  • Patent number: 9222002
    Abstract: The present invention relates to a method for producing an adhesive tape (2). The adhesive tape (2) possesses a tapelike carrier (3) and at least one strip (4; 4a, 4b) of adhesive which is applied to the carrier (3) on at least one side. Here, first of all, a carrier web (1), coming from a supply unit (7), is supplied to at least one coating unit (9, 10). The coating unit (9, 10) then generates the at least one strip (4; 4a, 4b) of adhesive on the carrier web (1) in its longitudinal extent, by carrying out coating with an adhesive. Lastly, the carrier web (1) is slit in the longitudinal direction into the individual adhesive tapes (2); the two last-mentioned method steps may also be run in the opposite order.

  • Patent number: 4592403
    Abstract: An emergency operation ring for tubeless pneumatic tires on motor vehicles made of an elastomeric material and mounted on a rim by means of axial clamping pressure. Two support sections extend diagonally upwards and outwards from the base section and define a circumferential channel. The support sections have step shaped outer flanks set back with respect to the base section. At least one circumferential groove is provided contiguous the circumferential channel, and slipping agent is positioned in the groove or grooves. Sealing lips close off the groove and slipping agent when the tire is intact. The wheel load working on the support sections at the beginning of an emergency operation brings the sealing lips into an open position, whereby the slipping agent is released and lubricates the surfaces of the pneumatic tire and the emergency operation ring in contact with each other.

  • Patent number: 4371024
    Abstract: The invention relates to an emergency running ring for pneumatic tires mounted on vehicle rims. A lubricant is contained in cavities formed by virtue of the shape of the ring, or is contained in auxiliary members mounted in openings in the ring or mounted on the surface of the ring. In all instances, the loss of tire pressure due to emergency conditions causes the lubricant to be released so as to reduce the friction between the inner face of the tire cover and the ring.

  • Patent number: 4295509
    Abstract: An emergency track ring for a tubeless pneumatic tire comprising a bottom reinforced flange for mounting the ring on such a tire rim. At least one opening is formed in the ring to permit air to be admitted to the interior of the tire. Groove means are formed in the ring for filling with a lubricating material, and sealing lips close the groove means and seal the lubricant therein when the tire is mounted on said rim and under pressure. Flange means are integrally formed with the sealing lips and extend upwardly for engagement by the inside of the tire cover during loss of air, the depressing of the flange means effecting a lever action which causes the sealing lips to move so as to open the grooves and permit and lubricating material to be released to reduce friction between the tire cover and the track ring.

  • Patent number: 3952788
    Abstract: A pleated curtain comprising a supporting tape attached to the upper edge on the back side of the curtain, a hanger means, and a plurality of tapes, affixed vertically on the curtain is disclosed. The tapes are divided into alternatingly reinforced and unreinforced segments with cord-guiding loops affixed at the level of each second pleat fold line. Pull cords, guided by the loops and hanger means, are attached to the bottom portion of the curtain. When operated simultaneously, the pull cords evenly raise the curtain and thereby place it into pleats which extend horizontally across the width of the curtain.
