Abstract
A mold arrangement for producing a preform element of a wind turbine blade includes a mold carrier and a plate- or tray-like mold element arranged at the mold carrier with a form defining mold surface adapted to receive preform building material, a first heating device arranged below the mold element for heating the preform building material from below the mold element, and a second heating device for heating the preform building material from above.
Claims9
A mold arrangement for producing a preform element of a wind turbine blade, comprising:
- a mold carrier and a mold element arranged at the mold carrier with a form defining mold surface configured to receive preform building material,
- a first heating device arranged below the mold element for heating the preform building material from below the mold element, and
- a second heating device for heating the preform building material from above,
- wherein the second heating device comprises a lid configured to be attached to the mold element and to cover the preform building material while creating a space between the mold surface and the lid, wherein the space is coupled to a heating air source configured to blow a circulating heating air in the space, wherein the lid includes a web splitting the space into a U-shaped air channel, and wherein the U-shaped air channel is coupled at one end to a heating air supply and at the other end to a heating air exhaust.
