respective deflection roll 3 for the textile material 2 at the region of such deflection rolls 3 which are effective as squeezing rolls for the textile material 2 which is guided thereover there are arranged the auxiliary lines or conduits 7a 7b 7c and 7d and specificially each auxiliary line flow communicates each two respective chambers or compartments which are situated above one another hence it will be seen that the line or conduit 7a flow communicates the chamber 11 and 13 the line 7b the chambers 12 and 14 the line 7c the chambers 15 and 17 and finally the line 7d the chambers 14 and 16 during operation of this equipment the textile material 2 which is pulled upwardly with a tensile load in the direction of the arrow 2a is automatically squeezed during its deflection about each of the deflection rolls 3 so that part of the treatment liquid is removed from the strand like textile material 2 the squeezed quantity of treatment liquid causes a damming up of the treatment liquid over the level of the corresponding outlet opening of the related auxiliary line 7a 7b 7c 7d as the case may be so the treatment liquid can flow through the auxiliary lines 7a 7b 7c 7d into the respective chambers or compartments 11 12 13 14.
