Abstract

A method and machine for cutting a sheet (1) into a plurality of pieces (2) and collating them first forms a plurality of slits (3) parallel to one pair of edges (4), and ending short of the other pair of edges (5), next cuts along a plurality of lines (6) parallel to that other pair of edges (5), and with two lines (6) intersecting the ends of the slits (3), then feeds the pieces (2) in the lengthwise direction of the two strips (7) left beyond the cut ends of the slits (3) and allows the two strips (7) to fall away, allows the pieces (D, H, M, R, V, Z) at one end of the rows perpendicular to the direction of feed to drop to a lower level, superimposes a transverse feed on the remaining pieces (2) towards the dropped pieces (D, H, M, R, V, Z), whereby they are dropped in order to form batches (9), and finally allows the batches (9) to fall successively on to a substantially stationary support (33) to form a stack (10) of the pieces (2) in definite order. The machine is capable of completing the method in no more than one-and-a-half seconds, including trimming off initial margins (11) to form the edges (4) parallel to the slits (3) accurately.
