Draft roll system for spinning machines |
摘要 |
The present invention provides a draft roll arrangement in a spinning frame in which the apron bottom roll is longitudinally divided into two sections at a location along its length selected to be within a range for which torsion of the apron bottom roll does not pose a problem in spinning, and in which the respective bottom rolls are operatively connected to one another in such a manner that one of the ends of the back and front bottom rolls and one apron bottom roll section are connected to a driving source and the drive for the other apron bottom roll section is derived through the back and front bottom rolls. In a preferred embodiment, the respective apron bottom roll sections are associated with rotational angle sensors whose output rotational angle signals are supplied to a control unit. When the difference in the rotational angle has exceeded a preset value, an output signal indicating such state is issued from the control unit.
