The opening of pressed raw material bales is one of the most dangerous and laborious jobs in the mill. To break open the bale straps a worker has to split the straps or wires using an axe or crowbar. This often leads to injuries, especially with the more frequently used high density bales.  

 The OPTiCRAC offers:  

The process is explained as follows:

The bale is taken and driven to the OPTiCRAC. The fork lift presses the bale against the OPTiCRAC. The machine is automatically aligned to the bale by a pivot mounting. The two safety panels must be pressed with a force of over 72 kg to start the opening process. A carriagem which is tracked inside the machine, drives along the bale. On the carriage the sensor and the cutting unit are mounted. The radar-like sensor detects the strap or wrappings. A computer processes the signals of the sensor and controls the cutting unit. The unit is triggered when the cutting knife is precisely opposite the bale strap or wire.
