CG50 ST is a semi-automatic adjusting gummed paper taping machine made for taping cardboard boxes of different sizes from each other. The box is introduced manually after folding (closing) the top flaps. The machine will semi-automatically adjust to the size of the box and spread the gummed paper underneath and on top. By means of a device, it is possible to keep the machine sized to the format and thus quickly tape a quantity of equally sized boxes.
