"Method and device for handling railway goods"

The invention relates to a method and a device sub Treat like thermosetting, thermosetting, condensing and similar treatment, of railway goods, especially textile goods that tend to shrink with this treatment / in several Stages, for example a Aufheia, a fixation and a KUhlatufe, the device for performing this method consists from a closed housing, which is divided into chambers by transverse walls is subdivided, preferably each chamber by «in · wall in a ventilator and a treatment room is divided. In the treatment room of each chamber there is at least one under suction Screen drum provided as a transport element.

For example, in thermosetting and thermosetting is one Step treatment known. The textile webs are thereby on a Multi-span clamping frame treated. In some fields it is pre-dried and lightened, then the other fields are fixed and in a final Spannrahaanfeld cooled. With this tenter frame construction the goods are held on both sides by clips or needled onto needle chains during the entire treatment. I am more essential Disadvantage of our known device is that the clamping frame are very expensive due to the tension chains that can be adjusted to different treatment widths. The tension chains are also very prone to failure, so that there are frequent and longer downtimes ko'Jirat.

The invention is based on the object of providing a device create the shortest possible treatment pages, for example using the ventilation principle is possible and at the same time free, uncontrolled shrinkage of the web material is avoided.

The invention is based on the knowledge that in many treatment processes the shrinkage of the material occurs essentially with a certain treatment process or under certain treatment conditions, while during the remaining treatment time a shrinkage of the material remains within negligibly small limits. The invention is based on this knowledge and solves the set problem in a simple manner in that the web-like material is clamped or held on both sides in only one stage, and only in the upper stage in which the material essentially collapses. In the other treatment stages, the web material is only guided and held on the screen drums by the suction of the screen drums.

It has been shown that in many treatments! Shrinkage of the material, in particular textiles consisting of synthetic fibers or textiles containing synthetic fibers, starts at a certain treatment temperature. This means the shrinking of the material essentially to one treatment level To limit, it is proposed in an embodiment of the invention, the treatment temperature different levels in the individual stages to keep and only in the treatment stage, in which the material is on both sides is performed, temperatures should be provided 'at which a strong shrinkage of the material takes place. In the heating stage the material should preferably be 10-30 C below the temperature remain, in which a noticeable shrinkage of the Materlales takes place

If the holding and fastening elements are only to be seen on one troma, then these elements can be designed in a ring shape or can be designed simply on the outside.

In an embodiment of the invention, it is proposed that this device aa inlet a broad-headed device | pre-switch. One of the spreading devices known from calibration can be used for this.

Among other things, a good transfer of the web-like goods to the old holding and fastening elements provided screen drum is proposed according to another inventive idea, this screen drum a device for needling and / or specifying the web-like goods in length and / or width to switch. Only by specifying the width of the material on the sieve drum, which is provided with fastenings and holding elements, is free shrinking possible in accordance with the specification of the material. Due to the holding and fastening elements, however, the material can only shrink up to a certain width, since it is then held in this width and further shrinkage is prevented. Ulerdurc ensures that the web material leaves the treatment device after an exactly predetermined treatment width.

This chamber of fixers; In which the material is held taut, a cooling chamber is connected downstream. It is particularly important that the material is cooled as quickly as possible in order to obtain a free. To prevent shrinkage and to "freeze ¹ * of Faserflxlerung KU allow Generally his drum can not be avoided during the handover of the fixing on the KUhItrommel some necking when this also remains within narrow limits.

The holding and fastening elements on the sieve drum can beitpielswtiee consist of rings fitted with needles or from ringsegents. These rings or ring segments can be attached to spindles stored and thus produced automatically from the outside or can be adjusted to the desired treatment width.

Since the different materials shrink differently and a shrinking in an elongated manner must generally be made possible, it is advantageous to provide the conveying speed for the individual screening drums so that they can be continuously changed. It is also advantageous if the conveying speed is different in the individual chambers. This ensures that, for example, at a higher conveying speed & τ heating chamber, the material in the fixing chamber can be needled onto the fixing drum with a specified length. As a further request for the Fördergesohwindlg-. cold between the fixing chamber and the cooling chamber, an additional opening can also be made possible. In various Faller However ea is also conceivable, or the conveying speed of the screen drum, dBT screening drums of the cooling chamber a little larger than's ^conveyor: is achieved schwiadigkeit to choose the Fixierkammor thereby stretching the Materialee and thus a BUgeleffekt.

In order to use the device according to the invention as many application guidelines as possible to give, it is proposed according to another idea of the invention, to make the device usable for various treatment media. For example, the material for a Passing through the device are dried and fixed in a pass, for example under steam.

In an embodiment of this inventive concept, it is proposed that to separate individual chambers so well, baw. to seal so well from one another (laIi in the individual chambers different Treatment media can be used. E.g. the material of the aryten chamber heated by hot air and in a subsequent Kammex be fixed in a steam atmosphere. The cooling of the material »· kmno. then take place again under cold air.
