A center portion (30) of a V-shaped cutter blade (20) includes center large teeth (31) and center middle teeth 32 the tooth height of which is less than the tooth height of the center large teeth (31). End portions (50) of the cutter blade (20) each include first end teeth (51) and second end teeth (52) the tooth height of which is less than the tooth height of the first end teeth (51). Tooth tops of the first end teeth 51 of each end portion (50) are located on a straight line (L1), which extends through tooth tops of the center large teeth (31) located on one of the right half and the left half of the center portion (30).
摘要:
A contact roll winding device comprises a contact roll, a cutting device, a winding station with a winding shaft receiving device, and two guide rollers, one of which guides a sheet of material to the contact roll during a counterclockwise winding operation, while the other, which is arranged symmetrically with respect to the cutting device, guides the sheet of material to the contact roll during a clockwise winding operation. After the sheet of material has been cut by the cutting device, it is held against the contact roll by negative pressure until the leading end of the sheet of material reaches the winding station where there is a new winding shaft.
