Trunk the respective ports.  Add the three VLANs to the respective ports.  It's that easy! 
 
interface ethernet x
switchport mode trunk
switchport trunk allowed vlan add 10,20,30   #10, 20, and 30 would be whatever your VLANs are
exit

Reread his description.  He wants machines in VLANx to be able to talk to VLANx on another switch, no inter-VLAN routing.  Strictly trunking between switches.

Are the machines in the seperate vlans on different subnets? It sounds like that is the case from what you are describing. In which case just trunking the vlans between switches wont get you anywhere. You would need a layer 3 switch that can route between the vlans if this is indeed how your network is setup.
