Abstract
Abstract A shaped article, such as a floor covering for a vehicle, is made from a plurality of interconnected sections of fabric having a pile and including a thermosetting or thermoplastic plastics material. During forming of the article on a two-part press, in order to prevent the pile from being flattened, the pile surface of the joined together and properly oriented sections is engaged by a gridlike press part only in the regions of the joints between the section. The press includes a trough-shaped receiving press part and a pivotally mounted top press part which is movable to engage over the article which is positioned in the trough-shaped part. The top press part is favored as a grid with projecting portions such as tubes which engage the article being formed at least at the junctures of sections or portions of the article which are to be arranged at an angle to one or more other portions. The tubes advantageously carry means for selectively cooling or heating the article to apply a desired thermal treatment for permanently forming the article.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
185 words
A multipart molding press for the manufacture of an article having a selected three-dimensional shape with the article being formed at least in part of a shaping layer consisting of a synthetic resin material and another layer consisting of a fabric, comprising separate press parts shaped to provide the article with its selected three-dimensional form and arranged to be pressed together to exert a pressing force directly on the layers forming the article, at least one of said press parts arranged to provide a base part on which the layers to be formed into the article are placed, wherein the improvement comprises at least one other of said press parts comprising a plurality of interconnected rodlike members forming a lattice-shaped press part with lattice openings between said rodlike members through which the layer adjacent to said lattice-shaped press part can be observed when said press parts are moved together, whereby any misalignment of the layer can be corrected, and said rodlike members being arranged to exert narrow bands of pressure application to the layers for joining the layers forming the article along the narrow bands.
Claim 2
Dependent Claim
185 words
A multipart molding press for the manufacture of an article having a selected three-dimensional shape with the article being formed at least in part of a shaping layer consisting of a synthetic resin material and another layer consisting of a fabric, comprising separate press parts shaped to provide the article with its selected three-dimensional form and arranged to be pressed together to exert a pressing force directly on the layers forming the article, at least one of said press parts arranged to provide a base part on which the layers to be formed into the article are placed, wherein the improvement comprises at least one other of said press parts comprising a plurality of interconnected rodlike members forming a lattice-shaped press part with lattice openings between said rodlike members through which the layer adjacent to said lattice-shaped press part can be observed when said press parts are moved together, whereby any misalignment of the layer can be corrected, and said rodlike members being arranged to exert narrow bands of pressure application to the layers for joining the layers forming the article along the narrow bands.
Claim 3
Dependent Claim
21 words
A multipart molding press, as set forth in claim 1, characterized in that said rodlike members being formed of solid bars.
Claim 4
Dependent Claim
30 words
A multipart molding press, as set forth in claim 1, characterized in that said rodlike members being tubular in form with the passages therein interconnected for circulating a liquid therethrough.
Claim 5
Dependent Claim
79 words
A multipart molding press, as set forth in claim 3, characterized in that a hollow pivot member being arranged for pivotally mounting said other one of said press parts so that said other one of said press parts can be pivotally displaced relative to the one of said press parts forming the base part, said tubular rodlike members being in fluid communication with said hollow pivot member for circulating a fluid from said pivot member through said rodlike members.
Claim 6
Dependent Claim
39 words
A multipart molding press, as set forth in claim 1, characterized in that the interconnected said rodlike members having a three-dimensional shape arranged to mate with and correspond to the shape of said press part forming the base part.
Claim 7
Dependent Claim
75 words
A multipart moldIng press, as set forth in claim 1, characterized in that the layers to be formed into the article being composed of a multiple number of individual layer parts each defining a different curved or flat plane surface of the article, and the other one of said press parts having its rodlike members disposed along at least the joints between the different plane surfaces of the article formed by the individual layer parts.
Claim 8
Dependent Claim
91 words
A multipart molding press, as set forth in claim 1, characterized in that wall means in combination with the one of said press parts providing the base part forming a closed chamber subjacently arranged to the one of said press parts, the one of said press parts having a plurality of perforations therethrough communicating with the closed chamber, means connected to said closed chamber for establishing a suction therein acting through the perforations in the one of said press parts on the layers placed on the one of said press parts.
