An apparatus for spacing and aligning triangular-like shaped pieces of food dough in one direction, which pieces are arranged so that they form a plurality of columns, wherein the directions of the pieces of the adjacent columns are alternately opposite each other, by rotating the pieces clockwise and counterclockwise at 90 degrees.The apparatus continues to alternately rotate the pieces 9 clockwise and counterclockwise at 90 degrees, which pieces 9 are cut and separated from a sheet 7 of food dough and are carried sequentially downstream from upstream by conveyors 3, 5, comprising pin-holding members 67 fixed to rotating rods 63, which rods 63 can move vertically and rotate clockwise and counterclockwise at 90 degrees, wherein the pieces 9 can be aligned so that one of the apexes of the triangular-like-shaped pieces 9 is oriented toward the upstream side of the direction for carrying the pieces 9.
