LAMBERT I-LAAS, OF VIENNA, AUSTRIA-HUNGARY, ASSIGNOR TO FRITZ GEBAUER, OF BERLIN, GERMANY.

CALENDER FOR DYEING, STARCI-IING, AND MERGERIZING MACHINES.

To all whom it may concern Be it known that I, LAMBERT Haas, a subject of the Emperor of Austria-Hungary, and resident of Vienna, Austria-Hungary, have invented new and useful Improvements in Calenders for Dyeing, Starching, and Meroerizing Machines, of which the following is a specification.

In the textile industry for the purpose of finishing, starching, dyeing, mercerizing and the like, the textile fabric is often treated by rollers. The arrangement of rollers shown herein obviates certain faults which are experienced in the use of roller arrangements hitherto in use. These faults and the removal thereof by the new roller arrangement are described hereinafter with reference to calenders, since the mentioned faults are found more or less in dyeing, starching and mercerizing machines.

The calenders used in the textile industry have a number of cylindrical rollers which are placed horizontal and parallel either one above the other or in a horizontal series. Also calenders with a pair of conical rollers are used, one of which, at least, is engraved. These calenders serve for finishing and brighting fabrics and paper, and if one of the rollers is engraved, they serve for stamping ornaments into said fabrics or paper. When the finishing or brighting process is to be carried so far that the cotton or linen fabric receives a silk-like brightness, these friction calenders have not been satisfactory and the so-called beetle stamping calenders had to be used. If the roller arrangement is used in a calender, with the same calender difierent effects may be produced for the production of which difierent machines have been necessary heretofore.

By the use of calenders with conical rollers placed complementarily to each other, it is possible to arrange a cylindrical roller between each pair of conical rollers, and the conical rollers may even be engraved.

An embodiment of my invention is shown in the accompanying drawing in which a pair of conical rollers in contact with a cylindrical roller is shown.

Figure 1 is a side elevation. Fig. 2 shows a vertical section on line A-B of Fig. 1.

With reference to the drawings, a designates the cylindrical roller, and b and a des- Specification of Letters Patent.

ignate the pair of parallel conical rollers having their small ends disposed in opposite directions. All these rollers are kept in position, as usual, by a suitable frame d. The cylindrical roller a is driven by means of a pulley e or in any other suitable way. But the drive may also be effected by driving one of the conical rollers. The fabric f to be treated is guided in contact with the rollers in the direction indicated by the arrow-head.

By the provision of the cylindrical roller a, between the complementarily arranged conical rollers b, c it is possible toproduce non-distorted goods, which was not possible heretofore with the well-known roller arrangements. By the new arrangement the fabric moves with the same side in contact with rollers of difierent diameters at diflerent places, and by the friction rising therefrom, the whole surface of the fabric is treated by equal frictional action, whereby on the whole surface an equal effect is produced.

IVith the new roller arrangement, now by a single set of calenders all those effects may be produced for which heretofore different machines have been necessary, such as rolling and friction water-calenders or beetle calenders.

In order to change the effects with the new roller arrangement, it is only necessary to modify the manner of working by the employment of rollers of a larger or smaller diameter, or by the use of one-sided pressure on the fabrics passing between said rollers.

The cylindrical roller a is made of steel, and is engraved or not, and the same may be provided with a heating device. The conical rollers are made substantially in the well-known manner, of paper, fabric, or the like. The amount of taper of the conical rollers is generally slight, the amount of taper depending somewhat upon the pressure to be used thereon.

Having now described the nature of my invent-ion, what I claim is:

1. In an arrangement of rollers of calenders, machines for dyeing, starching, mercerizing, and the like, the combination of a pair of parallel conical rollers having their smaller ends disposed in opposite directions, means provided with a cylindrical surface in contact with both of said rollers as and for the purpose specified, and means for for the purpose specified, and means for rocausing motion to be imparted to the rollers. t-at-ing one of the rollers. 10
