Disclosed herein is a molded laminated structure having negative draft angles and methods of manufacturing a molded laminated structure having negative draft angles. A preliminary structure having a first outer layer and a second outer layer is molded with a bend that divides the preliminary structure into two sections with an angle between the two sections of less than 180-degrees. Portions that extends from the sections are at positive draft angles. A groove is formed in the preliminary structure at the bend but not formed in a constant cross-section of the second outer layer. The preliminary structure is folding along the bend to at least partially close the groove and form a molded laminated structure with portions that extend at a negative draft configuration while retaining the second outer layer continuous throughout the molded laminated structure.

A method of producing an exercise weight structure comprises mixing a particulate material with a binder material and molding the resulting mixture to an appropriate shape. An outer skin for the exercise weight structure is firstly formed of a resilient material, and forms a mold into which an inner weight section or body is molded or cast. The inner weight section and the outer skin are both formed of recycled material and include a common binder material.

A dispenser apparatus for a curable liquid material is disclosed. The apparatus comprises a flexible bag defining a first compartment for accommodating a first component of a curable liquid material, and a second compartment for accommodating a second component of the curable liquid material and adapted to communicate with the first chamber to enable mixing of the first and second components to initiate curing of the curable liquid material. A first clamp temporarily prevents mixing of the first and second components, and an elongate nozzle communicates with the second compartment to dispense the mixed curable liquid material therefrom. A second clamp temporarily prevents passage of the curable liquid material from the second compartment to the nozzle.

A method of manufacture of a shaft including positioning a prefabricated wedge member onto a cylindrical mandrel, winding a fibre material onto the mandrel, the fibre material extending over at least a part of the wedge member, allowing a matrix material impregnated into the fibre material to cure, and machining away at least part of the fibre material in the region of the wedge member to expose fibres thereof.

A mould for moulding materials, the mould comprising at least two corresponding mould elements (14, 16, 18, 20) moveable relative to one another towards and away from each other, the towards movement exerting pressure on a moulding material positioned within a cavity formed with the mould wherein upon the mould elements being in contact the mould cavity comprises a recess (120), the recess (120) being located beyond the edge of the moulding to allow escape of gas (12) during moulding.

A method for manufacturing a tension member, in particular for use in a belt or in a belt segment, having the steps of: preparing a tension member which has a plurality of tension member strands and filling at least some of the intermediate spaces between the tension member strands with a filling material at least at one open end of the tension member, wherein the tension member remains free of the filling material toward the outside.

A composite element and a method of manufacturing the same. The composite element comprises a first skin plate and second skin plate, which are manufactured as separate pieces and are assembled in a separate phase. At least the first skin plate comprises several protrusions on an outer surface of the plate. The protrusions serve as local stiffeners and are further stiffened by means of one or more additional composite structures arranged inside the protrusions.
