Abstract: Apparatus and methods of fabricating half products in the field of puffed snack piece fabrication are disclosed including a rotary cutter (16) having an opposed pair of rollers (18). At least one of the rollers (18) of the rotary cutter (16) has cavities (112) arranged in a first, central portion (110) which stamp out first pieces and cavities (118) arranged in second and third, boundary portions (114, 116) for stamping out second pieces from the remaining portions of a continuous dough sheet (14). The first pieces are of the desired shape and size for the half products, and the second pieces are of a size and shape mechanically separable from the first pieces. After stamping, the first and second pieces are dried in an oven (134) and then separated by a separator (136). The dried first pieces form the half product. The dried second pieces can be ground in a grinder (138) and added to the ingredients (120) forming the dough prior to or during mixing in mixer (122).
