Chemical barrier fabric

A chemical barrier fabric and a method of manufacturing the fabric is provided. The chemical barrier fabric includes at least first and second chemical barrier layers which have an interfacial region therebetween and which are intermittently point bonded providing a point-bonded area which is in the minority and an un-bonded area which is in the majority in the interfacial region. The chemical barrier layers typically comprise single layer polymer films and/or co-extruded layers. A non-woven layer may also be point-bonded to either the first or the second chemical barrier layer to give support to the fabric.

Method and device for thermal activation of packaging sleeves

A method and device for thermal activation of tube-shaped packaging sleeves made of cardboard/plastic composite material, wherein a hot gas is applied to the tube-shaped packaging sleeve by a heating device in order to produce the base or the head of the packaging. To achieve even heating for the activation of the contact surfaces with production using simple construction, wherein the energy required for the activation process is used as completely as possible for the heating of the surfaces to be activated, the heating device is placed into effective contact with the surfaces to be activated by the heating device being moved inside the tube-shaped packaging sleeves for activation. The heating device has at least one nozzle element with an outlet opening, the external shape of which nozzle element corresponds to the internal shape of the end of the tube-shaped packaging sleeve to be activated.

PIPE LINER AND METHOD OF MAKING AND INSTALLING THE SAME

An eversion liner for lining a pipe includes an impermeable outer portion, inner and outer strength portions inside the impermeable outer portion, and a middle portion including at least one felt layer radially between the inner and outer strength portions. At least one of the inner and outer strength portions is formed from a unitary sheet of strength material that includes parallel chopped strands of fiber. The longitudinal edge margins of the sheet of strength material are positioned in overlapping engagement and joined together by joining structure. The parallel chopped fibers can be oriented transverse to the length of the liner. The joining structure can prevent reduction in a width of the overlapped edge margins as the liner expands during eversion.

Method of manufacturing contoured objects by radio frequency welding and tooling assembly for same
10773462 · 2020-09-15 · ·

A method includes compressing a non-dielectric, elastically-deformable component, a wire mesh component, and a dielectric, contoured object between first and second forming tools. Once the components are compressed, radio frequency energy is supplied to the first forming tool, thereby causing a radio frequency electromagnetic field to be generated between the first forming tool and the wire mesh component that results in a contoured weld of the contoured object. A tooling assembly is configured to carry out the method.

LID FOR A METAL CAN, COMPRISING A METAL RING AND A PEELABLE, HEAT-SEALED MEMBRANE
20200276631 · 2020-09-03 ·

Disclosed is a lid suitable for closing a metal can, the lid including a metal ring onto which a peelable membrane is sealed. An inner annular part of the metal ring is equipped with a roll defining an annular space therebetween. The first connection portion of the roll and the second connection portion of the inner annular part opposite are sealed to one another by element of a heat-sealing material to form a seal sealing the annular space so at to protect the free edge of the roll. The invention also relates to a method for producing such a lid.

INSULATED CONTAINER

A container is formed to include and interior region that is configured to receive a product therein and the container is insulated.

A METHOD AND AN APPARATUS FOR APPLYING A SEALING STRIP TO A WEB OF PACKAGING MATERIAL

A method of applying a sealing strip onto a web of packaging material comprising advancing the web along a web advancement path; applying a first longitudinal portion of the sealing strip onto a longitudinal edge of the web, sealing the first longitudinal portion of the sealing strip onto the longitudinal edge, detecting and/or determining a correct alignment of the sealing strip with respect to the web. The detecting and/or determining of the correct alignment comprises acquiring an image of a second longitudinal portion of the sealing strip and a reference marker of a strip application apparatus, analyzing the acquired image to determine at least a first transversal distance between the reference marker and a longitudinal border of the second longitudinal portion; and evaluating the correct alignment/misalignment as a function of at least the first transversal distance.
