A filler preform in a wedge form includes reinforcing fiber bundles consisting of reinforcing fiber filaments, wherein the filaments are directed parallel to each other within the fiber bundle, wherein the fiber bundle contains a first resin composition in a concentration in the range from 1 to 10 wt. % relative to the fiber weight, wherein the fiber bundles have a length in the range from 2 to 20 mm and at least 60% of the fiber bundles are reversibly fixed in a curved form within the wedge filler preform whereby flanks of the curved fiber bundles create an opening angle of less than 120° and the opening angle of the curved fiber bundles relates with an opening angle of the wedge form of the wedge filler preform. A method for producing the wedge filler preform and a method for producing a reinforcing fiber composite include a filler perform.

A portable molding system is configured for forming insulation on pipes. A set of transportable process modules are configured to be shipped to a molding site, operatively connected together at the molding site to form a site-installed molding system, and subsequently disconnected for transport to another site. The set of transportable process modules includes one or more resin preparation modules configured to prepare resin for being formed into insulation on the pipes. One or more mold modules are configured to define a mold cavity. The one or more mold modules are configured to hold a pipe in the mold cavity, to receive resin prepared by the one or more resin preparation modules in the mold cavity around the pipe, and to form said resin received in the mold cavity into insulation on the pipe.

A turning system for turning wind turbine blade shell part carriers between an open position and a closed position about a turning axis, comprising: a lower blade shell part carrier having a support surface for receiving and supporting a lower wind turbine blade part; an upper blade shell part carrier and having a support surface for receiving and supporting an upper wind turbine blade part; and at least one turning device each including: a lower hinge element, such as a beam, arranged under the support surface of the lower blade shell part carrier; and a turning hinge having a lower hinge part attached to the respective lower hinge element, an upper hinge part attached to the upper blade shell part carrier, and an actuator configured for turning the lower and upper hinge parts relative to each other about the turning axis.

Disclosed is a clamping tong for securing a shell part of a wind turbine blade in a mould and a mould comprising a clamping tong. The clamping tong comprises a first tong segment, a second tong segment and a third tong segment. The third tong segment has a clamping surface for applying a clamping force on a mould section, such as a mould flange of the mould. The clamping tong is configured to reposition the clamping surface between a clamping state and a release state. The distance between the clamping surface and the first tong axis in the clamping state is shorter than the distance between the clamping surface and the first tong axis in the release state. Thereby, the clamping surface may provide the clamping force on the mould section in the clamping state. The first tong segment is attachable to the mould.

A method and apparatus for operating an apparatus for transforming plastic parisons into plastic containers, wherein the apparatus has a movable carrier, on which a plurality of transforming stations are arranged for transforming plastic parisons into plastic containers. The transforming stations each have at least two mould supports on which blow mould parts are arranged, which blow mould parts are components of a blow mould and form a hollow space within which the plastic parisons can be expanded into the plastic containers by application of a flowable medium. The mould supports are pivotable with respect to one another for opening and closing the blow mould and wherein furthermore the transforming stations have a latching mechanism which is configured to latch the two mould supports at least at times to one another such that an opening movement of the blow mould is prevented.
