Laminated metals sheet composite and method for making such sheet
View Patent ↗A composite product for use in a motor vehicle body and a method and apparatus for producing that product is disclosed. The product has a first blank with a predetermined thickness, a second blank with a predetermined thickness and dimensioned to provide the composite product with a combined thickness of the first and second blanks only in at least one required area of the composite product. A wire mesh layer is provided between the first and second blanks. An adhesive is selected to bond the first and second blanks together with the wire mesh layer interposed therebetween.
1. A method of producing a composite blank for use in making a motor vehicle body, comprising:
producing at least one first blank having a predetermined thickness, comprising:
unrolling a coil of thin metal;
forming a plurality of first blanks such that adjacent first blanks are oriented in opposite directions relative to a direction of the unrolling;
separating the adjacent first blanks into two columns, in each of which columns the first blanks have the same orientation; and
applying adhesive to at least one area of the first blanks in each column and moving the two columns of the first blanks to an assembly location;
producing at least one second blank having a predetermined thickness and being shaped to provide the composite blank with a combined thickness of the first and second blanks in at least one required area of the composite blank;
supplying at least one wire mesh member having a shape and size similar to the at least one second blank; and
joining the at least one first and second blanks with the at least one wire mesh member interposed therebetween by adhesive bonding.
2. A method according to claim 1 , wherein the producing of the at least one wire mesh member comprises unrolling a coil of wire mesh material; forming a plurality of wire mesh members such that adjacent wire mesh members are oriented in opposite directions relative to a direction of the unrolling; separating the adjacent wire mesh members into two columns, in each of which columns the wire mesh member have the same orientation; turning one of the columns of the wire mesh members by 180° so that the wire mesh members in one of the columns are oriented as mirror images of the wire mesh members in the other column; and moving the two columns of the wire mesh members to an assembly location.
3. A method according to claim 1 , wherein the producing of the at least one second blank comprising unrolling a coil of thin metal; forming a plurality of second blanks such that adjacent second blanks are oriented on opposite directions relative to a direction of the unrolling; separating the adjacent second blanks into two columns, in each of which columns the second blanks have the same orientation; turning one of the columns of the second blanks by 180° so that the second blanks in one of the columns are oriented as mirror images of the second blanks in the other column, and moving the two columns of the second blanks to an assembly location.
4. A method according to claim 1 , wherein the producing of the at least one wire mesh member comprises unrolling a coil of wire mesh material; forming a plurality of wire mesh members such that adjacent wire mesh members are oriented in opposite directions relative to a direction of the unrolling; separating the adjacent wire mesh members into two columns, in each of which columns the wire mesh member have the same orientation; turning one of the columns of the wire mesh members by 180° so that the wire mesh members in one of the columns are oriented as mirror images of the wire mesh members in the other columns, and moving the two columns of the wire mesh members to the assembly location.
5. A method according to claim 4 , wherein the producing of the at least one second blank comprising unrolling a coil of thin metal; forming a plurality of second blanks such that adjacent second blanks are oriented on opposite directions relative to a direction of the unrolling; separating the adjacent second blanks into two columns, in each of which columns the second blanks have the same orientation, turning one of the columns of the second blanks by 180° so that the second blanks in one of the columns are oriented as mirror images of the second blanks in the other column, and moving the two columns of the second blanks to the assembly location.
6. A method according to claim 5 , wherein the joining takes place at the assembly location.
