Abstract
A textile machine thread traversing device includes a traversing arm and a holding device to retain the arm as it moves in a back and forth motion. A drive mechanism is connected to the holding device to rotate the holding device relative to a turning axis. A programmable control system is configured with the drive mechanism and includes a detecting device disposed to detect the angular position of the traversing arm and to control the drive mechanism as a function of the angular position.
Claims18
A thread traversing device, comprising:
- a traversing arm, and a holding device to retain said arm as it moves in a back and forth motion between defined reversing points;
- a drive mechanism connected to said holding device to rotate said holding device relative to a turning axis;
- a programmable control system in operable communication with said drive mechanism, said control system including a detecting device disposed to detect the angular position of said traversing arm;
- and
- wherein said control system calculates the position of said reversing points at least in part by winding parameters input by a user and controls said drive mechanism as a function of the angular position of said traversing arm detected by said detecting device in relation to said calculated reversing points so that said traversing arm is pivoted back and forth between said calculated reversing points in a traversing zone, said calculated reversing points being non-physically defined by stop devices engaging against said traversing arm such that the location of said reversing points is variable by said control system without the necessity of changing or reconfiguring any such stop devices.
