常時一定の空〓を有する。 In FIG. 2, the grooved roll 5 is a roll with an outer diameter of 200 mm and has two types of grooves, ie, support grooves 5a and passage grooves 5b, which alternately have different groove depths. It is a roll that rotates due to contact friction force. The thread 1a threaded through the support groove 5a is lifted from below to above by the support groove 5a, so the support groove 5a and the thread 1a are constantly rotating in contact with each other. The thread 1b inside is smaller than the diameter of the passage groove 5b.
Since the groove width W 2 is wider, it does not contact the groove wall,
It always has a certain amount of emptiness.

りも大であれば良い。なお、ｈは、特に限定され
ないが、５〜100mmとするのが好ましい。 The grooved roll 5 having such two groove depths narrows the pitch between yarns in order to increase the number of yarns to be threaded as much as possible, and prevents contact and entanglement between adjacent yarns. The supporting groove width W 1 is preferably 1 to 10 mm, although the dimensions of each part are not limited.
Passing groove width W 2 is 5 to 15 mm, support groove thickness W 3 is 3
~15mm, and in this example, 5mm and 15mm, respectively.
10mm, 10mm. Also, the groove depth H of the passage groove 1b
should be larger than the inter-yarn distance h between the yarns 1a and 1b created when the yarn 1a is lifted from below to above by the support groove 5a. Note that h is not particularly limited, but is preferably 5 to 100 mm.

ルを設けることが好ましい。 In this embodiment, the grooved roll 5 has two types of groove depths, but it is also possible to cut the grooves in three or four levels. However, in this case, if you try to split the yarn into multiple stages with a single grooved roll, the relative speed at the bottom of the groove will vary depending on the depth and fluff will occur, so multiple grooved rolls are provided corresponding to the number of stages. It is preferable.
溝付きロール５の材質は、通糸糸条に毛羽を発
生させず、発錆の恐れがないものならば特に制限
はないが、表面にセラミツクコーテイング、メツ
キ処理などが施されていることが好ましい。 The material of the grooved roll 5 is not particularly limited as long as it does not generate fuzz on the threaded yarn and there is no risk of rust, but it is preferable that the surface be ceramic coated, plated, etc. .

The means of transportation is
Any moving means that supports the shaft of the grooved roll 5 and moves it up and down is known, for example,
An actuator using an air cylinder, hydraulic pressure, mechanical force, etc. may be used.
なお、該溝付きロール５の配設位置は、供給ロ
ール４と焼成炉６中の焼成部（糸条が焼成される
部分）との間、および、引取ロール７と焼成炉６
中の焼成部との間であれば良く、焼成炉６の外に
あるか内にあるかは問わない。 The grooved roll 5 is installed between the supply roll 4 and the firing section (the part where the yarn is fired) in the firing furnace 6, and between the take-up roll 7 and the firing furnace 6.
It does not matter whether it is outside or inside the firing furnace 6, as long as it is between it and the firing section inside.
焼成炉５は、公知のものであればいずれであつ
ても良く、特に限定されないが炉長500〜2000mm、
処理温度300〜3000℃からなる水平配置のもので
あり、その後部に配置されている引取ロール７
は、前記供給ロール４と同様のものである。 The firing furnace 5 may be any known one, and is not particularly limited, but has a furnace length of 500 to 2000 mm,
It is horizontally arranged and has a processing temperature of 300 to 3000℃, and the take-up roll 7 is placed at the rear.
is similar to the supply roll 4 described above.
次に、このように構成された本装置の作用を再
度、第１図と第２図を用いて説明する。 Next, the operation of the apparatus configured as described above will be explained again using FIG. 1 and FIG. 2.
供給ロール４から水平一列状に供給された糸条
１は、該溝付きロール５が前記エヤーシリンダで
下方から上方へ持ち上げられるので、支持溝５ａ
の上にある糸条１ａのみが、該支持溝５ａと共に
上方へ持ち上げられる。 Since the grooved roll 5 is lifted from below to above by the air cylinder, the yarn 1 supplied in a horizontal line from the supply roll 4 is moved into the support groove 5a.
Only the thread 1a located above is lifted upwards together with the support groove 5a.
一方、通過溝５ｂの上にある糸条１ｂは、該通

記糸条間距離ｈよりも通過溝深さＨの方が深いの
で、従来位置のままである。よつて、糸条１は、
焼成炉６中で上下２段に糸条間距離ｈで分繊され
る。 On the other hand, for the yarn 1b above the passage groove 5b, the passage groove width W 2 is larger than the yarn diameter, and the passage groove depth H is deeper than the inter-yarn distance h. , remains in its conventional position. Therefore, yarn 1 is
In the firing furnace 6, the fibers are divided into two stages, upper and lower, with a distance h between the yarns.
このように、炉内通糸糸条を２段配列としたこ

配列ピツチに比べ、通糸総本数が変らないにも拘
らず２倍の広さのピツチが確保し得る。 In this way, by arranging the yarns passing through the furnace in two stages, the pitch between the yarns 1a supported by the support groove 5a and the yarn 1b passing through the passage groove 5b are reduced. The pitch between the threads can be twice as wide as the conventional pitch arranged in a single row, even though the total number of threads remains the same.
