OC-5B / OC-5K / OC-5KB is a basic automatic edge alignment fabric inspection machine for knitted fabrics before cutting or further processing. It is suitable for fabric surface inspection, length confirmation, and basic edge alignment. The machine can adjust roll tension according to fabric roll condition, supporting both loose-roll and tight-roll operation. The distance between the fabric roll and the machine body can also be adjusted according to roll diameter, making it suitable for larger fabric rolls. This series uses a mechanical spiral rod edge alignment system and is designed for general knitted fabric inspection and basic edge control. For factories handling more fabric types or requiring more advanced unwinding, rewinding, and edge control, OC-83 is the recommended advanced model.

The main difference between OC-5B, OC-5K, and OC-5KB is the fabric handling and output configuration. OC-5B includes the feeding system and is suitable for inspection workflows that require fabric feeding. OC-5K includes the plaiting system and is suitable for workflows that require plaited fabric output. OC-5KB includes both feeding and plaiting systems. The appropriate model can be selected according to downstream operations and fabric output requirements.
