Composite material forming jig, composite material forming method and composite material
According to one implementation, a composite material forming jig includes molds and a tilting structure. The molds are developable for laminating fiber sheets, after or before impregnated with a resin, in a developed state where the molds are developed. At least one mold of the molds is capable of being inclined relatively to another mold of the molds so that the laminated fiber sheets are shaped. The tilting structure is adapted to develop the molds when the fiber sheets are laminated and incline the at least one mold when the laminated fiber sheets are shaped.

MOULDING UNIT WITH BISTABLE MAGNETIC DEVICE
The invention relates to a unit for molding containers, which comprises two mold supports, a device for locking the mold supports in the closed position, and a bistable device which comprises a fixed element and a mobile element able to move between two stable extreme positions. The mobile element comprises a mobile magnetic dipole, and the fixed element comprises a fixed magnetic dipole, the fixed magnetic dipole applying a magnetic force from a distance to the mobile magnetic dipole in order to force the mobile element toward one or other of its two stable extreme positions.
ESCAPE PATH FOR A PRODUCTION MOLD OF A ROTOR BLADE
The invention relates to a production mold for a rotor blade of a wind turbine plant, having two mold half-shells (3, 4) which during a production method of the rotor blade are disposed so as to be at least temporarily beside one another, and having at least one inner walkway (2c, 2d) that runs along so as to be between the two mold half-shells (3, 4), characterized by at least one escape path (40) which runs along below at least one of the two mold half-shells (3, 4).
BLOW MOLDING MACHINE WITH AUTOMATICALLY ACTUATED BASE COUPLING
A system is provided for transforming plastic parisons into plastic containers with at least one transforming station which has a blow mold within which the plastic parisons can be expanded by application of a gaseous medium, wherein the blow mold has a base part which is disposed releasably on a support, and with a first fastening mechanism in order to fasten the base part to the support, and wherein the blow mold has at least one side part which is disposed releasably on a support and a second fastening mechanism in order to fasten the side part to the support.

MOLDING TOOL ASSEMBLY
A molding tool assembly, in particular for producing rotor blades of wind power plants, having a first mold shell (20) and a second mold shell (22) each for receiving one workpiece part, wherein the two mold shells in a proximal position face one another but do not bear on one another, having securing means for holding a workpiece part in at least one of the mold shells and having centering means for mutually centering the two mold shells in the proximal position or during convergence of the mold shells. The centering means and the securing means are mechanically intercoupled.
ADJUSTABLE MOLDING SYSTEM FOR FORMING MATERIAL ON PIPE
A molding system for applying insulation to a pipe employs an elongate mold in which to receive the pipe. A mold adjustment mechanism can adjust a shape of the mold to correspond to a shape of the pipe as the pipe sags in the mold cavity. In a method of insulating the pipe, the shape of the mold is adjusted to correspond to the shape of the sagging pipe and curable material is imparted into the mold while maintaining the adjusted shape of the mold. The elongate mold can include at least one double-walled mold member with an inner form wall, an outer jacket, and a plurality of radial supports that support the outer jacket on the inner form wall in radially spaced apart relation therewith.
