ABSTRACT:
A packaging machine has, for wrapping flat, rectangular items in a wrapper sheet, a folding, sealing and conveying apparatus including an intermittently driven turntable, a plurality of pocket assemblies on the turntable, a charging station for radially introducing an article with a wrapper sheet in between first and second walls of a pocket assembly dwelling in the charging station, a sealing station for providing a longitudinal fin seal on previously superposed flaps of the wrapper sheet, and a discharge station for radially ejecting the article from the pocket assembly dwelling in the discharge station. There is further provided an extension affixed to the first wall of each pocket assembly at an angle to the first wall. Each extension has a support face cooperating with the sealing shoe of the sealing station as a countersupport. The apparatus also has a device for rotating each pocket assembly approximately 180.degree. relative to the turntable for setting each extension into a radially relatively outward position in the charging station and a radially relatively inward position in the discharge station.
