The Standard Horizon HT-1000V Variable Three-Knife Trimmer operates in-line with Horizon perfect binders or off-line to deliver a wide range of input and output sizes for completely variable production. Heavy duty construction allows the trimmer to be run in a 24/7 production environment with consistent high quality finishing.

Hands-free setup: Variable trims are set up by reading a bar code printed on the cover sheet of each book at the entrance of the trimmer, with no operator input required. For same size production runs, the trimmer can be set up offline via touchscreen by inputting the desired untrimmed and finished size.

Variable production: The system trims up to 1,000 books of variable thickness and format size per hour, accepts a broad range of input sizes, and delivers trimmed books from 5.7″ x 4.05″ up to 13.39″ x 11.81″. The system can also trim stacked books with the same untrimmed size and finished format at the same time for high productivity when variable trimming is not required.
