PROBLEM TO BE SOLVED: To provide a supply device capable of adjusting an interval in response to the length of a supplied material, by supplying a sheet-like material by accurately arranging a predetermined interval. SOLUTION: A corrugated board box manufacturing machine is a supply device for supplying a corrugated board sheet to a feed roller. A supply member rises in the carrying passage direction, engages with the corrugated board sheet, is sent to the feed roller and descends by separating from a carrying passage up to the next supply cycle thereafter. The supply member is an intermittent indexing mechanism by driving of a servomotor. The intermittent indexing mechanism has a driving stage of sending a sheet material to the feed roller and a stopping stage of becoming a zero speed in an output shaft of the mechanism when the supply member separates from the carrying passage. The output shaft accelerates the supply member to a higher speed than the feed roller in the driving stage, and next, decelerates to the same speed as the feed roller when the sheet material reaches the feed roller. In the stopping stage, an input shaft operated at a constant speed in the driving stage is accelerated-decelerated or decelerated-accelerated, and the supply cycle is shortened or lengthened, and the sheet material of various sizes can be supplied by minimizing a clearance or setting the clearance in zero.
