A device used with a conveyer weigher for automatically correcting dynamic weight signals indicative of the weights of articles successively fed to the weighing conveyer of the weigher at constant intervals, wherein the weight signal of each article is influenced by the “aftereffect”of that of the preceding article, which can automatically change the rate of correction when any article drops out from a regular interval feed line, thereby obtaining the true static weight of each article at any time.

A device for correcting dynamic weight signals provided by a conveyer weigher through a filter for removing the vibration components of said signals to obtain corresponding static weight signals, including first memory means for storing a first correction constant and arithmetic means for applying a correction computation to said dynamic weight signals based upon said first correction constant; characterized by said device further including second memory means for storing a second correction constant, means for detecting each article fed to said weigher to produce a detection signal, and selection means responsive to said detection signals for measuring the time interval between adjoining articles fed to said weigher to apply the content of said first memory to said arithmetic means when the measured value is less than a predetermined value and to apply the content of said second memory means to said arithmetic means when the measured value is greater than said predetermined value.
