The invention relates to a valve bag, in particular a cross-bottom valve bag, comprising a first wall and a second wall, which are joined to each other by means of side edges or side folds and by means of bottoms and which delimit a bag interior, comprising a valve, which is arranged in one of the bottoms and via which the bag interior can be filled with a filling material, and comprising venting openings in the first and/or in the second wall for venting the bag interior. At least one channel is provided on the outside of at least one wall, which channel covers the venting openings and is formed at least by two parallel fastening strips and by a cover strip, the cover strip likewise comprising venting openings, and wherein the shortest path between the parallel fastening strips along the cover strip is longer than the shortest path along the at least one wall or the cover strip, and/or the parallel fastening strips consist of stretchable material.

A system and a method for closing, in an automated way, at least one package having a reversibly closeable interlocking element comprising a first complementary element and a second complementary element extending between two extremities. The system includes a pressing element, configured to press the first complementary element against the second complementary element by sliding between the two extremities, and a counteracting element, configured to stop the second complementary element when the pressing element presses the first complementary element against the second complementary element, in such a way that the first complementary element and the second complementary element interlock with each other along their entire length.

The utility model discloses a vacuum sealing machine driven by air pressure. The inner cavity of a seat body is provided with a lifting seat that slides in the vertical direction. A positive air pressure pushing mechanism for driving the lifting seat to move up and down is installed above the lifting seat. A bottom platform is arranged at the lower part of the inner cavity of the seat body. A bag opening heat sealing device is arranged on the bottom surface of the lifting seat or the top surface of the bottom platform. A control circuit is electrically connected to the bag opening heat sealing device. The lifting seat after moving downward when vacuuming or sealing is pressed against the bottom platform. The utility model has the advantages of simple structure, stable and reliable action, and lower cost.

A vacuum packing apparatus includes a box, a lid, a solenoid, a vacuum pump, a pressure gauge, a time relay, a thermal sealer and a controller. The box includes a chamber. The lid is connected to the box. The thermal sealer is located in the chamber. The controller is electrically connected to the vacuum pump, the solenoid, the thermal sealer and the time relay. The panel is electrically connected to the controller.

A modular stand-alone ultrasonic bag sealing system has an ultrasonic sealer assembly that utilizes a sonotrode and an anvil that are actuated together to form a bag seal in a bag configured therebetween. The system also has an integral control system that is physically configured on the housing of the system and runs a control software. The control software is configured to control the ultrasonic sealer assembly to close and open to seal bags. The controller may have a plurality of signal inputs for receiving input signals from a bag feeder assembly or from an auxiliary machine. The system may also have an integral bag feeder assembly that has an index roller for feeding a bag to the ultrasonic sealer assembly. The system is configured for quick integration into a process line and has versatility of communication through the control software and signal inputs and outputs.

A welding station for producing a wrapping has a support wheel and a welding device housed on the support wheel and having a head assembly that has a welding member, a support body, and a rod axially movable between a retracted position and a forward position. The support body is integral with an axial end of the rod. The welding device has an abutment assembly having an abutment member and a base assembly engaged to the support wheel. The welding device is configurable in an open configuration where the head assembly and the abutment assembly are mutually spaced, the rod is axially retracted, and the abutment member allows the wrapping to be loaded onto and removed from the head assembly, and a welding configuration where the head assembly and the abutment assembly are mutually engaged, the rod is axially forward and the abutment is engaged by the welding member.

An apparatus (1) for the packaging of products in pre-made containers (100, 101) that comprises a receiving station (2) for containers and at least two workstations (3, 4) each on one side of that receiving station; the apparatus comprising container transfer means (5) that are equipped with at least two holding groups (6, 7) prepared to hold containers in a suspended way and that can move between at least two positions, one that coincides with the container receiving station (2) and the other that coincides with one of the two workstations (3 or 4), such that the transfer means are able to serve the pre-made containers received in that receiving station to one side and to the other side of the receiving station, and to corresponding workstations, in an alternating way.

The invention relates to a bag contour welding tool for welding a foil to form an open bag, where the bag contour welding tool has a recess between two head lines, to a device for filling this bag with this bag contour welding unit, to a welding tool for airtight sealing of an opening of a bag for medical purposes with a bag contour welding unit, to a method of filling a bag with a device that has a filling needle, the bag being manufactured with a bag contour welding tool, to a method of manufacturing a bag with a bag contour welding tool, to a plant for manufacturing and filling a bag, the bag being manufactured with a bag contour welding unit, and to a bag which is manufactured and filled with this plant. The invention allows a filling of a bag, in particular a bag for medical purposes, without the necessity of providing a filling port on the bag. In this way, resources and costs can be saved, preventing damage to the environment.

An inline packaging machine for automatically accommodating and filling different sized containers, such as pouches, to reduce changeover time and thereby improve operating efficiency of the machine. The machine includes stations disposed longitudinally along a center line of the machine, including a first carrier track opposing a second carrier track with respect to the center line. A first clamp is disposed on the first carrier track and at least a second clamp is disposed on the second carrier track wherein the clamps are configured to releasably secure first-sized pouches for filling. The pouches are advanced inline from a setup station through an opening station to a filling station for filling with contents. The filled pouches are then advanced to a sealing and discharging station. A control system automatically adjusts the distance between the corresponding clamps to accommodate second-sized and/or third-sized pouches for inline processing and filling.
