Abstract
Abstract The apparatus includes a first female mold member defining a shaped mold cavity for receiving a plastisol layer or skin. A second mold member is pivotally disposed on the female mold member between an open and closed position. In the open position, the second mold member receives and holds thereon a portion of the plastisol skin extending from the mold cavity. An insert is positioned in the mold cavity by a third mold member such as a mold lid on which the insert is releasably retained. After the insert is positioned in the mold cavity, the second mold member is pivoted toward the mold lid to fold the skin portion thereon over and against an edge of the insert. The skin is folded adjacent the pivot axis of the second mold member. Foam can then be introduced and cured between the skin and insert.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
202 words
An apparatus useful for molding a composite article having an outer layer and an insert with foam therebetween, comprising: (a) a first mold member having a first surface defining a mold cavity for receiving the layer thereon, (b) a second mold member having a second surface thereon generally contiguous with the first surface when the second mold member is in an open position for receiving and carrying thereon a portion of said layer extending from the first surface, (c) a third mold member for positioning an insert in the cavity when the second mold member is in the open position with the insert spaced from the layer in the mold cavity, (d) said second mold member being movable to a closed position between the first mold member and third mold member after the third mold member positions the insert in the mold cavity so as to move said portion of the layer thereon toward the insert positioned in the mold cavity and fold said portion of the layer onto the insert as a result of said movement of said second mold member to said closed position, and (e) means for moving said second mold member between the open position and closed position.
Claim 2
Independent Claim
202 words
An apparatus useful for molding a composite article having an outer layer and an insert with foam therebetween, comprising: (a) a first mold member having a first surface defining a mold cavity for receiving the layer thereon, (b) a second mold member having a second surface thereon generally contiguous with the first surface when the second mold member is in an open position for receiving and carrying thereon a portion of said layer extending from the first surface, (c) a third mold member for positioning an insert in the cavity when the second mold member is in the open position with the insert spaced from the layer in the mold cavity, (d) said second mold member being movable to a closed position between the first mold member and third mold member after the third mold member positions the insert in the mold cavity so as to move said portion of the layer thereon toward the insert positioned in the mold cavity and fold said portion of the layer onto the insert as a result of said movement of said second mold member to said closed position, and (e) means for moving said second mold member between the open position and closed position.
Claim 3
Dependent Claim
19 words
The apparatus of claim 1 further including means for holding said portion of the layer on said second surface.
Claim 4
Dependent Claim
36 words
The apparatus of claim 2 wherein said holding means comprises means for creating a differential pressure on opposite sides of the layer so that the layer is held on the second mold member by differential pressure.
Claim 5
Dependent Claim
43 words
The apparatus of claim 1 wherein the second mold member is pivotably mounted on the first mold member about a pivot axis for pivotal movement between the open position and closed position to fold said portion of the layer adjacent said pivot axis.
Claim 6
Dependent Claim
24 words
The apparatus of claim 1 wherein the second mold member folds said portion of layer over and against the insert in the closed position.
Claim 7
Dependent Claim
19 words
The apparatus of claim 5 wherein the second mold member in the closed position overlies the third mold member.
Claim 8
Dependent Claim
32 words
The apparatus of claim 1 wherein said means for moving the second mold member between the open position and closed position comprises an actuator means operably connected to said second mold member.
