System for tensioning a drive belt of a drafting system with a drafting system and a belt tensioner

Abstract

The invention relates to a tensioner for a spinning machine, having at least two pairs of rollers, which each have a top roller and a bottom roller, and at least one drive motor 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, wherein 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 invention further relates to belt tensioner jaws for adjusting the drive belt tension of a tensioner, and to a system for tensioning a drive belt of a tensioner, comprising a tensioner and a belt tensioner jaw. In order to provide a tensioner, a belt tensioner jaw and a system comprising a tensioner and a belt tensioner, which enable simple adjustment of the drive belt tension, it is provided for the tensioner that the at least one drive motor is mounted on the bottom roller carrier so as to be pivotable about an axis of rotation and fixable in a set position.
