The two clamping shoe pairs (42, 44) of the clamp (36, 38) are moved apart from one another during the sealing process.

The present invention relates to a method and to a system for calibrating an automatic pouch forming machine.

The present invention also relates to a device for characterizing a pouch precursor made of flexible heat-sealable film, said device comprising: a punch; a heat source for heating at least a tip of the punch to a given temperature; an actuator for pressing the punch against the pouch precursor made of heat-sealable film, with a given pressure; a measurement device for measuring the penetration of the punch in the pouch precursor, under the given conditions of temperature and pressure.

The disclosure relates to a cash bag sealing device for retaining and sealing a cash bag into which cash can be deposited and stored, wherein said cash bag sealing device having a supporting structure onto which two sealing jaws are oppositely arranged and of which at least one is reciprocally moveable between a sealing position and an open position and wherein at least one sealing jaw includes a heating element, the cash bag sealing device being configured to form a seal in the cash bag by the reciprocally moveable sealing jaw pressing the cash bag against the other sealing jaw in the sealing position and by heating said heating element, and wherein at least one of the sealing jaws includes at least one cash bag fastener.

The invention relates to an automatic pressing power device of a vacuum packaging machine, wherein the automatic pressing power device comprises main body, power plate and power airbag, wherein the power plate is connected with the main body through the power airbag and forms a telescopic closed cavity; the bottom of the main body is provided with an air nozzle communicated with the closed cavity. The automatic pressing power device provided by the invention does not need to tighten the upper cover artificially, and has the characteristics of simple structure, low cost, high structural stability, long service life and the like.

A sealing patch for a polymeric bag includes a carrier, a pressure sensitive adhesive on the carrier and a heat-activated material on the pressure sensitive adhesive. A high-strength polymeric bag is formed from woven tapes and is coated with a polymer material. The sealing patch is positioned on the bag for sealing the bag. A method for sealing a high-strength polymeric bag with a sealing patch and a device for sealing a polymeric bag with a sealing patch are disclosed.

An intelligent trash can includes a closing and packing mechanism for automatic closing of a garbage bag. The closing and packing mechanism include a pair of first pressing rods and a second pressing rod. The pair of first pressing rods are configured for being synchronously approached or synchronously moved away under the driving of a first belt transmission unit. The second pressing rod is perpendicular to the pair of first pressing rods. The second pressing rod is configured to perform linear reciprocating motion along a length direction of the pair of first pressing rods under the driving of the second belt transmission unit.

An ice bagging assembly and related method with a horizontal ice bag cassette, a pair of opposing ice bag ply graspers configured to move an empty ice bag from the horizontal ice bag cassette to a vertical position to receive cubed ice before it is sealed shut and dropped to an ice bag merchandiser. The opposing graspers may be configured as rotating wheels and may have a grasping sensor. The ice bag cassette may be slidably and tiltably supported for easy replacement of horizontal bags. A load sensor, optical or mechanical, may be associated with the ice hopper to sense how much ice has been put in each bag. A pair of angled guides may guide a hopper into a support frame for the system.

A horn and an anvil are moved toward and away from each other by axially reciprocating a driving rod and thereby reciprocatingly rotating a forked lever in a predetermined angle range. The horn and the anvil are moved toward and pressed against each other with a predetermined force with a bag mouth b held therebetween. A sensor detects the position of a second mounting block secured to the rear end of a sliding shaft of the anvil, thereby detecting the distance between respective pressing surfaces of the horn and the anvil, i.e. the thickness m of a portion of the bag mouth held between the pressing surfaces. When the thickness m is not less than a predetermined threshold value M, a vibrator is activated to perform sealing. When the thickness m is less than the threshold value M, no sealing is performed.

A vertical bag-making/filling/packaging machine (1) comprises: a film supplying portion (5) which lets out a film (F) from a roll (Fr); a bag-making guide (31) which folds the film (F) into a tubular shape and changes a conveying direction downward; a vertical sealing portion (60) which thermally seals side edges of the film (F) to each other in an up-down direction so as to make the film into a tubular shape; a film conveying portion (50) which conveys the film (F) downward; a filling portion (70) which loads a content (X) into an interior of the film (F); a lateral sealing portion (80) which thermally seals the film (F) in a left-right direction so as to make a bag body; a square-bottom sealing portion (90) which expands a bottom of the bag body to a rectangular shape from an inside and then thermally seals the bottom to form a rectangular bottom surface; and a cutter (89) which cuts off the bag body from the film (F).

The invention relates to a device for welding a connection region of a film to a connection part having an axial direction. In the case of conventional devices, there is the risk of steep workpiece edges causing uncontrolled weak spots in the film and in the weld seam. According to the invention, the film is extended in a controlled manner such that the film has a length reserve. The film is extended in such a way that the film has a deformation cross-section that runs out such that the deformation is not visible on the final product. In this connection, the invention further relates to a use of a film, to a method for welding, to a method for producing bags, to a system for producing bags, and to a bag.
