Abstract
A system includes a forming funnel, a cutting element, and a fusing device. The forming funnel has divergent surfaces arranged to receive a mailer in an insertion direction between the divergent surfaces. The forming funnel includes a slot that constrains the mailer after the mailer is inserted between the divergent surfaces. The cutting element cuts off a portion of the mailer and to forms a cut end of the mailer as the mailer is moved through the slot in a sliding direction. The fusing device applies pressure to an exterior of the cut end of the mailer and applies heat to the cut end of the mailer as the mailer is moved through the slot. The pressure and the heat applied by the fusing device cause portions of the cut end to fuse together to close the mailer.
