A panel may be formed with mandrels inside of stiffening members. The panel may be coupled to a panel holding jig. A winch may be coupled to the mandrels. The winch may pull the mandrels out of the stiffening members and into curved tracks.

The invention relates to a method for producing a component bond (70, 140) comprising: a fastening structure (60, 160) that has at least one component layer (60; 160a, 160b); and a thermoplastic connecting element (10, 110) having a head (12) and a shank (14), in which method the connecting element (10, 110) is driven into the fastening structure (60, 160) under pressure whilst rotating, such that the shank (14) penetrates the fastening structure (60, 160). The connecting element (10, 110), after penetrating the fastening structure (60, 160), is converted by friction into a softened, free-flowing state in a die (44, 144) which is placed against the fastening structure (60, 160) in the opposite direction to the driving direction, resulting in a thicker section (22, 22) that extends beyond the radial extent of some sections of the shank (14). The fastening structure (60, 160) is thus interlockingly held between the head (12) and the thicker section (22, 122).

A method for producing a tube skirt for a flexible tube, said tube skirt being manufactured from a flat strip 1 comprising a decorative film 15 superimposed on a primary film 16, said primary film 16 comprising a sealable inner layer 14 at the lower surface 20 of the strip 1 as well as two stabilizing layers 11, 13, said decorative film 15 comprising a sealable outer layer 7 at the upper surface 19 of the strip 1, and a decorative layer 8, 9. This method comprises the following steps: winding the flat strip 1 into the form of a sleeve to shape the tube skirt; superimposing a first side border 2 of the strip 1 on a second side border 2 of the strip 1 to form an overlapping area 3, the sealable inner layer 14 of the primary film 16 of the first side border 2 overlapping the sealable outer layer 7 of the decorative film 15 of the second side border 2; applying a heating temperature T2 to the inside of the tube skirt at the inner face 22 of the overlapping area 3 to produce the side weld of the tube skirt; simultaneously with the application of the heating temperature T2, applying compression between the outer 21 and inner 22 faces of the overlapping area 3 so as to finalize the side weld of the tube skirt.

A panel may be formed with mandrels inside of stiffening members. The panel may be coupled to a panel holding jig. A winch may be coupled to the mandrels. The winch may pull the mandrels out of the stiffening members and into curved tracks.

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.

The present disclosure relates to a method for producing an oral pouched snuff product comprising a filling material (29, 10) and a saliva-permeable pouch (43) enclosing the filling material (29, 10), the product (29, 10) having a moisture content of at most 20% by weight, in particular at most 10% by weight, based on total weight of the product (29, 10), the saliva-permeable pouch (43) having one or more seals (45, 46), and said filling material (29, 10) comprising at least 20% by weight, based on dry weight of the filling material (29, 10), of at least one ingredient having a melting temperature below 180 C., the method comprising ultrasonically welding and cutting an advancing web (32) of packaging material (7) to which the filling material (29, 10) has been supplied. The present disclosure also provides an oral pouched snuff product which is obtainable by this method.

A limb for a breathing circuit manufactured from very thin walled polymer materials has an elongate axial reinforcing spine lying freely inside the conduit and fixed to each end connector. The spine is laterally compliant but axially stiff. The spine provides resistance to tensile and compressive loads on the conduit, including that induced by prevailing internal pressures.

An aerospace vessel including a fuselage, a means for causing the fuselage to fly coupled to the fuselage, and an environmental control system within the fuselage. The environmental control system includes a duct made of closed cell thermoplastic foam, such as polyvinylidene fluoride foam.
