Abstract (en)
A waste removing apparatus, for use in a punching machine for manufacturing a carton, for separating from each other a waste region (17) of a sheet and a product region (18) of the sheet having a punching line (12) comprising a cut-out portion (19) and a remaining portion (20) formed thereon and inserted between an upper die (11) and a lower die (12) which are approached to each other, by pressing down the waste region and tearing the remaining portion by means of a punching member (13) projecting downward from one of the dies so as to remove the waste region from the sheet. A plurality of grooves (30) is formed on a surface (26a) of the punching member to be brought into contact with a surface of the waste region to form pressing portions (31) between the grooves at regular intervals. <IMAGE>
