Abstract: In the textile industry there is a constant need for processes where the textile material to be treated can be treated in a simple form, for example in rope form instead of in the open-width state, and continuously. According to the invention, this need is met when the textile material is introduced via pressure seal elements into a specially constructed jet dyeing machine, is impregnated there with treating liquor during entry or immediately thereafter and is conveyed further in the machine by means of at least one jet operated by means of a gas stream, the treating agent applied, preferably dye, having advantageously been subjected to fixation in the course of the presence in the gas atmosphere. The necessary physical conditions (pressure, temperature) for this are created by the driving gas. Moreover, in the course of the passage of the textile material it is possible to carry out a further, including a completely different, impregnation.

Abstract: A seamless parison extruded from an extruder via an annular die, passes through a calibrator and coaxially surrounds a probe pipe, which is made to extend through the annular die beyond the calibrator. On the probe pipe there is mounted a sealing element. Ahead of the sealing element, a pressure equal to atmospheric pressure prevails inside the tube and, after the sealing element, a higher pressure than atmospheric pressure prevails. The pressurization is achieved in that a second belt take-off folds together the tube, so that the compressed air fed in through the probe pipe causes a higher tube internal pressure, since the sealing element bears in a sealing manner against the inside of the tube. As a result, a substantial pressure separation is effected at the point of the sealing element.

Abstract: An end wall comprises a plate having a smooth, plane fromt surface whereas its rear side is stiffened by radial ribs and annular ribs. A central insertion pin is provided on the front side of the plate. Each of the four side walls of the plate is equipped with stacking bosses limiting stacking pockets which are of complementary design to the stacking bosses. When vertically aligned end walls are being stacked side-by-side or one above the other, the stacking bosses and the stacking pockets of one side wall can be joined to the complementary stacking bosses and stacking pockets of a side wall of another end wall without a joint. Corner surfaces of the end wall are rounded off and provided with cylindrical locking bosses which have the same radius as the rounded corner surfaces.

Abstract: Process for dyeing textile wovens or knits made of polyester fibers or mixtures thereof with other fibers in jet dyeing machines.The recently developed jet dyeing machines with aerodynamic fabric transport permit a drastic shortening of the liquor ratio and of the addition of higly concentrated dye solutions or dispersions directly into the driving gas circulation system under isothermal conditions. However, the prerequisite is dyes in finished form.According to the invention, it has now been found that the costly finishing treatment is dispensible when non-finished disperse dyes are dissolved highly concentratedly in suitable, preferably water-miscible, ecologically and toxicologically safe organic solvents, and these solutions are metered with the aid of the new technology specifically into the circulating gas stream to form a dispersion of the dyes which then produces a level dyeing on the textile material.
