In a bag-making machine, a work unit such as a handle-applying station is independently displaceable in two directions perpendicular to one another and is driven by a drive shaft disposed at a fixed location, a propeller shaft having length compensating means connecting the drive shaft to a power input shaft for the work unit. Either the input shaft or the drive shaft is in the form of a centilever-mounted hollow shaft connected to the propeller shaft by a joint which is pivoted to an annular flange attached to the hollow shaft and which is also pivoted to a sleeve, the propeller shaft passing through the centrally free joint and through the hollow shaft, said sleeve making a positive rotary drive connection to the propeller shaft but being longitudinally displaceable thereon. |
