A new folder gluer for corrugated and litho-laminated boxmaking from Bobst has been designed with the needs of both sheet plant and integrated manufacturers of fluted boxes in mind. It is available in two sizes, the Expertfold 145 and 165.
A number of new design features and technology innovations are said to give this new machine "true control of the folding and gluing process".
Emilio Corti, head of sales BU Sheet-fed, says, "We conceived the Expertfold 145 and 165 to reflect what customers told us they need from a folder gluer. One feature they asked for was flexibility in the type and dimensions of the substrates that could be run. They also wanted good control of the blank as it goes through the machine in order to achieve high performance with excellent box quality. That control is particularly important these days with so much production being shelf-ready packaging or destined for auto packing lines."
The design elements of the new Expertfold which deliver these features include: Accufeed blank alignment that ensures precise folding; a high accuracy pre-breaker which ensure excellent 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.
Able to fold and glue substrates from N-flute to A-flute, including double wall and litho-laminates, the new Bobst machine can handle blanks of up to 1,700 x 1,100mm in size and up to 25mm thick when folded. The flexibility of the models means that they can also process blanks as small as 296 x 60mm.
