Patent ID: 7670274

Claim:
A folding station of a folding box gluing machine for processing a blank delivered in a transport direction along a conveying section with a controllable delivery speed, wherein the blank has a middle piece and side pieces attached to sides of the middle piece at a folding line, the folding station comprising: a folding strap that deflects the side pieces upward and folds the side pieces; a folding shunt; a positioning roller; at least three deflection rollers; and at least one pressure roller; wherein said folding strap is guided by said folding shunt, said positioning roller, said at least three deflection rollers and said at least one pressure roller; said folding shunt, said positioning roller, said at least three deflection rollers, and said at least one pressure roller are arranged such that a distance between the folding strap and the folding line of the blank is adjustable; the deflecting of the side pieces of the blanks by the folding strap occurs in a first region from about 0 degrees to about 90 degrees by said folding shunt, the folding occurs in a third region from about 90 degrees to about 180 degrees by said at least one pressure roller, and between the first region and the third region the folding strap is guided around said at least three deflection rollers in a second region located between said first and third regions in which the side pieces of the blanks are not deflected by the folding strap; said first, second and third regions guiding the folding strap are each separately adjustable vertically and horizontally; the horizontal adjustment of the first, second and third regions includes linear displacement of the first, second and third regions in a substantially horizontal direction; at least two of the at least three deflection rollers are disposed along a transport path along which the blanks are transported and at least another one of the at least three deflection rollers is spaced away from the transport path, such that the folding strap is first guided away from the transport path and then guided back toward the transport path; and said positioning roller is arranged below a transport path of the folding station along which the blank is transported, the folding strap runs off said positioning roller and is guided across another deflection roller into the transport plane, a lengthwise axis of said positioning roller being displaced by about 90 degrees relative to a lengthwise axis of said another deflection roller, and said positioning roller is arranged to be adjusted transversely to its lengthwise axis.
