In the production of mailer type business forms, particularly from a web in a roll configuration having a plurality of business form intermediates, with pressure sensitive cohesive, the problem of cohesive blocking (sticking together) at inopportune times is avoided by spacing substantially linear patterns of the cohesive disposed in the detachable side edges of the intermediates so that when the intermediates are in the roll configuration the cohesive from one intermediate does not engage the cohesive from another. Preferably the cohesive patterns on one face of the intermediate are spaced from the parallel cohesive patterns on the second face of the intermediate by about 1-15 mm, preferably about one centimeter. Transversely extending patterns of cohesive also may be positioned so that they too do not engage in the roll configuration, even though engagement of the transverse patterns is much less of a problem because the potential areas for engagement are few when the intermediates are in the roll configuration.
