Abstract
A carrier plate for a preform manufacturing arrangement for producing a preform element for a wind turbine blade is provided, adapted to receive either a mold element with preform building material on a receiving surface or to directly receive the preform building material on the receiving surface, with the carrier plate having a rectangular shape with a longer longitudinal axis and a shorter transverse axis, wherein the carrier plate is flexible around the longitudinal axis but stiffened against bending around the transverse axis, and stretchable along the transverse axis but stiff along the longitudinal axis.
Claims15
A one-piece carrier plate for a preform manufacturing arrangement for producing a preform element for a wind turbine blade, configured to either receive a mold element with preform building material on a receiving surface or to directly receive the preform building material on the receiving surface, with the one-piece carrier plate having a rectangular shape with a longer longitudinal axis and a shorter transverse axis, wherein the one-piece carrier plate is flexible around the longitudinal axis but stiffened against bending around the transverse axis, and stretchable along the transverse axis but stiff along the longitudinal axis, wherein one or more geometric stretching sections allowing stretching along the transverse axis and having a spring-like character are formed at the one-piece carrier plate.
A mold arrangement for producing a preform element of a wind turbine blade, comprising:
- a mold carrier with a receiving section configured to receive a transferable one-piece carrier plate, the one-piece carrier plate having a rectangular shape with a longer longitudinal axis and a shorter transverse axis, wherein the one-piece carrier plate is flexible around the longitudinal axis but stiffened against bending around the transverse axis, and stretchable along the transverse axis but stiff along the longitudinal axis, wherein one or more geometric stretching sections allowing stretching along the transverse axis and having a spring-like character are formed at the one-piece carrier plate,
- wherein the receiving section is built by a receiving plate having a receiving receptacle with a tray-like form configured to receive the one-piece carrier plate which adapts its form to the tray-like form by bending around its longitudinal axis, wherein the receiving receptacle is provided with one or more grooves each being configured to receive a respective stretching section of the one-piece carrier plate,
- or wherein the receiving section is built by a grid comprising a number of rods extending in the longitudinal direction of the mold carrier, wherein the grid is provided with one or more fixation elements for fixating the carrier plate, wherein the one or more fixation elements include a gripper configured to grip a respective stretching section of the one-piece carrier plate.
