Abstract
A device for moving a thread to a winding sleeve driven by a friction wheel, especially in a stretch-winding machine, has a tubular portion adjacent the mouth into which the thread is drawn by suction and which is provided with at least one blade to sever the thread with a minimum tension applied thereto. That keep the loose ends as short as possible.
Claims11
A device for moving a thread to a winding sleeve driven by a friction roller, said device comprising:
- a suction element connected to a suction source;
- a terminal tubular member connected to said element and having a mouth at which a thread is drawn into said member;
- and
- two separate blades spaced apart in a direction of travel of the thread and each formed with a respective cutting edge in said terminal tubular member for severing a thread drawn into said device, said blades being oriented diametrically opposite to one another.
A device for moving a thread to a winding sleeve driven by a friction roller, said device comprising:
- a suction element connected to a suction source;
- a terminal tubular member connected to said element and having a mouth at which a thread is drawn into said member;
- and
- two separate blades spaced apart in a direction of travel of the thread and each formed with a respective cutting edge in said terminal tubular member for severing a thread drawn into said device, said blades being inclined inwardly in a direction in which said thread is drawn into said device, said blades extending inwardly beyond a centerline of said member from locations above and below said centerline, respectively.
A device for moving a thread to a winding sleeve driven by a friction roller, said device comprising:
- a suction element connected to a suction source;
- a terminal tubular member connected to said element and having a mouth at which a thread is drawn into said member;
- and
- means forming at least one cutting edge in said terminal tubular member for severing a thread drawn into said device, said mouth having a smaller diameter than said member inwardly of said mouth.
