A fill packaging machine includes a vertical sealing means for folding a packaging film at its central part and continuously forming a vertical sealed portion at its side edge part to shape into a cylinder, and a lateral sealing means for forming lateral sealed portions in a direction perpendicular to the longitudinal direction of the packaging film. An easy separable sealed portion is continuously formed in the side edge part of the packaging film by the first vertical sealed portion forming section, and a vertical sealed portion having a partial non-sealed portion of a bottle mouth type is formed on the easy separable sealed portion by the second vertical sealed portion forming section. The first vertical sealed portion forming section is a pair of heat sealing rolls or heat sealing plates, a surface of at least one of which is made from an elastic material softer than a metal.

A support device for a tubular element, includes a housing part configured to house, during use, the tubular element, and at least a mobile part for guiding and positioning the tubular element and for protecting the housing part. The mobile part is configured to assume at least a first position to access the housing part of the tubular element, in order to easily insert the tubular element into the housing part, and to assume at least a second position to retain the tubular element and to at least partly cover said housing part and the tubular element positioned therein. The mobile part includes a lever for passage from the first position to the second position and drivable by the tubular element during its insertion into the housing part.

An ultrasonic module for use in package sealing systems that includes a moveable front jaw; an elognated sonotrode disposed within the front jaw, wherein the sonotrode includes an elongated sealing face, and wherein the width of the sealing face is at least 12 inches (30.48 cm); a moveable rear jaw; and an anvil mounted on the rear jaw opposite the sonotrode, wherein the anvil mechanically cooperates with the sonotrode to seal a package.

A sonotrode that includes a sealing face; a front quarter wavelength region adjacent to the sealing face, wherein the front quarter wavelength region has been modified to increase the gain of the sonotrode; and a rear quarter wavelength region adjacent to the front quarter wavelength region, wherein the rear quarter wavelength region has been modified to create a non-uniform amplitude profile across the length of the sealing face of the sonotrode.

A vertical form fill and seal system supports a sheet of material having material segments and a tube sized for drawing edges of the elongated sheet of material together in an overlapping configuration to form the sheet into a substantially tube shape. The VFFS also includes a sealer that seals the edges of the material to one another and a gusseting mechanism sized for forming a gusseted tuck in each of a left panel portion of the material and a right panel portion of the material. A cutting mechanism removes a first portion and a second portion of a first segment of the material segments in order to form a first cut and a second cut in the first segment and a sealing mechanism folds and seals the first segment at the first cut and at the second cut to provide an end wall with a substantially flat, rectangular-shaped footprint.

There is provided a frame for a horizontal flow-pack packaging machine utilizing a center folded or side sealing machine with twin reel or reel feed form below, suitable for packaging a food product or a non-food product with heat sealable or cold weldable plastic film wound on a reel. The frame is provided with two cantilevered supports arranged one above the other in parallel, the lower support supports the operating mechanical components of the packaging machine and the upper support supports the control group and the pneumatic system of the packaging machine.

The present disclosure provides an apparatus for forming a stream of individual packets, comprising a folder arranged to form a tubular web structure, a feeder arranged to feed the formed tubular web structure to a nip; a first rotor comprising a first sealing jaw and a knife, a second rotor comprising a second sealing jaw and an anvil, the sealing jaws, the knife and anvil rotating into opposing relation at the nip so as to form a severed, completed packet beyond the nip. The apparatus includes an open ended packet catcher adjacent the first and second rotors, which is arranged to catch the severed, completed packets beyond the nip whereby a stream of packets is established. The packet catcher includes a stripper disposed in a proximal location to at least one of the anvil, the knife and the sealing jaws when the anvil, the knife and/or the sealing jaws are rotated beyond the nip, whereby, should a completed packet stick to any of the anvil, the knife and/or the sealing jaws, the stripper is operative to free the stuck packet from the anvil, the knife and/or the sealing jaw. The present disclosure provides a fin sealer and method to seal a radially outwardly directed fin of a tubular web structure by directing the fin through a nip between a first and a second fin sealing rollers while communicating heat to the fin through at least one of the fin sealing rollers, the fin sealer being further arranged to maintain a nominal face-to-face relation between an outer annulus of the first fin sealing roller and an outer annulus of the second fin sealing roller with a flexible connection between a hub element of the second fin sealing roller with the outer annulus of the second fin sealing roller. A cooling system is also provided, which is operative upon one of the rotors of a cut and seal station.

The invention relates to a sealing body, where heat-producing elements of a heating element are contacted from the rear side thereof. Other aspects relate to a sealing body where the site of the heat production and the site of the heat dissipation (i.e. the point of action) are as close to each other as possible. Other aspects relate to a sealing body comprising a heat element with a built-in temperature sensor. Other aspects relate to a sealing body with a defined sealing contour. Other aspects relate to a sealing body having a three-dimensionally structured contact surface. Other aspects relate to a sealing body with a circular, annular, or strip-type heat element. Other aspects relate to a sealing body with built-in electronic circuits. Other aspects relate to a sealing body that can cool the heating element as required. Other aspects relate to a sealing body that can suck up the material to be welded.

The present invention relates to a sealing band for a sealing jaw arrangement, comprising a contact surface and an opposite bottom surface, a first portion adjacent to the contact surface and a second portion adjacent to the bottom surface. The portions are separated by a waist, and said sealing band is symmetrical along a first axis that extends perpendicularly from a middle of the bottom surface, and the waist between the first portion and the second portion is located closer to the contact surface than to the bottom surface. The invention also relates to a counter jaw for holding the sealing band, and to a sealing jaw arrangement comprising such a counter jaw and a heating jaw.

A method and apparatus for pleating or otherwise shaping a web are described herein. The method and apparatus may have numerous applications.
