Abstract

PURPOSE:To obtain a top comb shortening a combing process, improving removing fraction of nep, etc., and performing spinning of excellent quality by providing combs in front and rear two rows over a cylinder. CONSTITUTION:A feed comb 2, and a lower nipper 3 and an upper nipper 4 intermittently opening and closing to upper and lower directions are provided over a cylinder rotating in clockwise, and a top comb 7 having comb needles 8 of front and rear two rows is provided between a detaching roll 5 and leather 6 for conveying after nipping fed lap and combing by a cylinder comb. Removed material such as nep, etc., is cleaned by a top comb cleaner 9 engaged with a cleaner 10 made of a flat spring inserted between the top combs 7a and 7b.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a top comb which combs the wrap conveyed to the detaching roller from above in the upper part of the cylinder.

BACKGROUND OF THE INVENTION Conventionally, top combs of this type have been used which have one row of comb needles along the carding direction. (For example, see Japanese Utility Model Application Publications No. 60-56765 and No. 60-156185.) Problems to be Solved by the Invention As mentioned above, the conventional top comb, in which the working part is formed by one row of comb needles, is Since the contact with the comb needles is limited to a primary level, the neps and short fibers that are not subjected to the combing action of the comb needles or that have passed through in an evasive manner remain in the wrap (fleece) of the comb diameter. Therefore, in the conventional apparatus, it was necessary to repeat the combing process to sufficiently remove the components that need to be removed. Therefore, it has been a challenge to reduce the number of carding steps and improve the quality of spinning by increasing the efficiency of carding each time.

Means for Solving the Problems Therefore, the present invention provides a top comb that is provided above a cylinder between a nipper and a detaching roller and is provided with two rows of top combs, front and rear. .

Function As mentioned above, since the present invention is equipped with top combs in two rows, front and back, the contact between the wrap and the comb needles is reduced twice in one combing process.
It is done in stages. Therefore, even when considered simply, the removal of neps etc. is doubled and the repeated combing process can be shortened. Furthermore, since the removal rate per cycle is improved, the quality of spinning is also improved.

Example Embodiments of the present invention will be described below with reference to the drawings.

In the figure, 1 is a known cylinder that rotates clockwise in the figure and is equipped with a cylinder comb and segments (not shown) on the circumferential surface, 2 is a cylinder located at the upper left of the cylinder l, and a wrap (not shown) is attached to the cylinder 1. The upper feed combs 3 and 4 are provided in front of the feed comb 2,
Lower nipper and upper nipper that open and close up and down intermittently
Then, the plastic wrap fed from the feed comb 2 is clamped, and the tip of the protruding plastic wrap is combed by the cylinder comb. 5, following the operation of the cylinder comb, the cylinder comb is slightly reversed, the previously fed wrap is sent back a little, the wrap that has been combed by the cylinder comb is grasped between the segment that rotates next, and then the normal Detaching (bottom)
Roller 6 is an endless annular razor that conveys the lap as the detaching roller 5 rotates normally, and 7 descends when conveying the razor 6 and passes from above the latter half of the nip of a certain length through which the detaching roller 5 and the razor 6 convey. Top comb.

This top comb 7 is a pair of front and rear top combs 7 in which comb needles 8 are arranged in two rows, front and rear, as shown in the figure.
a and 7b. A comb cleaner 9 is interposed between the top combs 7a and 7b in the two front and rear rows, and has cleaners 10 made of leaf springs that protrude in the two front and rear directions and engaged with the two rows of comb needles 8 in the front and rear, respectively. When the top comb 7 is raised, the removed matter caught on the comb needle 8 is cleaned.

In the figure, 11 is a delivery roller for receiving and taking the wrap A from the leather 6, and 12 is a trumpet for forming the wrap A into a sliver.

Top combs 7a are provided in two rows, front and rear, as described above.

7b and comb needles 8, the lap is combed by two stages of top combs 7a, 7b when forming one nip.

Effects of the Invention As described above, the present invention is equipped with top combs in two rows, front and rear, and the wrap is combed by two stages of comb needles every time one nip is formed. This is carried out sufficiently every time the carding is carried out, which has the effect of shortening the carding process and improving the quality of the spinning.
