Standard Finishing Systems (Booth 1244) will be showing the new Horizon HT-1000V Variable Three-knife Trimmer for true on demand book production of variable sizes. The 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! Setup and variable trimming are achieved automatically by reading a barcode printed on the cover sheet of each book at the entrance of the trimmer, with no operator input required. The system trims up to 1000 books of variable thickness and format size per hour and will accept a broad range of input sizes and deliver trimmed books from 5.7x4.05 inches up to 13.38x11.69 inches. The heavy duty construction allows the trimmer to be run in a 24/7 production environment with consistent high quality finishing. A uniquely designed, automated trim removal system ensures consistent running without jamming. The system can also trim stacked books of the same untrimmed size and finished format at the same time, up to 2.55 inches in height, for high productivity when variable trimming is not required. For same size production runs, the trimmer can be set-up offline via the touch screen by inputting the desired untrimmed and finished size.
