  • Size control system for stuffing machine
    Patent number: 4766645
    Abstract: An apparatus for controlling the stuffed casing diameter includes shoes which ride against the stuffed casing to monitor its diameter. These shoes drive a digital encoder which issues pulses representing deviations of the stuffed diameter from a predetermined nominal value. A microcomputer process these pulses and issues an appropriate control signal to a stepping motor for increasing and decreasing drag on the casing as may be needed to correct the stuffed diameter of the casing. The microcomputer can include a delay so that each stuffed product is the reference for establishing the drag characteristics of the next product to be stuffed.
