The apparatus is used for wetting synthetic fiber tows with finishing liquid. For this purpose, the apparatus consists of two superimposed guide rolls over which the tow is guided in a meander-like manner. Padding devices are arranged on both sides of the tow between the guide rollers, the padding rollers of these devices act to transfer the finishing liquid from a bath located immediately thereunder continuously onto the two fed tangentially thereto.

A lightweight container for storing synthetic fibers, liquids granular materials and the like above the level of the floor has a bottom wall and a plurality of upright side walls joined together and attached to the bottom wall. Each of the side walls is formed of sheet metal and is provided with horizontally arranged profiled portions extending in parallel to the bottom wall. In addition, the side walls have identical profiled portions which are spaced from the bottom wall in a corresponding arrangement so that the profiled portions mate or match around the periphery of the container.

A heat treatment tunnel for the treatment of fibers, threads slit film or the like fibrillary material used in the textile field is arranged to extend horizontally. The material to be heat treated is transported along a travel path, in endless length form, through the horizontally arranged tunnel. This tunnel includes a heat-insulated housing having an inlet slot for entry of the material and an outlet slot for withdrawal of the material from the housing; a fan chamber; a fan arranged within the chamber for effecting circulation of a gaseous treatment medium within the housing; a heater disposed downstream of the fan for heating the treatment medium; a fan intake connecting pipe positioned either above or below the traveling material to draw the gaseous treatment medium away from the travel path and fan exhaust openings positioned either below or above the traveling material; i.e., opposite to the location of the fan intake connecting pipe, to direct the gaseous treatment medium toward the travel path. The heater extends in parallel with an in close juxtaposition to the travel path over the entire length and width of the travel path. A screen wall is arranged above and below the heater for regulating the flow of treatment medium whereby heat is retained around the heater to provide a source of uniform heat across the width and length of the traveling material. Also, a seal or closure is provided for sealing marginal zones of the heater so that the zones are gas-impermeable; i.e., no gas can pass into or out through the zones.

An apparatus consisting of a stuffer box crimping device of a conventional type with a cooling device immediately following thereafter and designed as a sieve drum under a suction draft. The dense crimped parcel, conducted to the sieve drum surface from the crimping chamber optionally by way of a chute is seized by the cooling air, thereupon cooled, and continuously transported. The thus set crimped structure can then be deposited without problems onto an endless belt arranged at a spacing therefrom.

The invention relates to an apparatus for cutting synthetic fiber yarns into staple fibers, for which purpose the yarn is wound several times around a knife cage and rests on blades oriented radially outwardly with their cutting edges and is urged from the outside radially inwardly against these blades by means of a contact roller. The blades are held in two blade-supporting disks arranged at a mutual spacing in superimposed relationship. In order to guide the cut staple fibers radially inwardly behind the blades, and for connecting the two blade-supporting disks with each other, approximately radially oriented partitions are provided directly adjoining several of the backs of the knives, these partitions extending at least in part over the height of the knife cage along the staple fiber discharge chamber in the center of the knife cage.

Apparatus for cutting ribbon- or cord-like material

A device for drying textile material has a closed housing accommodating a conveying means comprising a sieve drum that is under a suction draft and that is covered to prevent flowthrough of gases in the zone not contacted by the textile material; a fan associated with an end face of the sieve drum for withdrawing the gaseous treatment medium from the sieve drum and for blowing the gaseous treatment medium back into a space around the sieve drum; and an annular gap provided between a fan intake connection, or duct, and a wall provided with the drum spider for supporting the sieve drum. The gap is surrounded by an annular duct open toward the gap into which terminates burners of a direct flame heating unit for heating said gaseous treatment medium.

According to the disclosed process, an endless fibrous material to be cut is wound in spiral form onto a rotatable cutter roll having radially outwardly oriented knives. A cutting force acts from the outside of the cutter roll radially inwardly, by way of a pressure roller contacting the wound material, for cutting, for example, synthetic fibers. In the process, at least two cutting forces are effective against the axis of the cutter roll, these forces being directed against each other. In the apparatus for conducting the process, two pressure rollers are articulated to each other by way of a double rocket arm. Consequently, the optimum cutting level, which will be different in individual cases, is automatically set. The effective cutting force for each roller is of equal strength.

Process and apparatus for continuous cutting of strip- or rope-like

A cutting apparatus consists of two cutter cages arranged in direct superposition, with radially outwardly oriented cutters onto which a textile material to be cut is wound in spiral shape and is cut by a pressure roller effective from the outside radially inwardly. The two cutter cages are constituted by cutter supporting disks attached to a spoked wheel; these disks carry cutters which simultaneously equip the upper and lower cutter cages. By using such an apparatus, it is possible to cut simultaneously two continuous strands with only a single device. It is also possible to arrange more than only two cutter cages in superposition at one apparatus.

Process and apparatus for cutting band- or skein-shaped material

The length of material, provided uniformly over the operating width with a liquid mixed with frothing chemicals, is to be massaged on the pile side for producing the froth and/or for the complete wetting of all pile fibers. A reel or a similar device exhibiting round bars uniformly distributed over its circumference and partially encompassed by the material serves for this purpose. The length of material is in contact under tension with the rotating reel. On the rear side, the material is urged against the reel by means of an air-impermeable hugger belt, held under tension, or by means of a wearproof pressure shell.

Apparatus for froth processing of lengths of material

The steaming device consists of two halves, one of which is arranged above a fiber route and the other of which is arranged below the fiber route. The steam expands, from a steam supply nipple extending into a U-shaped housing, first into a distributor chamber covered by a partially permeable metal sheet. The metal sheet exhibits perforated zones arranged at mutual spacings, these zones being located with respect to the zones of a further perforated metal sheet, arranged thereabove at a spacing, in such a way that permeable regions of one metal sheet are disposed oppositely to impermeable regions of the other metal sheet. A heater is provided between the two perforated metal sheets. The halves of the steaming device are mounted so that they can be swung open and are regulated by means of a steam supply safety circuit.
