Abstract:
Sailboards having a tucked rail are made from a flexible, resilient mold so that the seam of the board is along its bottom edge instead of at its point of greatest breadth. A flexible mold part having the contour of the sailboard to be produced has an opening smaller than the greatest breadth of the board. The mold is first flexed so that its opening is sufficiently wide to receive the blank that forms the body of the sailboard. Secondly, the blank is inserted into the flexed mold, and thirdly, the mold is released and its resiliency returns it to its original shape. A conventional rigid mold part closes the open end, and a vacuum is applied to form the final product. The flexible mold part is flexed a second time to remove the product.
