Abstract: The present invention relates to an apparatus and method for forming molded tapered products, such as masonry blocks, whereby high quality finished products are removed from their mold without the need for complex machinery for demolding. The mold may include one or more mold cavities having one or more movable cavity walls. The movable cavity walls may include an end liner having a planar product forming surface capable of moving from a vertical position to an angled position. Tapered products may be formed by moving the mold towards a pallet so that the pallet engages with the end liner and causes the end liner to move from the vertical position to the angled position. Moldable material may then be introduced into the mold cavity and may be allowed to remain in the mold cavity until it is self-sustaining.

Abstract: The invention relates to a device for the production of an angle for connecting a fuselage cell skin to an annular former and/or a stringer inside a fuselage cell structure of an aircraft, the angle taking place by the one-step deformation of an initially planar blank along at least three fold lines in a uniaxial compression molding device. A mounting frame with hinges is arranged in the compression molding device, the blank to be deformed being accommodated along the edges preferably by means of a plurality of peripherally arranged springs. A deformation of the blank into an auto-stabilized angle is possible in one step while simultaneously ensuring interlaminar slide. Due to the constructively conditioned auto-stabilization of the angle, additional components which increase the weight and the assembly effort (so-called “stabilos”) in the connection region between fuselage cell skin, stringers and annular formers inside a fuselage structure of an aircraft are unnecessary.

Abstract: A structural component having a curved wall, such as an aircraft fuselage pipe, has a grid structure formed of box frames produced by winding tapes of fiber reinforced synthetic material, so-called prepregs, onto mold bodies. These mold bodies are then assembled on a mandrel for covering with a planking and curing whereby the tapes are bonded together to form stringers intersecting with ribs in a grid structure and whereby the planking is bonded to the grid structure. The ribs are reinforced by fiber reinforced belt segments of synthetic material inserted into gaps between adjacent short ends of the mold bodies, whereby these belt segments are bonded to the ribs during curing. The belt segments ave a width corresponding to a multiple of the width of the stringers and hence protrude radially inwardly. Preferably, an edge reinforcing strip of fiber reinforced material is arranged alongside the radially inner edge of the belt segments.
