DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a French comba used for very long fibers such as flax and hemp in the textile industry, and in particular, to a saber or scatcher provided in such a machine and a counter counterpart thereto. It relates to sabers or counter scatchers.

Each of these scatchers and counter scatchers is a sword-shaped member, and the scatcher cooperates with the counter scatcher to push down the rear end of the sliver while pressing the sliver against an endless belt, thereby forming a subsequent combing cycle. The fiber sheet is positioned so that the sliver acts so as not to be gripped again by the circular comb, and the sliver is joined well.

[0003]

2. Description of the Related Art Combs for wool and long fibers usually have a pneumatic scutter device which performs the functions of these and counter scutters on the combed fiber sheet by means of a suction system. However, this pneumatic scatcher does not work effectively when processing very long fibers and requires the use of mechanical scatcher and counter scatcher devices.

The general function of such an apparatus is that when the belt is retracted, the scatcher and the counter scatcher cooperate with each other to complete the stripping of the longest fiber while drawing the fiber sheet. The counter scatcher presses the fiber sheet against the lower stripping cylinder at the stage where the lower stripping cylinder around which the belt is disposed rotates in the stripping direction, and holds or adjusts the fiber sheet.

[0005]

In the existing scatcher and counter scatcher device, the descending stroke of the support arm for supporting the scatcher is limited at the position where it comes into contact with the stripping cylinder. Stripping cannot be performed completely or sufficiently.

An object of the present invention is to eliminate the above-mentioned disadvantages,
An object of the present invention is to provide a scatcher and a counter scatcher device for a very long fiber Buddha-style comber, which can lower the scatcher over a long stroke, and thus can reliably and sufficiently strip very long fibers. .

[0007]

SUMMARY OF THE INVENTION According to the present invention, an object of the present invention is to provide a scuffer and a counter scutterer for a French-style comb for very long fibers, comprising a pair of stripping cylinders and a pair of stripping cylinders. And a stripper carriage that rotatably supports a stripping cylinder, and that is reciprocally movable toward and away from a nipper that grips a sliver of extremely long fibers. A scatcher that descends in conjunction with the stripping carriage to push down the rear of the sliver, and a counter scatcher that rises to support the rear of the sliver in cooperation with the scatcher while the scatcher is descending. , Greatly increases the descending stroke of scatcher and enables stripping of extra long fibers A scuffer for a French-style comba for very long fibers, wherein the scuffer is connected to a stripping carriage via a support arm which is located below the stripping cylinder and the stripper belt and is curved so as to project downward. Achieved by a counter scatcher device.

According to the scuffer and the counter scatterer of the French-style comb for very long fibers of the present invention, the support arm connecting the scutter to the stripping carriage is curved so as to project downward, and the stripping cylinder is provided. And because it is located below the stripper belt,
The stroke of the descending movement of the scutcher in conjunction with the stripping carriage can be greatly increased, enabling stripping of extremely long fibers. Therefore, the stripping ability of the comber can be improved, and the stripping can be sufficiently and favorably performed on a wide range of fibers from a normal length fiber to an extremely long fiber. In addition, since the scatcher can be completely removed from above the apparatus main body, it is possible to easily attach and detach various accessories for improving the quality of the fiber sheet.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to preferred embodiments shown in the drawings.

The comb for extra long fibers of the present invention shown in FIGS. 1 and 2 as a non-limiting example is provided with a saber 2 as a scatcher and a counter saber 3 as a counter scatcher. In order to significantly increase the descending stroke of the saber 2 and improve stripping of very long fibers, the support arm 8 of the saber 2 has a downwardly convex curve and a stripping cylinder 4.
And is located below the stripper belt 6.

The saber 2 and the counter saber 3 are configured to move up and down in conjunction with the reciprocating rotation of the stripping carriage 9 respectively.

With this configuration, the support of the stripping cylinder 4 can be improved. This is because the pivot portion of the saber 2 is at the lower position and does not hinder the support when the saber is lowered. Further, since the saber can be completely removed from above the stripping device, it is possible to easily attach various accessories for improving the quality of the fiber sheet.

Increasing the stroke of the saber increases the stripping capacity of the comber and extends the range of application from regular length fibers to very long fibers, so that combers equipped with such devices have higher efficiency. And a wider range of use.

FIG. 1 shows the apparatus of the present invention when the saber 2 is in the lower position and forms the deflector necessary to complete stripping of the longest fiber.

In FIG. 2, the saber 2 is in the upper position, and the fixed comb 7 is removed while stripping the rear end of the fiber sheet.
Can pass through.

The sliver-like material 1 is introduced by the feed comb and is gripped by the nipper during the stripping of the fiber sheet front end by the comb of the comb.

In this step, as shown in FIG. 2, the saber 2 is in the upper position and the counter saber 3 is in the lower position.

After the front end is stripped, the stripping cylinder 4 moves the stripped sheet 5 onto the stripper belt 6. At this stage, saber 2 and counter saber 3 form a deflector to complete stripping of the longest fiber (FIG. 1).

When this operation is completed, the saber 2 is raised and the counter saber 3 is lowered so that the fixed comb 7 can pass through, and the fixed comb strips the fiber rear end. Thereafter, the fixed comb 7 is raised and the saber 2 and the counter saber 3 and the stripping cylinder 4 are positioned to start a new cycle.

The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the present invention, particularly for each component or by using a similar technique.

[0021]

As described above, according to the scatcher and the counter scatcher device of the French type comb for very long fibers of the present invention, the scatcher can be lowered over a long stroke, so that stripping of extremely long fibers can be performed. It can be performed reliably and sufficiently.
