A laying roller for textile yarns which, via a central air supply, supplies two air feed channels which are separated from each other. Each channel feeds air via a respective one of two porous sintered bearing bushings which are axially separated from each other. The air passing through the porous bushings builds up an air cushion for supporting a surrounding roller shell.

After a stack of sheets 5 delivered at 4 has built up on a lowering pallet (not shown), a flexible belt 21 is moved across the face of the stack so that a lateral extension 21a of the belt, initially clear of the stack, is introduced between sheets 5 across the whole width of the stack face. Continued lowering of the pallet forms a gap beneath extension 21a and an auxiliary stack holder 15 is move...

An apparent gear ratio, namely G = NT/NO, is determined based on transmission input and output revolution speeds NT and NO which are detected by sensors. The apparent gear ratio is used to determine whether a shift operation is in progress or not. It is defined that the gear shift operation is in progress when the apparent gear ratio falls between one gear ratio before the shift operation and anot...
