The overhead railing will be looped between all spinning frames and all speed frames group as in the enclosed drawing.
Full bobbins will be moved manually to the buffer area. If the requirement is made in the ring frame then the doffer will move the train to the ring frame.
Overhead rails are made of aluminium and the trains are also made of aluminium and anodized for smooth finish and corrosion free. Main and guide rollers are made of Acetate – plastic with high precision bearings. The connecting tube design allows exact tangential travelling of train to have minimum wear.
Empty tubes and full bobbins are manually loaded on to the trains running in the overhead railing in ring frame and speed frames randomly / whenever required as shown in the picture. Like this, whenever full bobbins are empties required, it will be removed manually from the trains running in the overhead railing.
