A forming assembly of multilayer packets of wet wipes includes: a feeding device of wipes assemblies; a forming device of packets including wipes assemblies; a packet removing device, where the forming device receives the wipes assemblies from an upper level and releases the packets at a lower level; first and second bands closed in a loop, moving along a path having a respective operating section extending vertically, including blades facing one another along the respective operating section creating housings for single wipes assemblies and defining a free space; a moving index in the free space ejecting a predetermined number of wipes assemblies onto the removing device; and a movement member advancing the index through the free space, the index including a fixed body associated with the movement member and a moving portion associated with the fixed body, allowing the index height to vary with respect to the removing device.

An equipment of accumulation of sheets forms a stack of sheets on an accumulation plane by means of driving belts and diverters arranged along the path of the sheets and jump on the accumulation plane. The height of the jump is modified by shifting vertically the accumulation plane with respect to the diverters according to number and/or thickness of the sheets. The diverters can be shifted according to the length of the sheets to be accumulated, while a series of arrest lugs delimits at the rear the area of collection of the sheets and a forwarding mechanism with a pair of output rollers forwards the stack of accumulated sheets when the lugs are released.
