Record cover production machine - uses supply conveyors for two cardboard sheets with several processing and forming devices and collating points

摘要

A machine producing record covers has one or two pockets made from two sheets of cardboard. The machine has a 'T' shaped frame with a longish stand with a cross stay emanating from it. Each end of the stand's length axis has a supply point with an outlet point located on the cross stay. The two supply points serve to supply a first and a second cardboard sheet respectively. There are also devices to apply notches and embossed lines into the first cardboard sheet so that the corresponding notches and embossed lines form several gluing loops with a folding point positioned next to the embossing point to fold the gluing loops into a pre-determined position.
