Signal transmission component processing device, has wheel with contactless rotary joint formed between transmitter and receiver for signal transmission, where joint is in form of circular ring and stretches itself around through hole

摘要

The device has a rotatable support wheel with a feeding unit for a working material. The wheel has a rotary coupling, and a contactless rotary joint (40) is formed between a transmitter (41) and a receiver (42) to transmit signals. The joint is formed in a shape of a circular ring, and stretches itself around a through hole (43). Control units are arranged above the wheel, and components used in the units are placed outside the wheel.
