Method of and apparatus for cutting sheet-material

A sheet-material cutting method of sequentially cutting a fed lengthy sheet-material into a cut segment and a remaining portion by dint of a shearing force caused by engaging a fixed cutting edge with a movable cutting edge making a relative movement, said edges being disposed vis-a-vis with each other, each operating cycle comprising the steps of:

• (a) feeding a sheet-material with a first amount of feed in between said fixed cutting edge and said movable cutting edge;
• (b) cutting said sheet-material into a first cut segment and a first remaining portion;
• (c) feeding said sheet-material by a second amount, greater than said first amount;
• (d) cutting said sheet-material into a second cut segment and a second remaining portion;
• (e) feeding said second remaining portion with a third predetermined amount of feed, smaller than said first and second amounts, in between said fixed cutting edge and said movable cutting edge in order to bring the sheet-material into a standby state prior to execution of a subsequent operating cycle;
• (f) preventing the top of said second remaining portion from shifting with a disengaging motion of said movable cutting edge;
• and
• (g) repeating all of steps (a) to (f) until all of said lengthy sheet-material has been fed and cut.

A sheet-material cutting method of sequentially cutting a fed lengthy photographic sheet-material into a cut segment and a remaining portion by dint of a shearing force caused by engaging a fixed cutting edge with a movable cutting edge making a relative movement, said edges being disposed vis-a-vis with each other, comprising the steps of:

• (a) feeding a photographic sheet-material with a first amount of feed in between said fixed cutting edge and said movable cutting edge after printing an image on a segment of said photographic sheet-material;
• (b) cutting said sheet-material into an unnecessary end thereof and a first remaining portion including said printed segment;
• (c) feeding said sheet-material by a second amount, greater than said first amount, in order to align said movable cutting edge with a rear end of said printed segment;
• (d) cutting said sheet-material into said printed segment and a second remaining portion;
• (e) feeding said second remaining portion with a third predetermined amount of feed, smaller than said first and second amounts, in between said fixed cutting edge and said movable cutting edge so as to place said photographic sheet-material in a standby condition for printing, so as to enable said second remaining portion to be fed again smoothly even when a wound curl of said second remaining portion occurs while said photographic sheet-material is in said standby condition;
• and
• (f) preventing the top of said second remaining portion from shifting with a disengaging motion of said movable cutting edge.
