Bags on a roll are an alternative to palletized sacks.
The ROTASAC winds the sacks on rolls using
two narrow tapes that hold the sacks in place. With a diameter of approx. 60" (1.5 meters), the finished rolls contain 3,500 – 5,000 sacks.
Depending on requirements, the
ROTASAC can work in conjunction with a bottomer using TRANSYSTEMSautomation and be integrated into the automatic production flow or it can be used off-line as a separate sack winder. The machine consists of a rotary feeder to separate the individual sacks from the stack, a shingle conveyor to transfer the sacks to the winding system, and the winding system itself.
Two winding units are incorporated and are alternately supplied with sacks. They can be moved sideways to allow for fast and easy roll changes. Once the tapes are fixed in place (either by sealing or gluing), the finished rolls are delivered to a transport pallet using hydraulically operated arms. |
