A fluid impervious stitching method for a seam of a vapor-permeable virus-barrier laminate. The laminate comprises: at least one thermoplastic resin fiber layer; at least one vapor-permeable virus-barrier thermoplastic elastomer film layer; and a bonding layer located between the two layers and formed of an adhesive capable of being fused with the two layers. In the stitching method, overlapping or stacking is performed to form a seam, and heat sealing is performed on the laminate at the seam. The temperature of heat sealing is higher than the melting point of a material layer having the highest melting point in the laminate, but lower than the temperature at which perforation or decomposition occurs in any material layer in the laminate. The heat-stitched seam has excellent windproof, vapor-permeable, virus barrier and liquid-barrier performance, has a smooth appearance without wrinkles, and feels soft. Also provided is a protective textile product prepared by means of the stitching method.

The pressure element comprises a fitting portion configured to be fitted to the countersealing member and a contact portion defining a contact surface facing, in use, the sealing member and configured to interact with a sealing element of the sealing member to press and seal the tube therebetween. The pressure element comprises at least one engagement element configured to cooperate with a complementary engagement element carried by the countersealing member to guide the pressure element according to a predetermined orientation during fitting of the pressure element to the countersealing member.

An apparatus for vacuumizing and sealing a package includes a plurality of platens and vacuum chambers, each chamber adapted to mate with a dedicated one of the platens; a conveying system for conveying the platens and chambers along a generally angular path having a single axis of rotation; an automated loading assembly having a linear component and configured to load a package onto each of the platens; an automated unloading assembly having a linear portion and configured to unload a vacuumized, sealed package from each loaded platen onto an outfeed conveyor; and a vacuumizing/sealing system configured to cause relative movement of each chamber/platen pair, along a portion of the angular path, to form therebetween an air-tight enclosure accommodating the package and effect vacuumization and sealing of the package.

The invention relates to a welding method for material webs which each consists of a multilayer composite having a barrier layer and are connected to each other via a sealing seam. In order to provide a welding method by means of which sealing seams can be produced which, on the one hand, meet the highest demands on strength and, on the other hand, prevent light, in particular UV light, from penetrating into the product to be packaged, according to the invention, the sealing seems are produced by leading two sealing surfaces of two tools together, wherein the material webs are arranged between the sealing surfaces and the sealing seam is produced having two seams lying beside each other, a main seam and a secondary seam and, during the production of the main seam, the two sealing surfaces exert a main welding pressure on the material webs and, during the production of the secondary seam, the two sealing surfaces exert a secondary welding pressure on the material webs, wherein the secondary welding pressure is lower than the main welding pressure, at least in some sections, and, in the secondary processing step, at least one of the two sealing surfaces is structured.

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.

Embodiments are directed to a removable cap with a top hole and a seal with a heat induction closure for sealing an opening of a container. Advantageously, the cap and the seal do not need to be removed for a probe to access contents of the container, when used in a diagnostic analyzer, thereby eliminating operator steps of cap removal and seal peeling/perforation. Automated opening of the cap and seal combination is provided by puncturing the seal. The seal retains its opened shape required for unobstructed, non-contact probe access to contents of the container. The seal is comprised of three layers: a first polymer sealing layer capable of being heat-sealed to a container; an aluminum foil layer on top of the first polymer sealing layer, configured to heat seal the first layer by inductive heating; and a second polymer layer on top of the aluminum foil layer for protection.

A method for handling containers (I) of collapsible type in a filling machine (20) comprising consecutively arranged stations (S1, S2, S3, S4, S5, S6) comprising a filling station (S3) and a gas filling station (S5), the method comprising intermittently moving the containers (I) to the consecutively arranged stations (S1, S2, S3, S4, S5, S6), supplying, at the filling station (S3), liquid product into the product compartment (5) and supplying, at the gas filling station (S5), gas into the handle compartment (7). The filling station (S3) and the gas filling station (S5) are operated such that liquid product is supplied to the product compartment (5) of one of the containers (I) while gas is supplied to the handle compartment (7) of another of the containers (I). The step of supplying gas at the gas filling station (S5) comprises providing a first gas flow (Qi) at a first pressure (Pi) and delivering said first gas flow (Qi) from the nozzle (30) to the handle compartment (7) via said inlet (11), and subsequently providing a second gas flow (Q.sub.2) at a second pressure (P.sub.2), lower than said first pressure (P.sub.1), and delivering said second gas flow (Q.sub.2) from the nozzle (30) to the handle compartment (7) via said inlet (11) for establishing a target pressure (P.sub.T) inside said handle compartment (7) corresponding to said second pressure (P.sub.2).

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.

A battery cell manufacturing device according to one embodiment of the present disclosure includes a sealing tool that presses a sealing part, in a battery case including a sealing part having a structure in which an electrode assembly is mounted onto a receiving part, and an outer peripheral surface is sealed by heat fusion, wherein the sealing tool comprises a first sealing tool located at an upper part and a second sealing tool located at a lower part with respect to the battery case, and wherein the sealing tool comprises a sealing surface in contact with the sealing part, and at least one pressure sensor is located on the sealing surface.
