摘要

Apparatus for folding a sheet 6 by transferring it from cylinder 1 into jaw 30 of cylinder 3 using blade 5, can also operate to transfer the sheet from cylinder 1 to cylinder 3 without folding. The peripheral spacing of gripper 10 from jaw 30 is fixed and equal to a (half the sheet length) plus an increment (a' + a"). The peripheral spacing of blade 5 from gripper 4 is adjustable. In folding mode (shown), gripper 10 precedes the front of the sheet into the nip and does not grip the sheet. For non-folding mode (figure 2), blade 5 is moved clockwise by (a' + a") away from gripper 4, and the whole of cylinder 3 is moved anticlockwise by (a' + a"), so that grippers 4 and 10 coincide in the nip; blades 5 are de-activated in this mode.
