Abstract
A cutting machine for trimming three sides of printed products includes blades that are moved up and down in a first cutting station for trimming the front, and in a second cutting station for trimming the top and bottom of the printed products. A transport mechanism is provided for positioning the printed products at adjustable rear stops. The conveying path formed between adjustable stops associated with the cutting stations and the cutting region specified for top and bottom trimming along the conveying path of the printed products are variable.
Claims11
A cutting machine for automatically trimming printed products having a spine and transported spine first along a horizontal path in a transport direction, comprising:
- first and second cutting stations spaced from one another along the horizontal path in the transport direction, each station including at least one clamping bar for pressing against the printed product during a trimming operation;
- and
- transport means for transporting the printed products spine first along a conveying path from the first cutting station to the second cutting station;
- said first cutting station having a reciprocating blade extending transverse to the conveyor path for cutting a front of the printed product, said second cutting station having a two reciprocating blades extending parallel to the conveyor path for cutting a top and a bottom of the printed product, the reciprocating blades of the cutting station being controlled to cut simultaneously;
- and
- wherein both cutting stations each comprise an adjustable stop associated with the respective cutting station, and disposed along the conveying path for the printed products being transported spine first, both of the adjustable stops being adjustable along the conveying path for adjusting a length of the conveying path formed by a spacing between the stops and for adjusting a cutting region for top and bottom trimming of the printed products along the conveying path.
