Faller advance and reverse mechanism - has transfer wheels mounted with the gill screw pairs with faller pressed against them

摘要

An appts. is claimed for the advance and retraction of fallers, where gill screw pairs are located at each end of the fallers, with transfer wheels, located in parallel to the plane of the gill screws, at the ends of the faller. Circular channels are provided close to the circumference of the transfer wheels to maintain the orientation of the needles, together with leaf springs to ensure that the faller is pressed against the transfer wheels while passing round them. The design allows the fallers to be advanced and retarded at high speeds, keeping them in a circle as they pass round the end wheels, preventing any tendency to follow a rectangular course which would affect their smooth running.
