Zusammenfassung: | To provide a draft mechanism, a belt tension-adjusting plyer, and a system consisting of a draft mechanism and a belt tension-adjusting plyer capable of simplified adjustment of the tension of the drive belt.SOLUTION: The invention relates to a draft mechanism having at least two pairs of rollers, which each have a top roller and a bottom roller 2a and 2b, and at least one drive motor 16a for driving at least one of the bottom rollers, wherein: the at least one drive motor and the bottom roller, which can be driven by the at least one drive motor, are arranged on a bottom roller carrier 1; and the at least one drive motor, which is connected to the bottom roller via a drive belt, is arranged on the bottom roller carrier such that its distance from the bottom roller can be varied in order to set a drive belt tension. The drive motor is supported by the bottom roller carrier, which can be rotated around rotary shafts 7a and 7b and fixed in an adjusted position.SELECTED DRAWING: Figure 2
【課題】ドラフト機構、ベルト張力調節プライヤ、並びに駆動ベルトテンションの簡易な調整を可能にするドラフト機構とベルト張力調節プライヤからなるシステムを提供する。【解決手段】上部ローラ及び下部ローラ2a,2bを有する少なくとも2つのローラ対と、下部ローラのうちの少なくとも1つを駆動するための少なくとも1つの駆動モータ16aとを有し、少なくとも1つの駆動モータと、少なくとも1つの駆動モータにより駆動可能な下部ローラとは下部ローラ支持体1に支承されて配置され、駆動ベルトを介して下部ローラと結合された少なくとも1つの駆動モータは駆動ベルトテンションを調整するために下部ローラに対して間隔変更可能なように下部ローラ支持体に配置され、駆動モータは回動軸7a、7bを中心として旋回可能に、かつ調整された位置で固定可能に、下部ローラ支持体で支承されるドラフト機構。【選択図】図2 |
