Simple pressure seal methods

A method of handling a business form having patterns of pressure activated cohesive, using first and second fold rollers, and first, second and third pressure-seal rollers, first and second fold plates, and a holding device above the first and second pressure-seal rollers, comprising substantially automatically:

• (a) feeding a business form having patterns of pressure activated cohesive between the first and second fold rollers and into the first fold plate, to introduce a first fold therein;
• (b) feeding the form from the first fold plate to between the first fold roller and the third pressure-seal roller and then to the second fold plate to introduce a second fold therein;
• (c) feeding the form from the second fold plate to between the third and first pressure-seal rollers to effect activation of pressure activated cohesive on the form, and to the holding device above the first and second pressure-seal rollers;
• and
• (d) feeding the form from the holding device to between the first and second pressure-seal rollers to effect activation of pressure activated cohesive on the form so that the form is held in folded condition.
