Abstract
A rotatable element (10) is configured with a helical, endless thread guide passage (14) which is used to twist at least two threads (8, 9), particularly in a weaving machine's selvage forming device (7). The threads (8, 9) are guided in the passage (14) and displaced axially and mutually crossed by rotating the rotatable element.
Claims17
A method for twisting at least two moving threads comprising:
- running the threads substantially transversely and substantially tangentially relative to a rotatable element having at least one guide passage and guiding each thread in the at least one guide passage of the rotatable element;
- and
- causing the displacement to-and-fro of the threads in the axial direction of the rotatable element between two end positions and their mutual crossing between these end positions.
An apparatus to twist at least two threads, comprising:
- a rotatable element having a surface configured with at least one endless guide passage that runs helically in axial direction of said rotatable element between at least two axial end positions that includes at least one crossing location for the at least two threads, and that guides at least two threads extending substantially transversely and approximately tangentially relative to said rotatable element.
An Apparatus to twist at least two threads in combination with a weaving machine, comprising:
- a rotatable element having a surface configured with at least one endless guide passage that runs helically in axial direction of said rotatable element between at least two axial end positions that includes at least one crossing location for at least two threads, and that guides at least two threads extending substantially transversely and approximately tangentially relative to said rotatable element.
An apparatus to twist at least two threads in combination with a twisting machine, comprising:
- a rotatable element having a surface configured with at least one endless guide passage that runs helically in axial direction of said rotatable element between at least two axial end positions that includes at least one crossing location for the at least two threads, and that guides at least two threads extending substantially transversely and approximately tangentially relative to said rotatable element.
