This machine is a big heavy samming and setting-out machine.compared with traditional mode with four rollers .it has following features:

1.Two felt rollers、two rubber rollers and a blade roller compose five roller type samming and setting-out mechanism；

2.Every leather is to be sammed twice during one working process.therefore the leather can be sammed even dryer than before；

3.As each roller has independent driving force,so the stretching force will become even stronger. And the rate of  leather-obtaining will be increased through samming and setting-out；

4.Both blade roller and the small rubber roller adopt hydraulic swing, which greatly reduces the damage rate of the leather during the stretching process.
