Title:
METHOD AND APPARATUS FOR FORMING THIN-BOARD-LIKE BASE MATERIAL
Document Type and Number:
WIPO Patent Application WO/2014/132543
Kind Code:
A1
Abstract:
Provided is a forming method whereby a time needed to form a thin-board-like base material is shortened, while maintaining forming accuracy of the thin-board-like base material, and productivity relating to the formation of the thin-board-like base material can be improved. This method for forming a thin-board-like base material has a tensile transfer step and a forming step. In the tensile transfer step, the long thin-board-like base material is transferred by pulling the thin-board-like base material in the transfer direction, while holding both the thin-board-like base material ends along the transfer direction and pulling the ends outward in the direction intersecting the transfer direction. In the forming step, predetermined forming operations are performed with respect to the thin-board-like base material.
