The Horizon HT-30 is a used guillotine — sometimes referred to as a book trimmer or three-side trimmer — designed for the offline trimming of perfect-bound and other bookblock formats. Rather than using three separate knives as a conventional three-knife trimmer does, it achieves three-sided trimming with a single knife, working through a programmed cycle that cuts the head, foot, and fore-edge in sequence. Horizon is a well-established Japanese manufacturer of post-press finishing equipment, supplying the commercial print and bookbinding industries with machinery including trimmers, folders, collators, and saddle-stitching lines.
The HT-30 operates with a high degree of autonomy: the operator enters the book format and the required quantity via a Touch & Work touchscreen display, and the machine completes the trimming run unsupervised. This makes it a practical and cost-effective solution for short-run work that does not justify a full three-knife trimmer.
The machine accommodates an untrimmed format range from a minimum of 200 × 134 mm up to a maximum of 320 × 235 mm, with trimmed output ranging from 200 × 134 mm at the smallest to 305 × 230 mm at the largest. Maximum block thickness is 51 mm, covering a broad range of bookblock depths typical in short-run digital and litho print production. Contact pressure is adjustable between 1.5 and 8 kN, allowing the operator to match clamping force to the block being trimmed. Production speed runs from 220 to 520 cycles per hour depending on the format and configuration in use.
The machine's footprint is 2,350 mm wide, 1,160 mm deep, and 1,370 mm high. This 2005 machine is located in Germany and is offered in used condition.
