摘要:
A printing press is provided. The printing press includes at least one printing unit printing on a web, a folder for forming the web into a plurality of signatures, the plurality of signatures traveling in a stream at an initial pitch and a pitch changing device for changing the initial pitch of the plurality of signatures in the stream. The pitch changing device includes a first orbiting member orbiting about a first axis and rotating about a second axis and a second orbiting member orbiting about a third axis and rotating about a fourth axis. The first orbiting member and second orbiting member form a nip and the nip receives a stream of signatures. The first and second orbiting members vary a velocity of the signatures so as to alter the initial pitch. A folder and a method for changing a pitch between consecutive signatures is also provided.
