  • Patent number: 11986981
    Abstract: A method for forming a silicone container having a reinforced rim. A layer of adhesive is applied to the outer surface of a metal ring. The adhesive layer is covered with a first plug of unvulcanized silicone. The first plug of unvulcanized silicone is then vulcanized to form a vulcanized silicone covered metal ring. The vulcanized silicone covered metal ring is then inserted into a mold along with a second plug of unvulcanized silicone. The second plug of unvulcanized silicone is then vulcanized so that it binds with the vulcanized silicone covered metal ring to form a silicone container having a reinforced rim. In one preferred embodiment the silicone container having a reinforced rim is a bowl. In another preferred embodiment the silicone container having a reinforced rim is a cup.

    Abstract: The invention relates to a method for automatically regulating the size of a nozzle discharge slot of a nozzle assembly, wherein the nozzle assembly comprises a first and a second nozzle lip and a nozzle discharge slot arranged between the nozzle lips for setting in a controlled manner a thickness profile of a conveyable melt. A plurality of adjusting elements, in particular a plurality of adjusting pins, coupled to a respective thermoelement, is arranged on the first nozzle lip, the thermoelements being controllable by the regulation in such a way that the slot can be adjusted by the action of a mechanical force from the respective adjusting element on the first nozzle lip, as a result of the expansion or contraction of the thermoelements. At an initial operation of the nozzle assembly for conveying the melt, the adjusting elements for subsequent regulation of the slot size are set uniquely free from play as the initial setting. The invention further relates to a control and/or regulation system.
