CG145 ST is a fully automating taping machine for gummed paper and is designed for taping cardboard boxes of diferent sizes. The machine receives the filled boxes coming from one or more lines via idler or powered roller beds. The spaced insertions of the boxes, the machine’s regulation of the size of the box inserted, the closing of the upper flaps and the sticking of the gummed paper above and below are fully automatic, so an operator does not need to be present.
