Picker-wheel support structure was used in strip label papers of tobacco industry, but it had appeared some problems: picker-wheel vibrates easily, label paper was picked insecurely, and double-shafts generated deformation and linear bearings wear easily. The ultimate cause was founded by analyzing linear bearings stress from statics and dynamics. The original structure of double-shafts one-side support was replaced by two-side support with one fixed end and one free end.
