A system and process for making a container or pouch that separates the cutting and sealing steps into two distinct steps with a separate step of rotating the container or pouch template 90 degrees relative to a direction of travel between the cutting and sealing steps.

The invention relates to a roof rack roof rack for a motor vehicle, having a roof rail profile. The roof rail profile is manufactured from a profile that has a constant cross-section in the longitudinal direction of the profile. Roof rail profiles with different designs can be formed from one and the same profile cross-section, namely by the shaping of a side or wall section present on the profile that delimits a passage. The roof rail profile, which preferably is designed as one piece, has different cross-sections in the longitudinal direction, namely unshaped surface sections and shaped surface sections.

A method and apparatus for forming a pressure vessel liner are disclosed. One method includes forming an extruded tube by extruding a parison through a die and a mandrel and forming main body sections and return line sections in the extruded tube according to a first pattern. A cross-sectional area of the return line sections is smaller than a cross-sectional area of the main body sections. The method further includes changing the pattern according to which the main body sections and the return line sections are formed from the first pattern to a second pattern without stopping the forming of the extruded tube and forming the main body sections and the return line sections in the extruded tube according to the second pattern.

The present invention provides a corrugated tube and a method for manufacturing the same capable of improving workability in press-fitting work of a pipe or a quick connector. A corrugated tube includes a flexible section having a first corrugated section and a second corrugated section, and straight sections integrally formed at both ends of the flexible section respectively. A length of valley portions in an axial center direction is larger than a length of valley portions in the first corrugated section, thereby allows a pitch P2 of mountain portions in the second corrugated section provided between the straight section and the first corrugated section to be larger than a pitch P1 of mountain portions in the first corrugated section.

A method of producing an elastic profile with longitudinally recurring transverse protrusions includes extruding a primary profile at a primary extruder; extruding a secondary profile at a secondary extruder, the secondary profile includes a substrate layer and transverse protrusions, the secondary extruder includes an extrusion die, wherein a rotating molding wheel forms a wall of the extrusion die, the molding wheel having recesses functioning as molds for the transverse protrusions within the extrusion die; joining the primary profile and the substrate layer of the secondary profile at a joining point for fusion bonding forming a composite structure. A rotating pressing wheel, may press on the composite structure against a bedding separate from the molding wheel. The primary profile may travel along an entirely straight path from the primary extruder to the joining point. The joining occurs at a nip formed between the molding wheel and a flat and stationary bedding.

Silicone-containing light fixture optics. A method for manufacturing an optical component may include mixing two precursors of silicone, opening a first gate of an optic forming device, moving the silicone mixture from the extrusion machine into the optic forming device, cooling the silicone mixture as it enters the optic forming device, filling a mold within the optic forming device with the silicone mixture, closing the first gate, and heating the silicone mixture in the mold to at least partially cure the silicone. Alternatively, a method for manufacturing an optical component may include depositing a layer of heat cured silicone optical material to an optical structure, arranging one or more at least partially cured silicone optics on the layer of heat cured silicone optical material, and heating the heat cured silicone optical material to permanently adhere the one or more at least partially cured silicone optics to the optical structure.
