ABSTRACT:
A pre-preg pre-cut tape 20 is made by the steps of converting the forms of a pre-preg to be cut into co-ordinates on a pre-preg tape 2 from the data on the form of lamination and the condition of lamination to form the data on the form to be cut, forming the data on the forms of unnecessary portions showing the forms of the unnecessary portions 4 from the data on the forms to be cut, forming the data on division for dividing the forms of the unnecessary portions into the forms of (a) to (f) removable from a mold releasing paper, and forming the data on the direction of removal for showing the direction of removing the unnecessary portions of (a) to (f) divided on the basis of the data on division, whereby the unnecessary portions 4 are removed on the basis of such data.
