Innovations in machines for opening, spreading and stretching fabrics for use

for bleachers, dyers, calico printers.

Patented in the German Empire on June 12, 1878.

The invention consists in an improved construction of the regulator on the machines, for which the English patents no. 2610, dated October 1, 1870, and No. 84, dated of January 8, 1877, granted by which improved construction the regulator either independently of any other Mechanism for opening, spreading and guiding tissues can be used, or also as before in combination with other mechanisms.

As before, the inventor uses a balanced frame around one in the center line the machine lying pin is rotatable.

However, instead of making the frame or balancer entirely from solid rods, one, several, or all rods can be rotated around their axis of length.

These rods or rollers can be smooth or canned, or seriate, cylindrical or conical, or in any other appropriate form. They are also under each other-parallel; the mutual position, as well however, the relative size, number and arrangement of the rods or rollers can be changed as desired will.

As long as the work piece is in the middle of the machine, i.e. the frame is in its equilibrium position remains, the rotation of the rollers has only a uniform smoothing or opening of the Fabric result, depending on whether the rollers are smooth or helically corrugated.

If, however, the frame is brought into an inclined position as a result of a deviation of the workpiece from the center line, then forms the incoming fabric on the side from which it departed, with the ends of the rolls an acute or more acute angle, and the different points of contact of the rollers now pull the tissue in the opposite direction during their rotation until the normal angle is restored, so until the direction of the tissue is back in the Direction of movement of the rollers falls.

If z. B. the workpiece has deviated to the right and the right end of the Has pulled the regulator forward, the rods are positioned to move the stuff to the left and thus lead it back to the center; then the balancer is also in his normal position Returned position and has no further lateral moving influence on the tissue.

This management of the work piece can now either be done entirely in the regulator itself or the regulator can, in addition to its direct action, also determine the position of the Work surfaces (screws, chains or belts, or smooth roller surfaces) control which one Purpose he, like the former regulator of the inventor, with the mentioned areas through Leverwork must be connected.

If you want to use the regulator or equipment manager to stretch the equipment, bend if you put each rod in the middle, so that the same instead of a straight line the two sides of one Forms an angle, the legs of which converge in the direction of movement of the equipment and unite at a point on the center line of the machine. These bars make up the Axes for rotating sleeves. Since in this regulator or straightener the movement direction roller points in contact with the witness with the direction of movement of the witness always forms an angle, the rollers pull the stuff outwards from the center and thus opened, stretched or smoothed. The effect of this arrangement can be further strengthened by the fact that one of the rollers is made of two parts, their each end can be rotated like a door hinge and is raised or lowered by means of a short lever arm attached to the end and thus more or less can be brought into contact with the work piece. It this is effected by a gear manager by means of a lever connection.

The drawings show some forms of the regulator by itself and its connection with three different machine parts, namely screw cylinders, endless chains and stretching rollers.

Pin P is rotatable and is in its equilibrium position in FIG. 3, whereas it assumes the position in FIG. 4 as soon as the workpiece has deviated to the right. Fig. 5 shows a regulator with two fixed rods B1 B2 and one rotatable H1; 7 shows one with a fixed rod B3 and four rotatable H2. Fig. 6 shows a regulator, the rods of which converge from both ends towards the center forwards, and the outer rods of which carry rotatable sleeves. Fig. 8 shows the regulator in connection with two screw cylinders C and C. The bearings of the two cylinders are either fixed (as assumed in the figure), or one of the cylinders is mounted in a swing frame, which is connected to the regulator by means of a lever mechanism ZZ1Z2 as in patent specification no. 654, 1877. The arrangement of the regulator can be further modified. It can consist of any number of rods, either all of which are movable or some of which are fixed. The rods, whether rotating or fixed, can either all be parallel, straight or curved, or partly straight and partly curved. The rods, both mobile and fixed, can also be either cylindrical or conical, with a smooth, toothed, or canned surface. The solid bars are of course of any cross-section. 9 and 10 show elevation and side view, FIG. 11 a partial green elevation on a larger scale, of a machine with endless chains for stretching and smoothing, in which the new regulator G is used to lift the chains in and out by means of the lever L Z1Z2 . FIG. 12 shows a device in which the regulator is used twice, once as a conductor G and once as a stretcher S; both work here independently of each other. In Figures 13, 14 and 15, an arrangement is demonstrated in which the regulator is used in a manner similar to that indicated last; however here the conductor G1 is connected to the extensor S1 by the levers Z Z1 Z2 and the action of the extensor is regulated by the conductor. In the modification of the stretcher mentioned here, the middle rod is made of two parts, each of which is rotatable at the outer end about a pin and carries the short lever Z, by which one roller arm is raised and the other lowered, and thus on the one On the one hand, a stronger and on the other a less pressure is exerted on the work piece, whereby the influence of the arms becomes more or less intense. The relative size of the stretching rollers, as well as their inclination, number and arrangement, however, are not tied to the examples shown in the drawings, but can be changed as desired. Likewise, the rollers can be stored and fastened in different ways and the connection of the regulator with the movable rollers can be established by another suitable lever mechanism. Under certain circumstances, the inventor also lets the fabric go through the regulator before it gets between the screw surfaces, endless chains or stretching rollers. Pat ent-An s ρ odor: 1. The use of a balanced frame with one or more rotating rollers, with or without one or more solid rods for the purpose of guiding tissues. 2. The use of the same combination for the purpose of opening, smoothing and stretching of tissues, the rods either straight or angular, or partially straight and partly angular, also made with or without movable arms can be. 3. The combination of the equipment manager with the drafting system. 4. The use of the stuff manager as a regulator to help with suitable mechanisms to act on chains, screw rollers or similar devices. For this purpose 3 sheets of drawings.
