A unit for over-wrapping filter bags includes a carousel rotating about a first axis with first and second grippers along a closed circular trajectory. A forming station for forming single sheets of over-wrapping material is arranged near the trajectory and includes a feeding device for feeding the sheets in a U-shape, synchronized with the first grippers. A first drum transports formed bags, rotates about a second axis and has grippers receiving the bags from a preceding station and releasing the bags from the first grippers with the U-shaped sheets in synchronization. A closing station includes a sealing gripper movable from a first position near the carousel, for picking the bag with the sheet the first gripper, to a second away position for closing the sheet and, lastly, to a third position near the carousel, for release of the enclosed bag to the second gripper.

This disclosure relates to a cashbag sealing system. The system comprises a banknote transport mechanism operable to transport a banknote to a storing unit. The storing unit includes a banknote storing bag detachably coupled to the storing unit, and an escrow plate operable to escrow the banknote before the banknote transported to the storing unit is stored in the banknote storing bag, wherein the escrow plate is operable to move from a horizontally extending hold position to a downwardly or obliquely downwardly extending release position, and wherein the banknote transported to the storing unit is escrowed on the escrow plate when the escrow plate is located at the hold position. The system further comprises a sensor configured to detect a presence of the banknote on the escrow plate, and measure a level of banknotes in the banknote storing bag.

A bag clamping device for a material bag filling system is provided. A filling tube portion of a material bag can be blown to be in an upright state from a collapsed state through displacement and lift of an X-axis rail, a Y-axis rail and a Z-axis rail and blow of a pair of blowers. A pair of electric clamps is configured to clamp the filling tube portion. A pair of cantilevers is displaced to the bottom of a material filling device. The filling tube of the material filling device is displaced in a Z direction to enter the material bag for blowing air and filling the material. Through a conveyor belt displaced at the bottom in an X direction to carry the material bag with the filled material to a sealing device for sealing, so as to complete the packaging.

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.
