HX460D Semi Automatic Thread Sewing Machine for Gathered Signatures with Centralized Lubrication

The HX460D Semi-Automatic Book Sewing Machine is designed for thread sewing of gathered signatures in sizes from 150 × 100 mm to 460 × 320 mm. The operator manually places signatures on the feeding station, and the machine automatically completes signature feeding, sewing, thread cutting, counting and book block delivery at speeds of 20 to 80 cycles/min.
It supports up to 14 sets of fine needles with a minimum 16 mm needle pitch for dense and precise sewing. The PLC control system, variable-frequency drive, color touchscreen, LED lighting and photoelectric sensors provide automatic monitoring of thread breakage, broken needles, thread-hooking failure, and missing or multiple signatures.
A heat-treated wear-resistant cam system, adjustable bearing rollers and centralized lubrication ensure accurate needle alignment and stable long-term operation. The machine is suitable for both softcover and hardcover book production.

• High Productivity: Sewing speeds of up to 80 cycles/min, supporting up to 14 sets of fine needles with a minimum 16 mm needle pitch for dense and precise sewing.
• Intelligent Control: Equipped with a PLC control system, variable-frequency drive, color touchscreen, and LED lighting for intuitive and convenient operation.
• Precision & Safety Monitoring: Photoelectric sensors provide automatic monitoring for thread breakage, broken needles, thread-hooking failure, and missing or multiple signatures.
• Durable & Stable Design: Features a heat-treated wear-resistant cam system, adjustable bearing rollers, and a centralized lubrication system to ensure accurate needle alignment and stable long-term operation.
• Versatile Application: Perfectly suited for both softcover and hardcover book production.

The HX460D combines programmable PLC control with fine needle sewing capability in a semi-automatic format. It handles signature sizes from 150 × 100 mm to 460 × 320 mm, supports up to 14 needle sets at a 16 mm minimum pitch, and runs at 20–80 cycles/min. The photoelectric monitoring system automatically detects thread breakage, broken needles, hooking failures and signature errors, reducing defective output. The heat-treated cam system and centralized lubrication support long-term precision, making it suitable for both softcover and hardcover production environments.
