doffer 110 so that the doffed web 112 is falling by gravity along its entire width on to belt conveyor 114 to be transferred towards a condenser head not shown similar to condenser head 17 of fig1 slubbings will then be supplied to the spinning frames for the final spinning thereof and a set of spinning frames having a reduced spindle number will be used in accordance with the present invention in such a schematic illustration it was assumed that belt conveyor 114 has horizontal upper and lower runs doffed card web is falling by gravity from guide roll 15 and passing between roll pair a a 39 so that a better guide towards the condenser head not shown is obtained which is arranged on a lower floor it will be understood that when such an arrangement is used a level difference is necessary between the floors for finisher card and the unit formed by the mechanical system in accordance with the present invention see fig1 together with the spinning frames having a reduced number of spindles that arrangement may be suggested not only for supplying by gravity the doffed card web 112 on to underlying belt conveyor 114 but also where for any reason the installation of spinning machines on floors at different levels is preferred in fig5 a.
