Condition: ready for operation (used), Year of construction: 2001, functionality: fully functional, product height (max.): 450 mm, product height (min.): 90 mm, product length (min.): 230 mm, product length (max.): 800 mm, product width (max.): 500 mm, product width (min.): 120 mm, Equipment: documentation/manual, The production line is a complete system suitable for packaging all types of AFH tissue paper products. The line begins with a conveyor belt which serves as a buffer. The end of the conveyor belt can be lowered, enabling the machine to handle all types of hand towels. Following the conveyor belt is an Italian-made MAC DUE stacker, which is capable of stacking toilet roll in 1, 2 or 3 layers. This is followed by another conveyor belt, which connects the stacker to the packaging machine. Next comes the CB 150A universal, fully automatic packaging machine, designed in Italy for packaging AfH tissue products. The packaging machine is highly flexible, easy to set up and operates automatically. The maximum packaging speed is 5 packs per minute. Following the packaging machine is a shrink tunnel, which is integrated into the packaging machine. The MAC DUE HMI is a new DELTA model. The CB 050A packaging machine’s PLC (OMRON) comes with a new program; the electrical cabinet was rewired in 2022, and a diagram of this has also been drawn up, which I will provide with the machine. This packaging machine’s HMI is also a new Delta model. I will provide the source programs for both the HMI and the PLC with the machine. Chjdpfxezvym To Ab Djb The production line was dismantled on 12 July 2026 due to the purchase of a new machine. The machine is packed and in storage, ready for delivery at any time. Commissioning can be arranged on request, but it is straightforward to install and I can also provide online support. Numerous videos have been made of the machine.
