ィルム状に成形できるようにしたものである。DETAILED DESCRIPTION OF THE INVENTION (Technical Field of the Invention) The present invention relates to a film-forming device for a foamed defibrated material, in which a thin cylindrical foamed defibrated material sent out from an annular slit of a circular die is torn. This allows it to be formed into a film of uniform thickness without any problems.

仕上がってしまう問題点があった。(Conventional example) As a device for forming a thin cylindrical foamed defibrated material sent out from an annular slit of a circular die into a film shape, a disk-shaped guide member is installed above a circular die 61 as shown in FIG. 62 and take-up rolls 63 and 63 are disposed, and the foamed defibrated material 65 sent out in the form of a thin cylinder from the annular slit 64 of the circular die 61 is pulled while being guided along the disc-shaped guide member 62. Roll for scraping 6
It is known that the film is sandwiched and formed into a film by the rolls 63 and 63. However, in this case, the defibrating body 65 is connected to the disc-shaped guide member 62.
Since the defibrated body 65 is guided in an annular manner by the rollers 63.63 and pinched by the rolls 63.63 to form a film-like defibrated body 65°, the defibrated body 65 is guided in an annular manner by the rolls 63.6 for take-up.
The part with a large distance from directly below 3, that is, roll 6
The central portion 65a in the length direction of 3.63 is taken up by the roll 63.63 under a large tension, and the central portion 65a becomes thinner. There is a problem in that the tension on both sides 65b, 65b, which is relatively small in distance from each other, is finished thicker.

わめて破れやすい問題点があった。In order to solve this problem, the present applicant previously proposed a film-forming device for foam defibrated material equipped with a guide member that can be expanded and contracted (Japanese Patent Application No. 162,676/1982); If the viscosity of the defibrated foam or the coefficient of friction with the guide member is high, it will become sticky and easily get caught on the guide member.
In this case, the foamed defibrated material is extremely fragile, and therefore has the problem of being extremely easy to tear.

体を作業性よく成形できるようにしたものである。The guide member is formed of a rolling element, and the rolling element is rotatable in the direction in which the foamed defibrated body is fed. With this configuration, the foamed defibrated material sent out in the form of a thin cylinder from the circular die is guided while moving the guide member, and taken up while being pinched by the take-up rolls. This makes it possible to form a film-like defibrated body of uniform thickness with good workability while preventing the fragile foamed defibrated body from being caught in the guide member and torn.

In addition, since an appropriate tension is applied to both sides by the guide members 8.12.12, unnecessary wrinkles or overlaps do not occur on both sides of the defibrated body 7, and the defibrated body 7 is sent out in a cylindrical shape from the annular slit 6. The defibrated body 7 is taken up by the take-up roll 2 in its horizontal direction (A) and width direction (B).
Guide member 8.1 that coincides with the length direction (c) of 0.20
2.12, after guiding the deformation into an oval or elliptical shape, it is sandwiched between rolls 20 and 20 and formed into a film in stages, so that the defibrated body 7 is not unduly deformed. This prevents the stress from being generated and breaks the defibrating body 7, which is guided by the guide member 12. 4(c)) is extremely small, the defibrated body 7 is easily taken up by the take-up rolls 20, 20, and a film-like defibrated body 7° having a uniform thickness can be formed. Furthermore, when changing the width of the film-like defibrated body 7, the position of the guide member 12, 12 can be adjusted by moving the tube body 15 up and down along the threaded portion 16 to expand and contract the guide member 12,12.

滑に引き取り用ロール２０．２０へ送ることができる。(Effects of the Invention) As explained above, in the present invention, both sides of the inner surface of the foamed defibrated body 7 are guided by the guide members 12, 12 that move in the feeding direction. Even if the viscosity and friction coefficient of the material is high, it can be smoothly sent to the take-up roll 20.20 without tearing.

The maximum distance between the roll 20 and the contact surface of the roll 20, 20 that takes over the defibrated body 7 can be reduced, and thereby a film-like defibrated body 7° having a uniform thickness can be formed. Further, the defibrated body 7 sent out in a cylindrical shape from the annular slit 6 is deformed by the guide member 12.12 into an elongated cylindrical shape that is long in the length direction (c) of the take-up roll 20.20. Since it is formed into a film-like defibrated body 7' by being sandwiched between the rolls 20 and 20, the cylindrical defibrated body 7 is formed into a film-like shape in stages, without causing unreasonable deformation stress. , roll 20.20.
