A machine for manufacturing flat bottom bags includes a drum for carrying along at least one blank having a flattened tubular shape in an advancing direction, a first scoring apparatus upstream of the drum for marking on the blank a first folding line which is transverse with respect to the advancing direction, a front gripper on the drum that grips a front edge of the blank on the drum, in an opening step, and and carries along the blank, a first lateral gripping means on the drum that grip the lateral edges of the blank in the region of the first folding line.

A system includes a film processing module, a processor, and memory. The processor and memory are in communication with the film processing module. The processor is configured to dynamically coordinate movement of the film processing module relative to a moving web of film and to perform a function on the web of film with the film processing module.

A joint apparatus that joins a pouch body to a spout, including: a spout holding unit that holds the spout; a positioning mechanism that positions the pouch body with respect to the spout; and a joint mechanism that joins a pouch mouth of the pouch body to the spout. The positioning mechanism has a pouch-body moving unit that moves the pouch body toward the spout a contact member having a contact part that comes into contact with an end of the pouch mouth, and an absorption mechanism that absorbs a part of a force acting on the pouch body when the end of the pouch mouth comes into contact with the spout or the contact member.

The device for cooling an adhesive applied to a surface of bag bodies includes a transfer conveyor and a cooling conveyor. The transfer conveyor conveys the bag bodies at a transfer speed to the cooling conveyor, and the cooling conveyor conveys the bag bodies taken over from the transfer conveyor at a cooling conveyor speed. The transfer speed is higher than the cooling conveyor speed, which is why the bag bodies are arranged overlapping each other on the cooling conveyor. Due to this higher packing density, there is achieved a long dwell time of the bag bodies in the cooling conveyor at simultaneously a high flow-rate of bag bodies through the device.

The present disclosure providing a cushion pad includes at least one cushion unit including at least one die-cutting region, a length of the die-cutting region increased when the die-cutting region is unfolded; the die-cutting region is unfolded to form a buffer layer that causes the second surface to expand in a thickness direction of the second surface to play a buffering and protective role thereof; the die-cutting region is unfolded to form a three-dimensional network structure. The present disclosure also provides that a packaging bag with the cushion unit is of a plane structure after production; when the packaging bag is used after being transportation, an object is put into the packaging bag or applying a pushing force to the packaging bag so that the cushion unit is expanded to form the buffer layer, to protect the object inside the packaging bag.

A machine and method for converting film into bags or other articles includes a web traveling from an input section to a rotary drum, to an output section. The rotary drum includes at least one seal bar with a sealing zone and a weakening zone, or it can include or at least one sealing die that extends in the machine direction. The single sealing zone or sealing die may be a heated perforator, and may include a heating wire. The heating wire may be an NiCr wire stitched into the heater, and be disposed on a cap or on the seal bar. The weakening zone may create a line of weakness that is uniform or varies in intensity. The sealing zone may include temperature zones, cartridge heaters, cooling air, or heated air, or a source of ultrasonic, microwave or radiative energy.

A system includes a film processing module, a processor, and memory. The processor and memory are in communication with the film processing module. The processor is configured to dynamically coordinate movement of the film processing module relative to a moving web of film and to perform a function on the web of film with the film processing module.

The present invention relates to a method for forming packages of flexible material with a first side gusset and a second side gusset starting from a strip coming from a reel having a sliding direction. The method comprises the following steps: making the first gusset by folding close to a first side edge of the strip coming from the reel, and making the second gusset by folding the strip coming from the reel; in which the step of making the second gusset is performed on a portion of the strip which extends in the sliding direction after the step of making the first gusset was performed on the portion of the strip. Moreover, the present invention relates to a machine configured so as to carry out the method.

A system includes a film processing module, a processor, and memory. The processor and memory are in communication with the film processing module. The processor is configured to dynamically coordinate movement of the film processing module relative to a moving web of film and to perform a function on the web of film with the film processing module.

The present disclosure provides a cushion sheet production module configured to synchronously and continuously feed first and second surfaces, roll to apply a plurality of first horizontal glues on the first and second surfaces along a direction perpendicular to a feeding direction, the plurality of first horizontal glues arranged at intervals between each other, and continuously apply first longitudinal glues on both sides of the first surface or the second surface facing each other; and then, the first and second surfaces are pressed together to fix with each other at positions of the first horizontal and longitudinal glues, to form a cushion sheet, wherein gas is sealed between the first and second surfaces; or, a buffer layer added between the first and second surfaces to fix the first and second surfaces and the buffer layer together at the first horizontal and longitudinal glues, to form the cushion sheet.
