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 method of joining first and second layers of material according to the principles of the present disclosure includes applying a layer of adhesive between the first and second layers and allowing the adhesive layer to at least partially cure. The method further includes piercing the first layer with a headless end of a rivet after the adhesive layer is cured, deforming the second layer with the headless end of the rivet, and bending the headless end of the rivet radially outward.

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.

An apparatus and method for joining pipes includes a plate for melting mating surfaces of the pipes to be joined. Additionally, the apparatus utilizes a vacuum in order to push the first and second pipes together in lieu of hand or mechanical pressure which may be inconsistent. Additionally, the vacuum allows the pipes to be joined to settle on each other in order to create a pressure about a periphery of the end of the pipe being joined to the other pipe. The consistent pressure creates a very strong joint between the first and second pipes.

There is described a unit for applying at least one pre-formed opening device onto a hole of a web of a packaging material, unit comprises an advancing means device for advancing the web along a path; and at least one application station, which is fed, in use, with pre-formed opening device and seals, in use, pre-formed opening device on the hole of web.

A method and apparatus for pleating or otherwise shaping a web are described herein. The method and apparatus may have numerous applications. In some embodiments, the method and apparatus are used in the formation, filling, and sealing of unit dose packages for consumer products. A method and apparatus for forming sealing two moving webs together, which webs have portions that are non-planar are also described herein.

A device for preparation of double fabric for down products comprises a printing means that can print an adhesive in a predetermined printing pattern on fabric; a drying means that can dry or fix the adhesive; a laminating means that can stack and laminate the fabrics on which an adhesive is printed; and a bonding means that can bond the fabrics with a cured adhesive by pressing with a predetermined pressing means and high-frequency heating to cure the adhesive; wherein said printing pattern and the pressing pattern are the same in pattern (shape), can be overlapped on the basis of the center line and have a difference in size (width) of 20% or less. Consequently, double fabric for down products thus manufactured has an excellent adhesiveness and durability and an aesthetically excellent pattern line with good clearness and finishing quality.

A process of manufacturing a down product comprises at least one bonding pattern line for the compartment separation without forming sewing holes by printing and drying a heat-reactive adhesive on the inner surface of an inner fabric, an optional mesh material and/or an outer fabric in a predetermined pattern, laminating said inner fabric, optional mesh material and/or outer fabric, and then high-frequency heating them under pressing with a pressing pattern the same as the printing pattern to bond the inner fabric, optional mesh material and outer fabric. Accordingly, it is possible to manufacture a down product having a bonding pattern line composed of a bonding line with excellent adhesiveness and durability and an aesthetically excellent pattern line with good clearness and finishing quality as well as to achieve a mass production of down products by mechanization and automation.

The present invention is intended to prevent cutting of the resilient and elastic members by a welding process. The foregoing issue is solved by passing a first sheet layer, a second sheet layer, and elongated resilient and elastic members continuously disposed in an MD direction between the two sheet layers, between a first roll with joint convex parts provided at circumferential intervals on an outer peripheral surface and a second roll opposed to the first roll, and pressurizing and heating the first sheet layer and the second sheet layer to form sheet joined sections by welding the first sheet layer and the second sheet layer in such a manner as to cross the resilient and elastic members and have MD-direction intervals therebetween, wherein circumferentially continuous grooves are formed on a pressurization surface of the second roll, passage sections of the resilient and elastic members are pressurized and heated in positions including the grooves of the second roll, and non-passage sections of the resilient and elastic members are pressurized and heated in positions not including the grooves of the second roll.
