A laundry machine includes end frames rotatably supporting an outer casing and an inner cylinder. A coupling assembly interlocks the casing with the frame during laundry operations while the cylinder rotates, and interlocks the casing and the cylinder for simultaneous rotation, with the casing and cylinder doors aligned, for bottom unloading and top loading operations. A positioning assembly locates the cylinder, or the interlocked cylinder and casing, in a precise angular position relative to the frame so that the coupling assembly may operate. Electrical and pneumatic controls carry out laundry, unloading and loading, positioning, and coupling operations in a safe and reliable sequence.
