Abstract
Abstract The invention relates to a method for making a surface-lined shaped article, particularly an interior facing member for a motor vehicle, such shaped article having a backing member which is heated in an undeformed state and then inserted into a temperature-adjusted die assembly in which a liner material is provided facing the finally visible surface of the backing member to which it is bonded as the backing member is being deformed or shaped. An object of the present invention is the provision of a method of the type defined above which permits a shaped article to have at least two surface areas thereof lined with different liner materials in a simple and economical manner. For attaining this object, the invention provides that the surface liner material is clamped in the die assembly in the form of at least two cuttings covering different areas of the backing member, and the backing member is brought into pressure contact with the clamped cuttings along at least one overlap or abutment line, or a connection line, respectively, by means of gripper elements acting from above and below, prior to the backing member being deformed together with the cuttings.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
190 words
A method for making a shaped article particularly as an interior facing shaped article for a motor vehicle, the shaped article including a backing member and surface lining material, comprising the steps of positioning surface material in a temperature adjusted die assembly in the form of at least two cuttings having at least one overlap or abutment therebetween, clamping the surface material in the die assembly, heating a backing member in its undeformed state, introducing the heated undeformed backing member into the die assembly with the surface material and backing member facing one another, applying pressure on both sides of the clamped surface material and backing member to bring them into pressure contact with one another along the overlap or abutment, the pressure being applied by gripper element means on each side thereof respectively carried by the die assembly, and closing the die assembly to deform the surface material and backing member together to bond the surface material and backing member to one another and to form the surface material and backing member into the finally shaped article having the two cuttings bonded to different areas of the backing member.
Claim 2
Independent Claim
190 words
A method for making a shaped article particularly as an interior facing shaped article for a motor vehicle, the shaped article including a backing member and surface lining material, comprising the steps of positioning surface material in a temperature adjusted die assembly in the form of at least two cuttings having at least one overlap or abutment therebetween, clamping the surface material in the die assembly, heating a backing member in its undeformed state, introducing the heated undeformed backing member into the die assembly with the surface material and backing member facing one another, applying pressure on both sides of the clamped surface material and backing member to bring them into pressure contact with one another along the overlap or abutment, the pressure being applied by gripper element means on each side thereof respectively carried by the die assembly, and closing the die assembly to deform the surface material and backing member together to bond the surface material and backing member to one another and to form the surface material and backing member into the finally shaped article having the two cuttings bonded to different areas of the backing member.
Claim 3
Dependent Claim
30 words
A method according to claim 1 wherein the pressure application step bonds the surface material to the backing member along said overlap or abutment before the die assembly closing step.
Claim 4
Dependent Claim
29 words
A method according to either claim 1 or 2 wherein the positioning step includes supplying the surface material in the form of a web material in a tensioned state.
Claim 5
Dependent Claim
163 words
Apparatus for making a shaped article particularly as an interior facing member for a motor vehicle, said shaped article including a backing member (2) and a surface liner material having at least two cuttings (7, 8) with at least one overlap or abutment therebetween, said apparatus comprising a die assembly having an upper and lower die portion (11, 12) movable relative to one another between open and closed positions, a gripper element (13, 14) carried by each upper and lower die portion in opposition to one another, said gripper elements in the open die position, projecting from their respectively associated die portions into their gripping position to apply pressure to opposite sides of the backing member and surface material positioned therebetween along the overlap or abutment (cf FIG. 1), said gripper elements retracting into their associated die portions against the force of resistance element means (24) as the dies close to bond and deform the backing member and surface liner material positioned therebetween.
Claim 6
Dependent Claim
163 words
Apparatus for making a shaped article particularly as an interior facing member for a motor vehicle, said shaped article including a backing member (2) and a surface liner material having at least two cuttings (7, 8) with at least one overlap or abutment therebetween, said apparatus comprising a die assembly having an upper and lower die portion (11, 12) movable relative to one another between open and closed positions, a gripper element (13, 14) carried by each upper and lower die portion in opposition to one another, said gripper elements in the open die position, projecting from their respectively associated die portions into their gripping position to apply pressure to opposite sides of the backing member and surface material positioned therebetween along the overlap or abutment (cf FIG. 1), said gripper elements retracting into their associated die portions against the force of resistance element means (24) as the dies close to bond and deform the backing member and surface liner material positioned therebetween.
Claim 7
Dependent Claim
42 words
Apparatus according to claim 4 characterized in that said upper die portion (11) is provided with clamping means (16) for clamping said cuttings in a plane (E) defining the end position of said gripper element (13) in its fully extended gripping position.
