Abstract
Abstract Flat articles, such as letterheads, having a surface, are processed by laying an insert onto the surface, applying adhesive to the surface in a pattern at least partially surrounding the insert and applying sheet means, such as paper, into overlying relation with the insert and into contact with the adhesive pattern forming a pocket containing the insert, all while continuously propelling the articles along the path.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
149 words
A method of producing articles having a surface supporting sheet means forming a pocket containing a removable insert comprising: a. propelling said articles along a path with said surface exposed; b. applying said removable insert from a remote location into overlying, contacting, impermanent relation with said surface, said removable insert being of smaller size than said surface whereby said surface is partially covered by said removable insert and exposed over an area located beyond a substantial peripheral portion of said removable insert; and c. applying said sheet means from a remote location into at least partially overlapping relation with said removable insert and into adhesive contact with said area forming a pocket at least partially containing said insert and having an opening sufficient to withdraw said removable insert therefrom, d. the application of said removable insert and sheet means being performed while continuously propelling said articles along said path.
Claim 2
Independent Claim
149 words
A method of producing articles having a surface supporting sheet means forming a pocket containing a removable insert comprising: a. propelling said articles along a path with said surface exposed; b. applying said removable insert from a remote location into overlying, contacting, impermanent relation with said surface, said removable insert being of smaller size than said surface whereby said surface is partially covered by said removable insert and exposed over an area located beyond a substantial peripheral portion of said removable insert; and c. applying said sheet means from a remote location into at least partially overlapping relation with said removable insert and into adhesive contact with said area forming a pocket at least partially containing said insert and having an opening sufficient to withdraw said removable insert therefrom, d. the application of said removable insert and sheet means being performed while continuously propelling said articles along said path.
Claim 3
Independent Claim
149 words
A method of producing articles having a surface supporting sheet means forming a pocket containing a removable insert comprising: a. propelling said articles along a path with said surface exposed; b. applying said removable insert from a remote location into overlying, contacting, impermanent relation with said surface, said removable insert being of smaller size than said surface whereby said surface is partially covered by said removable insert and exposed over an area located beyond a substantial peripheral portion of said removable insert; and c. applying said sheet means from a remote location into at least partially overlapping relation with said removable insert and into adhesive contact with said area forming a pocket at least partially containing said insert and having an opening sufficient to withdraw said removable insert therefrom, d. the application of said removable insert and sheet means being performed while continuously propelling said articles along said path.
Claim 4
Independent Claim
149 words
A method of producing articles having a surface supporting sheet means forming a pocket containing a removable insert comprising: a. propelling said articles along a path with said surface exposed; b. applying said removable insert from a remote location into overlying, contacting, impermanent relation with said surface, said removable insert being of smaller size than said surface whereby said surface is partially covered by said removable insert and exposed over an area located beyond a substantial peripheral portion of said removable insert; and c. applying said sheet means from a remote location into at least partially overlapping relation with said removable insert and into adhesive contact with said area forming a pocket at least partially containing said insert and having an opening sufficient to withdraw said removable insert therefrom, d. the application of said removable insert and sheet means being performed while continuously propelling said articles along said path.
