Abstract

A wet processing jet machine for treating textile piece goods in rope form at a low liquid ratio. A plug supporting tube is provided as a vertical extension of a U-shaped processing chamber. The sides of the chamber are perforated and the bottom is imperforate for enhanced movement of the plug through the chamber. The tube extension is perforated to allow flow of liquid therefrom for enhanced plaiting. The amount of liquid with the rope in the plug is minimized for low liquid requirements and the head of the plug causes the plug to progress through the chamber above the low level of the liquid in the bottom of the vessel, which liquid level is below the bottom of the chamber or at least at a level that does not cause substantial floatation of the plug. The rope entering the tube is plaited by passing through an inverted frusto-conical plaiting nozzle that is oscillated and reciprocated to provide effective plaiting. In addition, a steam jet nozzle is provided for treatment and also to provide a driving impetus to the rope as it travels through the machine. The nozzle is formed with an annular housing having a wide steam accumulation chamber connected to a narrow supply passage leading upstream to a wide distribution chamber from which the steam flows downstream through a delivery passage to an annular orifice opening at a downstream inclination into the interior housing through which the rope travels.
