Abstract
A closure part, for vulcanization into products which are produced at least in part by vulcanization, includes at least a rear side, a function side and a barrier layer. The rear side is integrally bonded to a rubber material. The function side has individual hook-and-loop elements that are kept free of the rubber material and produce a releasable hook-and-loop closure when engaged with corresponding hook-and-loop elements. The barrier layer is between the rear and the function side. The barrier layer prevents liquid rubber material and/or flowable vulcanization products from entering the function side from the rear side during vulcanization.
Claims18
A closure part configured for vulcanizing into products which are produced at least in part by vulcanization, the closure part at least consisting of:
- a rear side, which can be bonded to a rubber material by integral bonding;
- a function side, which has individual hook-and-loop elements that are kept free of the rubber material and produce a releasable hook-and-loop closure when engaged with corresponding hook-and-loop elements;
- and
- a barrier layer between the rear and the function side, which barrier layer prevents liquid rubber material and/or flowable vulcanization products from entering the function side from the rear side during vulcanization.
A method for producing a vulcanization product, being at least one rubber mat, comprising at least the following method steps:
- inserting the closure part with a rear side into a still soft plastic rubber material mass;
- performing a vulcanization process by applying a pressure and a temperature to the connection of the closure part to the plastic rubber material mass;
- and
- removing the finished vulcanization product after the vulcanization, during which the hook-and-loop elements of the function side project past the elastic rubber material mass.
