本発明は、押出ラミネート等のＴダイに用いられるデッ
ケルに関する。DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a deckle used in a T-die such as extrusion laminate.
（従来の技術）
従来、Ｔダイ法によりラミネートフィルムを製造する際
には、原料樹脂の種類の違い、成形条件の違いにより、
押し出されてくる樹脂の粘度、樹脂の流速か異なってく
るため、フィルムの偏肉や、フィルムの両端縁の種々の
トラブル（例えば、樹脂切替時の清掃不良による両端部
の接着不良等のトラブル）か発生する問題点かあった。(Conventional technology) Conventionally, when manufacturing laminate films using the T-die method, due to differences in the type of raw material resin and differences in molding conditions,
Because the viscosity of the extruded resin and the flow rate of the resin differ, uneven thickness of the film and various problems at both edges of the film (for example, problems such as poor adhesion at both ends due to poor cleaning when changing resin) There were some problems that occurred.
このような問題点を解決するため、従来、それぞれの条

わせた形で分割可能に設けていた（２段型デッケル）。Conventionally, such problems have been solved by changing the deckle with a shape appropriate for each condition to regulate the flow width of the resin. Fig. 3 is an overall view showing a conventional general T-die device, in which 11 is the T-die body, and deckles 12 (integrated deckles) are provided on both sides of the T-die body to regulate the flow width of the resin. The deckle had to be replaced due to differences in molding conditions. In addition, as an improved technology that makes it easier to replace the deckle, for example,
There was one described in Japanese Utility Model Publication No. 5879323. FIG. 4 shows the deckle for T-die of the publication,
Reference numeral 11 denotes a T-die main body, and deckles 12 are provided on both sides of the T-die body so that they can be divided into two layers, an upper deckle 12a and a lower deckle 12b (two-stage deckle).
各々のデッケル１２ａ 、１２ｂはそれぞれ別々の支持
棒によって支持されている。そして、樹脂の違い、成形
条件の違いにより下部デッケル＋２ｂのみを支持棒と共
に引き抜いて別の下部デッケル１２ｂと交換してしてい
た。Each deckle 12a, 12b is supported by a separate support rod. Then, due to differences in resin and molding conditions, only the lower deckle +2b was pulled out together with the support rod and replaced with another lower deckle 12b.

A T-die deckle, in which one end of a flexible metal plate spring is fixed to the resin passage surface of the die deckle, the other end of the metal plate spring is fixed to an adjustment rod, and the adjustment rod is made slidable. It's an old thing. In addition, the T-die deckle is divided into upper and lower parts, and one end of a flexible metal plate spring is fixed to the resin passage surface of the lower deckle, and the other end is fixed to an adjustment rod, which can be slid. This is a deckle for T-die.
