Title: Method and machine for winding conical sleeves from paper or paste-board strip
Filed: 1953-09-22
Abstract: 784,833. Paper &c. tubes. MAJER, C. Sept. 22, 1953 [Sept. 22, 1952], No. 26161/53. Class 99(2). In a method for winding multilayer conical sleeves of paper or paste-board on a twospindle winding machine, a double segment 4, 5, corresponding to two sleeves, severed from a web 1 fed at right angles to the longitudinal axes of the spindles 10, 11 is turned and advanced a predetermined distance substantially in the direction of the web feed so as to bring the line 6 on which the double segment is to be divided over a cutter 9 by which the segment is then divided, the individual segments 4<SP>111</SP>, 5<SP>111</SP>, thus produced being then fed to the respective spindles 10, 11. As shown, the web 1 is fed in a horizontal plane containing the common axis of the spindles, two shaping blades 2, 3 cutting off the double segment 4, 5. The latter is turned by a pivot 7 to the position 4<SP>1</SP>, 51 so that the line 6 comes to lie substantially transversely of the direction of travel of the web and then drawn forward by a gripper 8 in the horizontal plane to the position 4<SP>11</SP>, 5<SP>11</SP> where the double segment is divided by the cutter 9, the individual segments then being laterally displaced in longitudinal slots provided in the spindles and bearings 26, 27 thereof. The spindles are supported at one end only and are driven as indicated at 28. Instead of displacing laterally the individual segments from the point 9 of division, the segments 411, 511 may respectively be moved backwardly and forwardly in the horizontal plane and then fed towards the spindles at a radial distance therefrom. The line 6 is always at the same distance from the centre of the pivot 7 so that different widths of web, or sleeves of different lengths may be dealt with.

The pressure in a tube 64 and the passages 14, 16, 52 and in the tube 60 is then increased by operating the pump 70 so that when the pressure in 64 is equal to or greater than the pore or earth pressure on the other side of the diaphragm the diaphragm is displaced to push the ball 24 back on to its seat 20. A reading is then taken of the closed off gauge 66 to give the pore pressure at that time.

[Class 41.] Copper is deposited on a cathode covered with a film of liquid, such as an unsaturated hydrocarbon, of such dielectric strength and wetting power that the current pierces it at relatively distant points to start building copper crystals which are wet by the film as they are formed; the resulting deposit adheres to the cathode during deposition but is readily detachable and is sufficiently brittle to allow it to be granulated after removal. Suitable covering liquids are asphalt, linseed oil, sulphonated corn oil, and crude fuel oil. Glue is preferably absent from the electrolyte but goulac may be present.
