    Abstract: THE CONTINUOUS MOLDING OF AN ELASTOMERIC SEALING STRIP ON A TAPE FOR A SLIDE FASTEER IN WHICH A PERFORMED STRIP OF ELASTOMERIC MATERIAL IS APPLIED TO A TAPE AS IT IS CONTINUOUSLY FED INTO A MOLD CAVITY ON THE PERIPHERY OF A ROTATING HEATING CURING DURM. THE TAPE AND PERFORMED STRIP ARE ENCLOSED IN THE MOLD CAVITY BY A METAL BELT WRAPPED AROUND A PORTION OF THE CURING DURM AND DRIVEN AT THE SAME SPEED AS THE DRUM. THE MOLDED ELASTOMERIC SEALING STRIP AND TAPE ARE ENCLOSED IN THE MOLD CAVITY AT A MOLDING TEMPERTURE FOR A PERIOD OF TIME NECESSARY TO CURE THE SEALING STRIP ON THE TAPE AFTER WHICH THE TAPE IS RELEASED AND CARRIED AWAY FROM THE CURING DRUM.

    Abstract: A sealing closure between two margins of sheet material in which each margin has a sealing strip continuously applied to one face of the margin at a position spaced from the edge thereof and interlocking teeth of a slide fastener fastened to the edge of the margin at the sides of the teeth so that the edges are turned under and the teeth overlie the other face of the margin when the slide fastener is in the locked position. As the slide fastener closes, sealing lips on the sealing strips are pulled into engagement and resiliently oppose the forces produced by the turning under of the edges of the margins.

    Abstract translation: 在片材的两个边缘之间的密封封盖,其中每个边缘具有在与边缘间隔开的位置处连续地施加到边缘的一个面的密封条,并且紧固在边缘边缘处的拉链的互锁齿 的齿,使得当拉链处于锁定位置时,边缘被翻转并且齿覆盖边缘的另一个面。 当拉链关闭时,密封条上的密封唇被拉入接合状态并且弹性地抵靠在边缘边缘处转动产生的力。
