Device for treating strand-shaped textile fabric in the form of an endless fabric strand

A device for treatment of a strand-like textile fabric in the form of an endless fabric strand, the device comprising:

• a lockable treatment container;
• a transport nozzle arrangement which can be subjected to a first transport medium flow;
• and
• a transport section adjoining the transport nozzle arrangement, the transport section terminating on a fabric strand inlet side in a storage section of the lockable treatment container, the storage section accommodating a folded fabric strand pile, wherein:
• the transport nozzle arrangement comprises a transport nozzle with:
• a polygonal nozzle inlet opening delimited in straight lines;
• and
• an outlet part comprising a polygonal cross-section for the fabric strand, the outlet part having an outlet opening and being appropriately adapted in view of its dimensions, these delimiting between them a single nozzle gap for the transport medium;
• the nozzle gap is adjustable;
• and
• at least one side of the nozzle gap is delimited all the way around by a plurality of straight nozzle elements, each of the straight nozzle elements having a cross-sectional shape that is essentially part-cylindrical, and the straight nozzle elements being connected to each other at ends thereof to delimit the nozzle inlet opening in the straight lines on all sides by essentially part-cylindrical surfaces.
