が一般的である。(Prior art) In a long-fiber nonwoven fabric production device in which a group of undrawn filaments from a spinning head are sucked and stretched by an ejector and laminated on a collection surface to form a web, manufacturing steps are required to obtain a nonwoven fabric of a certain width. Generally, ejectors are arranged in a direction perpendicular to the traveling direction of the web collection device over the entire width of the nonwoven fabric.

エクターを取り付ける技術も、例えば特開昭57−
42954号公報に開示されている。 In addition, in order to stabilize the spinning condition, a technique has been proposed, for example, in Japanese Patent Laid-Open No. 57-1991, which provides a plurality of spinnerets in the width direction of the web and attaches an ejector to each spinneret.
It is disclosed in Publication No. 42954.

した後、使用にあたり希望の巾に切断するといつ
た方法が考えられる。 By the way, if you want to change the width of the nonwoven fabric during the manufacture of the nonwoven fabric, you will have to install multiple spinnerets and install different devices for the width of the nonwoven fabric, each with a different ejector width. For example, it is possible to use a device with an ejector at both ends to stop the supply of molten polymer to the spinnerets at both ends to form a web of the desired width, or to form a nonwoven fabric and then cut it to the desired width for use. It will be done.

ところが、前記した方法において、では投資
額が膨大となり、ではある程度の巾の調整は可
能であるが、巾の細かい調整まではできない、
では切断によるロスが生じる場合があるという問
題点があつた。(Problems that the invention aims to solve) However, with the method described above, the investment amount is enormous, and although it is possible to adjust the width to a certain extent, it is not possible to finely adjust the width.
However, there was a problem that loss may occur due to cutting.

布製造装置を要旨とするものである。(Means for Solving the Problems) That is, the present invention provides a method for producing a long fiber nonwoven fabric by laminating a group of filaments from a spinning head on a collection surface to form a web, in which the spinning head is divided into a plurality of parts. The gist of the present invention is an apparatus for producing a long fiber nonwoven fabric, which is characterized in that a metering pump is individually installed at each spinning head.

織布を製造することができるのである。 The apparatus according to the present invention has a plurality of spinning heads, each of which is equipped with a metering pump, and is configured to be able to individually change the discharge amount. When obtaining a narrow-width non-woven fabric, a nozzle plate with no nozzle holes is installed near the ends of the spinning heads at both ends, and the discharge amount can be changed accordingly to produce a non-woven fabric of any width. It is.

functions to suck and stretch a group of filaments spun from a spinning head 2 in which spinning holes are lined up in the width direction of the web, and to form a web 4 on a collection surface 3. A metering pump 5 is individually installed in each spinning head, and if a narrow nonwoven fabric is to be manufactured, some of the spinning holes in the spinning heads at both ends of the spinning head, which are closer to the edges of the nonwoven fabric in the direction of propagation, are installed. It is possible to make a nonwoven fabric of any width by blocking it and changing the discharge amount with a metering pump accordingly.
