiment of the present invention, the flush knitting machine includes a latchless cylinder needle located in the cylinder, a latch needle located horizontally in the needle dial, and a cutting unit. The distance between the circumferential edge of the needle dial and the cylinder needle can be increased by changing the dimension of the needle dial. If the flush seal forms a hook on the hook of the latchless cylinder needle, the latch needle of the needle dial will elongate the flush seal to form a longer hook. Finally, the cutting unit cuts the declination to form a flush fabric with a longer flush.

Additional features and advantages of the present invention as well as the above-described features and advantages will be more readily understood from the following detailed description with reference to the accompanying drawings.

Referring to Figure 1, the circular knitting machine has a knitting unit that produces a flush fabric, that is, transforms the yarn into a fabric.

Embodiments of the present invention include: a latchless cylinder needle 11 located in the cylinder 10, a latch needle 21 located in the needle dial 20, and a cutting unit 30. The cutting unit 30 includes two sinkers 31 and 32 and a cam 33 formed in one set (see FIG. 2). The sinkers 31 and 32 are driven by the cams 33 to slide simultaneously on both sides of each cylinder needle 11. The sinker 31 has a blade 310 which can be cut so that the uneven 41 formed by the flush seal 40 becomes a long flush (see FIG. 3).

According to this embodiment, the dimension of the needle dial 20 is changed so that the distance D between the circumferential edge 22 of the needle dial and the first hook 112 of the cylinder needle can be increased to 10 to 15 mm. Can be. Thus, the flush seal 40 held in the first hook 112 can be extended by the latch needle 21 to form a longer unwind 41. Finally, the cutting unit 30 cuts the unwind 41 to form a flush fabric having a flush length of up to about 12 mm.

For the manufacturing process for producing the flush, reference is made to FIGS. 4 to 7. First, a flush seal 40 is supplied between the front edge 110 of the cylinder needle and the second hook 210 of the latch needle, and the rear end 111 and the circumferential edge 22 of the needle dial (Fig. A ground thread 50 is supplied between them; While the latch needle 21 is moved to the left (see FIG. 5) and retracts, the cylinder needle 11 is raised so that the first hook 112 is raised to an elevation that the flush seal 40 can take. Begins to move upwards; The flush seal 40 is caught by the second hook 210 of the latch needle and is held in the first hook 112 of the cylinder needle to form a ring 41; The latch needle 21 keeps contracting to raise the ground seal 50 and send it to the inclined surface 23; The latch needle is guided by the inclined surface 23 and gradually moved below the second hook 210; Then, the ground seal 50 is moved under the flush seal 40 (see FIG. 6); Thereafter, the cylinder needle 11 moves downward to elongate the deceleration 41 through the first hook 112. Thus, through the interaction of the cylinder needle 11 and the latch needle 21, the ring-shaped 41 formed by the flush seal 40 can be knitted directly to the fabric formed by the ground seal 50. Finally, the declination 41 can be cut by the cutting unit 30 to form a flush fabric with a longer flush.

As mentioned above, the knitting machine for producing a flush fabric according to the present invention can produce a flush fabric having a longer flush.
