Short length mailer structure and method of manufacture

Claim 2

A business form having a plurality of fold lengths for mailer usage comprising top and bottom piles having longitudinally extending edges, at least one edge being equipped with a control margin, at least one intermediate ply between said top and bottom piles and including a series of at least two form lengths constituting a fold length, said top and bottom piles having transverse lines of weakness every form length and a line of potential folding at each fold length, said intermediate ply terminating a spaced distance short of said lines of potential folding and further being partially discontinuous about each line of weakness, and adhesive means joining said plies together.

Claim 3

The form of claim 1 in which said intermediate ply has a pair of laterally extending edges, said intermediate ply having a minor longitudinal attaching portion continuous between said intermediate ply edges to provide the partial discontinuity.

Claim 4

The form of claim 2 in which said minor longitudinal portion is adjacent one of said intermediate ply edges.

Claim 5

The form of claim 2 in which one of said intermediate ply laterally extending edges is generally coincident with one of said top and bottom ply longitudinally extending edges.

Claim 6

A business form having a plurality of fold length suitable for mailer usage comprising top and bottom plies having longitudinally extending edges, at least one edge being equipped with a control margin, at least one intermediate ply between said top and bottom plies and including a series of at least two form lengths constituting a fold length, said top and bottom plies having transverse lines of weakness every form length and a line of potential folding at each fold length, said form length not being greater than about 41/4". said intermediate ply terminating a spaced distance short of said lines of potential folding and further being partially discontinuous about each line of weakness, and adhesive means joining said plies together.

Claim 7

A business form having a plurality of fold length suitable for mailer usage comprising top and bottom plies having longitudinally extending edges, at least one edge being equipped with a control margin, at least one intermediate ply between said top and bottom plies and including a series of at least two form lengths constituting a fold length, said top and bottom plies having transverse lines of weakness every form length and a line of potential folding at each fold length, said form length not being greater than about 41/4". said intermediate ply terminating a spaced distance short of said lines of potential folding and further being partially discontinuous about each line of weakness, and adhesive means joining said plies together.
