Abstract
A process produces foamed articles, especially foamed articles for upholstering car seats. The foamed articles include an adhesive closing part having adhesive elements incorporated into the foaming mold generating the foamed article and covered by a foam-protecting cover. The adhesive closing part itself constitutes the cover. A lateral cover of the adhesive closing part whose width overlaps the surface area on which the adhesive elements are arranged and is releasably attached to the foaming mold by a fixing device. This design simplifies the foaming process and keeps production costs low.
Claims11
A process for producing a foamed part having at least one adhesive closing part with adhesive elements, comprising the steps of:
- forming a one-piece, unitary adhesive closing part including a base with adhesive elements extending in a first direction from one surface thereof, said base having variable width edge portions free of adhesive elements such that said base forms a foam retaining cover projecting laterally beyond an area of the base supporting the adhesive elements, the cover having ferromagnetic components formed as an integral part thereof;
- placing the adhesive closing part in a foam injection mold such that free ends of the adhesive elements are arranged substantially in one plane, substantially perpendicular to the first direction and substantially parallel to the one surface at the base, with the edge portions of the adhesive closing part and in separable contact with the foam injection mold, the adhesive closing part being releasably retained in place in the foam injection mold by a retaining mechanism;
- and
- injecting molding material into the mold to produce the foamed part.
An adhesive closing part for use in a process for producing a foamed part with the adhesive closing part thereon, comprising:
- a cover having edge portions and ferromagnetic properties as an integral part thereof, said edge portions having a mold engaging surface on a first side of said cover;
- and
- adhesive elements extending directly from said first side of said cover in a first direction between said edge portions, said edge portions being free of said adhesive elements, said adhesive elements having free ends substantially coplanar with said mold engaging surface of said edge portions of said cover in a plane substantially perpendicular to said first direction and substantially parallel to said first side, said adhesive elements being formed unitarily as one piece with said cover.
