ABSTRACT:
A pressure sealer for sealing pressure sensitive adhesive strips on business forms has only a single set of sealing rollers forming a nip. One roller is gear driven by a D.C. motor, and a spring applies a biasing force to press the rollers into contact with each other. A forward sensor and a reverse sensor are positioned just before the nip of the rollers, in or above a support surface for business forms, and cooperate with a computer chip to control the motor to drive a business form in a first direction between the rollers, until it has almost completely passed through the nip. Then the motor is reversed to drive the business form through the nip again in a second direction opposite the first direction. The business form is manually fed to, and removed from, the nip.
