METODO PROPRIO PARA A FORMACAO DE LINHAS DE CORTE EM FOLHAS |
摘要 |
<p>There is disclosed a cut line forming method including: using a cutter roll (1) having cutting blades (2) protruded on its outer circumference and an anvil roll (10) for receiving the cutting blades; feeding a sheet (20) into the clearance between the cutter roll and the anvil roll; and turning the rolls individually to form cut lines (21) in the sheet. The cutting blades (2) of the cutter roll (10) are formed into a shape of letter "V". The anvil roll has receiving faces (11) of a predetermined width (w) formed at an interval in a roll axis direction. The cutter roll (1) is turned to direct the crests of the V-shape of the cutting blades forward of the turning direction thereby to advance cuts from the side of the crests of the V-shape so that cut lines corresponding to the width size of the receiving faces may be intermittently formed in the sheet along the V-shape.</p> |
