ABSTRACT:
A process for operation of an approximately horizontal suction duct used for removal of broken fragments of thread or roving from a spinning machine and a suction apparatus for performing that process. In the process of my invention the suction capacity of the suction duct is made adjustable for joint adjustment of the suction at all of the suction intakes connected to it. Thus to reduce energy consumption this suction capacity can be set to a considerably lower value during normal operation than during doffing or batch changing where it is desirable to use the maximum rated suction capacity. The adjusting means for changing the suction capacity of the suction duct comprises advantageously a throttling means such as an automatically controllable plate mounted downstream from the suction intakes of the suction duct or a selector switch for providing different voltages to the winding terminals of an electric motor of an air blower mechanism to directly change the suction capacity.
