    Abstract: PURPOSE: To optimize the plasma treating condition and the vacuum condition in a metal vapor-depositing process by covering a discharge electrode with a counter electrode having a slit opening and directing the opening toward a material to be treated. CONSTITUTION: A cathode 11 contg. a permanent magnet 12 generates a plasma discharge. The cathode 11 is covered with an anode 13 having a slit opening 14. The opening 14 is opened toward a plastic film 6 to be treated. The anode 13 is set in a vacuum deposition device, and a discharge gas is injected into the anode 13 from an inert gas cylinder 19. A plasma discharge 22 is generated between the cathode 11 and anode 13 to produce an ionized gas 23. The ionized gas 23 is blown off from the opening 14 to treat the surface of the film 6. A metal is vapor-deposited on the film 6. The gas pressure around the cathode 11 is increased by the sealing effect of the cathode 13. The metal vapor- deposition part is kept at a high vacuum independently of the plasma part.

    Abstract: PURPOSE:To provide the title apparatus whereby the gap between the discharge electrode and the opposite electrode roll can be kept always constant along the longer direction of the electrode roll. CONSTITUTION:The apparatus consists of a frame, an electrode roll 12, a discharge electrode 13, a supporting stay for the discharge electrode, heating means 16a to 16d provided on the upper and lower surfaces of the stay, means 15a and 15b for detecting the magnitude of deflection of the stay and a means 18 for controlling the magnitude of deflection of the stay. When a downward deflection develops at the stay, the heating means 15a on the upper surface of the stay is energized by means of the means 18, while the electric heater 15b on the lower surface is not energized to develop a deflection in the direction opposite to that of the above deflection. Thus, the deflection at the stay can be counterbalanced, and therefore the supporting stay and the discharge electrode are kept level, which keeps the gap constant during the discharge treatment.

    Abstract: PURPOSE:To provide a substantial, cleaning device for a sheet conveying roll, which, although it is small device with a short adhesive roll, is able to clean a long, sheet conveying roll, which can easily be attached/detached, and in which the adhesion of the adhesive roll can easily be set at a desired value. CONSTITUTION:An adhesive roll 5, which is covered with materials having stickiness, is brought in contact with peripheral surfaces of sheet conveying rolls 1, 2 and is rolled on the peripheral surfaces. As a result, substances sticking to the peripheral surfaces of the sheet conveying rolls 1, 2 can be removed. In addition, this cleaning device for the sheet conveying roll is provided with a moving means by which the adhesive roll 5 can be moved in the longitudinal direction of the sheet conveying rolls 1, 2.

    Abstract: PURPOSE:To obtain a high-quality roll product without wrinkles by disposing a bar provided with a pressure reducing chamber and a sucking port, and adsorbing a film to the bar so that the film can be cut in a tense manner without slackening and sticked to a new take-up core. CONSTITUTION:A take-up portion 1 in a film slitter is adapted to roll a film 2 cut to a fixed width round take-up cores 8 mounted on left and right take-up arms 7, and when the core 8 is rolled up, the film 2 is taken up on another roll by operation of a through bar 11. In this case, the through bar 11 has both ends supported on a switch arm 13, and is rotated by a motor. The through bar 11 has two suction paths 18, 19 as pressure reducing chambers axially extended in a space between pipes 16, 17 double-circular in section, and a plurality of suction ports 20, 21 are disposed axially in such a manner as to communicate with the respective suction paths 18, 19. Further, there is provided a groove 22 axially extended between the suction ports 20, 21, so that a cutting edge 23 moved by air pressure can be projected.
