Abstract
A thread displacement device for displacing a thread on a winding body includes a thread guide, which, depending on a movement of the winding body, can be freely selectively moved back and forth along a curved path defined by guide means. The thread guide has a thread guide roller rotatably mounted about a thread guide roller rotational axis to guide and press the thread against the winding body, said thread guide roller being configured as a self-directing roller. The guide means includes a flexibly deformable traction means, which can be guided back and forth via deflection rollers and/or deflection rods and on which the thread guide is directly fastened.
Claims14
A thread displacement device for displacing a thread on a winding body, the thread displacement device comprising:
- a thread guide comprising a thread guide roller rotatably coupled about a thread guide roller rotational axis to a thread guide head, the thread guide roller configured as a self-directing roller to guide and press the thread against the winding body, and where the thread guide head is pivotably coupled about a rotational axis to a holding part of the thread guide, where the thread guide roller rotational axis of the thread guide roller is substantially perpendicular to and spaced apart from the rotational axis of the thread guide head, and where the thread guide head is displaceable in translation along the rotational axis in relation to the holding part of the thread guide;
- and
- a guide means comprising a flexibly deformable traction means, the traction means defining a curved path, the curved path disposed along a respective spatial plane, where the thread guide is directly coupled to the traction means along the curved path and where the thread guide, which, depending on a movement of the winding body, can be freely selectively moved back and forth along the curved path defined by the flexibly deformable traction means by means of deflection rollers and/or deflection rods, the thread guide being able to move back and forth on the respective spatial plane along the curved path between 7° and 348° relative to a starting orientation of the thread guide.
A thread displacement device for displacing a thread on a tire during tire manufacturing, the thread displacement device comprising:
- a thread guide comprising a thread guide roller, a thread guide head and a holding part of the thread guide head where the thread guide roller is configured as a self-directing roller to guide and press the thread against the tire, and where the thread guide roller is rotatably coupled about a thread guide roller rotational axis to the thread guide head, and where the thread guide head is pivotably coupled about a rotational axis to the holding part of the thread guide, where the thread guide roller rotational axis of the thread guide roller is substantially perpendicular to and spaced apart from the rotational axis of the thread guide head, and where the thread guide head is displaceable in translation along the rotational axis in relation to the holding part of the thread guide;
- a traction means defining a curved path disposed along a respective spatial plane, the thread guide moveably and directly coupled to the traction means where the thread guide is controlled by deflection rollers and/or deflection rods allowing the thread guide to move back and forth about the respective spatial plane along the curved path between 7° and 348° relative to a starting orientation of the thread guide;
- and
- a winding body rotatable about a winding body rotational axis, the tire attachable to the winding body;
- wherein the curved path's respective spatial plane is substantially parallel to the rotational axis of the thread guide head;
- wherein the winding body's rotational axis is substantially perpendicular to the rotational axis of the thread guide head;
- and
- wherein the curved path's respective spatial plane is substantially parallel to the winding body's rotational axis.
