Abstract
A folding station of a folding box gluing machine for processing a blank having a middle piece and side pieces which are attached to sides of the middle piece and which are deflected upward and inward along folding grooves between the middle piece and the side piece across a folding line toward the lengthwise middle of the blank and then folded up in order to produce a folding boxes, includes a folding strap that deflects the side pieces and folds them upward. The folding strap is guided by a folding shunt, a positioning roller, and one or more deflection and pressure rollers. A distance between the folding strap from the folding line of the blank is adjustable, such that the folding strap acts on an outer region of the side piece.
