The AUSCP SX220/43 consists of a thread separating mechanism, page turning mechanism, conveying mechanism, positioning mechanism, sewing mechanism, wire cutting mechanism, book separating mechanism, wire cutting head mechanism, and intelligent control system. The machine is designed integrally and does not need to be disassembled for relocation or transportation.

​
● High speed and precision: maximum speed of up to 220 signatures per minute, with three fully sealed cam control boxes filled with lubricating oil for smooth and durable operation. The flywheel accurately drives paper feeding, conveying, and saddle stitching. The book signature on the saddle is precisely positioned through synchronized belt structure with puller.
● Intelligent debugging: Colored touchscreen monitors the entire production including paper feeding, conveying, lockstitching, and receiving, ensuring the quality of lockstitching.
● Fault detection & identifying: When faults such as missing signatures, multi-signatures, jams, dropped signatures, shortened signatures, and broken signatures occur, the machine will alarm and pause, while displaying the fault.
● Automatic mis-signature detection function (optional).
● Memory storage: can store 20 different book sewing programs and recall them as needed.
● Automatic plate adjustment: by setting the size of the signature on the touch screen and confirming the page turning method, the transmission system automatically positions the conveyor belt, opens the page turner, adjusts the position of the fixed saddle drive chain and acceleration wheel, and adjusts the height of the finished book platform. Simple and easy to learn, fast operation, and quick plate switching, which improves production efficiency.
● Signature separation: the blower and mechanical arm separate the bottom signature from the pile, and the suction cup extracts the separated signature from the feeder. The tilting device helps eliminate scratches on the surface of the signature.
● Automatic page-turning: the page-turner is equipped with four programmable vacuum suction devices, both the upper and lower sides, which can perform 4+4 vacuum page turning, and can handle signatures with even or uneven tops and bottoms. It can automatically flip through sets of pages, loose pages, pages without long or short edges, and unevenly thick signature It can also turn pages of signatures with edges over 8mm long or short.
● Signature conveying: the signature is placed on the conveying saddle after being turned and is pushed by the conveyor chain hook. The acceleration wheel sends the signature into the active lockstitch saddle, and the speed of the acceleration wheel automatically adjusts according to the speed of the machine.
● Automatic signature separation and thread cutting: the automatic signature separation and thread cutting device (cuts the excess thread to about 8-10mm for easy binding) can separate the book signatures one by one according to the setting, regardless of the number of signatures in the book.
● Flat lock: uses fine ultra-short needles (¢16mm) with a narrow stich spacing (19mm) to make the product flatter and less prone to glue leakage, ensuring high-quality book sewing. The lockstitch device consists of cam box type equipment, which not only reduces noise but also extends the life of the cam. ​
● On-demand lubrication: Centralized oil supply lubrication system that can send an alert if the oil pressure is insufficient. Equipped with timed and metered lubrication devices, the lubrication oil is delivered to the required points through the lubrication pipeline on a timed and metered basis while the machine is running.
