FIELD: process engineering.
SUBSTANCE: invention relates to metal forming and may be used for drawing half-stock from blanks. Blanks are cut, one after another, at definite spacing set by equipment feeder with the help of one die of series action or several dies of single action mounted at said equipment. All versions allow cutting of blanks at the reel centre without webs between adjacent blanks. Top web between blanks and top edge of the reel is divided in top and bottom parts in line which makes them a merchantable waste. Outline of one blank is partially located inside that of another blank which add to saving of sheet material.
EFFECT: better processing.
