Title: Drying dyed skins
Inventor: KELLER HEINZ DR-ING
IPC: C14C15/00
Filed: 1969-09-01
Abstract: Dryer has three systems of conveyors. A conveyor supplies skins and an assembly of superposed endless conveyors in a drying chamber is moved by chain drive down into the chamber under phot-electric sensor control while the skins are transferred to the conveyors in succession from the skin supplying conveyor. The skins are dried for a predetermined period in the chamber and discharged on to an endless conveyor opposite the supply conveyor whilst the endless conveyors are moved progressively upwards in the chamber under photoelectric sensor control. The discharge of the skins from one endless conveyor is followed by charging of wet skins on the same conveyor, and the drying period 30544S is used for charging the supplying conveyor with a fresh batch of wet skins.
