Abstract
Abstract An apparatus for the production of a synthetic resin skin uses a mold for forming at least two separate skin sections which are then joined prior or after a final heat treatment. The synthetic resin skin sections are produced in at least two separate mold members, and the skin sections are then caused to contact each other along determined faces or margins which are joined under light pressure. Any so-called selvage is easily removed after the joining which intimately bonds the skin sections to each other due to the curing of the synthetic resin.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
265 words
An apparatus for producing three-dimensionally shaped thin skin portions of synthetic material, said skin portions having edges to be joined to each other to form substantially a butting joint between neighboring skin portions, comprising a mold section having a first flange (54) extending from a wall of said mold section, a container section for holding an uncured synthetic material, said container section having a second flange (70) extending from a wall of said container section for cooperation with said first flange in joining said mold section to said container section for a skin portions molding operation, said first flange of said mold sections comprising a pinching edge (50) for reducing a thickness of a skin portion edge, a first support surface (51) closely spaced from said pinching edge (50), a groove (43) between said pinching edge (50) and said first support surface (51), a second support surface (52) spaced from said first support surface (51), a recess (53) between said first and second support surfaces (51 and 52), said first flange extending from said mold section wall a distance greater than the distance said second flange extends from said container section wall such that, when said first and second flange cooperate with each other in said skin portion molding operation, said pinching edge (50), said groove, said first support surface (51), and at least a portion of said recess (53) being open for communicating with said container section for receiving said uncured synthetic material whereby a subsequently usable selvage skin rim is formed on said pinching edge, in said groove, and on said recess portion.
Claim 2
Independent Claim
265 words
An apparatus for producing three-dimensionally shaped thin skin portions of synthetic material, said skin portions having edges to be joined to each other to form substantially a butting joint between neighboring skin portions, comprising a mold section having a first flange (54) extending from a wall of said mold section, a container section for holding an uncured synthetic material, said container section having a second flange (70) extending from a wall of said container section for cooperation with said first flange in joining said mold section to said container section for a skin portions molding operation, said first flange of said mold sections comprising a pinching edge (50) for reducing a thickness of a skin portion edge, a first support surface (51) closely spaced from said pinching edge (50), a groove (43) between said pinching edge (50) and said first support surface (51), a second support surface (52) spaced from said first support surface (51), a recess (53) between said first and second support surfaces (51 and 52), said first flange extending from said mold section wall a distance greater than the distance said second flange extends from said container section wall such that, when said first and second flange cooperate with each other in said skin portion molding operation, said pinching edge (50), said groove, said first support surface (51), and at least a portion of said recess (53) being open for communicating with said container section for receiving said uncured synthetic material whereby a subsequently usable selvage skin rim is formed on said pinching edge, in said groove, and on said recess portion.
Claim 3
Dependent Claim
29 words
The apparatus of claim 1, wherein said first flange has a rib (77) projecting freely into said container section, at least said pinching edge being located on said rib.
Claim 4
Dependent Claim
22 words
The apparatus of claim 2, wherein said groove (43) and said first support surface (51) are also located in said rib (77).
