Description

【００１２】
ところで、ばね手段は、カム部材によって偏心軸の半径方向に変位される、カム従節としての加圧ピースと、この加圧ピースを偏心軸の中心方向に付勢するばね部材とで構成することができ、この場合は、引張りタイプもしくは圧縮タイプとすることができるばね部材のばね力を、加圧ピースを介してカム部材に作用させることで、ニップロールの、上述したような作用をもたらすことができる。[0012]
By the way, the spring means comprises a pressure piece as a cam follower which is displaced in the radial direction of the eccentric shaft by the cam member, and a spring member which biases the pressure piece in the central direction of the eccentric shaft. In this case, the spring force of a spring member, which can be of a tension type or a compression type, acts on the cam member through the pressure piece to bring about the above-described action of the nip roll. it can.

そしてまた、この発明に係る作業装置は、上述したニップ装置のいずれかを、一の共通の支持ロールの周りに、それの円周方向に間隔をおいて、ニップロール軸線を支持ロール軸線とほぼ平行にして複数配設したものである。
ここでより好ましくは、ニップ装置間に、支持ロールと協働して作業を行う一もしくは複数の作業ロールを配設する。[0019]
Also, according to the working device of the present invention, the nip roll axis is substantially parallel to the support roll axis, with any of the above-described nip devices being circumferentially spaced around one common support roll. And multiple arrangements.
Here, more preferably, one or more work rolls that work in cooperation with the support roll are disposed between the nip devices.

この一方で、偏心軸１２、ひいては、ニップロール８の、後方側支持フレーム１３の方向への相対変位は、偏心軸上に、ボス１７に対してカラーとは反対側でそのボスに接触するカム部材２０を固定することにより阻止することができる。[0029]
On the other hand, the relative displacement of the eccentric shaft 12 and hence the nip roll 8 in the direction of the rear side support frame 13 is a cam member which contacts the boss 17 on the opposite side of the boss 17 on the eccentric shaft. It can be blocked by fixing 20.

Claims
