    Abstract: Embodiments of a method and a mold for producing a concrete pipe comprising a basic body made of concrete and a plastic inner pipe for conducting a liquid. The method comprises introducing a mold core into the plastic inner pipe, introducing the plastic inner pipe into an outer mold and pouring concrete into an intermediate space between the outer mold and the plastic inner pipe to form the basic body. After the concrete has solidified, the plastic inner pipe remains as inner formwork in the basic body made of concrete and the mold core is removed.

    Abstract: The invention relates to the use of a native or modified leguminous starch for producing an adhesive labeling composition. Said leguminous starch has an amylose content ranging between 25 and 60 percent by weight (dry/dry) and can be embodied as pea starch, especially pea starch having an amylose content of at least 30 percent but less than 50 percent by weight. The adhesive composition can advantageously be used for labeling glass or plastic bottles and can contain another natural polysaccharide polymer or protein polymer in addition to the leguminous starch, for example another native or modified leguminous or non-leguminous starch, particularly a starch having an amylopectin content of at least 80 percent by weight (dry/dry). The use of a leguminous starch makes it possible to obtain labeling adhesives, optionally highly dry (>40%) substances, which have excellent characteristics regarding stability during storage, rheology, and water resistance.

    Abstract: A method and an apparatus for manufacturing of a curved elongated structural element of composite material. The curved elongated structural element includes a first elongated portion and a second elongated portion in an angled relation. A substantially flat blank of composite material including a first and second elongated edge is provided. The blank is folded over a first portion forming surface and a second portion forming surface of a forming tool's flexible tool body for forming the first elongated portion and the second elongated portion. The forming tool's tool body is bent such that its bending moment center prevails essentially adjacent the first portion forming surface.

    Abstract: In a continuous molding apparatus equipped with a long core 10 having a curvature disposed on a plane, a release film supplied from a lower release film feeder 20 is sent onto the core 10, and prepreg sheets supplied from a prepreg sheet feeder 30 are laminated thereon and preformed. A release film supplied from a release film feeder 40 is disposed on top of the laminated body, before the body is sent into a hot press 50. A puller 60 moves the laminated body without loading tension thereto. The laminated body enters a postcure device 70 in which thermosetting of the material is completed.
