Bobbin elevators in bobbin transport devices

摘要

Bobbin transport devices with a swingable carrier and a bobbin receiving member adapted in a first pivot position to align with a bobbin on a winding machine, a second swingable carrier with its own bobbin receiving member which aligns with the first bobbin receiving member, a shifting member for varying the distance between the two bobbin receiving members, e.g., a piston rod adapted to engage the bobbin on a slide or trolley member for one swingable carrier, and a rack and pinion or pressurized fluid operated lift for the aforementioned structures.
