A welding unit for a machine for forming capsules having a pleated capsule body and a reinforcing element. The welding unit has a welding housing configured to accommodate the reinforcing element and the pleated capsule body coaxially during welding. The welder, preferably with fixed geometry, is coaxial with respect to the welding housing and configured to be inserted within the welding housing and to weld the reinforcing element to the pleated capsule body. The welding housing acts as a counter element for the welder during welding. The welding unit has elastic means coupled to the welding housing in such a way that said welding housing is elastically movable and/or elastically deformable by the thrust of the welder.

A method for manufacturing an underlay material (8) to be set under parquet or a laminate, the underlay material including a sheet material layer (1) and a flexible cellular plastic material layer (3) bonded under the sheet material layer, and a bottom surface of the cellular plastic layer being processed for providing an air space, whereby the bottom surface of the cellular plastic material layer (3) is processed by melting the cellular plastic material locally for providing an air space (9) and for simultaneously bonding the cellular plastic material layer to the sheet material layer (1). An underlay material manufactured by such a method is also described.

A method for making labels comprising providing a plastic substrate layer and a paper substrate layer. The paper substrate layer comprises a printed display information sheet, wherein the printed display information sheet comprises a plurality of display information tags arranged in an array. The plastic substrate layer is coupled to each of the rows of display information tags within a first portion of the display information tags to form a composite substrate row. A first line of perforations is cut into a width of the composite substrate at one or more first spaced intervals, a length of the first spaced intervals being defined by a length of the display information tags. A a second line of perforations is cut into a width of the composite substrate at one or more second spaced intervals, a length of the second spaced intervals being defined by a height of the display information tags.

A method of fastening an edge structure to a construction element includes providing the construction element, being a planar structure with two cover regions and a middle region between the cover regions; providing the edge structure being continuously extended, the edge structure having contact surfaces with a thermoplastic material shaped to lie against the cover regions in an outer surface of the construction element, and, opposite the contact surfaces, a coupling-in surface for coupling energy into the edge structure; coupling energy into the edge structure and pressing the contact surfaces against the cover regions until at least a portion of the thermoplastic material is liquefied and pressed into the cover regions; and repeating or continuing the steps of coupling and pressing until the edge structure is attached to the building element at a plurality of discrete locations or over an extended region along an edge of the construction element.

A method for adhering polylactic acid-based (such as expandable polylactic acid resin (PLA) foam) custom product packaging to a surface is provided. The surface is heated to a suitable temperature and the PLA foam may be pressed against the surface for a second or seconds to rapidly adhere the PLA foam to the surface. The adhesion between the surface and the PLA foam may be sufficient to maintain the adhesion, but may also allow for the PLA foam to be removed from the surface.

A method for adhering polylactic acid-based (such as polylactic acid resin (PLA) foam) custom product packaging to a corrugate surface is provided. The corrugate surface is heated to a suitable temperature and the PLA foam may be pressed against the corrugate surface for a second or seconds to rapidly adhere the PLA foam to the corrugate surface. The adhesion between the corrugate surface and the PLA foam may be sufficient to maintain the adhesion, but may also allow for the PLA foam to be removed from the corrugate surface.

A packaging device includes a resin film, a covering device, and a heating device. The film includes a welding portion containing a hot melt adhesive and is capable of being welded to a portion to be welded. The covering device covers, with the film, at least a part of a packaging object placed on a base formed of corrugated cardboard and at least a part of the base. The heating device heats a contact portion with the base in a state in which the welding portion of the film is in contact with the base. When heat is added by pressing the welding portion against the base, the hot melt adhesive in the welding portion melts and bonds the corrugated cardboard and the film. Polar functional groups introduced into the surface layer of the film are mixed and combined with the functional groups contained in a fiber of the base.

The present invention relates to a method for providing a product viewing window in a container. The container has at least a body ply and a liner ply, wherein the body ply has at least one aperture therethrough. The liner ply is adhered to the inner surface of the body ply and has a portion extending across the aperture, forming a window into the container. The method involves providing a window-finishing machine that comprises at least two platens and, optionally, a machine pocket positioned between them, a heating element extending through at least one of the platens, and a pressurized air device that is adapted to release pressurized air into the container through at least one of the platens. The container is engaged between the platens in an airtight manner and, optionally, the container window is positioned adjacent the inside wall of the machine pocket. The heating element heats the window of the container to the desired temperature, pressurized air is injected into the container such that the window is forced at least partially through the aperture of the container (and optionally into contact with the machine pocket wall), and the container window is then cooled to the desired temperature.

A method for joining two objects by anchoring an insert portion provided on one of the objects in an opening provided on the other one of the objects. The anchorage is achieved by liquefaction of a thermoplastic material and interpenetration of the liquefied material and a penetrable material, the two materials being arranged on opposite surfaces of the insert portion and the wall of the opening. Before such liquefaction and interpenetration, an interference fit is established in which such opposite surfaces are pressed against each other, and, for the anchoring, mechanical vibration energy and possibly a shearing force are applied, wherein the shearing force puts a shear stress on the interference fit.
