BOBST Premiers New Folder-Gluer for Corrugated, Litho-Laminated Box Making

 

BOBST, Switzerland, has introduced a new folder-gluer for corrugated and litho-laminated box making. Available in two sizes, Expertfold 145 and Expertfold 165, and in several variants, the machine has been designed with the needs of both sheet plant and integrated manufacturers of fluted boxes in mind. The new Expertfold offers true control of the folding and gluing process thanks to a large number of new design features and technology innovations. 

 

 

 

Design elements of the new machine include Accufeed blank alignment that ensures precise folding, a high accuracy pre-breaker that ensures high performance on machine-erect lines, and a folding process that minimizes fishtailing and gap. The latter is aided by an extra-long folding section, which creates smoother folding. Along with revolutionary creasing units at the entry, this ensures the high folding quality that manufacturers need today, BOBST notes. 

 

Able to fold and glue substrates from N-flute to A-flute, including double wall and litho-laminates, the Expertfold 145 and 165  can handle blanks of up to 1,700 x 1,100 mm in size and up to 25 mm thick when folded. The flexibility of the models means that they can also process blanks as small as 296 x 60 mm. 

The range of configurations and options available includes crash-lock capabilities, a  25,000 boxes/hr. 4/6 corner unit, and motorized/automatic setting versions. The high, 250 m/min., running speed of the unit means that end of line handling can become a bottleneck without automatic packing.
