Pumping drainage equipment

The invention relates to an extraction device for guiding thread groups, in particular at the beginning of a melt spinning process. The suction device has a protruding suction tube which has a suction opening at a free end for receiving the thread group. The suction pipe is connected through an opposite end to an ejector device for generating a suction air flow. The suction tube is assigned a freely rotatable godet roller, which is held in position near the suction opening by means of a carrier. According to the invention, in order to obtain a substantially constant thread group pull-in angle independently of the thread feed, the godet roller with the carrier is pivotally held in front of the suction opening of the suction tube by means of a pivot bearing. 本发明涉及一种抽排设备，用于引导丝线组，尤其在熔纺过程的过程开始时。抽排设备具有突伸的吸气管，其在自由端具有用于接纳丝线组的抽吸口。吸气管通过相对一端被连接至用于产生抽吸气流的喷射器装置。吸气管被分配可自由转动的导丝辊，其通过托架距抽吸口近地保持就位。为了与丝线喂给无关地获得基本恒定的丝线组拉入角度，带有托架的导丝辊根据本发明通过枢转支承件可枢转地保持在吸气管的抽吸口前方。
