Abstract
Systems for controlling the movement of threads in systems for treating threads for carpets. Disclosed is a device for guiding a strand of at least two threads on a transporter structure, characterized in that the device employs a mechanism for generating false twists between the at least two threads of the strand.
Claims13
A system for treating threads for carpets comprising:
- a guiding device configured to guide at least two threads of a strand onto a transporter structure, wherein the guiding device comprises a false twisting device configured to generate false twists between the at least two threads of the strand, and wherein the guiding device is positioned upstream of a mechanism for depositing the strand in loops on the transporter structure,
- wherein the transporter structure is configured to move the loops in a longitudinal direction, and
- wherein on the guiding device, a tension of the at least two threads of the strand at the false twisting device is lower than the tension of the at least two threads of the strand upstream of the false twisting device.
A method of guiding at least two threads of a strand onto a transporter structure, the method comprising:
- generating at least one false twist of the strand between at least two threads of the strand, wherein a tension of the strand when the at least one false twist is generated is lower than the tension of the strand before the false twist is generated;
- depositing the strand in loops on the transporter structure;
- and
- moving the loops in a longitudinal direction via the transporter structure.
