PATENT OFFICE.

The essence of the present invention consists in the fabrics to be finished with a To undergo pre-treatment of its own kind and means specially built for this purpose To put devices in such a condition that the following work, which the Manufacture must be subjected to washing, pickling, dyeing, singeing, pressing, calendering and so on, no longer have any significant influence on the change in position of the fibers. It this is particularly important for products that, due to their manufacturing method, have a Easily allow the threads to be shifted, e.g. B. with all types of braiding and similar Wise produced substances.

The process is based on these products, as they are from the loom or knitting loom or from come to the braiding machine, in a raw, undyed condition, first in a stretched, taut condition through a tub to run, in which pure water or possibly a caustic liquid in kept boiling; from this vat the goods go over a drying cylinder, which is heated so high that the nature of the fiber allows it to suffer without damage. Here the position of the threads that come out of the cooking tub becomes soft and plastic are fixed, so that they no longer hold their position even with the subsequent manipulations change, and one obtains a beautiful, uniform looking commodity, especially with strands with level, straight edges and without any bad spots that would otherwise be caused by the settling arises.

But this pre-finish has a particular influence on the textile fiber, in that it prepares it for the subsequent dyeing in such a way that this work, the dyeing, can be carried out in a much shorter time than was previously necessary, as the pre-treatment _saves the fiber for absorption is made receptive to color. This is the main advantage of the new method.

For the practical implementation of the pre-finishing is the on the enclosed drawing The machine shown is constructed, which is particularly suitable for strand finishing, its main essence but can also be used for substances with possible minor changes.

Fig. Ι is a longitudinal section through the machine,

Fig. 2 shows a basic outline,

Fig. 3 is a front view, seen to the right of Fig. 1,

FIG. 4 shows a vertical section according to / - / of FIG. 1.

The goods A to be treated comes from any reel, pile, etc. and is guided over a tensioning frame B , from which it arrives in the cooking tub C. In this it is wound in multiple turns over rollers DD ^{1 arranged at the two longitudinal ends} guided, which lie in side strips so that they can be easily lifted out, or that the whole frame can also be lifted out; the goods are moved from top to bottom, over five to eight such rollers on both sides, depending on the height of the vat, ■ at an average speed of 10 m per minute. The goods rise from the lowest roller ΰ ¹ at the outlet end of the vat and

is passed above a guide roller E , from which it arrives at the drying drum F.

The drying drum consists of a correspondingly wide and wide copper cylinder with an internal heating device (steam heating), as used for the known cylinder machines. The same is stored in two stands G and equipped on one side with a toothed wheel H , which is in mesh with a gear J on the countershaft K, which is also stored in the stands G and receives drive from some transmission by means of pulleys L.

The goods are guided from the guide roller around the cylinder F using a guide roller M and a pressure guide roller N. The axis of the former is mounted in arms O on the uprights G , while the pressure guide roller rests in a weight-loaded lever P , the has its pivot point in the axis of M. Because the roller N is pressed onto the goods and the cylinder F , it is initially drawn tightly onto the cylinder surface and, as a result of the adhesion and the friction generated, is carried along.

The goods fall over the pressure roller N over a guide plate Q. attached to the stands G into a container or pile below, or they can also be reeled directly onto a reel.

In order to be able to stretch the goods more or less in the vat at will, a grate R is suspended in the middle of the vat, over whose bars the goods run. The grate hangs on a chain or cord that runs over a roller 5 and can be more or less loaded at the free end by counterweight T in order to achieve more or less tight tension of the goods by pulling up the grate, as indicated by dotted lines .

A steam heating coil U located on the bottom of the tub serves to heat the liquid in the tub, but instead of which steam could possibly flow in directly.

Claims (2)

Patent Claims: 1. A process for pre-finishing textile goods, which consists in the fact that the goods are slowly passed through a vat in a taut condition, in " which is boiling water, to which pickling agents may have been added, for the purpose of boiling the goods and softening of the fiber, whereupon the goods turn over in a tightly drawn condition a highly heated drying cylinder is passed, whereby the fixation of the position of the Fibers or threads of the goods are to be caused against each other. 2. To carry out the in claim i. characterized method a device consisting of a clamping frame (B) in front of a vat (CJ, in which there is boiling liquid and the. With guide rollers DD ¹ on both longitudinal end walls for the purpose of moving the goods back and forth, and with a grate JR in the middle and a heating device (U) , and from a drying cylinder (FJ connected to the vat, on which a pressure roller (NJ presses the goods) to achieve a smooth, tight tightening of the same around the drying roller and pulling it through the cooking vat. For this purpose ι sheet of drawings.
