PURPOSE: To provide a plural pusher interval controller which prevents pushing materials from engaging thereby when simultaneously pushing a plurality of materials in a plurality of pushers for repeatedly extending forward and retracting backward within the same range.

CONSTITUTION: In a plural pusher interval controller having two or more self- overturning type pushers for pushing materials to predetermined position by repeating to extend forward and to retract backward in the same range to continuously and efficiently push the materials, the output 6 of detector for detecting the fact that the interval between two pushers becomes less than allowable value and material width information 5 are applied thereto to thereby match the materials before the respective pushers and to instruct sequence control for pushing the materials by a computer 1. This computer 1 has a sequence logic 7 for tracing the preceding side of the two pushers 3 and the following side of a master at predetermined interval to set the target position r of the pushers 3 at every sequence interval so as to thus produce forward/reverse command 10 to a drive unit 4.
