advantageously the roll is provided with a plurality of sections of full diameter between which sections 54 of the shaft of less diameter are supported by the aforesaid bearings as the pan 20 for example is tilted downwardly about its axis 15 as shown in broken lines at the right side of fig2 the roll within it likewise moves about the axis of the pin and becomes available for cleaning or service preferably the pans are pivotable at least 90 u00b0 or more so that their interiors will face approximately vertically and will be freely and readily available for cleaning the pans may be emptied into a drain pipe by removal of a plug 23p in the bottom at one or in any other convenient way before the pan is readied for tilting to hold the pan momentarily in horizontal position during and temporarily after removal of the securing bolts 17 and 18 a horizontal peg shaft or eccentric pin 45 is provided adjacent one end of each pan being mounted for axial sliding horizontally in a cylindrical bearing 46 supported from the machine frame 10 on a web 47 a loop 48 is provided as a handle on the outer end of the pin 45 to facilitate manual sliding to and fro when it is desired either to insert the end of the pin 45 below the pan in the path of pan movement to hold the pan or alternatively to withdraw the pin so as to free the pan for downward pivoting referring to fig3 rotation of the dye pick up rolls is caused by gearing driven by an electric motor 60 through a conventional reduction gear box shown diagrammatically at 62 the motor.
