A process for producing a laminate, which comprises a preliminary heating step of heating, while conveying by a metal roll 33 for heating and a metal roll 32 for thermal lamination without pressing in the thickness direction, a temporary laminate wherein heat resistant resin films 2 and 2 are laminated on both surfaces of a fluorinated resin film 1 containing a melt-moldable fluorinated resin (A) having at least one type of functional groups selected from the group consisting of a carbonyl group-containing group, a hydroxyl group, an epoxy group and an isocyanate group and after the preliminary heating step, a thermal lamination step of pressing the temporary laminate in the thickness direction, while heating it by metal rolls 31 and 32 for thermal lamination at a thermal lamination temperature of at least the melting point of the fluorinated resin (A) ant at most 420 C., for bonding.

A device of adjusting registration of plastic flooring contains a rolling unit and an adjusting unit. The rolling unit includes a press roller set having a first press roller, a second press roller, a third press roller, and a fourth press roller. The rolling unit delivers a substrate, a printing layer, and an anti-abrasion layer to the press roller set so as to be pressed together by the third and fourth press rollers. The printing layer has a pattern area, and the third press roller has a pressing pattern section. A first end of each of the third and fourth press rollers is connected on a fixed segment, a second end of each of the third and fourth press rollers is connected on a movable segment, and the adjusting unit is fixed outside the movable segment. The adjusting unit includes at least one power source and a movable rod.

Deformed web materials are disclosed. The web materials have discrete deformations formed therein. The deformations may be features in the form of portions of a web with apertures therein, protrusions, depressed areas, and combinations thereof. These features may extend out from the surface on one side of the web, or from both of the surfaces of the web. Different features may be intermixed with one another.

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.

A pinched sack, which is made at least partially from a plastic material in the form of a tube section, has at least one pinched bottom at one end of the tube section. At least some of the plastic material is stretched, and at least one pinched bottom is provided by a thermally induced bonding process.

Methods and apparatuses for bonding polymeric parts are disclosed. Specifically, in one embodiment, the polymeric parts are bonded by plastically deforming them against each other while they are below the glass transition temperatures.

A joining method for connecting at least two thermoplastic workpieces is provided to permit the joining even of non-transparent carbon fiber reinforced plastics parts by means of laser welding, in which a splice is produced at the edge regions of the workpieces and the workpieces are subsequently positioned relative to one another in such a manner that the opposite splice regions bound a seam region. Connecting bodies are then inserted into the seam region and heated by means of local heat input by laser beam such that a fixed integrally bonded connection forms between the workpieces and the connecting bodies.

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.

A glass and polymer film assembly including a glass film and a polymer film bonded to a surface of the glass film. The polymer film is directly bonded to the glass film by applying the polymer to the glass film when the glass film is above a bonding temperature of the polymer film. The glass film may have a thickness less than about 1 mm and the polymer film may be an oriented semicrystalline homopolymer which is permanently bonded to a major surface of the glass film.

Various embodiments relate to plastic-metal junctions and methods of making the same via laser-assisted joining. The present invention provides a method of forming a junction between a metal form and a solid plastic. The method can include laser treating a surface of a metal form to generate a feature (e.g., a plurality of at least one of pores and grooves) in the surface of the metal, wherein the laser has an angle of incidence with the surface of the metal of other than 0 degrees. The method can include contacting the metal surface including the feature with a flowable resin composition. The method can include curing the flowable resin composition to form the solid plastic, to provide the junction between the metal form and the solid plastic.
