A sealing apparatus 200 for sealing together two film portions 202, 204 may include a heating element 206 positioned in relation to a pair of nip pressure devices 208, 210 for creating a seal 311 between the two film portions 202, 204 and trimming the two film portions 202, 204 at the created seal. A controller 214 is connected to the heating element 206 and is for connection to a power source for applying a variable amount of power to the heating element 206. The amount of power varies based on at least a speed of the two film portions 202, 204 passing the heating element 206.

[PROBLEM TO BE SOLVED]

To provide a method for readily forming an easily separable portion having an adhesive strength that is required as a package bag on packaging film, a package bag having an easily separable portion formed by this method, and a filling-packing machine utilizing this method.

[SOLUTION]

A method forming an easily separable portion in packaging film by interposing at least two packaging films between a horn emitting ultrasonic waves and an anvil oppositely disposed to the horn, and vibrating the packaging films by the ultrasonic waves, in which a vibratable layer is provided on the packaging film in at least one of the horn side and the anvil side.

A thermoplastic product includes a fabric-based reinforcing sheet and a polymerized thermoplastic material. The fabric-based reinforcing sheet is wound about a mandrel to form a plurality of layers having a cross-sectional shape that corresponds to the mandrel. The fabric-based reinforcing sheet includes a plurality of fiber bundles, which may have a bidirectional orientation or configuration. A polymerized thermoplastic material is disposed within each layer of the fabric-based reinforcing sheet. The polymerized thermoplastic material bonds each layer of the fabric-based reinforcing sheet to an adjacent layer.

The invention relates to a method for producing flexible tube bodies (18) for packaging tubes from a film substrate (1) which has a print, preferably on an outer side (2), and which has or consists of at least one weldable plastic layer and which comprises a first longitudinal edge side (8), which extends in a longitudinal direction, and a second longitudinal edge side (8′) parallel thereto and spaced apart therefrom, wherein the film substrate (1) is shaped by shaping means (23) to form a tube, and the two longitudinal edge sides (8, 8′) are in particular welded to one another with the formation of a longitudinal weld seam, wherein a strip (12) is arranged, in the region of the abutment point and/or of the longitudinal weld seam, in the interior (17) of the film substrate (1) shaped to form the tube and is connected, in particular welded, to the longitudinal edge sides (8, 8′) at least in certain regions or portions. According to the invention, prior to the formation of the longitudinal weld seam, at least one longitudinal edge side (8′) is shaped, in particular cut, in such a way that, in the film substrate (1) shaped to form the tube, the longitudinal edge sides (8, 8′) bear against one another, in particular in abutting fashion, radially only in the region of the outer side (2) with at least one tip (9) formed by the shaping operation.

The present disclosure is directed to a compression belt for inflation and sealing devices. The device may include an inflation assembly, a heating assembly, and a drive mechanism. The inflation assembly may direct fluid between first and second overlapping plies of a flexible web material to inflate chambers between the plies. The heating assembly may be operable to heat the first and second plies of the web material to create a longitudinal heat seal that seals the fluid in the inflated chambers. The drive mechanism may drive the web material in a downstream direction. The drive mechanism may tension the web material against the heating assembly. The drive mechanism may include a first belt including a high grip material on a surface that contacts the web material to grip the web material during heating by the heating assembly.

The present invention relates to a package seal control system (300), comprising a control unit (308), and data recording means (306) adapted to be communicatively connected to the control unit, wherein said data recording means (306) is adapted to monitor a longitudinal seal (302) extending in a direction conforming to a direction of flow of a packaging material (e.g. Tetra Pak) in a packaging and filling machine (100). The present invention further relates to its use and method for monitoring and optionally controlling the longitudinal seal (302) of a package material in a packaging and filling machine (100).

Disclosed herein is a packaging machine that according to one embodiment includes a rollers block with a plurality of roller assemblies distributed in series along a horizontal longitudinal axis of the machine and a transmission block with a motor and a transmission mechanism configured for transmitting the rotation of the motor to all the roller assemblies. At least one roller assembly is independent of the rest of the roller assemblies, is movable with respect to the transmission block, and is configured for cooperating with the transmission mechanism in an operative position, in which the transmission mechanism transmits the rotation of the motor of the transmission block to the roller assembly.

An ultrasonic welding system. The system includes an ultrasonic transducer assembly having a horn and a first transducer and a second transducer arranged to impart ultrasonic energy into the horn. The horn has a first part-interfacing surface and a second part-interfacing surface opposite the first part-interfacing surface. An actuator assembly is operatively coupled to the ultrasonic transducer assembly and configured to cause rotation of the horn. A controller is configured to: cause the actuator assembly to rotate the horn so that the first part-interfacing surface applies the ultrasonic energy to a first part along an entire length of the first part-interface surface while a first ultrasonic energy is applied through the horn via the first transducer to cause the first part-interfacing surface to vibrate back and forth along its entire length as the first ultrasonic energy is applied by the first transducer to the horn.

The invention concerns a composite film for receptacles, in particular for tubes, with a plurality of layers connected to one another in a sheetlike manner to form a layer stack, this composite film comprising: a base film 1 having a lower surface 8 and an upper surface 10; a cover film 2 having a lower surface 11 facing the base film 1 and an upper surface 12; an ink layer 7 applied on the upper surface 12 of the cover film 2, excepted on a first lateral edge margin M1 of the composite film.

The composite film comprises an ink line 13 applied between the base film 1 and the cover film 2, in said first lateral edge margin M1 region, along the whole length of the composite film.
